Czech engineering SME specialising in advanced polymer recycling and smart industrial process retrofitting for the circular economy.
HTT Engineering is a Czech engineering SME based in Brno working at the applied end of polymer processing and industrial sustainability — translating research into demonstration-ready solutions. In the POLYNSPIRE project they contributed to advanced plastic recycling technologies, including vitrimer-based polymers, microwave-assisted processing, and magnetic catalyst approaches targeting automotive-grade polyamides, polyurethanes, and polyolefins. In RETROFEED they shifted toward the broader challenge of retrofitting existing process industry plants to operate with alternative feedstocks and reduced resource consumption, combining advanced modelling with monitoring and control systems. Their profile is that of a specialist technical partner capable of bridging chemistry, materials engineering, and industrial process design within large European consortia.
POLYNSPIRE focused on recycling polyamide, polyurethane, and polyolefin streams using vitrimer chemistry, microwave treatment, and magnetic catalysts targeting the chemical and automotive industries.
RETROFEED involved implementing a smart retrofitting framework for process industry plants to improve energy and resource efficiency while integrating alternative and bio-based feedstocks.
RETROFEED listed monitoring and control systems and advanced modelling and simulation among its core technical contributions.
RETROFEED explicitly addressed circular economy and bioeconomy principles as framing conditions for industrial process redesign.
HTT Engineering's early H2020 work centred on material-specific recycling: which chemical routes and physical processes can recover value from specific polymer types like polyamide or polyurethane, with techniques such as microwave treatment and magnetic catalysts. By 2019 their focus had broadened from individual materials to whole industrial systems — how to retrofit entire process plants, model complex operations, and integrate monitoring systems for resource efficiency across the process industry. The trajectory is from specialist polymer chemistry toward applied industrial sustainability engineering, with each step keeping the same underlying concern (reducing waste and resource use) but zooming out in scope.
HTT Engineering appears to be broadening from material-level recycling expertise toward system-level industrial transformation, making them increasingly relevant to companies seeking to redesign process plants for sustainability rather than just improve a single recycling step.
HTT Engineering has never led an H2020 project — both participations are as a consortium partner, consistent with a specialist SME that brings specific technical competence rather than project management infrastructure. Both projects are large Innovation Actions within the SPIRE process industry community, which routinely involves 15–25 partners, explaining their unusually high network count of 41 partners from just two projects. This pattern suggests they are comfortable working inside complex multi-partner consortia and are likely sought out for a defined technical contribution rather than for coordination capacity.
HTT Engineering has accumulated 41 consortium partners across 15 countries from just two projects — a high density that reflects the large-scale Innovation Actions they joined under the SPIRE process industry roadmap. Their network spans a broad cross-section of European chemical, manufacturing, and research communities, despite the company's small size.
HTT Engineering occupies a specific niche as a Czech engineering SME that combines polymer materials expertise with industrial process engineering — a combination rarely found in a single small company. Their alignment with the SPIRE process industry community gives them credibility with large European chemical and manufacturing players. For consortium builders, they offer a cost-effective specialist partner with demonstrated ability to operate inside complex multi-national projects, particularly where recycling technology or industrial retrofitting is a defined work package.
