Jochen Aigner

Company founder and managing partner

Jochen Aigner holds an MBA in International Management and many years of international industry experience in the energy supply area, gained at one of the world's construction material multinationals. He is a specialist in demand-oriented planning and the management of fully integrated energy generation production plants for industrial clients. He founded INDREC GmbH in 2016 with the aim of using waste residues even more efficiently as a sustainable energy producer in order to make a contribution to the energy transformation and to thereby improve our quality of life.
Integrity is of particular importance to our company. It guides all of our actions and our interaction with our customers, staff, the company and our business partners.

Milan Maciga

Chief Technology Officer

Milan Maciga, BSc, studied economics in Prague. For more than fifteen years, he held various management positions in the cement industry, primarily in the production, process and quality areas. He has been involved with many projects, often holding the ultimate responsibility for them; since the mid-2000s also in the environmental area, where he was responsible for the countries Slovakia and the Czech Republic as a general manager for an international group of companies. Maciga's past projects include the construction and start-up of a new tilting rotary furnace line, including "HotDisc" installation, in Slovakia and the construction and start-up of the largest production plant for alternative fuels in the Czech Republic with an annual capacity of more than 100kt/pa.
We set benchmarks–because we are constantly looking for new meaningful applications for our products and services, thereby securing our position as a technology and innovation leader.

What does "industrial recovery" mean?

The name of our company, INDREC, is an acronym and stands for industrial resource recovery. Resource recovery is the selective recovery of materials from residues for a specific recycling purpose; i.e. this term refers to the recycling of materials, but also to the generation of energy from residues, so-called refuse derived fuels ("thermal recovery"). The aim is to maximise the use we get out of materials, to extend the lifetime and to thereby reduce the volume of waste–always with a view to achieving a well thought eco-balance.


Sustainable energy for the industry from waste materials

On the one hand, there are the waste management companies that are increasingly battling against the rising volumes of waste produced, which they have to collect: Waste combustion, or waste-to-energy plants have huge volumes of waste to deal with and are slowly reaching their installed capacities. On the other hand, the energy intensive industries such as the cement, steel, and lime industries and the chemicals industry, as well as CHP plants require vast amounts of energy. INDREC brings these two sides together: State-of-the-art separation and production systems make it possible to use specific non-recyclable waste as sustainable fuel for the industry in accordance with pre-defined standards. We see ourselves as the interface between waste management and the energy-intensive industries. Together with our partner companies, INDREC produces and supplies refuse derived fuels, thereby making waste usable for the industry. The industrial companies benefit from sustainable and high quality energy; the waste management companies from a sustainable collection and the environment from the use of sustainable energy sources. INDREC takes over the corporate responsibility, thereby contributing to the protection and conservation of the environment.


How to switch to refuse-derived fuel

Refuse-derived fuel (RDF) is a fuel made from non-recyclable or no longer recyclable industrial and commercial waste which then has to undergo several treatment and production stages in mechanical production and separation plants.

Industrial use

Along with conventional fuels such as coal and gas, refuse-derived fuels are primarily used in energy intensive industries such as the cement, steel or lime industry.
