About Us - GEK Gasifier. Biodigester. 18 MJ of energy per day No operation cost No smoke Safe to use With biogas level indicator Manure for agriculture/gardens DIY Renewables have their 1st prototype functional in Lagos Nigeria.
It is simple to install and low maintanenance. The biodigester consists of a 300 gallon PVC tank with outlet for the biogas. It can help reduce or even terminate the need for cooking gas. Anaerobic fermentation of organic waste (kitchen, agricultural, and many other kids of waste) inside of the tank can produce enough biogas for 4-5 people's cooking needs per day, as well as manure for your garden once per month.
For Hotels/Farms it serves a dual purpose: Waste disposal Fuel generation Additionally, through pressure build-up, the biogas generator is able to display the amount of biogas currently stored, giving the user a clear indication of available volume. The diagram to the right demonstrates how a small-utility biogas generator works. D.I.Y. The Methane Midden - Heat / Energy with Compost by Robert Frost. I want to leave the world a better place for our children.
I want to use less fossil fuels. And I want to find ways to grow more food in small spaces like suburban backyards. And I want to tell the world about it so everyone can do it; it takes a village! Last winter I discovered Jean Pain, a revolutionary French activist in the 1970's who designed a system that made methane gas and heated water using nothing but composting. His piles were epic- over 50 tons and stayed hot for over 18 months. I want to see if a slightly smaller scale pile is possible and can be replicated in today's American Suburbs. I want to install a compost hot water system - very similar to a solar hot water system- where the heat from a large compost pile is transferred to the water in our domestic hot water system to significantly reduce our natural gas use.

The Complete Biogas Handbook: How to build an ARTI-style biogas digester. ARTI is the Appropriate Rural Technology Institute, established by Dr.
Anand Karve in Maharashtra, India (which is 400 km inland from Mumbai /Bombay). His digester design is really simplicity itself: Take a water tank and cut the top off. Take a smaller water tank and put it upside down inside the first tank. Add a modest bit of plumbing, and there it is. (The unit behind Dr. “In the old unit some gas was lost…” In 2006, ARTI won an Ashden Award for this design, which is topologically identical to a design proposed at least as long ago as 1984, when the second FAO title mentioned on the page about 55-gallon digesters (“Biogas: What it is…”) was published. You have already built one or more biogas units like the one described in… “Biogas: what it how it is made; how to use it”…. However, the new unit is closed. Of course, all digesters have advantages and disadvantages, and the ARTI digester suffers from both of these problems (loss of biogas, and, depending on what it is fed, odor).
