ACT Efficiency Formula is: ACT Efficiency = Eproducts bio/(Ebio + Einputs bio) where: Eproducts bio is the energy from Biomass in the Advanced Fuel which is produced from the material to which Ebio relates; Ebio is the energy from Biomass in the material from which the Advanced Fuel to which Eproducts bio relates was produced; Einputs bio is any energy used in the production of the Advanced Fuel to which Eproducts bio relates;
