In this study, the environmental impacts associated with the generation of electricity from anaerobic digestion (AD) of agricultural waste have been evaluated using life cycle assessment. Four AD plants are considered with the installed capacity ranging from 100 to 300 kW. They are fed with agricultural waste, such as animal slurry, potato peel, tomato skin and seeds, and a small amount of maize silage. The results suggest that the plants fed with waste and maize silage have higher impacts than those using only waste.

Abstract
In this study, the environmental impacts associated with the generation of electricity from anaerobic digestion (AD) of agricultural waste have been evaluated using life cycle assessment. Four AD plants are considered with the installed capacity ranging from 100 to 300 kW. They are fed with agricultural waste, such as animal slurry, potato peel, tomato skin and seeds, and a small amount of maize silage. The results suggest that the plants fed with waste and maize silage have higher impacts than those using only waste.
