Biomass use system is consisted of 1) production or generation, collection, transportation and storage of feedstock biomass, 2) conversion of the feedstock biomass to demand-oriented material and energy (renewal resources), 3) storage, transportation and use of the renewal resources, and 4) adequate disposal at above respective stage. This paper arranged the discussion points on evaluation methods of new biomass use scenarios in terms of lifecycle cost and lifecycle fossil energy consumption. An evaluation format was proposed. The evaluation clarifies the structure of cost and energy for a planned biomass use scenario. The results will provide an suitable project cycle management by cost saving and mitigation of global warming. The analysis from lifecycle view is important to ensure the sustainability of biomass use system.
