Biogas For Energy Generation

BioGas

Food losses and food waste

Roughly one-third of the food produced in the world for human consumption every year is wasted. This waste is generated during the production period, in the markets, restaurants, and by final consumers.

On the other hand, food losses are generated until the food is on the market and sometimes are a signal of without pesticide and chemical production.

When adding animal manure to the food loss and food waste, as a result, there is a huge quantity of biomass that could be turned into biogas. This process is happening in anaerobic digestion treatment. It is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen and biomass is converted into biogas and biofertilizers.

This is exactly how the energy will be generated in The Distrikt using the food waste and animal manure collected from neighboring communities.

From waste to energy

Biogas can play a major role in the developing market for renewable energy as a substitute for natural gas and fossil fuels.

The input sources are just industrial and commercial organic waste, bio waste from households, animal by-products, and plant by-products. The purified form of raw biogas can be used in various applications such as the production of electricity, heat and steam generation in households and industry, injection into the natural gas grid as well as a vehicular fuel. The second by-product is biofertilizer. Its application helps return organic carbon into the soil and reduces demand for the carbon-intensive production of mineral fertilizers.

Night-time energy production challenge for The Distrikt

Biogas will be one of the main energy sources in The Distrikt for residential and industrial use together with solar energy and geothermal heating and cooling system.

For the households, biogas will be the night-time energy supplement. For the aquaponics and waste treatment plant greenhouses biogas will be used as the major energy source.

The input biomass sources will be collected by the local households and industries. The collection of the input materials will be organized with the recycling infrastructure available in The Distrikt for the residents, local enterprises, and adjacent neighborhoods.

Biomass sources for The Distrikt

  • null

    Food residues form The Distrikt households

  • Biogas

    Food residues from the local restaurants and markets

  • Biogas

    Agricultural waste from the local communities

  • biogas

    Animal manure from the local communities

Overall, biogas will reduce the dependence on fossil fuels and pollution in Gyumri and meanwhile solve the waste disposal issue. For now, most of the waste ends up in the landfill and in rivers. This energy use will be an important contribution to meet Gyumri Green City Action Plan goals.

Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment.

WWF

Biogas has gained popularity in recent years as a “greener” fuel. This is the methane created when anaerobic digestion breaks down organic matter, like in landfills or “digesters” that convert animal manure or food waste, which can then be used to replace conventional natural gas.
