Ioniqa announces a change in leadership

Ioniqa, a privately owned plastic upcycling company, announced that after 15 years, Ioniqa’s founder Tonnis Hooghoudt is handing over his CEO role to Michiel Hoogendijk as of July 8, 2024. Hooghoudt will remain shareholder of the company and stay actively involved as an advisor to the Management Team of Ioniqa.

Since Hooghoudt founded Ioniqa in 2009, he has fostered the development of Ioniqa’s catalytic upcycling technology Denua. Hooghoudt has steered the evolution of Ioniqa’s technology from lab scale to building of the company’s industrial demo plant in the Netherlands. Under his leadership Ioniqa has partnered with value chain companies such as Coca-Cola, Indorama Ventures and Unilever. Most recently, Ioniqa entered into a strategic partnership with Koch Technology Solutions to license Ioniqa’s technology to the market, branded as Denua. 

Succeeding Hooghoudt as Ioniqa’s CEO is Michiel Hoogendijk.  With a background in business development and transformation, Hoogendijk is expected to drive further growth of Ioniqa and the commercialisation of Denua. Hoogendijk is a business leader with a track record of delivering results and responsible for driving growth in chemical companies such as AkzoNobel and Avery Dennison. In order to ensure a smooth transition Hooghoudt will remain in an advisory role providing support to his successor. 

As a further part of Ioniqa’s growth, the company also announced that it has established a Board of Directors. 


Ioniqa is a clean-tech spinoff from the Eindhoven University of Technology, The Netherlands, specialised in creating value out of waste by using its proprietary circular technology. With a cost-effective process, Ioniqa is able to close the loop for plastics, starting with PET plastics. This award-winning innovation is claimed to transform all types and colours of PET waste into valuable sources for ‘virgin-quality’ recycled PET. Upcycling processes for other types of plastic are being researched and expected to be launched in the near future.
