A basic mass and energy balance calculation was completed using the experimental results obtained from the analysis of the feedstock and biochars. The mass and energy balance results are shown in Table 9 for MGW. The energy balances show that 41% of the energy in the green waste feedstock was transferred into syngas during the pyrolysis processing.
