This case study by RMI evaluates the economic and environmental impact of an anaerobic digestion (AD) facility at the Oko Oba Abattoir in Lagos, Nigeria. The analysis compares a business-as-usual (BAU) scenario with scaling options to replace charcoal fuel and diversify biogas use, concluding that while the project is economically viable, high upfront capital costs remain a significant barrier to private investment.

A research paper by the Stockholm Environment Institute evaluating the sustainability and economic feasibility of ecotechnologies for recovering carbon and nutrients in Sweden, Poland, and Finland using a bottom-up cost-benefit analysis.

This case study examines how Elgin Fruit Juice in South Africa addressed seasonal energy demand imbalances by transitioning from a planned grid-feed electricity model to using biogas as a coal replacement in steam boilers.

This research paper review examines the effectiveness of ecotechnologies, specifically struvite precipitation and ammonia stripping, for recovering nitrogen and phosphorus from the liquid phase of anaerobic digestate to provide plant nutrients and renewable energy while reducing environmental waste impact.

This report details a multi-criteria analysis (MCA) conducted by the BONUS RETURN project to evaluate the sustainability of various eco-technologies for recovering nutrients and carbon from waste. The study focuses on three catchment areas: Vantaanjoki in Finland, Fyrisån in Sweden, and Słupia in Poland. By engaging local stakeholders to weight sustainability criteria, the report compares baseline management systems against alternatives such as anaerobic digestion, pyrolysis, and source-separation of wastewater.

This fact sheet from the Environmental and Energy Study Institute describes the process and benefits of using anaerobic digestion to convert organic waste—including livestock manure, food waste, and wastewater—into biogas. It outlines the potential for biogas to provide baseload power, reduce methane emissions, and create jobs in the United States, while detailing the regulatory frameworks and funding programs that support the industry.

This report by GreenCape identifies business opportunities for adding value to livestock waste streams, specifically manure and abattoir waste, within the Western Cape of South Africa. It details the regional distribution of waste sources, current disposal methods, and the regulatory and technical barriers to implementing value-addition technologies like anaerobic digestion and composting.

This case study describes a circular economy collaboration facilitated by the Western Cape Industrial Symbiosis Programme (WISP) between Cape Town Market, Elgin Fruit Juice, and Ywaste. The partnership diverts organic food waste from landfills to produce electricity via anaerobic digestion and creates compost through a reverse-logistics loop.
