The Biogas Solution

Turning manure to profit.

The Future of Agricultural waste Recycling’

Never heard of anaerobic digestion?

That’s okay, in Adventure Farm, it works like this; We pool manure into an oxygen free enclosure. Over time, Bacteria convert the manure from solid waste into liquid waste, which produces methane gas. The methane is separated out, collected and used to cook.

But, it doesn’t stop there. The reason these biogas systems are called ‘closed-looped' systems is because the liquid that remains in the digested is then used to fertilize farmland. This land grows crops which are then fed to the animals, who produce manure that is used in the digester. The fiber that is left after digestion can be used for compost fiber for cow bedding, potting soil or even cardboard .Since everything is recycled, the nutrients from the food will remain in this liquid and be back to the soil.


What is a biodigester?

Anaerobic digesters produce biogas much like the human digestion system. When biodigesters are fed organic material -food waste, agriculture residues, and animal or human manure. It is decomposer by microorganisms in the absence of oxygen and turned into biogas, which can then used for heating, cooking, transportation and other needs.


Which gases does biogas contain?

Biogas consists mainly of methane and carbon dioxide. It can also include small amounts if hydrogen, sulphide, siloxanes and some moisture. The relative quantities of these vary depending on the type of waste involved in the production of the resulting biogas.


The Need for Biogas

With little to no processing, biogas can be burned on-site to heat buildings and power broilers are even the digester itself. Biogas can be used for combined heat and power operations, or biogas can simply be turned into electricity using a combustion engine, fuel cell or gas turbine, with the resulting electricity being used on site or sold on the electric good.

Digestate is the nutrient-rich solid or liquid material remaining after the digestion process; it contains all the recycled nutrients that we’re present in the original organic material but in a form more readily available for plants and soil building.

The composition and nutrient content of the digestate will depend on the feedstock added to the digester. Liquid digestate can be easily spray -applied to farms as fertilizer, reducing the need to purchase synthetic fertilizers. Solid digestate can be used as livestock bedding or completed with minimal processing.


Biogas made from organic materials-including food and agricultural waste, and animal or human manure-is a renewable, sustainable, affordable and inclusive energy alternative becoming increasingly available to households, farms, municipalities and nations”
