As the global community accelerates toward net-zero targets, one technology stands out for its ability to tackle two pressing challenges simultaneously: waste management and clean energy generation.
Ikechukwu Offie, discusses the importance of Anaerobic Digestion (AD), the process behind biogas production, has proven transformative in developed nations. Yet, as highlighted in a recent comprehensive review by Ikechukwu Offie and colleagues, its adoption in developing countries remains uneven and, in some cases, nonexistent.
Why Biogas Matters
Biogas technology converts organic waste into renewable energy while producing nutrient-rich digestate for agriculture. This dual benefit supports a circular economy, reduces greenhouse gas emissions, and mitigates climate change impacts. In fact, replacing fossil fuels with biogas can cut emissions by up to 80%, while diverting waste from landfills prevents methane release—a major climate culprit.
The Global Picture
Between 2015 and 2023, Asia led the charge, with China producing a staggering 1,490 MW of biogas energy by 2023. Thailand, Indonesia, and Malaysia also made significant strides. Latin America followed, with Brazil emerging as a regional leader. However, Africa, the Middle East, and parts of Eurasia lagged behind. Shockingly, countries like Nigeria, Ghana, Mali, Sri Lanka, and Palestine reported zero biogas energy generation during the study period.
What’s Holding Us Back?
The barriers are multifaceted:
- Technical: Poor infrastructure, lack of skilled operators, and process instability.
- Economic: High capital costs and inadequate R&D funding.
- Policy: Outdated environmental regulations and weak enforcement.
- Social: Low awareness and cultural stigmas around biogas use.
- Environmental: Risks of leakage and odor issues if systems are poorly managed.
Opportunities for Change
The review recommends integrating AI and IoT technologies into AD systems to optimize performance and detect leaks. It also calls for:
- Stronger policy frameworks and incentives.
- Technical training for operators.
- Partnerships with developed nations for knowledge transfer.
- Incorporating AD concepts into engineering curricula.
Why EIA Members Should Care
For our industry, biogas represents a triple win—environmental stewardship, economic opportunity, and social impact. As governments and businesses seek scalable solutions for climate resilience, AD technology offers a proven pathway. EIA members can lead by:
- Advocating for supportive policies.
- Investing in pilot projects.
- Sharing best practices across borders.

When people ask what Farmwood does, the easy answer is ventilation, air quality and mechanical and electrical services. But that’s just the surface. What we actually do is make buildings safer, healthier, and compliant for the people who live, work, and learn inside them.
Air quality is a critical issue, hitting deprived communities the hardest. These areas often find themselves near industrial zones and busy roads, lacking the green infrastructure that could naturally clean the air. This unfortunate reality places a disproportionate health burden on residents already facing socioeconomic challenges.
The collapse of the UN Global Plastics Treaty negotiations in Geneva marks a critical failure in the global fight against plastic pollution. As Co-Chair of the Environmental Industries Association (EIA) Climate Change Group, I am deeply concerned by the lack of progress and the implications this has for the UK’s environmental leadership and industrial innovation. In my previous role as Environment Minister I was on the front line of negotiations back in 2024 and the UK was a key player in a group of over 80 countries pushing for high ambition for this treaty which included setting targets to cap production with the ultimate aim of reducing harm form plastic pollution by 2040 . However, despite extra time being given for the negotiations, a year on, the talks are in tatters and the consequences are serious.
London, 30 October 2024 –The Environmental Industries Association (EIA) has expressed significant concerns regarding the Labour budget announcement by the Chancellor Rachel Reeves. EIA Chairman Peter Atchison specifically highlighted the budget’s shortcomings in addressing critical environmental issues such as climate change, air quality, brownfield remediation and supporting the wider delivery arm of the UK green industries sector.
