    Abstract

    Little is known about the potential contribution to climate change mitigation of hydrochars - new biomaterials derived from organic waste – when used as soil amendments in agriculture. Hydrochars have fundamentally similar properties to more common biochars, although they degrade faster in soils which might obviate some climate benefits. In addition, current indicators of climate change like global warming potentials (GWP) commonly used in greenhouse gas (GHG) accountings, are not fully suitable to hydrochars. Here, we address these challenges and present results of a life cycle assessment (LCA) combined with recent climate metrics (i.e. dynamic global warming potentials and climate tipping potentials) carried out to quantify potential contribution to climate change mitigation of hydrocarbons varying in stability in agricultural soils.
