Reduced life cycle climate impact from manure through catalytic methane conversion and carbon dioxide removal.

ABSTRACT: Agri-food systems constitute around one-third of global greenhouse gas (GHG) emissions, with roughly half consisting of non-CO₂ GHGs, mainly methane (CH₄) and nitrous oxide (N₂O). Methods and technologies to mitigate non-CO₂ GHGs are currently limited, which is a reason for agriculture being categorised as a hard-to-abate sector. This study examines mitigation of GHG emissions from manure storage headspace through oxidisation of CH₄ emissions at low concentrations, using a thermal catalytic process with and without subsequent CO₂ capture and storage (CCS). The technology is studied using a combination of process modelling and life cycle assessment at four CH₄ concentrations: 300, 1000, 3000 and 10,000 ppmv. The pr
