Summary
A partnership between Johnson Controls and the city of Zürich will supply green heat through a new waste incineration project spearheaded by the municipal utilities of Zürich ERZ (Entsorgung & Recycling Zurich).
The project will expand a Zürich ERZ plant with a third process line and heat recovery from flue gases. As part of the project, large-scale ammonia heat pumps will feed the recovered energy into the district heating network and provide additional heat to around 15,000 homes. With operations scheduled to start in 2027, the solution is one of the largest in Europe to use the zero Global Warming Potential (GWP) refrigerant ammonia in a heat pump application on this scale.
“As one of the largest untapped sources of energy, excess heat represents huge potential for businesses to reduce operating costs and become more resilient while meeting decarbonization targets,” says Richard Lek, Johnson Controls president, EMEA. “In 2024 alone, Johnson Controls helped cut customers’ expenses by 53% and reduce emissions by 60% compared to conventional natural gas boilers. We are proud to be partnering with ERZ on this innovative project and highlight the tremendous opportunity of waste heat sources – paving the way toward more energy-efficient and sustainable urban environments.”
