When we hear the word plastics today, one of the lasting images in our minds is that of a plastic bag floating in the ocean. This is largely because of the unprecedented rise in single-use applications and a mindset as consumers to just use and throw.<\/strong><\/p>\n<h3>What are the advantages and disadvantages of plastics?<\/h3>\n<p>It is critical to not lose sight of the value plastics bring and the various industries that depend on this important material. Plastics have proven their merit in terms of mechanical properties, performance, versatility, cost, etc. For example, plastics are a key material of choice in the fight against the COVID-19 pandemic across the world. The health risk, especially for the medical professionals and frontline workers, would be higher without plastics in PPE kits, masks and gloves.<\/p>\n<p>The way plastics are currently produced, consumed and managed at the end-of-life, however, is not completely sustainable. Talks of replacing plastics with other recyclable materials, such as paper, especially in packaging applications, have gathered pace due to the negative environmental impacts of\u00a0linear plastics production,\u00a0the high volume of\u00a0single-use\u00a0applications, and the\u00a0mismanagement of waste\u00a0over the years.\u00a0Plastics circularity\u00a0and\u00a0waste valorization\u00a0are the need of the hour and chemical recycling technologies can play a vital role in achieving the same.<\/p>\n<h3>Recycling plastics<\/h3>\n<p>Clearly, it is not possible to continue with business as usual, and all those across the plastics value chain must adopt\u00a0circular principles.<\/p>\n<p>One part of the solution to achieve plastic circularity is the\u00a0recycling of plastics\u00a0but the current recycling rates are far from ideal levels.

The project focuses on developing new technology to\u00a0chemically recycle plastic waste. Together with Servizi di Ricerche e Sviluppo (S.R.S.),\u00a0Eni\u2019s chemical company\u00a0is developing a\u00a0cost-effective\u00a0valorization process of mixed plastic waste that cannot be mechanically recycled.<\/p>\n<h3>What is chemical recycling of plastics?<\/h3>\n<p>Chemical recycling, an umbrella term for several advanced technologies, can convert plastic waste into raw materials that re-enter the value chain to produce new polymers.\u00a0CEFIC, the European Chemical Industry Council, has broadly categorized these technologies into three types.<\/p>\n<p><strong>Pyrolysis<\/strong>\u00a0is one of the leading processes being explored today to meet the challenging recycling targets and address the need for plastic circularity. The process occurs at high temperatures (in the absence of oxygen) and converts plastic waste into feedstock that is further used in manufacturing new chemicals.<\/p>\n<p>Versalis\u00a0is advancing the development of pyrolysis technology via <a href=\"https:\/\/hoopproject.eu\/\" target=\"_blank\" rel=\"noopener\">Project Hoop<sup>\u00ae<\/sup><\/a> and to understand more about the mission and vision, I spoke to\u00a0<strong>Fabio Assandri<\/strong>, Research and Innovation Technology Director at Versalis.<\/p>\n<h3>Q: Could you explain Project Hoop<sup>\u00ae<\/sup>\u00a0and why Eni is investing in it?<\/h3>\n<p><strong>Assandri<\/strong>:\u00a0Plastic waste is a challenging issue we all face today. Europe collects close to 30 million tonnes of post-consumer plastic waste and\u00a0recycles only one-third of it\u00a0as of now. Mechanical recycling is the primary method used and it efficiently manages pre-sorted waste streams (e.g., mono-material, less contaminated, etc.). A good example is PET water bottles.<\/p>\n<p>However, mechanical recycling has certain limitations. Reprocessing steps lead to degradation in material properties and may lead to downcycling. It also puts a cap on the number of times the plastic gets recycled. And, perhaps the biggest drawback is the\u00a0inability to manage more complex and mixed plastic waste streams, which currently are either incinerated or landfilled.<\/p>\n<p>This led us to invest in <a href=\"https:\/\/hoopproject.eu\/\" target=\"_blank\" rel=\"noopener\">Project Hoop<sup>\u00ae<\/sup><\/a>\u00a0which focuses on\u00a0chemical recycling\u00a0as an alternative solution to the problem, thereby advancing plastic circularity.<\/p>\n<h3>Q: How does Hoop<sup>\u00ae<\/sup> work?<\/h3>\n<p><strong>Assandri<\/strong>:\u00a0Hoop, the name of the project, represents a complete circle and aptly symbolizes the support for circularity. We&#8217;ve worked on a new process based on\u00a0pyrolysis technology\u00a0from S.R.S. that transforms polymers into smaller molecules and building blocks. This conversion is analogous to dismantling a lego set into individual blocks.<\/p>\n<p>We have completed pilot-level testing and also the design of the demonstration plant with a capacity of\u00a06,000 tonnes per year\u00a0at the Mantova\u2019s site. Our goal is to scale up and have the technology ready for application on a large scale.<\/p>\n<h3>Q: What is plasmix? And what are the advantages of pyrolysis technology?<\/h3>\n<p><strong>Assandri<\/strong>:\u00a0Plasmix is the mixed plastic waste that is not suitable for an effective mechanical recycling and accounts for a significant amount of plastic waste that currently doesn&#8217;t get recycled.<\/p>\n<p>Pyrolysis is ideal for such waste streams and it allows for the\u00a0materials to stay in use longer, which aligns with circular economy principles. Because the quality is same as virgin plastics, chemically recycled grades can find use in high-value applications, including\u00a0food-contact applications.<\/p>\n<p>The process we&#8217;ve developed offers added benefits like flexibility, energy efficiency, quality of products, and large saving of greenhouse gas (GHG) emissions.\u00a0Material recovery of all the streams\u00a0resulting from the pyrolysis process (liquid, gas, and solid) is a high priority for us.<\/p>\n<h3>Q: Can chemical recycling reduce fossil fuel dependency and lower CO<sub>2<\/sub> emissions?<\/h3>\n<p><strong>Assandri<\/strong>:\u00a0Overall, the\u00a0carbon footprint\u00a0of chemical recycling is lower than the upstream and downstream emissions in the current linear system (raw material extraction, plastic production, and end-of-life waste management). Currently, mixed plastic waste is either\u00a0incinerated or landfilled\u00a0and both have a negative environmental impact.<\/p>\n<p>Incineration leads to an increase in the emissions of CO<sub>2<\/sub> and other pollutants, while landfilling causes plastic waste to further leach into the environment. Chemical recycling avoids these issues and since it converts the waste back into raw materials, it helps\u00a0reduce the dependence on fossil reserves.<\/p>\n<h3>Q: Will mechanical recycling fade with the development of chemical recycling plants?<\/h3>\n<p><strong>Assandri<\/strong>:\u00a0Not at all. Mechanical recycling is already a sizable business with a well-developed ecosystem for polymer streams like PET, HDPE, PP, etc. There is no point in replacing existing systems that work well.<\/p>\n<p>The aim of the project is\u00a0to complement mechanical recycling\u00a0and drastically improve the circularity of plastic products by widening the scope of recyclable waste streams. In fact, I believe that mechanical recycling will benefit from the development of chemical recycling technologies as the targets and assessments would be more spread out between the two.<\/p>\n<h3>Q: Is the Hoop<sup>\u00ae<\/sup> process the solution to the plastic waste issue?<\/h3>\n<p><strong>Assandri<\/strong>:\u00a0The issue of plastic waste is complex and requires a\u00a0multi-level approach\u00a0to find effective solutions. Projects like Hoop<sup>\u00ae<\/sup> are taking steps in the right direction and are an important part of the solution. Whether or not chemical recycling, together with mechanical recycling, will succeed in addressing plastic waste issues depends on several factors:<\/p>\n<ul>\n<li>all actors\u00a0across the value chain,\u00a0including brand owners, need to get involved and collaborate;<\/li>\n<li>consumers must also play an important role in supporting the proper waste collection and in increasing the\u00a0demand for recycled products;<\/li>\n<li>standardized\u00a0certifications\u00a0that are internationally recognized are a necessity. Because chemical recycling generates virgin-equivalent feedstock, the materials will get blended in chemical plants and make it difficult to physically track the recycled feedstock. Experts, therefore, suggest using the\u00a0mass-balance approach\u00a0to accurately trace the flow of the recycled material around industrial plants in order to allocate the correct value of recycled content to a product.<\/li>\n<\/ul>\n<p>Last but not least, the industry will also need\u00a0political and regulatory support. More clarity on\u00a0sustainable plastics manufacturing\u00a0should come in early 2021 once the European Commission completes its review of the EU&#8217;s Taxonomy Regulation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-84949\" src=\"https:\/\/renewable-carbon.eu\/news\/wp-content\/uploads\/2021\/02\/single-image-versalis-hoop-chemical-recycling-plastic-1024x726.png\" alt=\"single-image-versalis-hoop-chemical-recycling-plastic\" width=\"578\" height=\"410\" srcset=\"https:\/\/renewable-carbon.eu\/news\/media\/2021\/02\/single-image-versalis-hoop-chemical-recycling-plastic-1024x726.png 1024w, https:\/\/renewable-carbon.eu\/news\/media\/2021\/02\/single-image-versalis-hoop-chemical-recycling-plastic-300x213.png 300w, https:\/\/renewable-carbon.eu\/news\/media\/2021\/02\/single-image-versalis-hoop-chemical-recycling-plastic-600x425.png 600w\" sizes=\"auto, (max-width: 578px) 100vw, 578px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h3><em>About the author<\/em><\/h3>\n<p><em> An independent consultant and published writer with a Master\u2019s degree in Chemistry and 12 years of experience in the specialty chemicals industry.
