Biogas from wastewater’s sludge as potential resource for transportation. Experimental approach.

Abstract Considering growing energy requirements and the quest for self-sufficiency in energy sources, the utilization of waste-derived materials has surged in various fields of research in recent years. Within this framework, waste waters, sludge, or slurries, biodegradable substances, second-generation effluents, and the resulting by-products have emerged as crucial substrates of interest to produce biogas through anaerobic digestion (AD). The objective is to employ these materials as the foundation for generating renewable energy, ultimately establishing them as the primary energy source for households or industries. This paper endeavours to assess, both physically and chemically, the waste industrial and urban wastewaters sourced from west Banat region as a foundational substrate material for co-fermentation alongside residual biomass from cereals. The results obtained are presented.
