Biokaasu

Biokaasu is a renewable energy source produced from the anaerobic digestion of organic materials. This process involves microorganisms breaking down substances like agricultural waste, animal manure, food scraps, and sewage in an oxygen-free environment. The primary components of biokaasu are methane (CH4) and carbon dioxide (CO2), with smaller amounts of other gases.

The production of biokaasu can occur in specialized facilities called biogas plants, or on a smaller scale in farm-based digesters. Once produced, biokaasu can be used in various ways. It can be burned to generate electricity and heat, often in combined heat and power (CHP) systems. Alternatively, it can be purified to remove CO2 and other impurities, creating biomethane, which is chemically similar to natural gas and can be injected into existing gas grids or used as a fuel for vehicles.

Biokaasu offers several environmental benefits. It helps to reduce greenhouse gas emissions by capturing methane that would otherwise be released into the atmosphere from decomposing organic waste. It also provides a sustainable alternative to fossil fuels, contributing to energy independence and reducing reliance on non-renewable resources. The digestate, the solid residue left after the biogas production, is a nutrient-rich fertilizer that can be used to improve soil quality.
