2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, Volume 5: Waste, Chapter 3: Solid Waste Disposal

Urban Farm DB summary

This IPCC guideline chapter sets out the First Order Decay (FOD) methodology for estimating methane emissions from solid waste disposal sites. The default fraction of degradable organic carbon that decomposes (DOCf) is 0.5 for bulk waste and 0.7 for food waste. For high-moisture, rapidly degradable waste such as food waste, k=0.2 (half-life of about 3 years) is indicated, versus k=0.02 (half-life of about 35 years) for dry, slowly degradable waste.

Only numbers and their conditions are stored, as structured data — never the source's own sentences. Metric and condition names stay in English, as coded.
