gewebemüll

Gewebemüll is a term used primarily in German-speaking countries to describe waste material that consists largely of animal and plant tissue. The category includes everything from trimmed or discarded parts of livestock such as meat, bone, organs, and other edible tissues, to processed animal by‑products used in manufacturing of leather, feed, or pharmaceuticals. In the consumer context it also covers organic kitchen remains from home cooking, as well as discarded subsistence by‑products from fisheries and forestry.

The composition of gewebemüll is predominantly biodegradable, with a high content of proteins, lipids, and connective tissue. Depending on its source, the material may also contain trace amounts of minerals, heavy metals, or microbial pathogens. Because the tissue is nutrient‑rich, it can support the growth of bacteria and parasites, which poses a risk if it is handled without adequate hygiene measures.

Regulation and treatment of gewebemüll varies by country. In the European Union, it is classified as “secondary raw material” and is permissible for use in animal feed only after rigorous safety testing, as set out in regulations such as the EU Food Hygiene Regulation. In Germany, the “Datenblatt für die gültige Verwertung von tierischen Abfällen” gives detailed guidance on how to store, transport, and process tissue waste. The primary disposal methods are composting, anaerobic digestion to produce biogas, and incineration with energy recovery. Recycling streams often target the production of feedstuffs, starches, or fat extracts, although the market for such recycled products remains limited due to safety concerns and market sensitivity.

Because gewebemüll can act as a vector for zoonotic diseases, authorities require that it be collected separately from household organic waste. Collection is typically done through special containers or by professional waste carriers. Proper segregation, storage at low temperatures, and sanitary handling are essential to prevent the spread of pathogens. Effective treatment of gewebemüll can reduce landfill usage and recover valuable resources, contributing to a more circular bio‑economy.
