Solar Cities IBC Floating Gas Holder for Biogas System for Refugee Camps

The details of Biogas Holders are explained here.

The Solar CITIES IBC is a Floating Gas Holder for Biogas system for refugee camps.

Do you cook on wood or with gas or electricity? You don’t have to! This film shows you how to make a simple biogas digester and produce biogas from kitchen scraps, other food waste, even animal manure. You can then store the gas in simple inflatable bags and connect them up to your stove.

You might think biogas is for ‘developing’ countries but it should be the free and easy to make and manage alternative to fossil fuels as well as wood. IT is as applicable in a New York basement as it is in Africa.

To get the gas and the effluent out you can use garden hoses or clear plastic tubing. No big deal there; this stuff isn’t under much pressure at all.

The gas comes right out the top so you don’t need any pipe there. The fertiliser comes out of the “dead zone” in the middle of the tank (fats and oils, which contain lots of energy, tend to float, and proteins and carbs tend to sink, so the top and bottom of the tank are biologically active) so you want that one inch pipe going down to the halfway mark. The feeding pipe should reach to about 10 or 15 cm above the bottom of the tank to leave room for the rocks and active sludge without the food getting blocked on its way down and into the tank.

Feedback About Solar CITIES IBC Blueprint

I have a small biogas power plant that I’m feeding with organic waste and making electricity out of it. It’s pretty nice and it saves my energy bills up to 30%. If you’re thinking of DIY your own backyard bio-plant and especially if you’re going to produce electricity, there’s no better blueprint online than bio-powerplant. You will need to have a two small barrels. One (digester) is where the animal, human and other organic wastes are introduced, usually as a slurry with water, to break down anaerobically. The other one (storage container) is used to hold the gas produced, from which it is piped for burning as a fuel. When the digester is emptied, the spent effluent is dried for later reuse as a fertiliser. Most of the things you need you probably already have somewhere around your house or you can get for very little money.

Hi there, I am Sahas chitlange, aging from India. here is my homemade cheap and easy to build mini Biogas plant. It burns for approx. mins on a bunsen.

I just wanna ask something about the fertilizer outlet pipe, isn’t it using a 3inch pipe? because I’m confused with the 2inch Tee and a 2 inch pipe. Any clarification is appreciated. Thanks.

Hello, I am currently starting a nonprofit focused on providing a sustainable way of life. This is one of the exact pieces that I need and you seem to be one of the only people that hinted at a heat extraction by water running through tubes! Feel free to contact me at 303-246-1776 and I would love to see if we could work together!

The Solar Cities IBC biodigester is a very simple design for a home-scale biodigester. This design of digester is very cheap and easy to build, and ideal for domestic use. It can be installed in a basement, greenhouse, or outside the house, and it can provide hours of renewable, flammable gas per day, using just the organic waste produced by the household. It also produces a high quality liquid fertilizer that can be fed to hydroponic vegetables or used to build compost.

Food scraps and organic, non-woody biomass are ground into a fine slurry an mixed with water. This mixture is added to the biodigester through a feed tube. Inside the digester, a colony of methanogenic bacteria convert the complex molecules into methane gas, which is chemically similar to natural gas. The methane is stored in a bag or container, and the water that flows out the other end contains dissolved nutrients ideal for growing plants.

These organisms break down organic waste in the absense of oxygen, and produce a high-quality flammible gas, called Biogas, composed primarily of CO2 and Methane (CH4) and an effluent that can be used as a high quality liquid fertilizer.

The Solar Cities IBC biodigester is fully documented and open-source and has been tested and proven in many countries. The IBC tote that contains the culture is a standard international shipping unit for bulk liquids and are available for cheap or free all over the world.

Much like The Urban Farming Guys tutorial on DIY biogas, the Solar CITIES folks are using an Intermediate Bulk Container (IBC), which can often be found used from many food processors and other industrial operations. Basically they then just have to measure and cut three different pipes—one for feeding, one for the gas outlet, and one for displaced liquid fertilizer—insert them into the tank at the appropriate spots through a universal seal, and then plumb them in and get rolling.

Yes, that’s an abridged version of how this is done. But the whole video takes eight minutes, so you can see for yourself how simple it looks. Solar CITIES (or possibly Solar C³ities—both spellings are used on their website), by the way, is an international non-profit dedicated to creating “an open-source virtual Hackspace for Biogas Innoventors and Practitioners.” Which seems like a worthwhile goal. Now I just need to convince my wife to fill the basement with a big tank of sludge and gas…

Solar CITIES IBC Conclusion

You can be generating biogas at home to use for space and water heating, lighting, and cooking. Paul Scheckel guides you through the basics here.

The Vietnam Household Biogas Project is installing biogas systems across Vietnam which use waste from household cattle and pigs to create electricity for the home. This one-of-a-kind project is spreading renewable energy to households across Vietnam.via
