First LCA of anaerobic co-digestion in the context of a municipal waste service.
AcoD shown to have the least environmental impact across all categories, excluding human toxicity.
Increasing specific biogas production by 50 m3 shows GWP decrease by at least 2.5%.
Food waste sorting efficiency, carbon storage and other sensitivities are assessed.
Uncertainty analysis confirmed that co-digestion always had the smallest GWP.
