A study to define the physicochemical characteristics of biochar from manure generated on 3 different livestock farms in Malta (original) (raw)

The amounts of livestock manure produced in Malta surpasses the application rate as stipulated by the Nitrates Directive with the consequence of having an accumulation on farms. In such cases, manure becomes a liability instead of a benefit, incurring significant risk in creating environmental pollution. Pyrolysis of manure is an interesting alternative to land application, as it has the ability to render organic nitrogen into inert nitrogen gas and reduces manure biomass volumes. This technology utilises high temperature, thereby destroying any potential pathogens that may be present in the manure, has the potential of extracting useful energy and generates potentially high value products, e.g. biochar. The functions and application of biochar when used as a soil amendment to improve soil physical, chemical and biological properties depend on its structural and physicochemical properties. Such understanding is crucial for its sustainable use and application. Manure feedstock origin...
