Abstract. Agricultural, fishery, forestry and agro-processing activities produce large quantities of residues, by-products and waste materials every year. Inappropriate disposal and inefficient use of these resources contribute to greenhouse gas emissions and non-point pollution, placing significant environmental and economic burdens on society. Since many nations do not keep statistics on these materials, it has not been possible to accurately quantify the amounts produced, their competing uses and the quantities potentially available for recycling at a local level. Therefore, the objectives of the present work were to provide (1) definitions, typologies and methods to aid consistent classification, estimation and reporting of the various residues and by-products, (2) a global organic matter database (OMD) of residues and by-products from agriculture, fisheries, forestry and related industries and (3) regional and global estimates of residues and by-products potentially available for use in a circular bio-economy. To the best of our knowledge, the OMD is the first of its kind to consolidate quantities and nutrient concentrations of residues and by-products globally from agriculture, fisheries, forestry and related industries (available at https://doi.org/10.5281/zenodo.10450921; Sileshi et al., 2024). The OMD will be updated continuously as new production data are published in FAOSTAT and country-specific conversion coefficients become available. This information is expected...
