Waste to energy
Waste-to-energy (WtE) is the process of recovering thermal energy generated during the combustion of waste materials.
Our waste recovery plants are designed to handle a wide range of residues and are typically structured around four key stages:
• Feeding Systems: We offer fully automated and controlled feeding systems, including: Container tippers, Screw conveyors, Sludge pumps, Controlled liquid injection lances… all adapted to the specific type and condition of the waste.
• Thermal Destruction: Combustion is carried out with precise control of oxygen supply and temperature, tailored to the characteristics of each waste stream.
• Energy Recovery: The thermal energy released during combustion is recovered using: Steam, hot water, or thermal oil boilers;
ORC electrical turbines; Gas-to-air heat exchangers; Leachate quench systems, among others
• Flue Gas Cleaning: All exhaust gases are treated using physical and chemical purification systems, ensuring full compliance with the latest environmental regulations before release into the atmosphere.

Continuous Rotary Kilns
Continuous rotary kilns accept solid, pasty, and liquid waste. The rotation of the chamber mixes the waste inside the furnace, ensuring continuous and uniform incineration with even temperature distribution and sufficient residence time for efficient combustion.
The KR series is ideal for treating challenging waste types, such as:
• Industrial sludge from wastewater treatment processes, with high moisture and solid content.
• Industrial residues, such as plastics, textiles and composite materials that cannot be easily treated by other methods.
• Hazardous waste, requiring safe destruction through incineration to prevent environmental contamination.

Batch Rotary Kilns
The ROT series of batch rotary kilns is designed to handle highly heterogeneous mixtures of waste, including solids, sludges, and liquids. They are ideal for the destruction of difficult-to-treat waste requiring mixing during the combustion process. These kilns require shutdown and ash removal at the end of the operating cycle.
