- Joint venture for innovative plastics recycling
Sika and Sulzer have signed a memorandum of understanding to establish a joint venture to advance plastics recycling in the construction industry. The aim is to combine the strengths of both companies: Sika's extensive expertise in polymer applications and high-performance building materials and Sulzer's leading process knowledge in chemical recycling. The joint venture, based in the Zurich area, will be founded as an independent company, with each partner holding a 50 percent stake. Operational activities will commence in the second half of 2025 with pilot projects in Germany, Austria and Switzerland.
Approximately two million tons of plastic waste are generated in the European construction industry alone each year. Currently, recycling these complex materials is highly fragmented, technically demanding, and often inefficient. As a result, the majority of construction plastics are disposed by the end of their lifecycle, since existing mechanical recycling methods produce low-quality materials that are not suitable for reuse.
Partnering for sustainable transformation of the construction industryWith this joint venture, Sika and Sulzer are developing a system for the collection, processing and reuse of construction plastics using mechanical and chemical processes.

The joint venture between Sika and Sulzer will close gaps in the value chain of the construction industry, and offer customers a comprehensive, cost-efficient service package. The offering will be complemented by local partners, such as logistics and recycling companies, which will be integrated into specific process steps. Recycled materials will thus be reincorporated into the manufacturing process.
