Sulzer has partnered with Kezo, Zurich’s waste utilisation service provider, to develop and deliver a carbon capture solution for commercial validation at Kezo’s Hinwil waste-to-energy plant.

The goal is to assess integration feasibility with Kezo’s processes in preparation for its planned 2030 municipal solid waste incineration (MSWI) plant.

Sulzer’s pre-assembled modular unit will be integrated at Hinwil’s waste-to-energy plant, capturing up to 1,000 tonnes of carbon annually from the flue gas.

The captured carbon will be used by a nearby greenhouse, demonstrating efficient, circular resource use.

This is a crucial step in validating the technology’s commercial viability for Kezo’s planned new MSWI plant. Pending validation, a scaled carbon capture unit can be integrated at the new facility to capture up to 120,000 tonnes of carbon annually, supporting Switzerland’s net-zero ambitions.

The project is mainly financed by Kezo, with the Canton of Zurich contributing to the financing.

Dr Suzanne Thoma, Sulzer’s Executive Chairwoman, commented: "We are pleased to partner with Kezo, already a strong contributor to the circular economy, to advance carbon capture for waste-to-energy applications. This partnership demonstrates our shared commitment to innovation for transformative progress as we invest in tangible solutions that align environmental stewardship with economic development."

Daniel Böni, Kezo Managing Director, added: "This project shows how established industries like waste management can evolve to play a vital role in decarbonisation through technology and strategic collaboration."
