Who we are and what we do
We started when biomethane in Poland was still just a vision. Today, we implement real projects, combining knowledge from energy, chemistry, and agriculture. We are a team of specialists who know how to turn an idea into a working installation – from a “blank page” to a complete facility.
Necessity is the mother of invention
This saying perfectly reflects the beginnings of our company.
Today, the biomethane market is beginning to develop dynamically – dozens, and perhaps even hundreds of plants producing this gas so vital to our economy will be built in Poland. However, in 2021, when we started our operations, this wasn’t so certain. While biomethane plants were already common in many European countries and worldwide, they were still missing in our backyard. Finally, this great opportunity was also recognized in Poland, where the first “pioneers” began taking steps in this direction.
Our History
Reasons for establishing a dedicated company
The beginnings of biomethane in Poland had their difficulties. Undoubtedly, besides regulatory and formal limitations, the challenge for future investors was the lack of quality projects, particularly those with administrative decisions that would enable the implementation of such ventures.
There was also a lack of professional entities that could prepare the construction of biomethane production facilities. This was mainly due to the fact that such activities require appropriately broad competencies in many different areas such as investment project management, process technology, and agriculture.
Another missing yet extremely important element of the investment puzzle included suitable properties located in appropriate locations away from buildings with access to gas distribution networks, as well as experience in implementing large and complex projects, especially for the energy and fuel industry.
And above all, selecting people who can talk to people, understand their needs and concerns, because there is no successful biomethane project without cooperation with the local community
Year 2021 - establishment of Green-en
Faced with a challenge that many might consider too bold, we decided to act and take up the gauntlet! That's how, in 2021, Green-en was born - from passion, experience, and the conviction that change begins with the decision to take action!
Its founder had been commissioning new power plant projects in various parts of the world since 2007, and since 2011, he had been using his gained experience to build new capacities in Poland. He developed projects for new methane-powered power units. He prepared investments from the concept “blank page” stage to construction commencement, while simultaneously creating teams servicing large energy units, which successfully maintain them to this day.
In subsequent years, he also developed projects for large chemical installations requiring special attention to production safety, both for workers and nearby residents.
From vision to cooperation - how we create Poland's biomethane map
The first period of the company's operation focused on deepening knowledge about technology, initial attempts to adapt it to national realities, as well as establishing contacts with substrate suppliers, offices and utility operators, and most importantly with residents, who are the most important factor determining the success of the venture.
In 2023, a new partner joined the company, bringing unique knowledge, tools, and experience for the best possible selection of locations for new plants. This modern approach allows us to locate installations in a way that best fits into the surroundings and maximizes benefits for local communities.
Biomethane instead of deposits - a new opportunity for agricultural municipalities
Biomethane instead of deposits - a new opportunity for agricultural municipalities
We want to jointly create the best investments that will allow local residents to become producers of methane, which serves both as fuel and as a raw material for the chemical industry. It’s widely known that having natural deposits like coal, oil, or gas is a great benefit for a municipality. This is evidenced by the lists of the wealthiest municipalities in Poland. Biomethane gives such an opportunity also to municipalities that don’t have such resources but have developed agriculture in their surroundings, especially livestock farming or agri-food processing.
We develop projects and our team of specialists
The company currently runs projects in over half of the country - at various stages of development.
We are developing dynamically, increasing both our internal resources and collaborating with leading industry partners in design, technology, administration, and many other areas. Our team consists of experienced specialists from various fields: technology, agriculture, property acquisition, investment development, architecture and urban planning, energy, and chemistry.
Biomethane - we build it together
Green-en is people - working with people and for people.
Our projects are created in cooperation with local communities because we understand that true value comes from working together toward a common goal. By building biomethane production facilities, we invest in regional development and the security of their residents, because long-term partnership is the foundation of success and guarantee of every venture’s success.
Green-en management
Experience and reliability you can count on.

Maciej Kropidłowski
Since 2007, he has been involved in planning and implementing investment projects for the energy and chemical industries, starting from work at Siemens A.G. and power plant projects, through the largest oil sector concern in Central and Eastern Europe, where he was responsible for developing chemical and energy projects as well as maintaining energy operations, including implementing energy projects for own needs and developing offshore wind energy. From 2019, Maciej developed chemical and energy projects for Synthos S.A., Europe’s largest producer of rubber and polystyrene, as well as project management structures, then started his own business and supported companies such as Polish construction market leader Erbud S.A. in developing offers and acquiring energy transformation projects, particularly in biomethane, hydrogen, and recycling.
