Abstract
Nigeria faces persistent electricity shortages and increasing municipal solid waste generation, both of which negatively affect economic productivity, environmental sustainability, and urban livelihood. This study evaluates the feasibility of deploying waste-to-energy (WtE) systems as an integrated solution to simultaneously address energy deficits and waste management challenges in Nigeria. A documentary-based assessment was conducted using peer-reviewed literature, national policy documents, and industry reports published between 2015 and 2026. The study applied a multi-criteria readiness framework to classify Nigerian states into high, medium, and low-readiness deployment tiers based on waste generation volume, collection efficiency, and energy recovery potential. Findings reveal different readiness levels, the highest demonstrating recoverable energy potential exceeding 50 MW. A second tier of states shows moderate feasibility but depends on improvements in waste logistics, feedstock consistency, and infrastructure efficiency. Lower-tier states remain constrained by poor waste collection systems, weak infrastructure, and policy limitations. The study further highlights that successful WtE implementation requires integrated system design, emissions control, regulatory stability, and stakeholder coordination. It recommends a phased “flagship-first” deployment strategy through public-private partnerships, complemented by an “organics-first” approach that integrates anaerobic digestion and the informal waste sector for sustainable recovery.

Nigeria’s electricity sector continues to face major challenges due to aging infrastructure, which
increases operational costs and reduces overall efficiency. This study aimed to assess how
procurement practices influence sustainability within the Nigerian Electricity Regulatory
Commission (NERC), South-East, with a specific focus on the effect of green technology on
environmentally friendly products. Using a quantitative correlational design, 148 surveys were
distributed to staff across Anambra, Enugu, Ebonyi, and Imo states, of which 133 were completed
and used for analysis. Pearson correlation and descriptive statistics were employed to test the
hypotheses. The results revealed a very strong and statistically significant positive correlation
between green technology and eco-friendly products (r = .994, n = 132, p < .01), indicating that
advancements in green technology account for a large proportion of changes in environmental
product outcomes. Based on these findings, the study recommends that NERC strengthen
procurement policies by prioritizing vendors who provide certified green technologies and
environmentally sustainable materials.

Effective waste management is essential to attain the UN Sustainable Development Goals (SDGs), yet developing countries like India face significant challenges due to limited infrastructure, inadequate public awareness and rapid urbanisation. In Varanasi, over 1000 tons of municipal solid waste are generated daily, with only 600 tons processed at a single commercially functioning composting facility. Poor waste segregation reduces compost efficiency to 8%–10%, leaving large quantities in landfills and open dumpsites. This study highlights critical limitations in Varanasi's solid waste management, including inconsistent waste tracking and insufficient route optimisation, which hinder operational efficiency. Responses from 400 residents and expert insights reveal the city's SWM system operates at just 41% efficacy. Binomial logistic regression indicates that demographic factors and satisfaction levels account for 58.2%–88.8% of the variance in citizen satisfaction. A sustainable framework is proposed to enhance landfill diversion through waste reduction and improved processing, advancing Varanasi's zero‐waste and circular economy goals.
As the world strives to transition toward sustainable energy systems, Sustainable Development Goal (SDG) 7 emphasizes universal access to clean, reliable, and affordable energy sources. Biogas technology provides a viable solution by converting organic waste into renewable energy, thus promoting both environmental sustainability and energy efficiency. This aligns with the aspirations of SDG 12, which emphasizes responsible consumption and production through effective waste management. The study sought to assess the intersection between household economics and community energy needs. The study employed a cross-sectional survey research design to collect data from a sample of 133 participants. Data was collected using a semi-structured interview guide. The findings reveal that 78% of respondents were aware of biodigester technology, while 72% had a positive perception of its effectiveness in energy provision and waste management, respectively. Approximately 65% of users reported operational biodigesters that produced sufficient biogas for daily cooking, with 70% confirming a reduction in dependence on firewood. Socially, 82% cited improved household health due to reduced smoke exposure, and 68% highlighted enhanced sanitation and odour control. Economically, 59% of respondents noted cost savings on fuel, while 43% earned a modest income from the sale of bio-slurry. The study found that 34% of households expressed confidence in their long-term financial sustainability, and this finding (χ² = 18.42, p < 0.05) confirmed a significant relationship between community awareness and technology adoption. The study recommends enhanced awareness and support for biogas use expansion among the residents owing to its socioeconomic value.

This study develops a framework for assessing anaerobic digestion as an organic waste treatment technology in Indonesia by evaluating feedstock availability, technological feasibility, policy context, market dynamics and implementation barriers. Using a convergent parallel mixed methods approach, the research integrates quantitative analysis of national and provincial waste generation data with qualitative policy and market assessments to examine the suitability of anaerobic digestion within Indonesia’s waste management context and sustainable development objectives. The study explores anaerobic digestion as a waste treatment solution that delivers environmental and energy co-benefits, including biogas production and greenhouse gas emissions reduction, while prioritizing landfill diversion and waste stabilization. Analysis of regional waste data indicates that Indonesia faces a significant organic waste management challenge with approximately 13.03 million tonnes of organic waste requiring treatment annually. Anaerobic digestion implementation across three phases were reviewed, complementing conceptual scenarios using regional data to demonstrate how anaerobic digestion can tackle Indonesia’s waste crisis while providing a dual benefit of biogas generation. Overall, the findings indicate that regulatory enforcement gaps, feedstock quality constraints, limited waste segregation, and underdeveloped off-taker markets remain critical barriers to anaerobic digestion deployment. In response, the study proposes a strategic implementation framework spanning five key dimensions surrounding regulatory strengthening, technical standards development, market infrastructure enhancement, capacity building, and pilot scale deployment to support the context-appropriate and scalable application of anaerobic digestion as a waste treatment solution in Indonesia.
Biogas energy has emerged as a sustainable, renewable energy source that can help tackle global issues like energy security, climate change, waste management, and the development of a circular economy. It is produced through the anaerobic digestion of organic materials such as agricultural leftovers, livestock manure, municipal solid waste, food waste, and wastewater sludge. Biogas presents significant opportunities to reduce greenhouse gas emissions while generating renewable electricity, heat, and biomethane. Despite gaining more attention from researchers, the existing studies are often fragmented. They usually focus on individual technical, economic, environmental, or social aspects without properly looking at how these areas are connected. This study carries aims to bring together current knowledge on biogas energy development and to clarify the factors that influence its successful implementation. The study integrates peer-reviewed studies published from 2015 to 2026, gathered from major scholarly peer-reviewed journal articles. The selected literature is analyzed using a structured systematic review method to pinpoint key research themes, drivers for implementation, technological innovations, barriers, and outcomes related to sustainability in biogas energy systems. The findings categorize the main factors affecting biogas development into five major areas: availability of feedstock, anaerobic digestion technology, recovery and use of resources, policy and financial support, and applications of end-use energy. Additionally, the review assesses the numerous benefits and barriers from technical, economic, environmental, and social viewpoints, emphasizing their connected relationships within sustainable energy systems. The study adds to the growing literature on renewable energy by putting forward a combined conceptual framework that illustrates the interactions among these four sustainability dimensions in biogas energy development. The framework shows how technological improvements boost environmental performance, economic feasibility, and social acceptance while also recognizing the challenges tied to investment costs, operational complexity, policy uncertainty, and engagement with stakeholders. Lastly, the review points out new research directions and offers practical advice for policymakers, researchers, industry professionals, and investors who want to speed up the adoption of biogas technologies and aid the global shift toward a low-carbon circular economy.
