Probably most people know that when organic matter such as kitchen waste rots, it can produce flammable methane. As a source of free energy it’s attractive, but making a biogas plant sounds difficult, doesn’t it? Along comes [My engines] with a well-thought-out biogas plant that seems within the reach of most of us.

It’s based around a set of plastic barrels and plastic waste pipe, and he shows us the arrangement of feed pipe and residue pipe to ensure a flow through the system. The gas produced has CO2 and H2s as undesirable by-products, both of which can be removed with some surprisingly straightforward chemistry. The home-made gas holder meanwhile comes courtesy of a pair of plastic drums one inside the other.

Perhaps the greatest surprise is that the whole thing can produce a reasonable supply of gas from as little as 2 KG of organic kitchen waste daily. We can see that this is a set-up for someone with the space and also the ability to handle methane safely, but you have to admit from watching the video below, that it’s an attractive idea. Who knows, if the world faces environmental collapse, you might just need it.

Horeb Energy and Veolia Are Mining Bitcoin At 2.5¢/kWh With Colombian Landfil Biogas

Colombian Bitcoin and crypto mining company Horeb Energy reveals 2.5 cents per kWh of green biogas energy in the North Santander region of the Latin American country. The company has achieved energy prices 50% lower than the North American average of 3.5 to 6 cents per kwh for Bitcoin mining operations, through a strategic alliance with multinational energy company Veolia. 

Authorized in 1853 by Napoleon III to help build out public water works infrastructure in France, Veolia is a global leader in environmental services focused on water, waste, and energy solutions. Today in Norte de Santander, Colombia, the company operates critical facilities dedicated to biogas valorization and solid waste management — a common problem in Colombia and Latin America in general, known for massive landfills.  Veloia also operates the “Centro Inteligente de Gestión Ecológica” – CIGE Guayabal landfill, a pioneer in biogas systems development in the region. 

Horeb Energy — the Bitcoin mining arm of the operation — specializes in technological solutions for biogas treatment and renewable energy production from waste. “It’s collaboration with Veolia in this pilot project sets a milestone for new sustainable business models in the global cryptocurrency mining sector,” the company said in a press release, adding that “The project aims to reduce the region’s carbon footprint significantly and demonstrates Veolia’s strong commitment to accelerating the ecological transformation of local territories.”

Through this pilot project, biogas generated at the CIGE Guayabal landfill by Veolia is transformed into electricity to supply a secure, standalone data center dedicated to cryptocurrency mining. Horeb Energy oversees advanced biogas filtration and energy conversion processes, and the Bitcoin mining dimension, which unlocks new economic models for energy infrastructure development in the region.

One year after its launch, the program boasts tangible results with the production of “nearly 1,000 kWh of 100% renewable energy”, powering an entirely off-grid Bitcoin container and mining system. This unique approach in the Colombian market provides an alternative use for methane gas — a byproduct of waste decomposition that poses environmental challenges for landfills.

Humberto Posada Cifuentes, General Manager of Veolia in Norte de Santander, said in a press release that this pilot “demonstrates that with innovation and strong local leadership, we can turn waste into value and contribute meaningfully to the clean energy transition.”

Arley Lozano, Operations Manager of Horeb Energy, told Bitcoin Magazine that they had achieved 2.5 cents a kWh in green energy, adding that “we are proud that this project has been developed by local talent in partnership with Veolia. Our goal is to replicate this model in other municipalities across Colombia and throughout Latin America.”
