Transforming residues from meat processing into engineered soil amendments

该项目的目的是将肉类加工的有机残留物转化为农业土壤改良剂，积极改善养分保留并减少一氧化二氮(一种强有力的温室气体)排放。目前肉类加工残留物的处置和处理方案在经济上和环境上都是不可持续的。在这项研究中，将开发一种改进的水热碳化工艺，将有机残留物转化为新型氢化碳。然后，将使用稳定同位素示踪、遗传特征和数值模拟来评估这些氢化碳对土壤养分保持和一氧化二氮产生的影响。该项目将降低有机废物处理的经济和环境成本。

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.
