ABSTRACT
The growing intensity of animal farming necessitates composting technologies that are
both environmentally and economically sustainable. This study evaluates four mainstream
aerobic composting methods: static heaps (SH), windrow composting (WC), membrane-covered
composting (MC), and reactor composting (RC), using an integrated life cycle assessment (LCA)
and cost-benefit analysis. Results show that MC significantly outperformed the others in eco-efficiency
(EE). It enhanced environmental performance by 41.8%, 25.4%, and 13.2% compared to SH, WC,
and RC, respectively (p<0.01 for SH; p<0.05 for WC and RC). These gains were driven by substantial
reductions in greenhouse gas (GHG) emissions (44.9%, 32.7%, and 17.8%) and eutrophication potential
(38.6%, 29.1%, and 15.3%) relative to SH, WC, and RC. Economically, MC’s operational cost (USD
28.84 t-1) was 33.6% lower than that of RC, underscoring its cost-effectiveness for emission-intensive
systems. Consequently, MC’s overall EE improved by 168.4%, 92.7%, and 39.6% over SH, WC,
and RC, respectively. We conclude that membrane-covered composting presents a balanced
and compelling strategy for advancing sustainable waste management in intensive livestock operations.
