Production of agricultural biogas from waste – an element of socially responsible actions in the food sector

Abstract

The agricultural and food sector accounts for substantial volumes of organic waste (such as livestock excreta, meat offals) considered as onerous on the environment. The above decomposes formulating methane, carbon dioxide and hydrogen sulphide in anaerobic conditions. Methane produced in digester chambers of a biomass plant (called biogas) may be applied for the production of electricity and heat, powering of vehicles as well as injections into gas networks. Biogas is one of the renewable sources of energy. In the light of the EU's sustainable development and climate neutrality policies, increasing the share of renewable sources in overall energy consumption is a priority for the Member States. For this reason, the article examines one of the renewable energy sectors in Poland, which is agricultural biogas production. The main attention was focused on agricultural biogas plants. Most often used substrates for biogas production, the dependence of biogas plant location on the population living in particular regions (voivodships) and the development of agriculture in their territories were analysed. The main purpose of the article was to indicate the reasons for the failure of the agricultural biogas plant construction program in Poland. Literature and document analysis were performed, interviews with waste producers as well as owners of agricultural biogas plants were carried out, and SWOT analysis was prepared.

Valorisation of Agri- and Aquaculture Residues via Biogas Production for Enhanced Industrial Application

“…Furthermore, when the biogas adaptation approach is extended beyond the electricity and biofertiliser production and to include the cooling energy production for industrial use or the renewable natural gas [15], the level of penetration of Brazilian and other markets can be even bigger. Besides the end-use side, also the feedstock side can be widely enlarged by involvement of fish residues [16] beyond the traditional poultry residues, manure [33], and food wastes [34]. It is because the biogas production from fish-type feedstock garners more and more attention, chiefly since literature data demonstrates that the biogas production rate from fish is as efficient as from poultry manure, i.e., 370 mL/g vs. 390 mL/g, respectively [35].…”

Comprehensive wheat straw processing with deep eutectic solvent to deliver reducing sugar and lignin streams

“…Lignocellulosic biomass has garnered considerable interest due to its potential as a bioenergy and biomaterials source and as an abundant renewable resource [3,4]. To minimize land use and to avoid competition with food resources, waste biomass from numerous economic sectors, e.g., agriculture, offers signi cant potential [5][6][7].…”

“…Finding renewable raw materials for the production of fine chemicals, materials, and fuels has become an important goal [7,8]. Lignocellulosic biomass is a promising alternative to fossil resources due to its abundance, renewability, and versatility [7].…”

Lignocellulosic biomass is one of the most abundant renewable resources on Earth and its use does not increase net CO 2 emissions [9].…”
