Valorization of food waste and poultry manure through co-composting amending saw dust, biochar and mineral salts for value-added compost production

The present study proposes a system for co-composting food waste and poultry manure amended with rice husk biochar at different doses (0, 3, 5, 10%, w/w), saw dust, and salts. The effect of rice husk biochar on the characteristics of final compost was evaluated through stabilization indices such as...
