Turning waste into biogas

Waste materials and by-products are accrued in conjunction with every single manufacturing operation, such as enterprises associated with the food and restaurant sector, the fuel industry, the cosmetics sector and the animal husbandry sector.

However, the quantity of organic waste produced by the citizenry is also significant for communes – about half a tonne per year per person.

In addition to saving you the trouble of disposing of your residual products, our biogas technology also makes it possible for you to convert the waste into useful energy.

Advantages for producers

  • Own energy from cogeneration : electricity, steam and heat
    Biogas can be used as a source of electricity or to generate heat. After it has been processed into biomethane, it may also be fed into the gas grid. In case of industrial utilisation, the heat that accrues in conjunction with the combustion process taking place in the CHP can be returned to the company in the form of process heat. This is particularly worthwhile for energy-intensive companies with high heat requirements. It makes it possible for such companies to save on heating expenses.

  • Odour-free, natural fermentation residues for agriculture
    If a biogas plant is operated properly, there are no odour nuisances since the produced gas cannot escape from the closed cycle. The fully fermented end product has a noticeably reduced odour after the fermentation process. As high-nutrient fertilisers, these fermentation residues make it unnecessary for farmers to purchase expensive and pollutant mineral fertilisers.
  • Filtering and cleaning the digestate residues to process water
    Ultra-modern filtration technology makes it possible to further process the digestate. This procedure yields processed service water that can be used for the subsequent industrial process.
  • Improved CO2 balance
    Thanks to the high energy yield in the EnviWaste plants, the required amount of fossil fuels undergoes a reduction, resulting in a considerable improvement in the CO2 figures of production plants. This gives you an important competitive edge, as more and more consumers and companies are emphasising sustainable production when purchasing products.

What kinds of waste are suitable for energy production?

Many organic waste materials are well-suited for use as raw materials in biogas production. In manufacturing, substrates with a high calorific value are often found as waste materials and by-products

  •  Slaughterhouses
  •  The food-production industry and the food-processing industry
  •  Supermarkets, e.g. spoiled food products
  •  Breweries (malt spent grains)
  •  Restaurants
  •  Juice production
  •  The ethanol industry (mash)
  •  The biofuel industry, e.g. glycerine
  •  Animal hunbandry
  •  Purification plants: Sewage sludge
  •  The animal feed industry
