Abstract:

Biomass residues use in circular economy is aimed to get significant GHG emission reductions to tackle against climate change. Olive pruning debris, in Andalusia region, is commonly used (50%) as inert cover on field to protect against erosion and to provide nitrogen and carbon to the soil. The installation of a local bio-refinery using olive pruning residues as feedstock could be a good example of circular economy application enhancing sustainability of goods produced and improving local economy. However, the conversion of the residue into a raw material generates a change in the agriculture management with negative consequences on soil carbon sequestration. The paper analyses the living cover crops plantation function as a mitigation strategy to improve carbon sequestration in olive groves combined with the use of olive pruning residues in a bio-refinery. The paper analyses the function of the living cover crops as a mitigation strategy to improve carbon sequestration in olive groves combined to the use of olive pruning residues in a bio-refinery. The main conclusion of the study is the bio-refinery systems analyzed save GHG emissions in all the cases. The selected cover crop specie is of high relevance in the GHG balance.
