Doppstadt has been working in environmental and recycling technology since 1965 from its Velbert, Germany, headquarters, with mobile and stationary equipment for shredding, screening, separating, and mixing materials such as waste wood, green waste, municipal solid waste, and bio-waste. The operational structure splits across Velbert (prototyping and stationary machines), Wuelfrath (service), Calbe (mobile machine production), and Wilsdruff (wet separation). ISO 9001 certification backs operations that reach more than 40 countries, with the INVENTHOR 9 shredder and mobile-modular processing systems among the headline products. Around 700 employees work at the company, which emphasises sustainable, cost-effective solutions through a global dealer network and the Doppstadt Academy training programme. The 'Best Solution. Smart Recycling.' motto captures the customer-focused, innovation-led recycling agenda.
