This study aims to provide a comprehensive analysis of Indonesian biomass and biomass residues by considering the contributions of ecological goods and services using exergy calculations, and utilizing a number of aggregate metrics that developed from Indonesian biomass and biomass residues consumption. In this regard, the chemical exergy values of eighteen kinds of biomass and biomass residues in Indonesia were calculated in this article. The goal is to identify desirable attributes that may serve as the basis for decision making for future biofuel options. Calculations showed that the chemical composition of biomass and biomass residues influences strongly the chemical exergy values (e(CH)). High proportions of oxygen, compared to carbon or hydrogen, generally reduce the chemical exergy of these biomass samples. In this paper, the calculated exergy values of biomass and biomas residues will be useful for energy experts studied in biomass area and biomass-fired powerplants.
