Humification evaluation and carbon recalcitrance of a rapid thermochemical digestate fertiliser from degradable solid waste for climate change mitigation in the tropics.

Indiscriminate, unhygienic and unscientific disposal of solid wastes poses significant risks leading to soil, water and air pollution. Abiotic and nonenzymatic rapid thermochemical processing technology provides a solution for the management of degradable solid waste at the source, converting it to organic digestate fertiliser within a day, thus overcoming the main drawback of the long time span required for composting. A study was performed to evaluate the maturity parameters and the extent of humification of the thermochemical digestate fertiliser and the raw biowaste substrate.
