India Nammakal Biogas
What is Biogas?
Biogas is produced after plant and animal products are broken down by bacteria in an oxygen-free environment, a process called “anaerobic digestion”.
Biogas systems use anaerobic digestion to recycle these organic materials, turning them into biogas, which contains both energy and valuable soil products, used for instance in agriculture.
That process already occurs in nature, landfills, and some livestock manure management systems, but thanks to anaerobic digesters, it can be contained, controlled, and optimized.
About this Project
Background
With a rapidly expanding economy and population, India is in dire need of a reliable and sustainable energy supply to facilitate economic growth and mitigate escalating pollution levels. A major concern is in the Nammakal district of Tamil Nadu, where 60-70% of the state's total chicken and egg supply is produced. The traditional practice of open storage of chicken litter leads to severe environmental and hygienic issues, alongside the release of harmful methane emissions.
Project Outcome
The Nammakal Waste to Energy Project, a pioneering initiative in India, addresses these issues. This project converts up to 120,000 tons of chicken litter and other organic residues from starch and sugar industries per year into renewable electricity. The generated power is then fed into the southern electricity grid. By deriving renewable energy exclusively from biomass waste, the project avoids any competition with food production, thus providing an innovative solution to a multifaceted problem.
Aside from reducing climate impacts, up to 10,000 tons/year of high quality solid organic fertilizer are being produced, supporting local and regional smallholders in implementing sustainable agricultural practices. This in turn increases their crop yields and improves their livelihoods, while respecting the environment.
