Why Use Our Biogas Technology

Biogas is a renewable, as well as a clean, source of energy. Gas generated through bio digestion is non-polluting; it actually reduces the greenhouse effect. No combustion takes place in the process, meaning there is zero emission of greenhouse gasses to the atmosphere; therefore, using landfill gas as a form of energy production is actually a great way to combat global warming. Unsurprisingly, concern for the environment is a major reason why the use of biogas has become more widespread. The biogas plants lower methane emissions by capturing this harmful gas and using it as fuel. Biogas unlike other types of renewable energies, the process is natural, not requiring energy for the generation process. In addition, the raw materials used in the production of biogas are renewable, as trees and crops will continue to grow. Manure, food scraps, and crop residue are raw materials that will always be available, which makes it a highly sustainable option.

Overflowing landfills don’t only spread foul smells- they also allow toxic liquids to drain into underground water sources. Consequently, yet another advantage of biogas is that biogas generation may improve water quality. Moreover, anaerobic digestion deactivates pathogens and parasites; thus, it’s also quite effective in reducing the incidence of waterborne diseases. Similarly, waste collection and management, significantly improves in areas with biogas plants. This in return leads to improvements in the environment, sanitation and hygiene.

The technology used to produce biogas is quite cheap. It is easy to set up and needs little investment when on a small scale. Small bio digesters can be used right at home, utilizing kitchen waste and animal manure. A household system pays for itself after a while, and the materials used for generation are absolutely free.

The gas manifested can be used directly for cooking and generation of electricity. This is what allows the cost of biogas production to be relatively low.

Biogas generators save women and children from the daunting task of firewood collection. As a result, more time is left over for cooking and clean. More importantly, cooking on a gas stove instead of over an open fire prevents the family from being exposed to smoke in the kitchen. This helps prevent deadly respiratory diseases. Sadly, quite a large number of people die prematurely from illness attributable to the household air pollution caused by the inefficient use of solid fuels for cooking.

A biogas plant is not only as supplier of energy. The digested substrate usually referred to as Digestate or Bio-Slurry is valuable soil fertilizer, rich in nitrogen, phosphorus, potassium and micronutrients, which can be applied on soils with the usual equipment for application of liquid manure. The Digestate/Bio-slurry is an improved organic fertilizer which also reduces burning effect on plants, Improves plant health, improves flowing properties, Reduces germination ability of weed seeds and reduces smell of the biomass while increasing the farm yields. The Bio-slurry is highly nutritious, affordable, enhances water retention, adds humus to soil, is safer to handle and effective insect repellent.

Production of feedstock in combination with operation of biogas plants makes biogas technologies economically attractive for farmers and provides them with additional income. The farmers also get a new and important social function as energy providers and waste treatment operators.

Various types of feedstock can be used for the production of biogas: they range from animal manure and slurries, organic wastes from dairy production, food industries and agro industries, waste water sludge, organic wastes from households and from catering business.

Storage and application of liquid manure, animal dung and many organic wastes are sources of persistent, unpleasant odours and attract flies. Anaerobic digestion reduces these odours by up to 80%. Bio-Slurry is almost odourless and the remaining ammonia odours disappear shortly after application as fertilizer.

Application of the bio-slurry as fertilizer, compared to application of untreated manure and slurries, improves veterinary safety. Depending on the type of feedstock involved, sanitation can be provided by the anaerobic digestion itself, through a minimum guaranteed retention time of the substrate time in the digester. The aim of sanitation is to inactivate pathogens, weed seeds and other biological hazards and to prevent diseases transmission through Digestate/bio- slurry application.
