The aim of this project is to transform organic residues from meat processing into agricultural soil amendments that actively improve nutrient retention and reduce nitrous oxide (a potent greenhouse gas) emissions. Current disposal and treatment options for meat processing residues are economically and environmentally unsustainable. In this research, a modified hydrothermal carbonisation process will be developed to transform organic residues into novel hydrochars. The influence of these hydrochars on soil nutrient retention and nitrous oxide production will then be assessed using stable isotope tracing, genetic characterisation, and numerical modeling. The project will reduce the economic and environmental costs of organic waste disposal.

该项目的目的是将肉类加工产生的有机残留物转化为农业土壤改良剂，积极改善养分保持和减少一氧化二氮（一种强效温室气体）排放。目前肉类加工残留物的处置和处理方案在经济和环境上都是不可持续的。在本研究中，将开发一种改进的水热碳化过程，将有机残留物转化为新型的碳氢化合物。这些氢焦对土壤养分保持和一氧化二氮生产的影响，然后将使用稳定同位素示踪，遗传特性和数值模拟进行评估。该项目将降低有机废物处理的经济和环境成本。
