SWESTEP AB is a privately owned company which is part of the Sustainable Technology Group AB. SWESTEP is a green technology pioneer that develops, sells and operates SWESTEP plants that utilizing the revolutionary CPD process developed for over 40 years in Siemens Lab with proven plants operating. Our company’s vision is to build the world’s largest waste to renewable fuel and sustainable liquid and material production grid along with cloud connectivity and provide solution and services to industries around the world.

The company stands on three pillars:
1. Sales of SWESTEP Plants
2. Research and Development of SWESTEP Plants
3. Maintenance and Operation (optional) of SWESTEP Plants

Head Office in Sweden.


Variations of transport fuel for transportation on land, air and sea; Renewable fuels, lubricants, oil and additives for industry and heating oil for homes, offices and more.

Variations of sustainable and circular liquids and oils to refine and develop to new polymers, fibers or other products for the fossil dependent industry.

Variations of new green performance chemicals for the petrochemical industry to refine into circular end products, materials and liquids.


SWESTEP’s business model is to responsibly develop, manufacture and sell SWESTEP plants. Each plant is built to provide a viable and sustainable alternative in order to work towards eliminating the world’s fossil dependence.

The core business – Sales of SWESTEP Plants.

Each SWESTEP plant is connected to the cloud with its daily output recorded and tracked for easily relocation.

Revenue is primarily generated through the following sources:
• Sales of plants
• Operation of plants
• Sales of valuable end products
• IP rights licensing
• Tests
• Organisation of workshops, studies and seminars


The demand for renewable fuels and sustainable liquids used to produce circular and climate friendly products is global scaled. Since the Industrial revolution, production of greenhouse gases and toxic chemicals have escalated tremendously, which has resulted in an urgency to replace fossil fuels with renewable alternative energy sources. At present, the UN and the EU have all created directives to encourage the utilisation of renewable fuels.

SWESTEP’s technology delivers a capital-efficient and profitable solution that offers renewable fuels and sustainable liquids and material alternatives.

Residues from the forest (biomass) and the municipal waste (MSW) is existing globally and is more than sufficient to replace the fossil dependence. In the future, conversion of organic waste, incl. plastics, to all kind of renewables (closing the loop) will be a large commodity, alongside energy solutions from water, solar and wind.

100 years have passed between the first Nobel Prize honoring
“The discovery of coal liquefaction” and Dr Christian Koch’s CPD Process
  • 2018

    After successfully performed tests and studies during the last 12-month and implementation of the latest generation of the CPD process is SWESTEP ready for roll out of the –“Next Generation Process Technology for Sustainable Recycling production”-. Priority is Sweden but also Europe and countries in Asia is in the pipeline. Installations planned to start latest Q1 2019. To sett up a combined R&D SWESTEP Plant in Sweden is also on the agenda. SWESTEP will offer seminars, workshops and studies, both under own management and with primarily KTH (The Royal Institute of Technology in Stockholm, Sweden) but also in collaborations with other universities around the world. SWESTEP deliver the missing puzzle piece in the renewable portfolio (Solar, Wind and Hydro/Water). – So if you don’t want our planet to disappear in smog and continue consuming fossil fuels until the end of time, join us and be a part of the solution, not the problem.

  • 2015

    In order to offer the market a turnkey production plant, the focus is now on R & D to gain and maintain control of production flow from A-Z. The production must become automated in order to guarantee the market control of the production process. The work resulted in an escalation, from forty censors to more than two hundred to ensure a controlled flow in industrial production.

  • 2010’s

    In the beginning of this decade, Karl Magnus Mattsson (The founder of STG and SWESTEP AB) and Dr. Christian Koch (The Inventor of the CPD process) met for the first time. This led to a fruitful partnership where SWESTEP will play an important part in the commercialization and productification. The focus moved to defining the market, searching and/or developing new Front-End and Back-End technology to be integrated with the CPD process to offer the market a turnkey plant that is both profitable and viable from a climate perspective; The goal is to develop, produce and offer a Plant “The SWESTEP Plant" that meets all the demands the market have.

  • 2000’s

    The first generation of plants based on the CPD process were set up, but with variation in results. This led to an intensive period of further research and development of the technology to guarantee a more reliable and sustainable process for industrial production of synthetic diesel. New generations of the plant were developed and sold in Mexico and Spain.

  • 1973

    Dr. Christian Koch started his research and work with the technology from the Nobel Prize. From 1973, he started working at Siemens until the research institute eventually closed down. During the time, we received a patent instead of a redundancy payment to continue his research and development the technology on his own. He focused heavily on R&D into the end products and the industrial manufacturing equipment. The research results made it apparent that it was possible to transform even brown coal into diesel oil. Eventually, he successfully pioneered and invented the Catalytic Pressureless Depolymerization (CPD) process and identified the natural catalyst in biomasses. With persistence, he perfected the technology which became capable of converting any organic materials into useful fossil-like liquid in just a matter of minutes instead of 175 million years.

  • 1931

    The Nobel Prize for Chemistry was awarded jointly to Friedrich Bergius and the chemist and chairman of the board of directors of the I.G. Farben, Carl Bosch, “in recognition to the invention and development of chemical high pressure methods”.

  • 1923

    Fischer and Tropsch further developed this technology. In Germany as well as in other parts of the world, scientists intensively worked on the procedure of coal liquefaction known under the term of FT to improve this technology as it was still relatively expensive compared to the production of fuels from crude oil. Today, these processes are still in operation in South Africa and China. However, in Europe, plants were shut down decades ago due to the high environmental burden and the economic inefficiency. China have also cut further investments into this technology, in view of the high costs, the extreme consumption of water and the unbearable environmental burden.

  • 1913

    An employee named H. Speckens transformed the carbonization product of peat into a benzene similar to organic liquid at 450 °C and under a hydrogen pressure of 150 atm in the private lab of Friedrich Bergius. Further experiments with brown and black coal also produced the benzene similar to organic liquid. In the same year, Friedrich Bergius filed a patent application for a procedure for “coal-to-liquids” – the Bergius-Pier process.
