Paddy fields emit considerable amounts of methane (CH4), which is a potent greenhouse
gas (GHG) and, thereby, causes significant environmental impacts, even as they generate …

Food production and waste management are two increasing issues ensuing from the
growing world population. Recycling organic residues into amendment for food production …

Human excreta is a valuable fertilizer for improving soil quality and crop productivity, with a
potential to replace or complement the mineral fertilizers. The main challenges related to …

This work showed for the first time that organic nutrient transformation techniques based on
locally available materials (manure, green waste and advanced biochar) can increase …

Biochar application improves soil environment and thus enhances crop yields. However, its
optimum application rate is site-and crop-specific. Our aim is to determine the optimum …

An understanding of the influence of biochar on soil organic carbon (SOC) formed from
different carbon (C) sources, other than biochar, at field scale is required to accurately …

Large volumes of sludge are produced from onsite sanitation systems in densely populated
areas (eg slums and emergency settlements) and wastewater treatment facilities that contain …

Recycling nutrients is essential for closing nutrient loops within a circular economy. Using
locally available resources such as human excreta to produce bio-based recycling fertilizers …

Human excreta are a sustainable, economical source of nutrients, and can be used to
produce recycling fertilizer for horticulture by collecting and processing the contents of dry …

During storage of urine, urea is biologically decomposed to ammonia, which can be lost
through volatilization and in turn causes significant unpleasant smell. In response, lactic acid …
