BEFS Operator Level Tool - Agriculture residues

Crop residues

Dear Assessor,

Welcome to the Bioenergy and Food Security Operator Level Tool (Agriculture Residues).

The BEFS OLT (Agriculture Residues) covers crop and livestock specific bioenergy pathways that involve utilization of crop and/or livestock residues for energy production.

The main purpose of the BEFS OLT (Agriculture Residues) is to perform an initial screening of specific bioenergy projects to assess the projects’ environmental, social and economic performance according to good international practice. This can often be a requirement when a project developer is seeking funding for a project or when a funding institution would like to understand if a project proposal meets specific sustainability requirements. Each component of the bioenergy production value chain, namely feedstock, storage, transport, and processing is assessed in the tool against sustainability criteria. 

As a result of the assessment, the tool provides an initial indication of the projects’ sustainability identifying both strengths and weaknesses. If the outcome of the performance is not acceptable or poor, the assessment will identify which areas of the chain would need further development so as to improve the sustainability performance of the tool.

Crop residues used as bioenergy feedstock encompass a variety of different residue types. According to the location of their generation, residues can be categorised as primary or secondary. Primary residues are generated in the fields, where they are left upon harvesting and removal of the main produce. Cereal straw, corn stover and cotton stalk are examples of primary residues. On the other hand, secondary residues are generated during the processing phase of crop production and are thus located in agro-food processing facilities. Examples of secondary residues include rice husk, corn cob, sugar-cane bagasse, sunflower husk, etc. Consequently, an assessment of a bioenergy project using secondary residues does not include collection and storage components.
