TL;DR: In this article , the authors analyzed the supply chain associated with the energy recovery of agroforestry woody residual biomass to clarify the positive and negative points affecting the viability and feasibility of energy recovery projects.
Abstract: Agroforest woody residual biomass can play an essential role in the decarbonization of energy production and in meeting the targets imposed for carbon neutrality. However, due to the constraints caused by some intrinsic characteristics, such as its low density, low calorific value, high heterogeneity and territorial dispersion, its management hampers in the collection and transport processes for recovery. In this article, the supply chain associated with the energy recovery of agroforestry woody residual biomass is analyzed to clarify the positive and negative points affecting the viability and feasibility of energy recovery projects. For this purpose, a PEST and a SWOT analysis were carried out. It was identified that the main constraints are related with the economic aspects, which are directly depending on the optimization of the entire supply chain, from the cutting operations, passing through the intermediate tasks (which may or may not add value), and transport to the final destination for energy recovery.
