Abstract (en)

[origin: WO2021154088A1] A process of producing soil amendment from organic waste by feeding wet organic waste (101) with biochar (118) and wood (102) to form a feed mixture (106) to a composting drum (107) where The mixture is subjected to microbial aerobic conversion to produce a solid phase(108) comprising compost, biochar and water, and a gaseous phase(119) comprising humid air, CO2 and ammonia. Moisture in solid phase(108) is removed in a dryer (109) to produce dry compost (110), which is fed to a separator (111) to extract structural material from compost.Compost in conduit (112) is fed to a mixer (113), and mixed with an aqueous solution (121) containing ammonia from scrubber (120) and composting drum (107) and other components to produce fertilizer(114). A pyrolysis reactor (123) converts structural material (101) and waste (102) to a gaseous phase and a carbonaceous solid phase (126)for use as carbon source in the fertilizer (114, 115).
