The meeting was the\u00a0latest edition of the Chemical Sciences and Society Summit (CS3), which takes place every two years.<\/p>\n Plastics\u2019 worst environmental impacts are a common sight in the news or on social media, but they also play crucial roles in producing renewable energy and\u00a0reducing the environmental impact of transport, as well as preserving fresh food and protecting it from contamination.<\/p>\n Plastics have also played a lifesaving role during the ongoing COVID-19 pandemic \u2013 as personal protective equipment such as masks, gowns and gloves all contain\u00a0plastic.<\/p>\n A report on the findings, published today, says that with plastics likely to play a crucial role in healthcare and in low-carbon technologies in the future, it\u2019s vital that new\u00a0types of plastic are designed that can fulfil those roles without adverse impact on the environment. The report was published by the\u00a0Chemical Society of Japan and JST partnership with an international group of learned societies and funding bodies.<\/p>\n Professor Charlotte Williams, Professor of Chemistry at the University of Oxford, who chaired the meeting, said:<\/p>\n \u201cWe use plastics because they can do things other materials cannot. We have an opportunity and an obligation to think about how we can re-design plastics to make\u00a0them fully sustainable and fit for purpose, both for existing applications and for those we will need tomorrow. In the process, we must aim to reduce and even reverse\u00a0some of the damage plastic pollution has already caused.<\/p>\n \u201cThe solution cannot be to \u2018ban\u2019 plastics or to replace them with alternative materials like paper, glass or metals. \u00a0These alternatives also involve significant\u00a0environmental impacts and in some cases are less sustainable than using plastics.<\/p>\n \u201cBuilding a new future for plastics will require extensive collaboration across disciplines \u2013 including science, engineering, social sciences, policy, regulation and\u00a0business.\u201d<\/p>\n Future sustainable technologies may depend on plastics<\/p>\n Plastics are frequently demonized \u2013 often for the waste and pollution they cause \u2013 but they have benefits too.<\/p>\n In the future many technologies central to reducing our reliance on fossil fuels will depend on plastics. Wind turbine blades require plastic composites and adhesives,\u00a0while batteries rely on plastics in their housing and may even apply them as electrolytes and other components. Plastics are also widely used in home insulation,\u00a0reducing energy usage, and they play critical roles in the construction sector as pipes and conduits, cladding, seals, adhesives and gaskets.<\/p>\n Other future technologies such as robotics, drones, electronics, healthcare and diagnostics will also rely on the development of better plastic materials.<\/p>\n Plastic\u2019s image problem exists in the production stage too, since most plastics are made from petrochemicals, the extraction of which causes pollution and the\u00a0degradation of land. But in future they could be produced from more sustainable sources \u2013 such as from waste plastics or biologically sourced raw materials.<\/p>\n Chemistry has a central role to play<\/p>\n Technical solutions are urgently needed to ensure that in future plastics can retain their useful properties, whilst having a reduced environmental impact throughout\u00a0their lifespan. Chemistry will play a central role in delivering these solutions.<\/p>\n Developments in chemistry will be key to understanding and mitigating the impact of plastics in the environment. Chemistry can help to develop efficient ways to\u00a0recycle the plastics we use today and, in the longer-term, create replacements that are made from sustainable starting materials, are more amenable to recycling at\u00a0end of life, and degrade more quickly to harmless by-products if they escape into the environment.<\/p>\n Four major research challenges<\/p>\n The new report \u2013 which is the output of a global summit held at the Royal Society of Chemistry in November 2019 \u2013 identifies four major research challenges. These\u00a0four challenges are interlinked and are of equal importance.<\/p>\n \u2022 Understand the impacts of plastics throughout their life cycles.\u00a0We need a suite of technologies and assessment tools to improve sustainability throughout\u00a0plastics life cycles \u2013 from obtaining raw materials and manufacturing plastics, to better recycling and disposal options and fully understanding all the\u00a0environmental impacts. Analytical methods and predictive models will be key to understanding the structure, properties and behaviour of micro and nanoplastics\u00a0currently in the environment. \u30ed\u30f3\u30c9\u30f3\u306e\u738b\u7acb\u5316\u5b66\u5354\u4f1a\u306e Burlington House \u3067\u958b\u50ac\u3055\u308c\u305f Chemical Sciences and Society Summit\uff08CS3 \u56fd\u969b\u5316\u5b66\u30b5\u30df\u30c3\u30c8\uff09\u306e\u767d\u66f8\u304c2020\u5e746\u67083\u65e5\u306b\u516c\u958b\u3055\u308c\u307e\u3057\u305f\u3002\u9ad8 […]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[2],"tags":[],"class_list":["post-12199","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/posts\/12199","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=12199"}],"version-history":[{"count":0,"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/posts\/12199\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=12199"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=12199"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cm.kyushu-u.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=12199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

\n\u2022 Develop new sustainable plastics.\u00a0New plastics must be designed with circular economy in mind from the design stage. This involves designing polymer\u00a0structures with specific properties that allow plastics to be manufactured, processed and recycled with minimal negative environmental impacts.
\n\u2022 Closed loop plastics recycling.\u00a0More efficient recycling processes are needed across the board \u2013 including in separating mixtures and composites into single\u00a0pure polymers, and in enabling \u2018chemical recycling\u2019 \u2013 that is breaking polymers down into smaller molecules for future use.
\n\u2022 Understand and control plastic degradation. The indiscriminate disposal of plastics into the environment must be stopped. Some degradable plastics will be\u00a0needed and the focus should be on developing products that are both recyclable and environmentally degradable so they can be degraded to non-toxic\u00a0biochemicals after multiple reuse or recycles. \u00a0It is also important that labelling standards are improved to ensure clarity and standardization of terms such as\u00a0compostable, biodegradable and degradable polymers.
