EXPLAIN YOUR IDEA

The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids. Acetogenic bacteria then convert these resulting organic acids into acetic acid, along with additional ammonia, hydrogen, and carbon dioxide. Finally, methanogens convert these products to methane and carbon dioxide.

WHO BENEFITS?

1. The farmers. They get access to electricity and heat, and they can earn money with it. 2. The farmer's community, that can start running hospitals and schools with the electricity 3. Everyone, because it helps to fight climate change

WHERE WILL YOUR IDEA BE IMPLEMENTED?

The idea could be implemented almost anywhere, but I would start with Burma, since some countries in Asia do already have experience with anaerobic manure digestion for animal agriculture.

ARE YOU IMPLEMENTING IN AN ELIGIBLE COUNTRY?

  • This idea is meant to inspire - I hope someone else takes it on!

EXPERTISE IN SECTOR

  • I do not have experience working in a sector related to my idea

EXPERIENCE IN IMPLEMENTATION COUNTRY(IES)

  • Not yet.

Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen. One of the end products is biogas, which is combusted to generate electricity and heat, or can be processed into renewable natural gas and transportation fuels. A range of anaerobic digestion technologies are converting livestock manure, municipal wastewater solids, food waste, high strength industrial wastewater and residuals, fats, oils and grease (FOG), and various other organic waste streams into biogas, 24 hours a day, 7 days a week. Separated digested solids can be composted, utilized for dairy bedding, directly applied to cropland or converted into other products. Nutrients in the liquid stream are used in agriculture as fertilizer.

Thanks for the contribution Christopher! JOEL SSIMBWA MUKASA also submitted an idea about converting waste into biogas: Bio-gas Waste to Energy Extracting Technologies for Uganda and East African communities. Perhaps you might like to reach out and collaborate.

Also, we've added one more question, "Tell us more about you," to your idea form. To update your post, hit Edit Contribution at the top of your idea. Then scroll down to find the "Tell us more about you entry field" at the bottom of this post. This will help us understand a bit more about you and your organization.
