Abstract:

Seeking energy alternatives to replace nonreusable fossil fuels is essential to achieve circular economic in the future. Anaerobic digestion (AD) is an efficient technology for recovering such energy alternatives and valuable products from wastes including sewage sludge. However due to the inherent obstacles of this biological method, the yield of wanted products are still not sufficient. Dosing biochar into AD is an effective optimization strategy for accelerating the sludge reduction via dewatering or composting and improving the production of methane, hydrogen and volatile fatty acids (VFAs) from AD. In an attempt to understand the role of biochar in enhancing the sustainability of sludge treatment, this chapter will (1) evaluate the dewatering performance of sludge after dosing biochar; (2) discuss the role of biochar in enhancing methane from sludge digestion; (3) understand the mechanisms of applying biochar for producing higher hydrogen and VFAs; and (4) introduce the effects of biochar on sludge reduction. The outlooks about improving sustainable sludge treatment by dosing biochar are then finally proposed.
