Phnom Penh: Experts are encouraging farmers with livestock to consider installing biogas plants, citing their potential benefits for health, livelihoods, and the environment.

Biogas plants convert manure into natural fertilizer and fuel. They are typically constructed from brick or resin and range in size from 4 to 15 cubic meters.

"A biogas plant is like a family treasure," says Mr. Koam Bunthoeun, a resident of Pursat province who has been using a biogas system for over a year. "It provides excellent natural fertilizer, reduces healthcare costs, and contributes to climate change mitigation."

Mr. Bunthoeun's 4-cubic meter brick biogas plant cost approximately $400 and requires daily input of about 20 kg of cow dung. He highlights the numerous benefits he has experienced, including:

Reduced healthcare costs: Biogas eliminates the need for firewood for cooking, reducing exposure to harmful smoke and improving respiratory health.

Cost-effective fertilizer: The natural fertilizer produced by the biogas plant is free, odorless, and suitable for various crops, vegetables, and fruit trees.

Environmental benefits: Biogas technology contributes to reducing greenhouse gas emissions and mitigating climate change.

Mr. Kim Savoeun, Deputy Director General of the Department of Animal Health and Animal Production, and Director of the National Biodigester Program, explains that biogas plants come in two types: brick and resin. Brick plants have a longer lifespan (up to seven years) while resin plants are more readily available in various sizes.

Another farmer, Mr. Kong Srei, who raises 25 cows, utilizes a 10-cubic meter brick biogas tank. He emphasizes the effectiveness of the bio-fertilizer on crops and highlights its role in animal disease prevention.

"Biogas is a form of waste management that helps us control animal diseases like yachinosis," Mr. Savoeun adds.

The National Biodigester Program, established in 2004-2005, offers support and resources to farmers interested in installing biogas plants. The program is currently implemented in 16 provinces and aims to expand to nine additional regions.

"Biogas technology offers a win-win situation for farmers and the environment," Mr. Savoeun concludes. "We encourage all farmers with livestock to explore this valuable resource and contribute to a healthier and more sustainable future."
