É usado como espumas rígidas leves e é um disco rígido, plástico sólido . Devido à sua versatilidade, é usado para fabricar diversos produtos de consumo, como embalagens de alimentos, eletrodomésticos, eletrônicos, brinquedos, autopeças e equipamentos. O poliestireno também é utilizado como material de espuma, pois possui propriedades isolantes e amortecedoras. Poliestireno espuma pode ser fabricado de modo que é mais do que 95% ar , e esta forma é amplamente utilizada para o isolamento de casa e aparelho.[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”no” hundred_percent_height=”no” hundred_percent_height_scroll=”no” hundred_percent_height_center_content=”yes” equal_height_columns=”no” menu_anchor=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”https://www.earthsquad.global/wp-content/uploads/2018/07/14-58.jpg” background_position=”center center” background_repeat=”no-repeat” fade=”no” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ video_mp4=”” video_webm=”” video_ogv=”” video_url=”” video_aspect_ratio=”16:9″ video_loop=”yes” video_mute=”yes” video_preview_image=”” border_size=”” border_color=”” border_style=”solid” margin_top=”” margin_bottom=”” padding_top=”” padding_right=”” padding_bottom=”” padding_left=””][fusion_builder_row][fusion_builder_column type=”3_5″ layout=”3_5″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”rgba(255,255,255,0.88)” background_image=”” background_position=”left top” undefined=”” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”35px” padding_right=”25px” padding_bottom=”25px” padding_left=”35px” margin_top=”” margin_bottom=”0px” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=””]

Poliestireno de espuma é usado frequentemente como um material de embalagem, como amendoins de embalagem de isopor que são usados como um enchimento. Também é usado para recipientes para viagem ou para viagem e louça descartável em restaurantes. ¹ O poliestireno é usado frequentemente por essas indústrias porque é barato, prontamente disponível, branco e também reage bem a manipulação, como colagem, corte e pintura. ²

A Dow Chemical Company inventou um processo exclusivo para fabricar o seu produto de poliestireno de marca registrada em 1941. O poliestireno é um material termoplástico que se torna totalmente líquido em um ponto de fusão de 210-249 graus Celsius. Esta forma líquida permite que sejam facilmente moldadas por injeção. No entanto, o isopor também é um termofixo plásticos , o que significa que só pode ser aquecido uma vez. Aquecer o material causa uma alteração química que não pode ser revertida. O primeiro aquecimento faz com que os materiais de isopor se expandam até à sua capacidade total e, posteriormente, não podem ser reciclados para formas e utilizações futuras. ³

Os ambientalistas estão preocupados com os resíduos de poliestireno que vazam para o meio ambiente, especialmente a contaminação de água e ambientes marinhos. De acordo com Douglas McCauley, da Universidade da Califórnia em Santa Bárbara, o poliestireno pode ficar alojado em intestinos de animais marinhos, causando bloqueios. Ele também age como uma esponja poluente, captando e concentrando contaminantes no oceano. Dos animais marinhos, eles acabam de volta às nossas mesas por meio de nossa cadeia de fornecimento de alimentos. Isso faz dos resíduos de poliestireno um problema de saúde humana.

Em geral, o poliestireno não é aceito em programas de reciclagem e acaba no aterro. O poliestireno é lento para biodegradar.
5 O biodegradável descartado ao longo de centenas de anos é resistente à foto-oxidação. ⁶ O poliestireno é inflamável e pode ser facilmente inflamado, causando incêndios em aterros sanitários Emitir produtos químicos tóxicos na atmosfera.

Devido às suas características químicas, o poliestireno é essencialmente um produto de uso único e não é reciclável. Algumas cidades despertaram para o impacto ambiental dos resíduos de poliestireno de uso único em seus aterros sanitários. Nova York recentemente proibiu a posse, venda ou oferta de Espuma de Poliestireno Expansível (EPS) de uso único. “Esses produtos causam danos ambientais reais e não têm lugar na cidade de Nova York”, disse o prefeito de Nova York, Bill de Blasio. A razão para a proibição é por causa da dificuldade de reciclar EPS, o que não foi feito em larga escala.⁷Nova York segue Berkeley, Califórnia, Condado de Suffolk, Portland, São Francisco, Oakland, San José, China, Índia, Taiwan e Zimbábue, entre outros.⁸

Um desses métodos é a reciclagem térmica, que queima resíduos de poliestireno em incineradores municipais. O método foi testado e descobriu-se que deixa para trás dióxido de carbono e vapores de água. A eliminação do poliestireno, desta forma, pode ser benéfica, pois pode ser usada como combustível para programas energéticos. ⁹ Muitos municípios, especialmente na Europa, estão fazendo esses investimentos em infraestrutura.[/fusion_text][/fusion_builder_column][fusion_builder_column type=”2_5″ layout=”2_5″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_imageframe image_id=”8711″ max_width=”” style_type=”glow” stylecolor=”” hover_type=”zoomin” bordersize=”” bordercolor=”” borderradius=”” align=”center” lightbox=”no” gallery_id=”” lightbox_image=”” alt=”” link=”” linktarget=”_self” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=””]https://www.earthsquad.global/wp-content/uploads/2018/07/19-50.jpg[/fusion_imageframe][/fusion_builder_column][fusion_builder_column type=”1_1″ layout=”1_1″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=””]

Algumas empresas que precisam de embalagens de uso único também estão fazendo alterações. McDonalds e Dunkin Donuts já estão usando alternativas, mudando para o polipropileno, em vez de poliestireno. No entanto, muitas dessas alternativas são mais caras.10

As alternativas naturais para o isopor ainda estão em fase de desenvolvimento e pesquisa. Ambientalistas propuseram tudo, de cogumelos a embalagens plantáveis, amendoim comestível, fibra de bambu, turfa plástico , bem como plantas e fibras de madeira usadas para fazer pratos de papel comuns. ¹¹ No entanto, essas alternativas ainda são significativamente mais caras do que o isopor.

Devido à conscientização dos consumidores, as empresas de embalagem também estão desenvolvendo alternativas, tais como bandejas de carne compostáveis à base de milho, amendoins à base de amido feitos de milho, sorgo ou outras culturas, fibra dobrada e embalagens de polpa moldada, bem como espuma de cana-de-açúcar biodegradável. ¹²

Cabe aos empresários, consumidores e governos locais exigir alternativas aos produtos de poliestireno. As alternativas naturais e orgânicas podem ser mais caras no início, mas mais sustentáveis para o planeta a longo prazo.

泡沫聚苯乙烯通常用作包装材料，例如用作填料的聚苯乙烯泡沫塑料包装花生。它还用于餐馆的外卖或外卖容器和一次性餐具。¹聚苯乙烯经常被这些行业使用，因为它价格便宜，容易获得，颜色为白色，并且对操纵，如粘合，切割和涂漆。²

陶氏化学公司于1941年发明了一种专利工艺，使其商标聚苯乙烯产品成为“聚苯乙烯泡沫塑料”。聚苯乙烯是一种热塑性材料，在210-249摄氏度的熔点下变为完全液态。这种液体形式使它们易于注塑。但是，泡沫聚苯乙烯也是一种热固性的塑料，这意味着它只能加热一次。加热材料会导致无法逆转的化学变化。第一次加热导致泡沫聚苯乙烯材料膨胀至其全部容量，此后它不能再循环到未来的形式和用途中。³

环保主义者担心泄漏到环境中的聚苯乙烯废物，特别是水和海洋环境的污染。根据加州大学圣巴巴拉分校的道格拉斯麦考利的说法，聚苯乙烯可能会滞留在海洋动物的肠道中，造成堵塞。它也像污染海绵一样，吸收和浓缩海洋中的污染物。从海洋动物来看，它们实际上最终通过我们的食物供应链回到我们的桌子上.4这使得聚苯乙烯废物成为人类健康问题。

一般来说，聚苯乙烯不被回收计划所接受，最终进入垃圾填埋场。聚苯乙烯生物降解缓慢。⁵数百年来废弃的聚苯乙烯生物降解对光氧化有抵抗力。⁶聚苯乙烯易燃，容易点燃，导致垃圾填埋场发生火灾将有毒化学物质排放到大气中。

由于其化学特性，聚苯乙烯基本上是一次性使用的产品，不可回收。一些城市已经意识到一次性使用聚苯乙烯废弃物产品对垃圾填埋场的环境影响。纽约最近禁止拥有，销售或提供一次性可发性聚苯乙烯泡沫塑料（EPS）。纽约市市长Bill de Blasio说：“这些产品造成了真正的环境危害，在纽约市没有地位。”禁令的原因是由于难以回收EPS，而这种情况尚未大规模进行。⁷纽约市紧随伯克利，加利福尼亚，萨福克郡，波特兰，旧金山，奥克兰，圣何塞，中国，印度，台湾和津巴布韦等.⁸

然而，正在开发新方法以使用聚苯乙烯废物作为能量产生的材料。一种这样的方法是热回收，其在市政焚烧炉中燃烧聚苯乙烯废物。该方法已经过测试，发现可以留下二氧化碳和水蒸汽。以这种方式处理聚苯乙烯可能是有益的，因为它可以用作能源计划的燃料.9许多城市，特别是欧洲的城市，正在进行这些基础设施投资。

由于消费者的意识，包装公司也在开发替代品，例如玉米基可堆肥肉盘，由玉米，高粱或其他作物制成的淀粉基包装花生，折叠纤维和模塑纸浆包装，以及可生物降解的甘蔗泡沫。 12

企业主，消费者和当地政府需要替代聚苯乙烯产品。天然和有机替代品起初可能更昂贵，但从长远来看对地球来说更具可持续性。

Polystyrol ist ein synthetisches Harz. Es wird als leichte Hartschäume verwendet und ist ein harter fester Kunststoff . Wegen seiner Vielseitigkeit wird es verwendet, um eine Vielzahl von Verbraucherprodukten herzustellen, wie Lebensmittelverpackungen, Haushaltsgeräte, Elektronik, Spielzeug, Autoteile und -ausrüstung. Polystyrol wird auch als Schaummaterial verwendet, da es isolierende und dämpfende Eigenschaften aufweist. Schaumpolystyrol kann so hergestellt werden, dass es mehr als 95% Luft ist, und diese Form wird häufig für die Isolierung von Haushalten und Geräten verwendet.

Schaumpolystyrol wird oft als ein Packungsmaterial verwendet, wie Styroporpackungerdnüsse, die als ein Füllstoff verwendet werden. Es wird auch für Einweg- oder Mitnahmebehälter und Einweggeschirr in Restaurants verwendet.

Polystyrol wird häufig von diesen Industrien verwendet, weil es billig ist, leicht verfügbar ist Manipulation, wie Kleben, Schneiden und Malen. ²

Die Dow Chemical Company erfand 1941 ein eigenes Verfahren zur Herstellung ihres geschützten Polystyrolprodukts “Styropor”. Polystyrol ist ein thermoplastisches Material, das bei einem Schmelzpunkt von 210-249 Grad Celsius vollständig flüssig wird. Diese flüssige Form ermöglicht, dass sie leicht spritzgegossen werden können. Styropor ist jedoch auch ein duroplastischer Kunststoff und kann daher nur einmal erhitzt werden. Erhitzen des Materials verursacht eine chemische Veränderung, die nicht rückgängig gemacht werden kann. Die erste Erwärmung bewirkt, dass Styropormaterialien ihre volle Kapazität erreichen und danach nicht in zukünftige Formen und Anwendungen zurückgeführt werden können.

Umweltschützer sind besorgt über Polystyrol-Abfallprodukte, die in die Umwelt gelangen, insbesondere die Verunreinigung von Wasser und Meeresumgebungen. Laut Douglas McCauley von der Universität von Kalifornien Santa Barbara, Polystyrol kann in den Eingeweiden von Meerestieren untergebracht werden, was zu Verstopfungen führt. Es wirkt auch wie ein Schadstoffschwamm, der Schadstoffe im Meer aufnimmt und konzentriert. Von Meerestieren landen sie tatsächlich über unsere Lebensmittelversorgungskette wieder auf unseren Tischen.4 Dies macht Polystyrol-Abfälle zu einem Problem für die menschliche Gesundheit.

Polystyrol ist langsam biologisch abbaubar ⁵ Verworfenes Polystyrol biologisch abbaubar über Hunderte von Jahren ist resistent gegen Photooxidation. ⁶ Polystyrol ist brennbar und kann leicht entzündet werden, wodurch Brände in Deponien, die giftige Chemikalien in die Atmosphäre emittieren.

Aufgrund seiner chemischen Eigenschaften ist Polystyrol im Wesentlichen ein einmal verwendbares Produkt und nicht recycelbar. Einige Städte haben die Umweltauswirkungen von Einweg-Polystyrol-Abfallprodukten auf ihren Deponien geweckt. New York hat kürzlich den Besitz, den Verkauf oder das Angebot von expandierbarem Polystyrolschaum (EPS) für den einmaligen Gebrauch verboten. “Diese Produkte verursachen echte Umweltschäden und haben keinen Platz in New York City”, sagte New Yorks Bürgermeister Bill de Blasio. Der Grund für das Verbot ist wegen der schwierigen Recycling von EPS, die nicht in großem Maßstab durchgeführt wurde. New York City folgt Berkeley, Kalifornien, Suffolk County, Portland, San Francisco, Oakland, San Jose, China, Indien, Taiwan und Simbabwe, unter anderem. ⁸[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”no” hundred_percent_height=”no” hundred_percent_height_scroll=”no” hundred_percent_height_center_content=”yes” equal_height_columns=”no” menu_anchor=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”center center” background_repeat=”no-repeat” fade=”no” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ video_mp4=”” video_webm=”” video_ogv=”” video_url=”” video_aspect_ratio=”16:9″ video_loop=”yes” video_mute=”yes” video_preview_image=”” border_size=”” border_color=”” border_style=”solid” margin_top=”” margin_bottom=”” padding_top=”45px” padding_right=”” padding_bottom=”” padding_left=””][fusion_builder_row][fusion_builder_column type=”3_5″ layout=”3_5″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” class=”” id=””]

Es werden jedoch neue Methoden entwickelt, um Polystyrolabfälle als Material für die Energieerzeugung zu verwenden. Eine solche Methode ist das thermische Recycling, bei dem Styroporabfall in städtischen Müllverbrennungsanlagen verbrannt wird. Die Methode wurde getestet und hinterließ Kohlendioxid und Wasserdampf. Die Verwendung von Polystyrol auf diesem Wege könnte von Vorteil sein, da es als Brennstoff für Energieprogramme genutzt werden kann.9 Viele Kommunen, insbesondere in Europa, tätigen diese Infrastrukturinvestitionen.

Einige Unternehmen, die Einwegverpackungen benötigen, nehmen ebenfalls Änderungen vor. McDonalds und Dunkin Doughnuts verwenden bereits Alternativen, indem sie auf Polypropylen statt auf Polystyrol umstellen. Viele dieser Alternativen sind jedoch teurer.10

Natürliche Alternativen für Styropor befinden sich noch in Entwicklungs- und Forschungsphasen. Umweltschützer haben alles vorgeschlagen, von Pilzen bis hin zu pflanzlichen Verpackungen, essbaren Erdnüssen, Bambusfasern, Torf Plastik sowie Pflanzen und Holzfasern, die verwendet werden, um normale Pappteller herzustellen. Diese Alternativen sind jedoch immer noch deutlich teurer als Styropor.

Aufgrund des Verbraucherbewusstseins entwickeln die Verpackungsunternehmen auch Alternativen, wie kompostierbare Fleischschalen auf Maisbasis, Stärkepackungsednüsse aus Mais, Sorghum oder anderen Feldfrüchten, gefaltete Faser- und geformte Zellstoffverpackungen sowie biologisch abbaubaren Zuckerrohrschaum. 12

Unternehmer, Verbraucher und Kommunen müssen Alternativen zu Polystyrolprodukten einfordern. Die natürlichen und organischen Alternativen können auf den ersten Blick teurer, auf lange Sicht aber für den Planeten nachhaltiger sein.

Полистирол представляет собой синтетическую смолу. Он используется в качестве легких жестких пенопластов и является жестким, твердым пластиком . Благодаря своей универсальности, он используется для производства разнообразных потребительских товаров, таких как упаковка для пищевых продуктов, бытовая техника, электроника, игрушки, автозапчасти и оборудование. Полистирол также используется пеноматериалом, поскольку он обладает изоляционными и амортизирующими свойствами. Пенополистирол может быть изготовлен таким образом, чтобы он был более 95% воздуха и эта форма широко используется для изоляции дома и прибора.

Пенополистирол часто используется в качестве упаковочного материала, такого как пенополистирол, который используется в качестве наполнителя. ¹ Полистирол часто используется в этих отраслях, поскольку он недорого, легко доступен, белого цвета, а также хорошо реагирует на манипуляции, такие как склеивание, резка и покраска. ²

Dow Chemical Company изобрела патентованный процесс изготовления своего пенополистирола с товарным знаком «пенополистирол» в 1941 году. Полистирол представляет собой термопластичный материал, который становится полностью жидким при температуре плавления 210-249 градусов Цельсия. Эта жидкая форма позволяет легко лить под давлением. Тем не менее, пенополистирол также представляет собой термореактивный материал пластмассы , что означает, что его можно только разогревать. Нагревание материала вызывает химическое изменение, которое невозможно отменить. Первый нагрев приводит к тому, что материалы из пенополистирола расширяются до полной мощности, а затем его нельзя перерабатывать в будущие формы и использовать. ³

Экологи обеспокоены отходами из полистирола, которые попадают в окружающую среду, особенно загрязнением воды и морской среды. По словам Дугласа МакКоули из Калифорнийского университета в Санта-Барбаре, полистирол может попасть в кишечник морских животных, вызывая завалы. Он также действует как губка загрязнителя, собирает и концентрирует загрязняющие вещества в океане. От морских животных они фактически оказываются обратно на наши столы через нашу цепочку поставок продовольствия.4 Это делает полистирол отброшенным для здоровья человека.

В целом, полистирол не принимается в программах утилизации, и он попадает на свалку. Полистирол медленно биодеградирует. ⁵ Отброшенные биоразлагаемые полистиролы в течение сотен лет устойчивы к фотоокислению. ⁶ Полистирол является легковоспламеняющимся и может легко воспламеняться, вызывая пожары на свалках, которые выделять токсичные химикаты в атмосферу.

Благодаря своим химическим характеристикам полистирол является по существу одноразовым продуктом и не подлежит вторичной переработке. Некоторые города проснулись до воздействия на окружающую среду одноразовых отходов полистирола на своих полигонах. Недавно Нью-Йорк запретил владение, продажу или предложение одноразового использования Пенополистирола (EPS). «Эти продукты наносят реальный экологический вред и не имеют места в Нью-Йорке», – сказал мэр Нью-Йорка Билл де Блазио. Причина запрета связана с трудностью утилизации EPS, которая не была выполнена в больших масштабах. ⁷ Нью-Йорк следует за Беркли, Калифорнией, графством Саффолк, Портлендом, Сан-Франциско, Оклендом, Сан-Хосе, Китае, Индии, Тайване и Зимбабве, среди прочих. ⁸

Однако в настоящее время разрабатываются новые методы использования отходов полистирола в качестве материала для производства энергии. Одним из таких методов является термическая рециркуляция, которая сжигает отходы полистирола в муниципальных мусоросжигательных заводах. Метод был протестирован и, как установлено, оставил углекислый газ и водяные пары. Таким образом, использование полистирола может быть полезным, поскольку оно может использоваться в качестве топлива для энергетических программ. Многие муниципалитеты, особенно в Европе, делают эти инвестиции в инфраструктуру.

Некоторые компании, которые нуждаются в одноразовой упаковке, также вносят изменения. McDonalds и Dunkin Donuts уже используют альтернативы, переключаясь на полипропилен, а не на полистирол. Однако многие из этих альтернатив дороже.10

Природные альтернативы пенополистиролу все еще находятся в стадии развития и исследований. Экологи предложили все: от грибов, до плантационной упаковки, съедобных арахиса, бамбукового волокна, торфа пластика , а также растений и древесные волокна, используемые для изготовления обычных бумажных тарелок. ¹¹ Однако эти альтернативы по-прежнему значительно дороже, чем пенополистирол.

Из-за потребительской осведомленности, упаковочные компании также разрабатывают альтернативы, такие как мучные поддоны на основе кукурузы, арахис на основе крахмала, изготовленный из кукурузы, сорго или других культур, сложенного волокна и формованной целлюлозной массы, а также биоразлагаемой пены сахарного тростника. 12

Владельцам бизнеса, потребителям и местным органам власти следует требовать альтернативы продуктам из полистирола. Естественные и органические альтернативы могут сначала быть более дорогими, но более устойчивыми для планеты в долгосрочной перспективе.

El poliestireno es una resina sintética. Se usa como espumas rígidas livianas y es resistente, plástico duro . Debido a su versatilidad, se utiliza para producir una variedad de productos de consumo, tales como envases de alimentos, electrodomésticos, productos electrónicos, juguetes, autopartes y equipos. El poliestireno también se usa como espuma porque tiene propiedades aislantes y amortiguadoras. La espuma de poliestireno se puede fabricar de manera que tenga más de 95% de aire , y esta forma se usa ampliamente para aislar el hogar y el electrodoméstico.

Dow Chemical Company inventó un proceso patentado para fabricar su espuma de poliestireno expandido con la marca registrada “poliestireno expandido” en 1941. El poliestireno es un material termoplástico que se vuelve completamente líquido a un punto de fusión de 210-249 grados Celsius. Esta forma líquida hace que sea fácil verter bajo presión. Sin embargo, la espuma de poliestireno también es un termoestablematerial plásticos , lo que significa que solo se puede calentar. Calentar el material causa un cambio químico que no se puede revertir. El primer calentamiento conduce al hecho de que los materiales del poliestireno expandido se expanden a su capacidad máxima, y luego no pueden procesarse en formas futuras y utilizarse. ³[/fusion_text][/fusion_builder_column][fusion_builder_column type=”2_5″ layout=”2_5″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” undefined=”” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”0px” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”no” hundred_percent_height=”no” hundred_percent_height_scroll=”no” hundred_percent_height_center_content=”yes” equal_height_columns=”no” menu_anchor=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”center center” background_repeat=”no-repeat” fade=”no” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ video_mp4=”” video_webm=”” video_ogv=”” video_url=”” video_aspect_ratio=”16:9″ video_loop=”yes” video_mute=”yes” video_preview_image=”” border_size=”” border_color=”” border_style=”solid” margin_top=”” margin_bottom=”” padding_top=”45px” padding_right=”” padding_bottom=”” padding_left=””][fusion_builder_row][fusion_builder_column type=”2_3″ layout=”2_3″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” class=”” id=””]

Los ecologistas están preocupados por los residuos de poliestireno, que entran en el medio ambiente, especialmente la contaminación del agua y el medio ambiente marino. Según Douglas McCowley de la Universidad de California en Santa Bárbara, el poliestireno puede entrar en los intestinos de los animales marinos, causando bloqueos. También actúa como una esponja contaminante, recolecta y concentra contaminantes en el océano. De los animales marinos, en realidad se encuentran de nuevo en nuestras mesas a través de nuestra cadena de suministro de alimentos.4 Esto hace que el poliestireno se descarte para la salud humana.

En general, el poliestireno no se acepta en los programas de reciclaje y termina en el vertedero. El poliestireno tarda en biodegradarse. ⁵ El bioestreno descartado se biodegrada durante cientos de años y es resistente a la fotooxidación. ⁶ El poliestireno es inflamable y puede encenderse fácilmente, causando incendios en los vertederos que emitir productos químicos tóxicos a la atmósfera.

Debido a sus características químicas, el poliestireno es esencialmente un producto de uso único y no es reciclable. Algunas ciudades se han despertado ante el impacto ambiental de los productos de desecho de poliestireno de un solo uso en sus vertederos. Nueva York ha prohibido recientemente la posesión, venta u oferta de espuma de poliestireno expansible (EPS) de un solo uso. “Estos productos causan daños ambientales reales y no tienen cabida en la ciudad de Nueva York”, dijo el alcalde de Nueva York, Bill de Blasio. El motivo de la prohibición se debe a la dificultad para reciclar EPS, que no se ha realizado a gran escala. ⁷ La ciudad de Nueva York sigue a Berkeley, California, condado de Suffolk, Portland, San Francisco, Oakland, San José, China, India, Taiwán y Zimbabwe, entre otros. ⁸

Sin embargo, se están desarrollando nuevos métodos para usar residuos de poliestireno como material para la generación de energía. Uno de estos métodos es el reciclado térmico, que quema los residuos de poliestireno en los incineradores municipales. El método ha sido probado y se ha encontrado que deja atrás el dióxido de carbono y los vapores de agua. La eliminación del poliestireno de esta manera podría ser beneficiosa, ya que puede utilizarse como combustible para programas de energía.9 Muchos municipios, especialmente en Europa, están haciendo estas inversiones en infraestructura.

Algunas empresas que necesitan empaques de un solo uso también están haciendo cambios. McDonalds y Dunkin Donuts ya están utilizando alternativas, al cambiar a polipropileno en lugar de poliestireno. Sin embargo, muchas de estas alternativas son más caras.10

Debido a la conciencia del consumidor, las empresas de envasado también están desarrollando alternativas, como bandejas de carne compostables a base de maíz, cacahuetes de embalaje a base de almidón hechos de maíz, sorgo u otros cultivos, fibra plegada y envases de pulpa moldeada, así como espuma de caña de azúcar biodegradable. 12

Depende de los dueños de negocios, los consumidores y los gobiernos locales exigir alternativas a los productos de poliestireno. Las alternativas naturales y orgánicas pueden ser más costosas al principio, pero más sostenibles para el planeta a largo plazo.

It is also used for to-go or takeaway containers and disposable tableware at restaurants.¹ Polystyrene is used often by these industries because it is inexpensive, readily available, white in colour, and it also reacts well to manipulation, such as glueing, cutting and painting.²

The Dow Chemical Company invented a proprietary process to make their trademarked polystyrene product “styrofoam” in 1941. Polystyrene is a thermoplastic material that becomes fully liquid at a melting point of 210-249 degrees Celsius. This liquid form allows them to be easily injection molded. However, styrofoam is also a thermoset plastics, which means it can only be heated once. Heating the material causes a chemical change that cannot be reversed. The first heating causes styrofoam materials to expand to their full capacity and thereafter it cannot be recycled into future forms and uses.³[/fusion_text][/fusion_builder_column][fusion_builder_column type=”2_5″ layout=”2_5″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” undefined=”” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”0px” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”no” hundred_percent_height=”no” hundred_percent_height_scroll=”no” hundred_percent_height_center_content=”yes” equal_height_columns=”no” menu_anchor=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”center center” background_repeat=”no-repeat” fade=”no” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ video_mp4=”” video_webm=”” video_ogv=”” video_url=”” video_aspect_ratio=”16:9″ video_loop=”yes” video_mute=”yes” video_preview_image=”” border_size=”” border_color=”” border_style=”solid” margin_top=”” margin_bottom=”” padding_top=”45px” padding_right=”” padding_bottom=”” padding_left=””][fusion_builder_row][fusion_builder_column type=”2_3″ layout=”2_3″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” dimension_margin=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” class=”” id=””]Environmentalists are concerned about polystyrene waste products that leak into the environment, especially contamination of water and marine environments. According to Douglas McCauley from the University of California Santa Barbara, polystyrene can get lodged in intestines of sea animals, causing blockages. It also acts like a pollutant sponge, picking up and concentrating contaminants in the ocean. From marine animals, they actually end up back on our tables through our food supply chain.⁴ This makes polystyrene waste a human health issue.[/fusion_text][/fusion_builder_column][fusion_builder_column type=”1_3″ layout=”1_3″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” dimension_margin=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_imageframe image_id=”9032″ max_width=”” style_type=”none” stylecolor=”” hover_type=”none” bordersize=”” bordercolor=”” borderradius=”” align=”center” lightbox=”no” gallery_id=”” lightbox_image=”” alt=”” link=”” linktarget=”_self” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=””]https://www.earthsquad.global/wp-content/uploads/2018/07/poly.png[/fusion_imageframe][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”no” hundred_percent_height=”no” hundred_percent_height_scroll=”no” hundred_percent_height_center_content=”yes” equal_height_columns=”no” menu_anchor=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”https://www.earthsquad.global/wp-content/uploads/2018/07/22-17.jpg” background_position=”center center” background_repeat=”no-repeat” fade=”no” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ video_mp4=”” video_webm=”” video_ogv=”” video_url=”” video_aspect_ratio=”16:9″ video_loop=”yes” video_mute=”yes” video_preview_image=”” border_size=”” border_color=”” border_style=”solid” margin_top=”” margin_bottom=”” padding_top=”60px” padding_right=”40px” padding_bottom=”40px” padding_left=”40px”][fusion_builder_row][fusion_builder_column type=”1_1″ layout=”1_1″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”rgba(255,255,255,0.88)” background_image=”” background_position=”left top” undefined=”” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”25px” padding_right=”25px” padding_bottom=”25px” padding_left=”25px” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” class=”” id=””]

In general, polystyrene is not accepted in recycling programmes, and it ends up in the landfill. Polystyrene is slow to biodegrade.⁵ Discarded polystyrene biodegrades over hundreds of years is resistant to photo-oxidation.⁶ Polystyrene is flammable and can be easily ignited, causing fires in landfills which emit toxic chemicals into the atmosphere.

Due to its chemical characteristics, polystyrene is essentially a single use product and is not recyclable. Some cities have woken up to the environmental impact of single use polystyrene waste products in their landfills. New York has recently banned the possession, sale or offering of single use Expandable Polystyrene Foam (EPS). “These products cause real environmental harm and have no place in New York City,” said New York Mayor Bill de Blasio. The reason for the ban is because of the difficult of recycling EPS, which has not been done on a large scale.⁷ New York City follows Berkeley, California, Suffolk County, Portland, San Francisco, Oakland, San Jose, China, India, Taiwan and Zimbabwe, among others.⁸

One such method is thermal recycling, which burns polystyrene waste in municipal incinerators. The method has been tested and found to leave behind carbon dioxide and water vapours. Disposing of polystyrene in this way, could be beneficial, as it can be used as a fuel for energy programs.⁹Many municipalities, particularly in Europe, are making these infrastructure investments.[/fusion_text][/fusion_builder_column][fusion_builder_column type=”2_5″ layout=”2_5″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” dimension_margin=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_imageframe image_id=”8711″ max_width=”” style_type=”glow” stylecolor=”” hover_type=”zoomin” bordersize=”” bordercolor=”” borderradius=”” align=”center” lightbox=”no” gallery_id=”” lightbox_image=”” alt=”” link=”” linktarget=”_self” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=””]https://www.earthsquad.global/wp-content/uploads/2018/07/19-50.jpg[/fusion_imageframe][/fusion_builder_column][fusion_builder_column type=”1_1″ layout=”1_1″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” dimension_margin=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” class=”” id=””]Some companies that have a need for single use packaging are also making changes.

Due to consumer awareness, packaging companies are also developing alternatives, such as corn-based compostable meat trays, starch based packing peanuts made from corn, sorghum or other crops, folded fibre and molded pulp packaging, as well as biodegradable sugar-cane foam.¹²

It is up to business owners, consumers and local governments to demand alternatives to polystyrene products. The natural and organic alternatives may be more expensive at first, but more sustainable for the planet in the long run.
