Articles and case studies
See specific examples of our work. In this section you will find real projects we have carried out for our customers – from solving technical challenges to deploying bespoke machines. We show how our machines and technologies help to optimise processes, save resources and bring workable solutions into practice.
Mechanical processing of automotive manufacturing waste prior to material recycling
Mechanical pre-processing of automotive production waste can significantly simplify downstream metal separation and plastic recycling. In this technical case study, we analyse the processing of a mixed waste stream containing polyamide components, steel inserts and springs. We evaluate how the individual components behave during shredding and demonstrate the conditions under which the material can be effectively prepared for magnetic separation.
Shredding aluminium offcuts | Reducing the volume of metal waste
Aluminium stamping offcuts often have a very low bulk density. Long strips tend to become entangled inside containers, creating large voids and making storage and transport inefficient. During a shredding trial, we evaluated how the material changed after processing in a twin-shaft shredder. The result was short, compact fragments with a bulk density of approximately 590 kg/m³.
Shredding steel swarf at the KIA Slovakia engine production facility
Kia Slovakia's engine plant in Žilina is an example of highly automated and precise production, where an effective solution for processing technological waste becomes a key element of operational stability. The article shows how centralized crushing of steel chips in both continuous and single-shift operation contributes to higher safety, lower costs, better logistics and sustainable resource management within the Hyundai Motor Group.
How much plastic does a passenger car contain, and why is it so difficult to recycle?
A modern passenger car can contain up to 300 kilograms of plastic. Recycling these materials, however, is not easy. Different types of plastics are often combined with metal components and may need to be transported over considerable distances for further processing. This is why shredding plays an important role in reducing logistics costs and improving recycling efficiency. In a CASTULIK application trial, the DX160 twin-shaft shredder successfully processed one of the more challenging plastic components found in a vehicle – a plastic fuel tank.
Crushing the costs of hazardous waste handling
Company DETOX has long been one of the most reliable providers of hazardous waste collection and processing services in Slovakia. In 2023, the company expanded its Trnava facility with a twin-shaft shredder DX160/600 (18.5 kW) – their third CASTULIK shredder purchased since 2003.
