Recycled manure solids (RMS) are increasingly adopted in dairy farming for their economic advantages and role improving nutrient recycling waste management; however, concerns regarding greenhouse gas (GHG) emissions during storage persist. This study assessed the effects of biochar supplementation at 2.5% (2.5B) 10% (10B) compared to untreated RMS (C−) acidified (C+) on GHG (measured both continuously intermittently) characteristics a one-month period. The results showed that addition increased heavy metals concentration (with exception molybdenum) electrical conductivity RMS. Storage generally led an increase its dry matter content, except 10B treatment. significantly reduced cumulative CO2 N2O emissions, resulting 32% GWP reduction In contrast, dose higher possibly due microbial stimulation.

Continuous monitoring captured transient emission peaks, highlighting importance high-resolution assessments. Despite generated production, application bedding systems offsets these costs by mitigating increasing content. Biochar’s mitigation potential, especially doses, presents safer, multifunctional alternative aligns EU climate goals. These findings support integration into sustainable management strategies, though further research is needed optimize rates assess cost-effectiveness farming.
