DePoly is a company with a mission: to create a sustainable circular economy for plastics with an innovative chemical process<\/a> that breaks down plastics into reusable raw materials. Currently at the industrial demonstration stage, this technology could significantly increase the proportion of recycled plastics in the world. <\/strong><\/p>\n\n

Fifty-two percent of worldwide CO2 <\/sub> emissions are linked to plastics. And only nine percent of plastics are currently recycled, with the rest either being incinerated or going into landfill. In response to this appalling state of affairs, DePoly<\/a>, a spin-off of the EPFL Valais\/Wallis<\/a>, has developed a promising solution for managing plastic waste. It uses a chemical reaction to break down plastics into reusable raw materials. \u201cOur process can be used to recycle pre-consumption, post-consumption and post-industrial plastics \u2013 not just PET but also PLA (polylactic acid), PBT (polybutylene terephthalate) and PU (polyurethane),\u201d says Samantha Anderson<\/a>, DePoly\u2019s co-founder and CEO. This process, known as depolymerisation, involves breaking the chemical bonds in plastic to obtain a liquid, monoethylene glycol (MEG) and a powder, terephthalic acid (PTA), which are then used to make new PET that is identical to the original material. The process requires no pre-washing or pre-sorting. <\/p>\n\n

\u201cThe materials generated from these polymers are the same as those that are currently produced by the oil industry,\u201d says Samantha Anderson. But there\u2019s a big difference: this new process cuts CO2<\/sub> emissions, reduces the amount of waste plastics (and microplastics), and lessens our dependence on the oil industry. And because it works at ambient temperature, the process developed by DePoly has the additional advantage of reducing the energy required to produce recycled PET by nearly two-thirds compared to making \u2018virgin\u2019 PET. <\/p>\n\n

The pilot phase proved that this chemical process works \u2013 and works well. A demonstration plant in Switzerland, due to be up and running by 2025, will process around 500 tonnes of PET a year. The first industrial installation should be operational by 2027-2028. In the longer term, DePoly plans to roll out its technology beyond Switzerland\u2019s borders. \u201cWe\u2019ve been working on proof-of-concept projects with companies in Europe, the United States, Japan, South Korea and Mexico,\u201d adds Samantha Anderson. In 2020, an initial round of fundraising brought in CHF 1.3 million, followed by a seven-figure investment in 2023. <\/p>\n\n

The potential is enormous. Samantha Anderson stresses that all PET waste that can\u2019t be recycled mechanically could theoretically be handled by this process. \u201cWe are helping businesses achieve their sustainability goals by supplying them with recycled raw materials with a lower carbon footprint (CO2<\/sub>) than oil-based products,\u201d she says. \u201cOur solution copes easily with contaminants, so we can also re-direct plastics that would otherwise be incinerated into this recycling process.\u201d <\/p>\n\n
