A large portion of this usually non-biodegradable waste consists of single-use products such as bottles, food containers, and biscuit trays made from polyethylene terephthalate (PET), a type of plastic derived from \u2018dirty\u2019 sources such as crude oil. Most of these plastic products <a href=\"https:\/\/www.theguardian.com\/environment\/2017\/jun\/28\/a-million-a-minute-worlds-plastic-bottle-binge-as-dangerous-as-climate-change\">end<\/a> up in landfills and oceans, contaminating nature and the seafood that humans consume, while <a href=\"https:\/\/www.unilever.com\/news\/news-and-features\/Feature-article\/2018\/sanjeev-das-how-breakthrough-technology-could-significantly-reduce-plastic-waste.html\">only<\/a> 15 per cent of it reaches recycling plants. And as the scale of <a href=\"https:\/\/blog.richardvanhooijdonk.com\/en\/a-breath-of-fresh-air-turning-polluted-urban-spaces-into-tropical-forests\/\">environmental pollution<\/a> becomes increasingly evident, companies are coming up with various ways to address this problem.<\/p>\n<p>For instance, Waitrose, a UK-based supermarket chain, <a href=\"https:\/\/www.sustainablebrands.com\/news_and_views\/chemistry_materials_packaging\/sustainable_brands\/trending_unilever_co-op_waitrose_unv\">replaced<\/a> 600,000 plastic straws from its on-site cafes with paper ones. And Co-op, a British retail company, is <a href=\"https:\/\/www.sustainablebrands.com\/news_and_views\/chemistry_materials_packaging\/sustainable_brands\/trending_unilever_co-op_waitrose_unv\">planning<\/a> to use recycled plastic for its water-bottling business in a bid to reduce plastic waste by 350 tonnes annually. One of the most promising initiatives, however, is led by <a href=\"http:\/\/www.ioniqa.com\/company\/\">Ioniqa<\/a>, a Dutch startup that found a way to recycle all types of PET waste, including coloured and contaminated items, into a transparent PET plastic that can be used in food and water packaging. This technology has attracted even the attention of giants like Unilever, which plans to use it to reduce its negative environmental impact and contribute to the growth of the circular economy.<\/p>\n<h2>The Circular economy: turning waste into reusable material<\/h2>\n<p>A Circular economy strives to replace the current make-use-dispose economic model with one in which we extract the maximum value from products and materials, relying on recycling, reusing, and upcycling. If widely adopted, a circular economy <a href=\"https:\/\/www.weforum.org\/agenda\/2017\/06\/four-companies-embracing-the-circular-economy\/\">could<\/a> \u201crelease $4.5 trillion in new economic potential by 2030\u201d on a global level. And a number of companies have already started to implement this business philosophy and reap the rewards.<\/p>\n<figure id=\"attachment_3042\" aria-describedby=\"caption-attachment-3042\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-3042 size-full\" src=\"https:\/\/blog.richardvanhooijdonk.com\/wp-content\/uploads\/sites\/4\/2019\/05\/automotive-batteries.jpg\" alt=\"Stacks of used car batteries\" width=\"800\" height=\"526\"><figcaption id=\"caption-attachment-3042\" class=\"wp-caption-text\">Johnson Controls, a global producer of automotive parts, for example, has designed automotive batteries in which \u201c99% of the materials can be reused\u201d.<\/figcaption><\/figure>\n<p>Johnson Controls, a global producer of automotive parts, for example, has <a href=\"https:\/\/www.weforum.org\/agenda\/2017\/06\/four-companies-embracing-the-circular-economy\/\">designed<\/a> automotive batteries in which \u201c99% of the materials can be reused\u201d. Consumers can return old batteries that are then recycled by melting the lead and recycling plastic, and the recycled material is used in the production of new batteries. A Circular economy is also a great opportunity for startups. The Swedish startup Sellpy, founded in 2014, <a href=\"https:\/\/web.archive.org\/web\/20180628012427\/https:\/\/nordic.businessinsider.com\/from-food-waste-to-used-ikea-cupboards-here-are-6-startups-that-are-helping-sweden-tackle-the-throwaway-society--\">wants<\/a> to become the Amazon of used goods by picking up and selling products that people want to get rid of, such as clothes or furniture, and giving them 40 per cent of the profit. The company is essentially extending the useful life of products and preventing people from throwing them in the garbage. Last year, Sellpy <a href=\"https:\/\/web.archive.org\/web\/20180628012427\/https:\/\/nordic.businessinsider.com\/from-food-waste-to-used-ikea-cupboards-here-are-6-startups-that-are-helping-sweden-tackle-the-throwaway-society--\">reached<\/a> a turnover of $10,8 million, and backed by the clothing giant H&amp;M, has a promising future.<\/p>\n<p>The public sector is keen to promote the circular economy, too. Earlier this year, China and the EU <a href=\"https:\/\/www.ellenmacarthurfoundation.org\/news\/china-eu-agreement-paves-way-for-global-adoption-of-circular-economy\">signed<\/a> a joint Memorandum of Understanding on Circular Economy Cooperation in an attempt to align policies that \u201csupport the transition to a circular economy\u201d. This partnership will, hopefully, have a positive impact on the economy. It could potentially help companies from both blocks to create product standards, share recycling know-how, and <a href=\"https:\/\/resource.co\/article\/only-nine-percent-world-economy-circular-claims-global-circularity-report-12366\">improve<\/a> the existing situation, in which only nine per cent of \u201cthe world\u2019s resources are cycled back into the economy after use\u201d. And one of the most pressing challenges for the EU and China in particular, and the circular economy in general, is plastic pollution and the inability to fully recycle and reuse all types of plastics, including PET.<\/p>\n<h2>Innovative startups and corporate giants are cooperating to improve PET recycling efforts<\/h2>\n<p>The current PET recycling system typically involves shredding plastic waste into small fragments that are then cleaned, processed, and eventually used in a range of products such as clothing and carpets. But there are limitations to this method as, for example, many countries lack the infrastructure necessary to efficiently collect and sort PET waste. But even with proper infrastructure, coloured PET plastic usually can\u2019t be recycled into a material suitable for the production of food-safe packaging, as it contains traces of colour and contaminants that are hard to remove. Ioniqa\u2019s technology, however, might be a solution to this problem.<\/p>\n<p>It relies on a proprietary magnetic smart material that changes its properties when exposed to a stimulus such as a magnetic field. It acts as a catalyst in the process of depolymerisation, breaking down PET from its complex polymer structure into smaller molecules called <a href=\"http:\/\/www.ioniqa.com\/applications\/\">monomers<\/a>, <a href=\"https:\/\/www.unilever.com\/news\/news-and-features\/Feature-article\/2018\/sanjeev-das-how-breakthrough-technology-could-significantly-reduce-plastic-waste.html\">absorbing<\/a> colour and impurities from shredded PET waste in the process. The end result is a liquid that\u2019s dried into a powder form and used to produce food-safe transparent PET plastic.<\/p>\n<figure id=\"attachment_3044\" aria-describedby=\"caption-attachment-3044\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-3044 size-full\" src=\"https:\/\/blog.richardvanhooijdonk.com\/wp-content\/uploads\/sites\/4\/2019\/05\/PET-recycling-system.jpg\" alt=\"PET recycling machine\" width=\"800\" height=\"526\"><figcaption id=\"caption-attachment-3044\" class=\"wp-caption-text\">The current PET recycling system typically involves shredding plastic waste into small fragments that are then cleaned, processed, and eventually used in a range of products such as clothing and carpets.<\/figcaption><\/figure>\n<p>Meanwhile, Ioniqa has signed an agreement to supply the powder-like material to Indorama, a petrochemical company, which will turn it into PET resin. In the next stage, the resin will be shipped to Unilever that <a href=\"https:\/\/www.unilever.com\/news\/news-and-features\/Feature-article\/2018\/sanjeev-das-how-breakthrough-technology-could-significantly-reduce-plastic-waste.html\">will use<\/a> it to produce bottles for drinks and beauty products. David Blanchard, the chief research and development officer at Unilever, <a href=\"https:\/\/www.webwire.com\/ViewPressRel.asp?aId=222233\">says<\/a> that \u201cThis innovation is particularly exciting because it could unlock one of the major barriers today \u2013 making all forms of recycled PET suitable for food packaging.\u201d<\/p>\n<p>And as Unilever <a href=\"https:\/\/www.unilever.com\/news\/news-and-features\/Feature-article\/2018\/sanjeev-das-how-breakthrough-technology-could-significantly-reduce-plastic-waste.html\">plans<\/a> to have all of its plastic packaging \u201creusable, recyclable or compostable by 2025\u201d, Ioniqa also has big plans. This Dutch company is building its first PET-recycling factory that should begin operation in the summer of 2019 and start shipping around 10,000 tons of its new PET powder material each year. That output is small compared to the market demand, but Tonnis Hooghoudt, Ioniqa\u2019s CEO, <a href=\"http:\/\/www.ioniqa.com\/13-september-2018-ioniqa-launching-first-pet-plastic-up-cycling-plant\/\">explains<\/a> that they\u2019ll eventually scale up the production to 100,000 or 200,000 tons. Also, they\u2019ll license the technology to other businesses to increase the use of this recycling method. As for the future, Hooghoudt notes that the company will work on developing recycling techniques for other types of plastics.<\/p>\n<h2>Coca-Cola fights plastic pollution<\/h2>\n<p>Much like Unilever, Coca-Cola also has plans to increase the use of recycled plastic in its packaging. In fact, this beverage giant hopes that by 2030, its packaging will be <a href=\"https:\/\/www.ptonline.com\/news\/coca-cola-invests-in-pet-recycling-initiatives-\">made<\/a> of at least 50 per cent recycled materials and that <a href=\"https:\/\/www.ptonline.com\/news\/coca-cola-invests-in-pet-recycling-initiatives-\">it\u2019ll<\/a> \u201crecycle a bottle or can for every one the company sells\u201d. To achieve these goals, Coca-Cola is financially supporting companies like Ioniqa and plans to supply its bottling factories with 100 per cent recycled PET plastics. In addition to this, it <a href=\"https:\/\/www.ptonline.com\/news\/coca-cola-invests-in-pet-recycling-initiatives-\">contributed<\/a> $15 million to Circulate Capital, a venture loan fund that supports companies and infrastructure projects that combat plastic waste in oceans.<\/p>\n<p><iframe title=\"Circular PET Recycling, a game changer\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/fkk5KrPNApk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>But environmental groups like Greenpeace aren\u2019t impressed by these moves as they claim that drink companies such as Coca-Cola, PepsiCo, and Nestle <a href=\"https:\/\/www.reuters.com\/article\/us-coca-cola-plastic\/coke-pepsi-nestle-top-makers-of-plastic-waste-greenpeace-idUSKCN1MJ1FM\">are<\/a> some of \u201cthe world\u2019s biggest producers of plastic trash\u201d. In fact, companies like these <a href=\"https:\/\/www.theguardian.com\/commentisfree\/2018\/jun\/09\/recycling-plastic-crisis-oceans-pollution-corporate-responsibility\">produce<\/a> around 500 billion single-use plastic bottles each year, and as Annie Leonard, the executive director of Greenpeace USA, <a href=\"https:\/\/www.theguardian.com\/commentisfree\/2018\/jun\/09\/recycling-plastic-crisis-oceans-pollution-corporate-responsibility\">says<\/a>, \u201cthere is no way that we can recycle our way out of a problem of that scale\u201d. Instead, it\u2019s essential that the production of new plastic products is reduced. Parallel with that, Coca-Cola could use recycled material for the 3,400 bottles it <a href=\"https:\/\/www.theguardian.com\/environment\/2017\/jun\/28\/a-million-a-minute-worlds-plastic-bottle-binge-as-dangerous-as-climate-change\">produces<\/a> each second and stop increasing the amount of plastic waste on the planet. This plan, unfortunately, has a major flaw as currently <a href=\"https:\/\/www.theguardian.com\/environment\/2017\/jun\/28\/a-million-a-minute-worlds-plastic-bottle-binge-as-dangerous-as-climate-change\">there\u2019s<\/a> \u201cnowhere near enough high quality [recycled] food grade plastic available on the scale that was needed\u201d to replace throwaway bottles. That\u2019s why the spread of technologies like the one made by Ioniqa is crucial in increasing our capacity to produce food-grade plastics from recycled materials.<\/p>\n<h2>Retailers curb the use of throwaway plastics<\/h2>\n<p>In addition to food and drink manufacturers, retailers are also fighting plastic pollution. For instance, Waitrose, a UK supermarket chain, will replace the 600,000 plastic straws it needed every year with paper straws, and it will <a href=\"https:\/\/www.sustainablebrands.com\/news_and_views\/chemistry_materials_packaging\/sustainable_brands\/trending_unilever_co-op_waitrose_unv\">offer<\/a> \u201cnon-plastic cutlery and drink stirrers made from wood\u201d. Also, the company steadily eliminated non-recyclable materials from its production process, and now, 80 per cent of the packaging in its products is <a href=\"https:\/\/www.sustainablebrands.com\/news_and_views\/chemistry_materials_packaging\/sustainable_brands\/trending_unilever_co-op_waitrose_unv\">considered<\/a> recyclable. Co-op, another British retailer, is planning to use recycled plastics in its water bottling business and <a href=\"https:\/\/www.sustainablebrands.com\/news_and_views\/chemistry_materials_packaging\/sustainable_brands\/trending_unilever_co-op_waitrose_unv\">hopes<\/a> to remove black and dark-coloured plastics from its aisles by 2020. The reason for this move is that PET waste-sorting machines can\u2019t efficiently detect darker plastics, which then end up in landfills with other unsorted and non-recyclable materials. Lastly, Co-op has even developed a biodegradable paper tea bag to reduce plastic waste caused by UK\u2019s favourite drink.<\/p>\n<h2>Increasing efforts to solve our plastic waste problem<\/h2>\n<p>Most PET plastics that humans produce ends up in landfills and oceans, polluting the environment and finding its way even to our plates. The scale of environmental disaster is alarming and companies are ramping up their efforts to improve plastics recycling processes. Ioniqa has made serious advances in that regard by inventing tech that makes any PET plastic suited for recycling and ensures that it can be used as food-safe packaging.<\/p>\n<p>But it will take much more to clean up our planet. Manufacturers need to reduce the production of single-use plastics and ensure their supply chain adheres to the principles of the circular economy. \u2018Recycle and reuse\u2019 should become a new motto for companies, as we can no longer afford to ignore the plastic waste that\u2019s drowning our planet. Many entrepreneurs and public institutions have already supported the development of the circular economy, which is also a major growth factor for global business.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Circular economy: turning waste into reusable material Innovative startups and corporate giants are cooperating to improve PET recycling
