They are considered environmentally compatible because they can be recycled. However, a plastic must have a purity level of at least 96 % to be recyclable.<\/p>\n<p style=\"text-align: justify;\">Currently, about half of all polyolefin plastic waste is mechanically recycled, while the remainder is recovered for energy. The association \u201cPolyolefin Circular Economy Platform\u201d (PECP), a forum for all stakeholders in the polyolefin value chain, has set itself the goal of promoting the circular economy for polyolefins. Among its targets are the optimization of collection and sorting systems and achieving a recycling rate of around 75 % for polyolefin packaging by 2030.<\/p>\n<p style=\"text-align: justify;\">A higher recycling rate can be achieved through improved separation of plastic waste. Researchers at Aarhus University, in cooperation with the Danish companies Vestforbr\u00e6nding, Dansk Affaldsminimering Aps, and PLASTIX, have developed a \u201cnew camera technology capable of distinguishing between 12 different types of plastic\u201d<sup>[2]<\/sup> \u2013 with higher accuracy than the near-infrared (NIR) spectroscopy currently used. This allows for greater purity of the separated plastic fractions.<\/p>\n<figure id=\"attachment_8530\" aria-describedby=\"caption-attachment-8530\" style=\"width: 450px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-8530 size-full\" title=\"Only single-grade plastic waste can be mechanically recycled\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2024\/03\/Kunststoffabfaelle.jpg\" alt=\"Only single-grade plastic waste can be mechanically recycled\" width=\"450\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2024\/03\/Kunststoffabfaelle.jpg 450w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2024\/03\/Kunststoffabfaelle-300x200.jpg 300w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><figcaption id=\"caption-attachment-8530\" class=\"wp-caption-text\"><center>Only single-grade plastic waste can be mechanically recycled<\/center><\/figcaption><\/figure>\n<p style=\"text-align: justify;\">A different approach is being pursued by trinamiX GmbH, a subsidiary of BASF AG and provider of mobile spectroscopy. It offers a \u201chandheld kit\u201d comprising a portable NIR spectrometer, a smartphone, data analysis in the trinamiX spectroscopy cloud, real-time access to results via a mobile app, and documentation in the customer portal<sup>[3]<\/sup>. This enables the sorting of plastic waste even in regions without dedicated sorting technology. Another important contribution to the polyolefin circular economy is the industry trend toward in-house recycling, where production waste is reprocessed in company-owned regranulation plants.<\/p>\n<pre><strong>Text sources: \r\n<\/strong>[1]: https:\/\/www.marketdataforecast.com\/market-reports\/europe-plastics-market\r\n[2]: https:\/\/www.chemie.de\/news\/1174212\/durchbruch-bei-der-trennung-von-kunststoffabfaellen.html \r\n[3]: https:\/\/www.basf.com\/global\/de\/media\/news-releases\/2022\/11\/p-22-400.html <strong> \r\n\r\nImage sources:<\/strong> \r\nHeader image | \u00a9 danielskyphoto \u2013 stock.adobe.com \r\nGiulio Natta | Unknown (Mondadori Publishers), Public domain, via Wikimedia Commons \r\nPlastic waste | \u00a9 arnaudmartinez \u2013 stock.adobe.com<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>The term polyolefins refers to polymers produced from alkenes such as ethene, propene, butene, 2-methylpropene, and 4-methyl-1-pentene.
