Press release

Vaasa, Finland & Shanghai, China –November 2023

Shanghai SUS ENVIRONMENT Co.,LTD (SUS) and WOIMA Finland Oy (WOIMA) have signed an agreement to increase the market reach of the modular wasteWOIMA® waste-to-energy solution. The parties will develop new WtE projects and target markets currently out of reach to both parties.

The modular wasteWOIMA® WtE plant is a unique pre-engineered and prefabricated small-to-medium-scale solution allowing fast project deployment. It is easily scalable for projects with 25,000 to 200,000 tons of non-recyclable waste annually. The workshop-fabricated and pre-assembled modules guarantee a high-quality, cost-effective and on-time delivery, as well as fast construction time on site. Together these offer significant project risk reduction.

The plant utilizes robust grate combustion technology to safely treat a wide range of solid waste fuels while complying with the most stringent environmental standards. Advanced plant automation and standardized maintenance ensure long lifespan, high plant reliability and low operating costs.

The wasteWOIMA® plant has a large number of applications ranging from stand-alone industrial steam generation to grid-connected CHP plant to decentralized waste management and power generation solution for larger cities. Our carbon capture solution enables the delivery of carbon-neutral, or even carbon negative, WtE projects. These all benefit from the same modular and standardized design and engineering, manufacturing processes and supply chain.

Mr Kinnunen and Mr Zhan signing the MOA as Chairman’s of SUS and WOIMA Mr Long and Mr Manner act as Witness

Dr. Long Jisheng, Chairman, SUS: “SUS has been developing waste incineration power generation technology in China for almost two decades. With this vast experiences and together with WOIMA we shall work to address the solid waste to energy issues, create innovative solid waste management strategies, and make a meaningful contribution to global environmental protection especially in the small and medium scale projects globally”.

Henri Kinnunen, CEO, WOIMA: “Waste generation is a growing challenge around the globe, especially in the emerging markets that also lack a dependable power generation. SUS, with its proven track record as one of the biggest players in the WtE market, offers an exciting opportunity to reach new markets and customers. The strengths of both companies complement each other perfectly.”
