Whether as a source of electricity to generate heat locally, to supply heat by pipeline or to feed into the gas network after processing - Biogas is multi-talented and versatile. The weather-independent generation is a predictable source of revenue for the operator, since energy from biogas is not subject to any price fluctuations. At the same time, a biogas plant actively contributes to environmental protection and energy mix of the future.
Agricultural companies have the opportunity of generating valuable, sustainable and renewable energy with by-products of their business such as liquid manure, biomass and organic agricultural waste. Generating biogas offers plant operators a source of revenue that can be accurately calculated for years – which is a factor that can be decisive for the long-term prospects of a farming business.
Many farmers use biogas production to establish a second economic mainstay, thereby ensuring that their agricultural enterprises continue to flourish into the next generation.
All types of agricultural raw and residual materials can be used in our biogas plants. This assures farmers a healthy crop rotation and helps them prevent monocultures. Even catch crops, whole-plant silage and energy beets deliver top yields.
Decentralised biogas production using independent resources strengthens the added value in rural areas. Using renewable resources effectively reduces the dependence on foreign energy imports, so that revenues remain in the region. More and more bioenergy villages are showing us how biogas can be used to get the most out of local synergies.
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 a fertiliser with a high nutrient content, these fermentation residues relieve farmers from purchasing expensive mineral fertiliser.
Our field-tested EnviFarm biogas plants offer you a flexible choice of input materials, and are tailored individually to your business and your specific requirements. As an alternative to being run as slurry-only plants, you can also operate them with biomass or with any type of organic waste. The stable and spacious technical building offered by an EnviFarm plant allows optimum temperature control with innovative ventilation technology, plus weather-independent operation and storage.
EnviFarm is equally impressive in its compact version (plant output from 75 kWel). The modular, container-based format means EnviFarm can be installed as a compact plant that makes the most of available space. Whatever the model, all our biogas plants have one thing in common: impressively high efficiency and maximum profitability.
Driven by our technological farsightedness and the very highest quality standards, we’ve been researching additional technologies capable of optimising biogas plant usage from the very start. And this hard work has paid off: our ‘Kreis Dissolver’ mixing system offers impressively high substrate savings and higher gas yields, for example. Our EnviTec Feedcontrol feeding system maximises the capacity utilisation of your biogas plant, saving you valuable input materials.
Those who opt for a biogas plant have learnt early on that it is not only the scope of such a project that presents a challenge. Even an intelligent energy concept and cooperative integration of the vicinity and environment require an intensive discussion.
The following projects show how we have used completely different starting scenarios to build a single, successful model.
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.
Several companies and communes make use of the financial assistance that the political system provides for the realisation of the energy-related potential of waste management or just benefit from producing their own energy. Since the year 2002, we have developed technologies for biogas plants that produce impressive income from food waste, glycerine, slaughterhouse waste and fats.

Biomethane upgrading opens up a promising future market for the biogas industry. With feed-in into the public natural gas grid, the green all-rounder is perfect for the decentralised supply of energy, offering a long-term replacement for fossil natural gas and driving the energy transition forward. What’s more, the biomethane manufactured in the gas upgrading plant has the exact same properties as natural gas, being just as flexible in its usage and easier to store than other energy sources. Plus, it’s renewable.
Anaerobic digestion of organic materials creates a gas composed of methane and carbon dioxide. To upgrade the biogas to natural gas-quality biomethane, the crude gas is first purified and compressed. The membrane technology we use then exploits the different sizes and permeation speeds of the two kinds of gas molecules involved: since carbon dioxide molecules are smaller than methane molecules, they can migrate through the membrane much more quickly. As a result, the methane remains on the high-pressure side, while the CO2 molecules in the biogas pass through. As a result, the gas upgrading needs neither chemicals nor water nor any other resources.
The starting point for producing biomethane doesn’t have to be biogas, however. After a preliminary purification stage, gas from landfill and wastewater treatment plants can also be used to produce biomethane.
The biomethane so produced is the all-rounder among renewable energy sources, and can replace fossil fuel-based natural gas anywhere it is used. On the following pages, you can find out about the many uses for this valuable and renewable natural gas, and how it can play a part in an environmentally-friendly energy supply system.
Our EnviThan concept offers an all-round carefree package. We provide you with an integrated solution from pre-treatment and raw gas purification, the treatment of biogas in biomethane quality to the final utilisation of the gas.
EnviTec Biogas - a strong partner from start to finish.
From a macroeconomic and climate perspective, biomethane is now the most cost-effective, climate-friendly fuel for achieving progress towards climate targets and sustainable transport in Germany and the EU. The all-round talent is virtually carbon-neutral and can be stored, which means it is continuously available, making it attractive not only for the transport sector!
In addition, the all-rounder can be used wherever fossil natural gas had been used: this includes CHP applications, demand-based power and heat generation and use as a material in the chemical industry. Biomethane is therefore an important building block of the energy transition.
The advantages of bio-LNG (liquefied natural gas) as a carbon-neutral fuel are obvious: in the transport sector alone, the use of biomethane allows a CO2 reduction of up to 97 percent compared to fossil fuels.
For this reason, we are tapping into a new field of the future as a plant manufacturer by constructing Germany's first integrated bio-LNG plant, which will both make heavy goods transport greener and also allow biogas plant operators to profit. This is because the reduction in greenhouse gas emissions required of the German fuel mix by the Renewable Energy Directive RED II means that green fuel production is being implemented ambitiously for the first time. As a result, those placing fuels on the market must now cut their GHG emissions by 25 percent by 2030 compared with 1990 levels.
Following the expiry of state subsidies for biogas plants, our all-round concept for gas treatment offers a sustainable solution for the profitable continued operation of existing plants through the sale of your biomethane or potentially its contract liquefaction into bio-LNG.
Cost-effective, efficient and reliable technology, plus smart business models that cover the entire value chain for the biomethane market. Our expertise is in demand worldwide.
