H&S Plant Engineering

What H&S Plant Engineering does

H&S Anlagentechnik GmbH (operating as H&S Plant Engineering) is a privately held German industrial engineering company headquartered in Sulingen, Lower Saxony, with an R&D center in Wildau near Berlin. Founded in 1990 and operating for over 30 years, H&S specializes in plant and process engineering for the polyurethane (PU) value chain — designing and delivering storage tanks for polyol, isocyanate, resins, and pentane blowing agents; blending and dosing stations for polyol with additives, solids, and blowing agents; and chemical reactors for PU polymerization as well as chemical recycling of PU and PET waste. The company targets a diverse set of PU-processing verticals: polyurethane and raw-material producers, mattress and furniture manufacturers, household appliances, automotive, construction, and footwear.

H&S's technology differentiation lies in chemical recycling. It operates dedicated processes for converting rigid PU foam residues (glycolysis with a deamination stage that keeps primary aromatic amines below statutory limits), flexible PU foam residues (an acidolysis method preserving reactivity), post-consumer mattresses (a process yielding recovered polyol at stated production costs at least 35% below virgin polyol prices), and PET/PA into aromatic polyester polyols for insulation foams, resins, and sealants. All reactors are fully automated with electronic recipe management and batch traceability. Core hardware is paired with in-house planning/engineering (flow diagrams, layout, e-planning, permitting) and a worldwide technical service capability including remote teleservice diagnostics. The company holds German compliance credentials — WHG Section 19 specialist authorization, DIN 18800 higher-level suitability, DIN 8563 approval, and TUV fire/explosion protection — that are required to deliver chemical-process equipment into PU and refrigerant-handling industrial environments.

The business model is project-based, enterprise field sales of custom-engineered capital equipment with a managed-services tail. Revenue is generated primarily through one-time plant and equipment sales (storage, blending/dosing, reactor systems), bundled with professional planning and engineering services, and reinforced by recurring post-installation service contracts. H&S sells directly to industrial customers, working from consultation and process design through delivery, assembly, permitting, and maintenance, and exports more than 70% of its output, with a 350+-project reference base across Europe, Mexico, and other international markets. The company is bootstrapped and founder-led, with Rüdiger Schaffrath as authorized Managing Director and Mila Skokova as Deputy Managing Director Sales; no external investors, parent company, subsidiaries, or M&A activity are disclosed.

Partnerships

Three partnerships are on record, tiered core.

• Ikano IndustrycoreStrategic or Co-development Partner · 14 July 2025H&S Anlagentechnik and Ikano Industry have a long-standing partnership for PU recycling plant development. The two companies commissioned a second recycling plant in Ramos Arizpe, Mexico (July 2025), operated by Ikano's Mexican division. The plant converts post-industrial PU foam waste into high-quality recovered polyol. Earlier joint projects include the RENUVA plant in France and Retour Matras plant in the Netherlands (2022-2024).
• TB Foam SolutionscoreStrategic or Co-development Partner · 31 July 2024H&S received an order from TB Foam Solutions, a newly founded Polish subsidiary of EuroComfort Group (Germany), for a state-of-the-art tank farm for polyol and isocyanate in Leszno, Poland. The partnership also explores collaboration on developing a recycling polyol plant to boost circularity in foam production, with TB Foam Solutions implementing an 8.5 MW solar farm for CO2-free foam production.
• RetourMatrascoreStrategic or Co-development Partner · 26 September 2023H&S completed installation of a recycling facility for used mattresses at RetourMatras in the Netherlands. The plant converts 200,000 end-of-life mattresses per year into high-quality re-polyols. This circular economy initiative prevents mattress waste from being downcycled or incinerated.
