Anaerobic Digestion
The Primary Product of Sprouter Energy is Green Biogas a renewable energy source achieved via Anaerobic Digestion (AD). Through this natural biochemical process, organic waste is processed into green biogas which can then be converted into green electricity, heat, green biomethane or used to generate other sustainable fuels such as green hydrogen. Anaerobic Digestion energy and its by-products are part of the circular economy.

Anaerobic Digestion (AD) as an energy process has a long history, first used by the Assyrian’s in the 10th century BC to heat bath water. AD is a natural process in which microorganisms break down organic materials. “Organic Materials” are referred to as any material coming from or made of plants or plant-based origins, or from animals including animal and human waste.
Some of the materials considered organic which can be process in a anaerobic digester are: animal manure, food scraps or waste, fats, oils and grease, industrial organic residuals and sewage sludge (biosolids). These materials are referred to as "feedstock". Anaerobic digestion happens within a closed heated environment referred to as a digester, free of oxygen to allow the microorganisms to breakdown and transform the feedstock.
Feedstocks are collected and processed at the AD site, then introduced into the digester to begin the fermentation process. Here, the mixture is up brought to a temperature of 35ºC-38ºC, continually agitated for period of 30 days in an environment absent of oxygen. Over this period of time the microorganism break down the organic materials creating a green biogas which consists mainly of methane (CH4) and carbon dioxide (CO2) with small amounts of water vapor (H2O) and a few other trace gases and digestate.
The feedstock used in the Sprouter Energy process comes from organic waste only. Some biogas processors use purpose grown crops with many biomass processors burning wood chips and wood pellets - these processes are only slightly less polluting than using fossil-fuels and are therefore designated grey- or black-biogas.
​
By using only organically natural feedstock, Sprouter Energy produces only green biogas which translates into all of our by-products certifiable green.
