Paper: “Near-term potential of organic waste management infrastructure for soil carbon sequestration in rangelands,” 2022 Environ. Res.: Infrastruct. Sustain. 2 045007.
Research Team: A L Hall, M D Potts, and W L Silver
Findings: The multi-objective spatial optimization results indicate considerable carbon sequestration benefits in the range of −1.9 ± 0.5 MMT CO2eq annually, by applying compost to 6 million hectares of California rangelands at a price of approximately $200 per ton, presenting a cost-effective climate change mitigation strategy within proposed federal sequestration credits. Expanding composting capacity is predicted to increase the total amountof carbon sequestered while reducing the cost per ton and per hectare treated. This model aids decision makers in considering the technical, economic, and institutional potential of actively managing the State’s organic materials in municipal waste streams for climate change mitigation.
