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 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.
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.
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.
Advantages for producers:
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.
You want to get the highest return of your investment? So do we. The new plant technology is far more efficient than it was years ago. Moreover, as the owner of the existing plant, you want to stay competitive. Your system can be most easily adapted to the latest technological developments. An investment in the" health" of your investment is worthwhile, because it usually pays for itself in a short time.
Depending on the plant quality we offer
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.
The advantages of biomethane at a glance:
Before biogas can be fed into the natural gas grid or used as a fuel, it must first be upgraded to natural gas quality. Our answer to the requirements of the future is therefore EnviThan – our integrated solution from organic waste to the filling station pump!
