Mini Biogas Plant Project

A limited quantity of biogas is extracted from the processing of agricultural sewage, subsequently integrated into a compact biogas initiative. This biogas serves multiple purposes within the farm, either by generating electricity for internal consumption or acting as a primary heat source. Harnessing organic waste to produce biogas not only aids in waste management but also contributes to sustainable energy practices. Through this small-scale project, farms can mitigate their carbon footprint while concurrently enhancing their energy autonomy and operational efficiency. This integrated approach underscores the potential for eco-friendly solutions in agricultural settings, fostering both environmental and economic benefits.

YHR Small Biogas Projects

Hubei Project

The Wuhan Project is a waste management endeavor aimed at COFCO's pig breeding base in Wuhan City. It employs anaerobic fermentation to produce eco-friendly biogas from the base's manure. With a 2MW capacity and daily output of 20,000m³, the biogas powers electricity generation.

Guangdong Project (1000m³/d, 650m³/d, 270m³/d, 22300m³/d, 800m³/d)

Because of the anaerobic process, a small amount of biogas will be produced during the treatment of wastewater from cattle and poultry. By collecting and using this portion of the biogas, livestock farms can use it as a small source of heat and electricity.

Benefits of Small Biogas Plants

Compact biogas plants offer a range of benefits, making them an attractive solution for sustainable waste management and energy production. Firstly, these plants effectively manage organic waste, including agricultural residues and animal manure, thereby reducing environmental pollution and improving sanitation. Secondly, they provide a renewable energy source in the form of biogas, which can be utilized for cooking, heating, electricity generation, and even as vehicle fuel, thereby reducing reliance on fossil fuels and lowering energy costs. Additionally, the solid digestate produced during biogas production serves as a nutrient-rich organic fertilizer, enhancing soil health and fertility. Furthermore, by capturing methane emissions from organic waste, biogas plant small size contribute to greenhouse gas reduction and climate change mitigation efforts. Overall, small bio gas plant offer a sustainable and cost-effective solution that promotes environmental stewardship, energy independence, and economic opportunities.

Feedstock Collection

Collect organic waste materials such as kitchen food scraps, animal manure, agricultural residues (like straw or corn stalks), or sewage sludge. Then ensure the materials are free from non-biodegradable items like plastic or metal.

Digester Setup

Construct a digester, which can be a simple container or tank made of materials like concrete, plastic, or metal. Ensure the digester is airtight to create anaerobic (without oxygen) conditions necessary for the digestion process. Size the digester appropriately based on the amount of feedstock you have and the expected biogas production.

Feedstock Loading

Load the organic waste materials into the digester. Aim for a balanced mix of carbon-rich and nitrogen-rich materials for optimal biogas production. Consider chopping or shredding larger materials to increase surface area and accelerate decomposition.

Anaerobic Digestion

Allow the microorganisms naturally present in the organic waste (or inoculate the digester with a starter culture) to break down the materials in the absence of oxygen. Microorganisms will produce biogas (mainly methane and carbon dioxide) as they digest the organic matter. This process typically takes several days to weeks, depending on factors such as temperature, feedstock composition, and digester design.
