Project Chrysalis – from container to textile

Design researcher Michelle Baggerman and material designer Jessica den Hartog present Project Chrysalis: In the Netherlands just a fraction of the 25kg of plastic waste generated p.p.p.y. is recycled. Plastics like PET and PP are increasingly recycled for high-grade applications but HDPE is mostly down-cycled. Project Chrysalis is a research into developing recycled monofilament yarns for closed-loop textile products out of HDPE sourced from household waste.

Towards textile to textile recycling: Is there a sustainable solution?

Polyester is one of the most widely used polymers all around the world, with applications that span from packaging to textiles. Depending on its use, the material composition can be quite different, with a polyester amount ranging from more than 99% for PET bottles to 25% for some textile products. The most common method for the recycling of plastic waste is mechanical recycling. This process typically includes collection, sorting, washing, and grinding of the material, but a breakdown of polymer chains occurs when the resin goes through multiple cycles, degrading its intrinsic viscosity and limiting the number of times the process can be repeated.

Trashure: from trash to treasure

Kim Poldner

Only 1% of current clothing consists of recycled textiles, while the ambition of the Dutch government for 2030 is to increase the application of recycled textiles up to 50% of all produced (textile) products. The goal is to arrive full circle with 100% circular textiles by 2050. This vision requires contemporary business models that optimally balance supply and demand. Project Trashure combines two objectives: 1. Increasing awareness about textile consumption and specifically re-appreciating textile waste. 2. Enabling commercialization of an accessible product line that uses textile waste as primary resource.

Huge Problem; we need a Holistic approach to solve it


We have talked a lot allready. We need to start doing. Consumers and producers are in the same boat. It all starts with designers and the choices they make. Stop being exclusive but work on inclusive. More transparancy is needed; why, what, where, how and when are the questions. Riskanalysis involving water, air and energy; waste and pollution are at stake. And than there is the people involved, who takes care of them. Circular means reparing which was allready wrong from the start. Cotton is the biggest problem we have to solve. A better world or a better price.

CO2 emissions saved by reusing used clothing

About 550 kilos from containers of the Foundation ‘Training and Work’ is the total weight of used clothing that has analyzed in this study characterizing the fibers that make up T-shirts, shirts, coats, pants, jackets and all kinds of clothing which are dumped in textile waste collection containers. Of the total used clothing used in the containers analyzed, 62% of the garments are reusable and 37% recyclable. As for the fibers with which the garments are made, the study concludes that cotton predominates, with 50% in the case of recyclable clothing and 60% in the case of reusable clothing.

Advertisement in the Fashion industry: what to do and what not to do when using Sustainability claims

Sustainability claims are nowadays a popular part of the promotion of fashion companies or clothing that is sold. However, when using these “sustainability claims”, you must be aware that you are bound by legislation. You cannot simply claim that your company or products are ‘sustainable’. Because of the frequent use of these claims in violation of the law, the supervisory authorities have drawn their attention to this subject.
