Composting is a controlled aerobic decomposition process that converts organic residues such as fruit trimmings, pomace and vegetable hulls into stable, humus-rich material, diverting processing waste from landfill and returning nutrients to agricultural soil.
In trade practice
Food processing facilities document composting as part of their waste management plans, recording input volumes, turning frequency, temperature logs and maturity tests. Buyers auditing suppliers under organic or sustainability schemes check that compost outputs meet quality standards before land application. Common mistakes include inadequate temperature monitoring, which risks incomplete pathogen kill, and mixing non-compostable materials into the stream.
In a specification
A supplier environmental or waste management specification may require composting of defined residue categories, with records of throughput volumes and compost maturity criteria retained for audit.
