What is biogas?
Biogas is a renewable energy source produced from organic materials such as animal manure, food waste, and plant residues. It is composed primarily of methane (CH4) and carbon dioxide (CO2), along with trace amounts of other gases. Biogas is considered a clean, eco-friendly alternative to fossil fuels and plays a key role in reducing greenhouse gas emissions and supporting the global shift toward renewable energy.
How is Biogas Manufactured?
The process of manufacturing biogas involves anaerobic digestion, a natural process where microorganisms break down organic matter in the absence of oxygen.
How biogas is made
Raw Material Collection: Organic waste materials such as household manure, food scraps, or agricultural residues are collected. At Moobio, we also use fish ensilage in combination with household manure for a more potent biogas outcome.
Anaerobic Digestion: The organic waste is placed in an oxygen-free environment, typically in a specially designed digester. Inside the digester, bacteria break down the organic matter, producing biogas as a by-product. This process typically takes place over several weeks, depending on the type of material and the system used.
Refining: In some cases, the raw biogas may be cleaned or upgraded to remove impurities, increasing its methane content. This purified biogas, often called biomethane, is more efficient and can be used in a wider range of applications.
Gas Collection: As the organic matter breaks down, biogas is released and collected from the top of the digester. The remaining material, called digestate, can be used as a nutrient-rich fertilizer, creating a sustainable cycle.
How Can Biogas Be Used?
Biogas is a versatile energy source that can be used in various ways to meet energy needs.
How to use biogas
Electricity and Heat Production: Biogas can be burned in a combined heat and power (CHP) plant to generate both electricity and heat. This is one of the most common uses of biogas, providing sustainable energy for homes, businesses, and industries.
Vehicle Fuel: Purified biogas (biomethane) can be used as a clean fuel alternative for vehicles. Biogas-powered vehicles help reduce emissions and dependency on fossil fuels in the transportation sector.
Cooking and Heating: Biogas can be used directly in gas stoves for cooking and heating in homes or commercial kitchens, providing a renewable and environmentally friendly alternative to natural gas or LPG.
Industrial Applications: Industries that require significant amounts of heat or steam can utilize biogas as a clean energy source, reducing their carbon footprint and energy costs.
Why is Biogas Important?
Biogas is not only a renewable energy source but also an effective solution for waste management. By converting organic waste into energy, biogas helps reduce methane emissions from landfills and lowers greenhouse gas emissions. It also supports a circular economy by turning waste into a valuable resource and producing digestate as a by-product, which can be used as a natural fertilizer.
At Moobio, we are proud to be part of the renewable energy revolution by manufacturing biogas from underutilized resources such as household manure and fish ensilage. Our biogas helps power homes, businesses, and vehicles while contributing to a cleaner, more sustainable future.
