The challenge: Turning solid waste into a valuable energy source

Due to changing environmental legislation and the need for alternative fuels, new designs for mechanical and biological treatment of municipal solid waste (MSW) and of commercial and industrial waste (C&I) are being developed all over the world. Refuse-derived fuel (RDF) is an alternative fuel produced by shredding, sorting and dewatering the light fraction of solid waste. The objective of this concept is to obtain high-calorific and stable material. These fuels can replace fossil fuels in many applications, such as cement kiln plants, steel furnaces, or power plants. A well-proven and highly efficient drying process turns the wet RDF into a valuable energy source for further gasification, combustion, or densification.

The solution: Advanced concepts for the production of RDF thanks to in-depth know-how, longstanding experience, and engineering competence

ANDRITZ has engineered solutions for waste-to-energy systems based on many years of experience in fuel preparation processes, such as shredding, screening, and drying. Drawing on experience from numerous installations, we improve and customize the equipment for each new application. Due to our comprehensive process capabilities, ANDRITZ can serve as a single interface for your entire RDF system, offering all process steps from one source. ANDRITZ provides state-of-the-art technologies for the treatment of all types of biomass and solid waste, and has proven solutions for further processing. ANDRITZ’s process know-how is complemented by a broad range of engineering services, from basic/detail plant and process engineering, 3D planning to electrical and control engineering. ANDRITZ project managers and technical personnel continuously prove their technological and operational competence.
