- •
The benefits of CO2 enrichment on anaerobic digestion were evidenced.
- •
Sewage sludge and food waste anaerobic digesters were examined.
- •
First 24 h CH4 production increased 11–16% for food waste and 96–138% for sludge.
- •
A mechanism of CO2 utilisation has been hypothesised.
- •
Estimated potential CO2 reductions of 8–34% for sludge and of 3–11% for food waste.
