Enhancing methane yield and microbial resilience in olive pomace anaerobic digestion via co-digestion with pig manure.

ABSTRACT:

Background

Intensive agricultural practices are increasing the generation of by-products and wastes, which require appropriate management strategies to prevent environmental pollution and recover valuable resources. Waste-to-energy technologies, such as anaerobic digestion, are gaining attention for integrating local feedstocks to produce biofuels and biofertilisers, contributing to closed nutrient cycles. In the Mediterranean region, olive pomace is very abundant, but its intrinsic characteristics hinder the production of biogas via anaerobic digestion. Concurrently, the direct application of untreated pig manure on agricultural land continues to pose significant environmental risks.

Results

This study assessed the biomethane potential of olive pomace and pig manure, along
