Analiza możliwości zagospodarowania profermentu z biogazowni.
Jednym z zasadniczych wymagań przy prowadzeniu biogazowni rolniczej jest prawidłowa gospodarka produktem ubocznym powstającym przy wytwarzaniu biogazu, czyli pofermentem. Regulacje prawne stanowią swojego rodzaju barierę przy wykorzystywaniu tego substratu jako nawozu w rolnictwie. W pracy omówiono kilka podstawowych możliwości zagospodarowania produktu działalności biogazowni. Słowa kluczowe: biogazownia; poferment; produkty uboczne; gospodarka odpadami

Biogas Production in Agriculture: Technological, Environmental, and Socio-Economic Aspects
This review provides a comprehensive analysis of the technological, environmental, economic, regulatory, and social dimensions shaping the development and operation of agricultural biogas plants. The paper adopts a primarily European perspective, reflecting the comparatively high share of agricultural inputs in anaerobic digestion (AD) across EU Member States, while drawing selective comparisons with global contexts to indicate where socio-geographical conditions may lead to different outcomes. It outlines core principles of the AD process and recent innovations—such as enzyme supplementation, microbial carriers, and multistage digestion systems—that enhance process efficiency and cost-effectiveness.

Kinetics and Energy Yield in Anaerobic Digestion: Effects of Substrate Composition and Fundamental Operating Conditions
This review relates the kinetics of anaerobic digestion (AD) to energy outcomes, including typical ranges of methane yields and volumetric methane productivities (down to hourly g L−1 h−1 scales relevant for industrial plants). It further translates these relationships into practical control principles that support stable, high methane productivity. Evidence spans substrate selection and co-digestion with emphasis on carbon/nitrogen (C/N) bal-ance, pretreatment strategies, and reactor operation, linking process constraints with op-erating parameters to identify interventions that raise performance while limiting inhibi-tion. Improving substrate accessibility is the primary step: pretreatment and co-digestion shift limitation beyond hydrolysis and allow safe increases in organic loading. Typical mesophilic operation involves hydraulic retention times of about 10–40 days for food waste and 20–60 days for different types of livestock manure and slowly degradable en-ergy crops, with stable performance achieved when the solids retention time (SRT) is maintained longer than the hydraulic retention time (HRT). Stability is further governed by sustaining a low hydrogen partial pressure through hydrogenotrophic methanogene-sis.
