文摘

Recycled biomass only contains the emergy stored in its organic matter. A formula is proposed to account real contribution of recycled waste for planting. A case on wheat-maize system fertilized by five types of wastes is performed. Recycling agricultural systems show a lower emergy efficiency. Recycling agricultural systems show a higher sustainability.
