Is Anaerobic Digestion Right for Your Farm?
Have you ever heard of biogas? Biogas is produced after organic materials, including the plant and animal products, are broken down by bacteria. In an oxygen-free environment, there is a process called anaerobic digestion. An estimated 1.3 billion tonnes of food is wasted each year globally, according to the Food and Agriculture Organization (FAO) of the United Nations. These wastes pose a significant risk to our environment and public health, when not properly managed. Chemicals and pathogens that are present in wastes can contaminate groundwaters and soils that can also infect drinking waters.
To reduce greenhouse gas emissions and the risk of pollution to waterways, REURASIA Energy Solutions is providing an effective way to remove waste and use it to produce biogas as renewable energy and a source that can help livestock businesses. See illustration below:

Biogas systems create a sustainable energy solution with the use of anaerobic digestion. This means that those organic waste will be recycled; turning them into biogas, which contains both energy and valuable soil products for farmlands. Compared to the traditional manure system, anaerobic digestion for biogas production is known as an effective way of managing waste materials. It improves the sustainability of the farm’s daily operations by conserving resources and cutting methane emissions, both of which combat climate change.
In some parts of the world, anaerobic digestion already occurs in many landfills, and some in livestock farms manure and management systems. According to the EESI (Environmental and Energy Study Institute) report, biogas contains roughly 50-70% of methane, 30-40 % of carbon dioxide, and trace amounts of other gases. The liquid and solid digested material, called “digestate”, is frequently used as a soil amendment(October 2017).
Below is the increasing number of biogas plants.

Revenue Growth on Livestock Businesses.
Biogas plants create additional profit for farmers and in the livestock sector. Recycling with REURASIA’s biogas provides a solution to energy crisis by adding value and energy to farm waste and boosting livestock income. Biogas plants offer exceptional benefits that can help livestock business and can simplify the utilization of farm waste streams, adding value to it that will give one such opportunity to boost efficiency. Developing a more sustainable and renewable energy solution can diversify a farmer’s income. Diverting that waste to value would turn a cost into an opportunity, generating revenue from energy production. With the newly produced biogas plants will help farmers to be economically and environmentally responsible. Accordingly, these can also be produced commercially and sold worldwide, and at the same time, farmers will have a social function as energy providers and waste treatment operators.
Digestate, the material remaining after the anaerobic digestion process, can be used or sold as fertilizer, reducing the need for chemical fertilizers. Compared to traditional manure, this digested substrate is safer to use, making it a more accessible form for agricultural land. Digestate also can provide additional revenue when sold as livestock bedding or soil amendments. This would also protect the local waterways as it reduces the nutrient run-off and those destroying pathogens.
Business Expansion and Farm Growth
In today’s market demand, affordable food supply is needed to sustain the growing population every year. These biogas plants- an energy crisis solution to meet the increasing demand for food and remain viable in the market competition. Manure digesters on livestock farms can result in a much safer environment and agricultural land.
Livestock farm business became more physically closer to new facility developments than before. With the adverse effects of large-scale feeding operation, electricity and energy sources matter the most. Biogas plants-a renewable energy solution provides energy independence for farms. Manure digester systems can meet on-farm energy needs. It can also be used to generate electricity for lighting, heat and on-site energy for cooling milk, and fuels. It allows farmers to operate efficiently and helps them reduce expenses on utilities.
Our On-Farm Solution
Biogas-a renewable source of energy turns the cost of waste management into a revenue opportunity. For energy crisis solutions, with the tons of food waste per day, anaerobic digestion can generate enough energy to power many homes each year. Converting your waste into electricity, heat, or vehicle fuel can sustain quality and increase local chances. With the great benefits of biogas plants, farmers can perfectly integrate it into conventional and organic farming, where digestate replaces chemical fertilizers, produced with consumption of large amounts of energy.
