This study assesses the technical, agronomic and techno-economic feasibility of producing biogas from DOW using a simplified anaerobic digestion approach based on pH monitoring and controlled digestate recirculation. A 0.1 m<sup>3</sup> biodigester previously inoculated with rumen and cow dung was operated under mesophilic and tropical climate conditions, evaluating hydraulic retention times (HRT) of 30 and 60 days and a digestate recirculation ratio of approximately 16% to stabilize pH. Experimental results demonstrate that DOW can be effectively converted into biogas under low-technology operating conditions, achieving stable methane production without the need for advanced monitoring or strict control of multiple physicochemical variables. A HRT of 60 days showed improved performance compared to 30 days. Methane concentration averaged 56.3%, which, although lower than that of cow dung biogas, is sufficient for energy generation using commercially available engines. Digestate reuse promoted successful vitroplant acclimatization without the need for inorganic fertilization, highlighting its agronomic potential. By combining experimental operation with an empirical numerical model, this work provides practical indicators for assessing digestion performance under variable feedstock conditions typical of municipal food waste. Environmental assessment indicates avoided CO₂ emissions on the order of 600–3300 tCO₂·year<sup>−1</sup> for a 1-MW plant, depending on operational assumptions and emission factors. Techno-economic analysis shows payback periods ranging from 4 to 9 years and 6–22 years; and internal rates of return between 10.8%–18.5% and 19%–31%, with plant factors of 33.3% and 60%.

To address this, our study used a food-energy nexus lens to explore people's experiences of the cooking journey, i.e., decision-making regarding which fuel to use, obtaining fuel and then cooking using that fuel. We videoed ‘go along’ interviews with residents of two African informal settlements during their cooking journeys. Interviews with 15 participants in Mukuru (Kenya) and 15 in Ndirande (Malawi) were analyzed using thematic analysis. Participants' decision-making regarding fuel use was complex, dynamic (considering short-to-long timescales) and context-specific. Participants were aware of some of the household air pollution (and other solid fuel-related) health risks, though there were some misconceptions. The use of waste materials in solid fuel cooking – particularly during ignition – was common. The ‘cooking journey’ framing in this study highlighted the range of risks and challenges experienced across the food-energy nexus beyond household air pollution, including terrain, the built environment and gender-based violence. Broader approaches to understanding the contexts, cultures and behaviours of fuel users in informal settlements, such as our ‘cooking journey’ approach, can support better intervention design, and therefore enable progress towards sustainable development goal 7 - access to affordable, reliable, sustainable and modern energy for all.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"91 ","pages":"Article 101914"},"PeriodicalIF":4.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145791479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the analyses and evidences on implications of the non-energy policies on RE development are scarce, especially in the context of developing countries. This study provides a comprehensive, stakeholder-informed assessment of 43 national-level policy instruments across five domains in the Philippines: Energy Policy and Regulation, Climate Change and Sustainability, Environmental and Natural Resource Conservation, Agriculture and Rural Development, and Land Use and Property Rights. In this study, using a modified Sustainable Development Goals (SDG) interaction framework, stakeholders from academia, government, industry, and non-governmental organizations evaluated each policy's influence on RE development using a seven-point scale. Weighted average (WA) scores were computed to determine whether policies act as enablers or constraints. Results show that energy and climate policies are strongly supportive due to clear mandates and institutional coordination, whereas land governance and agrarian reform policies are viewed as restrictive because of procedural uncertainty and tenure risks. Environmental policies are generally enabling but raise permitting concerns. Divergent stakeholder perceptions underscore the need for inclusive and transparent governance.

Firstly, salt cavern hydrogen storage (SCHS) is still in its infancy, and it is crucial to identify key risks and implement preventive measures to minimize unnecessary losses. Secondly, relying on a single model has proven insufficient for risk assessment in this emerging domain.

It is designed for a 2-day autonomy, ensuring continued functionality even in adverse conditions, and features an in-built protection against overcharging, over-discharging, and short circuits. Provision for grid operation is included, with flexibility for users to select preferred power sources, ensuring reliability under varying weather conditions. This scalable and holistic system is also suitable for households in post-disaster situations when electricity is scarce, with or without the use of booster pumps.

To address this, an abundant agricultural byproduct, banana peel (BP), and cruciferous vegetable waste (CL–cauliflower stem waste) were evaluated as co-substrates for food waste. Their alkaline nature offers buffering capacity, enhancing pH stability and mitigating acidification during digestion. Anaerobic co-digestion experiments were conducted using food waste with banana peel (FWBG) and food waste with cruciferous vegetable, cauliflower stem waste (FWC) to improve alkalinity and overall reactor stability. Results showed that, pH in both FWC and FWBG was acidic due to the rapid breakdown of food waste, but stabilized to an optimal range with improved alkalinity on co-substrate addition. The cumulative biogas generation was significantly enhanced in the co-digestion reactors, by 30 % in FWC and 22 % in FWBG, compared to food waste (FW) alone. The volatile fatty acid (VFA) profile indicated the presence of acetic, propionic, butyric, and valeric acids in the FW, whereas only acetic acid was dominant in FWC, suggesting more efficient VFA conversion to methane. Kinetic studies revealed FWC had the highest biogas production rate, Rm = 800.24 mL/day, with a minimal lag phase, λ = 0.0071 days. Metagenomic analysis showed that co-digestion enriched methanogenic archaea (e.g., <em>Methanosarcinia</em>) and syntrophic bacteria (e.g., <em>Clostridia</em>, <em>Negativicutes</em>), enhancing microbial resilience. Scaling up this approach to 1 t per day could reduce annual CO₂ emissions by 1062–1854 kg. This study provides a practical pathway to transform food and vegetable waste into clean energy, contributing to SDG 7 (Affordable and Clean Energy) and SDG 12 (Responsible Consumption and Production) by integrating biogas production with agricultural residue utilization.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"91 ","pages":"Article 101921"},"PeriodicalIF":4.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145840809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
