Original Abstract

The paper describes current applied research focused on heavy metal (HM) fixation in biochar after microwave pyrolysis (MP) of sewage sludge (SS). The treatment of sewage sludge is one of the most important issues in circular economy that is a part of the waste management strategy implemented by the European Union (EU) and also in the Czech Republic (CR). Disposal of SS has received significant attention mainly due to new strict regulation of the SS landfilling and direct application in agriculture. Currently, the limiting criterion of its use in agriculture is the content of heavy metals (HM), in the near future the content of xenobiotics and microplastics will also be taken into account. Thermal treatment is often associated with incineration but there are also alternative methods such as gasification or pyrolysis that produces secondary feedstock: biochar, pyrolysis oil and pyrolysis gas (Syngas). MP as a promising of the thermal treatment has an assumption for reusing SS: circular economy principles, carbon footprint reduction, water retention and HM fixation in biochar for agriculture application.
