Currently the company is formed by four founders. Over the coming months we envision expansion of the number of people involved with the company.
We will look for both professionals and students to form our team.
During that coming year we will publish vacancies as we grow, that will include vacancies for directly hired and outsourced personnel, as well as for trainees.
Please keep your eye out for opportunities on this website.
Update March 2025
We welcome students aged 18 years or older, to apply for practical work and school or uni-assignments. We have capacity for teams of two persons for practical work and one school or uni-assignment.
Roeland Jan Dijkhuis has 12 years of international experience in commissioning heavy equipment for the metallurgical industry. Once a goal has been set he draws the path towards it and drums the beat.
Harmen Oterdoom has 20 years of experience in the design and commissioning of ferro-alloy and slag production processes and furnaces. The combination of research and hands on experience during the toughest periods of operation in metallurgical plants makes him one of the world experts in the field. Harmen is driven by intellectual correctness and is the groups technological and social consciousness.
Wiebe Pronker has a career behind him in mechanical engineering and people management. He is the developer of the DCI™ reactor and of many other industrial initiatives. Wiebe is the idea man of the group and it is hard not be influenced by his positive vibe and overall enthusiasm.
Michiel Spits has over 25 years of experience in power plant design and metals industry as well as people management. He excels in combining entrepreneurial, practical and managerial skills making him the ideal man for linking industrial partners to form circular business models.
Not only people working at our company are fundamental to realise our goals, other companies are too. Currently we are working together with the following partners to deliver DCI™ technology to the market.
DOPS Recycling Technologies Raises €5 Million for Waste Recycling Technology
Alkmaar, March 27, 2025 – DOPS Recycling Technologies has raised €5 million to further develop its groundbreaking Direct Carbon Immobilization (DCI™) technology. This innovative process converts waste into valuable raw materials without significant CO₂ emissions. The SEED investment round was led by the Rotterdam Energy Transition Fund, ROM InWest, the North Holland Innovation Fund, Init Power, CarbonFix, and Alphatron.
Every year, approximately eight million tons of waste are incinerated in the Netherlands, releasing an equal amount of CO₂ emissions and leading to the loss of valuable materials. DOPS Recycling Technologies offers a revolutionary solution with its Direct Carbon Immobilization (DCI™) technology, enabling the recovery of primary raw materials from waste without significant CO₂ emissions. For many waste streams, no sustainable processing method currently exists. DOPS employs advanced refractory materials and efficient heat recovery, making the system economically viable even at low volumes. Moreover, the technology can process various waste streams, which is highly needed in a circular economy. Through DOPS technology, these waste streams can be converted into biofuels, which are essential for decarbonizing energy-intensive industries and the transport sector.
Recycling Waste Without CO₂ Emissions
With DOPS’s DCI™ technique, complex waste streams and biomass are heated up to 1,000 degrees Celsius in an oxygen-free reactor. This process breaks down hydrocarbons into their basic elements: carbon monoxide and hydrogen. The DOPS technology makes it possible to convert over ninety percent of waste—waste that would otherwise be incinerated or landfilled—into new raw materials such as syngas, carbon (biochar or activated carbon), and other easily separable solid materials. Syngas plays a crucial role in the energy transition and is used as an industrial heat source and as a building block for methanol and sustainable fuels, among other applications.
DOPS’s technology is a platform technology—an essential enabler for transformative change. It paves the way for further development of the circular economy. Michiel Spits, CEO of DOPS Recycling Technologies, states: “Our technology ensures that waste is not the end, but the beginning of new, valuable resources. Thanks to this investment, we can scale up and contribute to the energy transition and a circular economy where reuse and efficient energy use become the norm.”
With this investment, DOPS will build a modular unit (M-DCI) to test the full system. This is expected to lead to a final investment decision for the first full-scale plant with customers.
Jesse In ’t Velt, Senior Investment Manager at the Rotterdam Energy Transition Fund, on behalf of the investors: “The transition to sustainable energy and a circular economy requires affordable green molecules that can compete with fossil resources for the industry and chemical sectors, along with more sustainable alternatives to waste incineration. With their robust and efficient gasification technology, DOPS transforms
existing residual streams into valuable chemical building blocks while drastically reducing CO₂ emissions. The DOPS team has the expertise and experience to scale this innovation and future-proof existing value chains. We look forward to working with the management and this group of impact investors.”
Support from the Start
Since its founding in 2021, DOPS received a voucher from the Energy & Climate innovation program and was one of the participants in the 2023/2024 Green Chemistry Accelerator (GCA) program. This program was established with Invest-NL and the Regional Development Agencies (ROMs) to help startups scale into mature businesses. It enables them to build pilot plants, enter the market, and ultimately produce thousands of tons of recycled or biobased raw materials.

Clients for DCI™ technology typically already run a 24/7 operation. They have goals to minimise waste going off site and it’s cost, reduce their carbon footprint, contribute actively to a circular economy and may even wish to diverse their feedstock.
Municipalities which would like to stop landfilling or even clean up existing landfills are more than welcome to explore the possibilities of the DCI™ technology.
Operators of waste to energy plants which wish to reduce their carbon dioxide emissions are welcome too.
We offer feasibility tests on your waste in our laboratory.
