JaLo Biopellets Twente intends to harvest biomass from landscape elements and turn that into pellets for energy purposes. The sustainability of these future operations was assessed through a specially developed sustainability framework consisting of several tools. This NTA 8080 study takes the JaLo chain sustainability assessment one step further. It tests the chain set-up for compliance with a series of formal sustainability requirements, as documented in the Dutch 8080 standard. In addition, the project framework tools are validated against this standard; it is analysed to what extend they cover each of the NTA 8080 sustainability requirements
