This enables a fully circular textile chain within the textile-to-textile and banner-to-banner recycling principle. The technology prevents dyed polyester textiles from being incinerated or landfilled after use and allows for high-quality recycling without the use of water or harmful chemicals. To put this into numbers: in 2022, polyester accounted for approximately 54% of the global fiber market, with a volume of around 63.3 million tons, most of which are currently incinerated or landfilled after use.<\/p>\n<p>The goal of the project is to develop and validate a sustainable decolorizing method that makes recycled polyester suitable for reuse in clothing and textile products. This tackles one of the biggest challenges in textile recycling: removing dyes to enable the reuse of textiles without limitations in color options.<\/p>\n<p>The end results include:<\/p>\n<ul>\n<li>A decolorizing machine for decolorization using supercritical CO&#8322;. <\/li>\n<li>New circular textile products, such as newly colored recycled polyester for clothing and reused banners. <\/li>\n<li>Life cycle analysis (LCA) and cost analysis to quantify ecological and economic benefits. <\/li>\n<li>Demonstration projects and market validation aimed at the commercial application of the technology.<\/li>\n<\/ul>\n<p>Through cross-border collaboration between the Netherlands and Germany, the project contributes to a more sustainable textile industry with lower CO&#8322; emissions and more efficient resource use.<\/p>\n","protected":false},"parent":0,"template":"","pr-category":[275],"pr-priority":[288],"pr-stat":[254],"class_list":["post-43199","projects","type-projects","status-publish","hentry","pr-category-high-tech-systems-materials-htsm-3","pr-priority-a-more-innovative-programme-area","pr-stat-new"],"acf":[],"_links":{"self":[{"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/projects\/43199","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/projects"}],"about":[{"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/types\/projects"}],"wp:attachment":[{"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/media?parent=43199"}],"wp:term":[{"taxonomy":"pr-category","embeddable":true,"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/pr-category?post=43199"},{"taxonomy":"pr-priority","embeddable":true,"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/pr-priority?post=43199"},{"taxonomy":"pr-stat","embeddable":true,"href":"https:\/\/deutschland-nederland.eu\/en\/wp-json\/wp\/v2\/pr-stat?post=43199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
