- Caveats
- While diversion of organic waste to composting and anaerobic digestion is increasing, it remains a minority practice compared to landfilling in the United States, and its potential to displace synthetic fertilizer is limited.
- Hand review
- D2 EU: 17% of municipal waste composted or digested in 2018, up from 11% in 2004 (EEA data); US EPA-reported programme grew composting from ~0.6 Mt to ~10 Mt (2013–2020).

| The amount of organic waste collected for composting in the United States increased from approximately 622,000 tons in 2013 to about 10.3 million tons in 2020. “A portion of the 72,000 MTCO2e net reduction in the waste sector over these years is attributable to the reduced landfilling of organic waste, as the amount of organic waste collected for composting increased from about 622,000 tons in 2013 to about 10.3 million tons in 2020.” United States · 2013-2020 · minority but measured share or volume | government or intergovernmental ✓ www.epa.gov |
| Diverting the inedible half of food waste to anaerobic digestion is estimated to account for slightly over half of the potential 55.45 MMT CO2e reduction in net methane emissions from food waste. “Granted, halving food waste by redistributing the edible half is a huge undertaking and would be responsible for almost half of that reduction (27.5 MMT, or 49.6% of the 55.45 MMT reduction), but diverting the inedible half to ADs is an even larger com ponent, accounting for slightly over half (50.4%) of the reduction.” United States · 2024 · | weak (company, news, market research, other) ✓ energy-vision.org |

Replaces: landfilling of organic waste · Scope: municipal and commercial biowaste · Evidence: moderate
The chemical problem#
- Food and garden waste is the largest single fraction of municipal waste. In a landfill it rots anaerobically and releases methane and contaminated leachate for decades.
- Mixed with other waste, it also makes recycling and incineration less efficient.
Product overview#
Separate collection plus biological treatment:
- Composting (windrows, tunnels, in-vessel) produces compost for agriculture and horticulture (CE01 peat replacement).
- Anaerobic digestion produces biogas or biomethane (EN01, EN04) and digestate fertiliser (NU03).
The EU Landfill Directive (1999) and the Waste Framework Directive (mandatory separate biowaste collection from 2024) drive the shift.
Active ingredient / Composition#
- Microbial consortia of composting (thermophilic bacteria and fungi) or anaerobic digestion (hydrolytic, acidogenic and methanogenic archaea).
- Outputs: compost, digestate, biogas/biomethane.
Key facts#
| Parameter | Value |
|---|---|
| EU share | 17 % of municipal waste composted or digested in 2018, up from 11 % in 2004 (EEA data) |
| EU growth | Composted/digested municipal waste +52 % (2004–2018) (EEA data) |
| US example | Organic waste collected for composting rose from ~622,000 t (2013) to ~10.3 Mt (2020) in an EPA-reported programme |
| Driver | Landfill restrictions, separate-collection mandates, methane targets |
| Caveat | A large share of biowaste still ends up in mixed waste |
Advantages#
- Cuts landfill methane and leachate at source.
- Returns organic matter and nutrients to soil (NU03, CE01) and produces renewable gas (EN01).
- Proven at municipal scale with off-the-shelf technology.
Mode of action#
Composting: aerobic microbial degradation heats the pile to 55–70 °C, sanitising and stabilising the material into humus-rich compost. Digestion: microbes convert organic matter without oxygen into methane and CO₂; the residue is a nutrient-rich digestate.
Application#
| User | Target | Method, timing and specifics |
|---|---|---|
| Municipalities | Landfill diversion | Separate biowaste bins + composting or AD plant |
| Food industry and retail | Commercial food waste | Contracts with AD plants; depackaging lines |
| Farms and horticulture | Soil inputs | Certified compost and digestate |
Limitations#
- Collection is the bottleneck: contamination (plastics) and low participation limit capture.
- Compost markets need quality standards and certification.
- Displacement is partial: most biowaste in many countries is still landfilled or incinerated.
Evidence of displacement — D2: measurable displacement (minority share)#
Assessment (hand-reviewed): EU: 17% of municipal waste composted or digested in 2018, up from 11% in 2004 (EEA data); US EPA-reported programme grew composting from ~0.6 Mt to ~10 Mt (2013–2020).
Verified figures (the number is in the quoted sentence and the sentence is on the source page):
- displacement — The amount of organic waste collected for composting in the United States increased from approximately 622,000 tons in 2013 to about 10.3 million tons in 2020. (United States, 2013-2020; government or intergovernmental: epa.gov)
- displacement — The share of municipal waste composted and digested in the EU increased from 11% in 2004 to 17% in 2018. (EU, 2004-2018; weak: bbia.org.uk)
- displacement — The amount of municipal waste that is composted or anaerobically digested increased by 52% between 2004 and 2018. (EU, 2004-2018; weak: bbia.org.uk)
- performance — Diverting the inedible half of food waste to anaerobic digestion is estimated to account for slightly over half of the potential 55.45 MMT CO2e reduction in net methane emissions from food waste. (United States, 2024; weak: energy-vision.org)

Bioeconomy value#
Biological treatment is steadily taking biowaste out of landfills — 17 % of EU municipal waste and rising after collection mandates — turning a methane source into compost, fertiliser and gas.
