Biomass in agriculture are residues of crops (residues that remains in the field after harvest) that are comprised from different parts of plants (stems, branches, leaves, husks and seeds). These are very useful sources of energy whose potential, at the moment, is quite neglected in BiH. This residues can be used to produce energy and falls into the following categories:
1. Crop residues:
-Residues after the harvest
2. Animal farming residues:
-Animal waste (fertilizers)
3. Residues from perennial crops:
-Small branches and other woody residues after regular maintenance of the perennial crops, such are olive groves, orchards and vineyards.
It is estimated that approximately 1/3 of crop remains can be used to produce energy (thermal and electrical). The other 2/3 of the remains can be used in livestock farms as bedding for livestock or left on the land as a fertilizer.The analysis of the livestock and crop waste shows large untapped potential for energy generation; however, most farms are small and do not have sufficient available biomass quantities to make investment in a biomass plant worthwhile.
