- ... Studies show that source separated human excreta have a fertilizing potential with benefits to plant growth and crop yield similar or exceeding that of mineral fertilizers. The main challenges in fertilizing with excreta are pathogens, and an increased risk of eutrophication of water bodies in case of runoff. This review shows that lactic acid fermentation of excreta reduces the amount of pathogen ...

- ... This work seeks to extend the knowledge on the effect of chemical treatment of sewage sludge digestate (SSD)-derived biochar for the As(III and V) and Cd(II) sorption ability using potassium hydroxide (KOH) or hydrogen peroxide (H2O2). Results showed the increases of the pH of point of zero charge, the Brunauer-Emmett-Teller (BET) surface area and cation exchange capacity (CEC) after chemical trea ...
