Life cycle analysis (LCA) allows for evaluation of the environmental costs of production systems from creation to disposal. Many LCA studies are available for various renewable energy production systems, however, there is a need for LCAs that quantify the benefits of energy coproduction systems. Coproduction systems refer to a partnership of energy production systems that reciprocate waste products in a mutually beneficial way, thereby decreasing waste streams and offsetting input streams from both systems. This study evaluates how biomass crop coproduction with an anaerobic digestion (AD) system affects the life cycle greenhouse gas emissions and material waste streams relative to standalone bioenergy systems. A literature meta-analysis was used to collect life cycle inventories, emissions, and cost for: 1) Advanced biofuel production from perennial grass, 2) Biogas production from AD. The reduction in emissions due to coproduction was 0.28 kgCO2eq per kWh electricity produced. Life cycle impacts were most influenced by the following categories: facility construction, harvest and lignin use, transportation and biorefinery, and effluent, fertilizer, and soil. The cost for coproduction of biogas from food waste and bioethanol from perennial grass was reduced by 10.8% and 7.0%, respectively, when compared to the cost for individually managed systems.
