Standardized solution for local waste management
Together with our strategic partner, Woima Corporation, we deliver turnkey waste-to-energy plants based on well-proven grate combustion technology. The wasteWOIMA® solution is a pre-engineered plant with factory-fabricated, container-size modules. For the customer, this means a reliable, high-quality and cost-effective solution with simple construction and a short time to commercial operation.
The world produces about two billion tons of municipal solid waste (MSW) per year, of which more than 70% is still being landfilled, often at non-sanitary dump sites. Utilizing this locally available waste to produce electricity or heat helps mitigate its environmental impact and reduce fossil fuel dependency.

- 1A decentralized solution to unlock the potential of local waste
For small and medium-sized cities, wasteWOIMA® is the perfect solution for combining local waste treatment with low-carbon energy production. The small-scale, decentralized solution reduces the logistical challenges, costs and carbon footprint of transporting waste associated with large centralized incinerators. Generation of energy close to consumers also avoids transmission of electricity and heat over long distances, causing higher losses and often not possible.
- 2Standardized design with prefabricated modules for fast implementation
The wasteWOIMA® concept is based on a pre-engineered, modular plant with factory-fabricated container-sized modules that are easy to transport to anywhere in the world. For the customer, this unique and robust concept means a reliable, high-quality and cost-effective solution with simple and fast construction and commissioning, typically within four months from delivery. The overall time from start to commercial operation is typically between 15 and 18 months.
- 3Scalability to fit the local heat and electricity demand
A wasteWOIMA® plant can serve a waste collection area between 100,000 and 500,000 residents and sustainably convert from 30,000 up to 200,000 tons of non-recyclable waste annually into low-carbon electricity, district heating or cooling, industrial process steam or a combination of these.
The plant is scalable with one to four combustion lines, each capable of converting 30,000 to 50,000 tons of waste annually into energy:
- 3.4 MW of electricity,
- 3.0 MW of electricity and 10 MW of heat, or
- 17.9 t/h of steam at 400 ℃/40 bar,
- 4Advanced plant automation and standardized operation & maintenance
The wasteWOIMA® plant can handle a wide range of non-hazardous solid wastes and biomass fuels with calorific values between 7-22 MJ/kg and a moisture content up to 55%. The plant automatically adjusts itself to variations in fuel quality and quantity to deliver a constant energy output.
Advanced plant automation and standardized operation & maintenance ensure high plant availability, lower the staffing requirement and reduce operating costs. wasteWOIMA® plants are designed for a 30-year lifespan in the harshest of conditions.
