How we can help different companies in a targeted manner.
Discover how we can help different businesses in a targeted manner. From biogas plants and mills to wine and fruit farms.
One system. Many possibilities: from agriculture to industry. Our technology is as versatile as the challenges of the energy transition. Whether in agriculture, municipal waste recycling, or as a climate-positive solution for industrial processes, autarkize opens up new ways of using energy and materials sustainably. Each application not only creates benefits on site, but also has a real impact on the climate. Together with our partners, we develop solutions that pay off - ecologically and economically. Discover what is possible.
Industry
Generate climate-positive process heat directly on-site - independent of fossil fuels and with permanent CO₂ removal from the atmosphere.
Heating network
Use regional biomass waste to supply your heating network - climate-friendly, efficient, and a real contribution to the municipal heating transition.
Biogas plants
More efficiency, new sources of revenue and less waste: with pyrolysis technology from autarkize , you can turn fermentation residues into energy, CO₂ certificates and high-quality biochar.
Biogas plants
Separation and pyrolysis of the fermentation residues replace expensive storage and logistics and create additional revenue.
Biogas plants must be able to store their digestate for 180 or 270 days. If the fermentation residue store is full and spreading is not permitted or not possible due to the weather, the plant must be throttled in the worst case. In addition, in red areas it is often not possible to spread the entire digestate on the fields in the region; instead, it has to be transported to other regions at great expense. Biowaste and food waste fermentation plants also have fermentation residues that require energy-intensive sanitization before transport and are contaminated with plastic and microplastics.
Autarkize offers a real system change here.
The fermentation residues from a biogas plant can be pressed off via a separator and thus separated into a solid and a liquid phase. The solid phase is further dried with waste heat and processed into energy-rich pyrolysis gas and biochar in an autarkize plant. Thanks to the unique process, the pyrolysis gas from the autarkize has a similar energy density to the gas from the biogas plant.
Especially in plants that switch to methanation for feeding into the natural gas grid, there is an increasing shortage of biogas for self-supply - for example for heating the fermenter. Here, the pyrolysis gas from the autarkize can help to cover the plant's own energy requirements - independently, sustainably and economically.
Another advantage: biogas plants usually already have the right infrastructure - for example for separation, heat use and electrical connection. This means that our system can be integrated particularly efficiently and cost-effectively, without major conversions or additional investment.
At the same time, the process significantly reduces the amount of digestate produced, as the solid phase is recycled. The high pyrolysis temperatures (500-750 °C) make additional sanitization superfluous - even plastic residues and microplastics are treated without leaving any residue. This produces a high-quality biochar that can either be used as a soil conditioner or marketed as a CO₂ sink - including additional revenue through the sale of CO₂ certificates (CDR credits).
This turns storage, disposal and logistics problems into sustainable solutions and revenue.

The biochar from autarkize is not only a valuable soil conditioner but also a permanent carbon sink. Plants take CO2 from the atmosphere as they grow and use the carbon to build their cells and structures. Normally, this carbon bound in the plant is converted back into CO2 by rotting or burning. However, the autarkize converts a larger proportion of the carbon into a stable biochar. If this carbon is then introduced into the soil, for example, it can hardly be decomposed, and the CO2, once bound, is permanently removed from the atmosphere.
Each autarkize plant removes several thousand tons of CO2 from the atmosphere every year. Producers and users of autarkize biochar can receive certificates for this immensely important contribution to climate protection. The so-called Carbon Dioxide Removal (CDR) credits are issued in quality-assured processes and are purchased by companies and private individuals on international exchanges, for example.
The CDR certificates not only show the important contribution that farmers and biogas plant operators can make to climate protection. They are also a good, additional revenue stream and offer companies and private individuals the opportunity to offset their partially unavoidable greenhouse gas emissions locally in domestic cultivation areas.
Use the biochar produced yourself or market it as a soil conditioner and fertilizer.
The biochar produced in the process meets the high standards for use in agriculture, viticulture and fruit growing as well as in horticulture and landscaping. This opens up a wide range of possibilities for biogas plant operators.
biochar can be used directly on your own farm as a soil conditioner. Thanks to its porous structure, it stores nutrients and water particularly effectively, supports soil microbiology and contributes to humus formation in the long term. This improves nutrient efficiency and increases the resilience of the soil - a real benefit for yield and the environment.
biochar that is not used on the farm can be easily marketed - for example to agricultural businesses, horticultural companies or manufacturers of special substrates. This turns biomass into a sought-after raw material - and an additional source of income for the farm.
Sustainable, certifiable, economical.
COmposting
Biomass that was previously difficult to use becomes a valuable raw material - and classic compost becomes a genuine premium product.
Coarse wood residues are a recurring problem in composting practice. Even on delivery, larger pieces of wood are sorted out as so-called screenings. Even after shredding, they are often only suitable for further compost processing to a limited extent. The result: high disposal costs, unnecessary costs and unused potential.
Instead of disposing of these valuable resources, they can be efficiently recycled with the autarkize. Our technology converts the woody screenings into energy-rich pyrolysis gas and high-quality biochar. The gas can be used directly to dry the compost or to generate electricity - a plus in energy efficiency in your own business.
However, the real added value lies in the biochar: it can be added directly to the compost substrate on site. The result is an enhanced product with improved soil-improving properties - richer in nutrients, more structurally stable and more climate-friendly. At the same time, a higher sales price can be achieved thanks to the high-quality composition.
This turns biomass that was previously difficult to use into a valuable raw material - and classic compost into a genuine premium product.

Use biochar sensibly or market it as an additive
The biochar produced in the pyrolysis process meets the highest quality standards and is ideal for use in horticulture and landscaping, agriculture, viticulture and fruit growing. For composting companies, this opens up new opportunities for product refinement and added value.
biochar can be added directly to the compost substrate on site. It improves the structure, increases the water holding capacity and acts as a depot for nutrients and microorganisms. The result: a more stable, nutrient-rich compost that is both agronomically and ecologically convincing - and can be marketed as a high-quality substrate at better prices.
biochar that is not used by the company itself can also be easily passed on to third parties - such as farms, nurseries or manufacturers of specialty soils. This turns a by-product into a sought-after additive with real climate benefits.
Industry
Climate-positive process heat for future-proof production sites
Industry is under increasing pressure to decarbonize its energy supply - whether due to rising energy costs, regulatory requirements, or the desire for more sustainable business practices. The pyrolysis plant from autarkize enables industrial companies to generate CO₂-neutral process heat directly on site - independently of fossil fuels and with a double ecological added value: CO₂ avoidance through regenerative heat production and active CO₂ removal through the biochar produced.
Our modular technology converts biogenic waste materials into valuable energy. This not only produces usable heat for your processes, but also a stable and certified biochar in which carbon is permanently bound and thus removed from the carbon cycle in the long term. This process is known as carbon removal, which can be certified and monetized through certificate trading.
The result: a reliable, scalable, and climate-positive energy source that pays off economically and measurably supports your sustainability goals. Whether in food processing, the woodworking industry, or agriculture, autarkize brings CO₂-neutral process heat to where it is needed.
Heating network
Rethinking regional heat supply - with real climate benefits
The heating transition is one of the biggest challenges facing municipal energy policy. At the same time, there are new opportunities for cities, municipalities, and energy suppliers: with autarkize's pyrolysis technology, regional biomass and green waste can be converted into climate-friendly heat and fed directly into the local heating network.
Our pyrolysis systems generate CO₂-neutral energy from biogenic residues that have often remained unused until now. The resulting pyrolysis gas is converted into heat via a gas burner - ideal for feeding into local or district heating networks. At the same time, a stable and certified biochar is produced, which reduces the greenhouse effect in the long term and can be monetized as a certified CO₂ sink.
The autarkize is particularly attractive for regions with available biomass resources, municipal climate targets, and the desire for local value creation. The systems are modular, expandable, and highly interesting from an economic point of view, especially where heat is needed permanently.
In this way, regional waste utilization becomes a real contribution to the heat transition - with a noticeable effect for the climate, the community and the population.
Wine and fruit farms
Extract activated biochar from vine and tree prunings and pomace to improve the soil and become energy self-sufficient.
Viticulture and fruit growing increasingly require climate-resilient soils that store water and nutrients well and promote plant growth and nutrient supply through active soil life. At the same time, many tons of vine and tree prunings, grubs, and pomace are produced every year, for which removal and disposal must be organized.
An increasing number of vineyards and orchards have already had positive experiences with the use of biochar. However, many of the products available on the market are too expensive for large-scale use.
Vine and tree prunings are high-quality input materials for autarkize systems. Vine and fruit growers transport these to a centrally located plant. There they are stored, dried and shredded, and continuously fed into an autarkize system.
In its unique process, the autarkize plant produces high-quality biochar and pyrolysis gas, from which electricity and heat are generated with the help of a combined heat and power plant. The plant is usually set up near a commercial or industrial operation or a municipality in order to cover its energy requirements with climate-neutral, locally generated energy.
The resulting biochar can be fermented together with the pomace in a further step and thus become an optimal soil conditioner and fertilizer for wine and fruit cultivation.
Additional revenue can be generated through the sale of CO2 certificates (CDR credits).
This turns a waste disposal problem into a regenerative energy supply, climate-resilient soils, better-supplied vines, shrubs, and trees, and ultimately, monetary revenue.

They are also a good, additional revenue stream and offer companies and private individuals the opportunity to offset their partially unavoidable greenhouse gas emissions locally in domestic cultivation areas.
Generation of electricity and heat
The unique autarkize process enables the production of an energy-rich pyrolysis gas from the green cuttings of wine and fruit growers. Other biomasses such as pomace, municipal green waste, and forest residues can also be added. The pyrolysis gas is of a quality that can be converted into electricity and heat in conventional combined heat and power plants.
This saves costs and complexity. The electricity generated can be used on site (e.g., by a commercial enterprise) or fed into the public grid and remunerated following the German Renewable Energy Sources Act (EEG). This provides the system operator with a secure source of income.
The heat can also be used on-site by an industrial or commercial enterprise or fed into a local or district heating network. As the autarkize systems are very compact and transportable despite their high generation capacity, they can be easily installed where there is a high demand for energy.
Use the biochar produced yourself or market it as a soil conditioner and fertilizer.
The biochar produced in the process meets the high standards for use in agriculture, viticulture, and fruit growing, as well as in horticulture and landscaping. This opens up a wide range of possibilities for wine and fruit growers.
Firstly, they can ferment or compost the biochar on site together with their pomace. This produces a carbon activated with nutrients and microorganisms, which can be used in their cultivation areas to improve the soil, microbiology, and nutrient supply to the plants.
biochar that is not used by the farmers themselves can also be sold on to other farms, private individuals, or larger substrate producers.
MILL OPERATIONS
Becoming energy self-sufficient with mill residues and closing material cycles.
The production of products in grain and feed mills requires a lot of energy in the form of electricity, heat, and often also process steam. Most mills are dependent on external supplies for these forms of energy. Especially for heat and steam generation, there are usually no renewable sources available; instead, there is a dependency on fossil fuels and their markets.
At the same time, residues such as husks, hulls, and bran are produced during milling operations. These are usually passed on to biogas or composting plants, for example, at little or no cost and with technical and logistical effort.
Mill residues are an excellent input material for autarkize plants. Due to the compact design of the plants, they can be easily integrated into existing mill sites and material flows.
With the help of autarkize technology, an energy-rich pyrolysis gas is produced from the mill residues, which can be used to generate electricity and heat in a combined heat and power plant and steam in a steam boiler. Mills can thus cover a large part or even all of their energy requirements with their residues and become self-sufficient.
At the same time, a high-quality biochar is produced. This can be passed on directly to the supplying arable farms, for example, where it can be used to improve the soil or sold on the market.
As biochar has similar properties to activated carbon, it can also be used by feed mills in innovative feed mixtures.

Climate-neutral electricity and heat or steam - and less logistics
Many mills operate in 24/5, 24/6, or 24/7 mode. Screening, milling, or peeling residues are constantly produced. As these can often not be used on site, they are temporarily stored in silos, for example, and regularly transported by truck to further processors such as biogas plants or animal feed manufacturers.
As autarkize plants are also designed for 24/7 operation and process the mill residues, which are still rich in energy, in the best possible way, they can be upgraded to biochar and pyrolysis gas as an Input directly at the production site in an autarkize plant with no or only short intermediate storage. In combination with combined heat and power units and steam boilers, autarkize systems provide up to 1.2 megawatts of energy for the mill from its residual materials and make the mill independent of energy supplies.
Thanks to their compactness and optional container design, autarkize systems can be easily integrated on the company premises. This drastically reduces storage and logistics costs.
Market the biochar produced as a soil conditioner and fertilizer
The biochar produced in the process meets the high standards for use in agriculture, viticulture, fruit growing, horticulture, and landscaping.
Mill operators can sell this biochar directly on the market or activate it on site in further refinement steps with microorganisms and nutrients, and then market this terra preta product.
The marketing/passing on of biochar to the supplying arable farms is particularly appealing. This creates a closed cycle that first supplies flour, for example, from the harvested grain, then energy, and finally improves and fertilizes the soil on which the grain grows.
