Recovery of Cellulose, Extracellular Polymeric Substances and Microplastics from Sewage Sludge: A Review

Wastewater treatment plants are considered to be not only as facilities, but also essential elements of the circular economy. can chains economy cycle. Despite this, sewage sludge management and utilization mostly limited biodegradation further agricultural uses or incineration. The recovery valuable products is mainly nitrogen phosphorus compounds. Fewer analyses focus on generating, recovering, removing various polymers from sludge, such cellulose extracellular polymeric substances (EPS). On other hand, contains pollutants, microplastics. use biopolymers significant considering problems connected with presence effects artificial (microplastics) in environment. technical possibilities, many scale installations operated. Law regulations should make some incentives develop technologies sell recovered market waste material, a product. This paper presents state-of-the-art for selected polymers’ including parameters processes possible applications products, it considers possibility microplastics’ removal this material.
