Novel gasification scheme piloted for recycling of absorbent hygiene products

This article was originally posted on Chemical Engineering Online.

Summary
TU Wien is piloting an advanced gasification process to recycle post-consumer absorbent hygiene products (diapers, feminine hygiene, adult incontinence), which are notoriously hard to recycle due to composite materials like superabsorbent polymers and nonwoven fabrics, plus biohazardous waste. The approach aims to handle these complex mixed streams and boost circularity for this product category.

What do you see as the biggest hurdle to scaling this kind of AHP gasification—technical performance, cost/energy balance, regulatory approval, or public acceptance?

Post-consumer absorbent hygiene products (AHPs), such as infant diapers, feminine hygiene products and adult incontinence products, present unique challenges for recycling, because they contain compound materials like superabsorbent polymers and non-woven fabrics, as well as bio-hazardous waste, which are difficult to separate. An advanced gasification process now being piloted at TU Wien could offer a path to solve the challenge of recycling complex material mixtures and increase the circularity of this set of products.
