Waste to energy

Thermal energy generated during the combustion of waste to produce electricity

Thermal Treatment and Energy Recovery

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:

1. Feeding Systems: we offer fully automated and controlled feeding systems, including: Container tippers, Screw conveyors, Sludge pumps, Controlled liquid injection lances.

2. Thermal Destruction combustion is carried out with precise control of oxygen supply and temperature, tailored to the characteristics of each waste stream:

  • Rotary Kilns (Continuous – KR series)
  • Rotary Kilns (Batch – ROT series)
  • Static Furnaces for Liquids (KL series)
  • Static Furnaces for Solids (SJ, KP and KT series)

3. 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.

4. 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.

Thermal treatment furnaces by waste type

Rotary Kilns (Continuous – KR series)

600 to 4,000 kg/h

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.

Rotary Kilns (Batch – ROT series)

600 to 4,000 kg/h

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.

Static Furnaces for Liquids (KL series)

3 to 55 L/min

The KL series of static furnaces is specifically designed for efficient incineration of liquid waste, such as solvents, used oils, liquid sludges and contaminated water.

Static Furnaces for Solids

SJ, KP & KT Series

SJ Series: 5 to 20 kg/h

  • Designed for the treatment of small volumes of waste.
  • Mobile configuration for easy transport and installation.
  • Ideal for locations with limited waste management capabilities.
  • Suitable for environments such as field hospitals and camps.
  • A practical solution when no other treatment options are available.

KP Series: 30 to 50 kg/h

  • Rugged and reliable equipment for continuous use.
  • Designed for use on farms and in livestock operations.
  • Simple and easy to operate.
  • Features pre-configured operating modes.
  • Helps optimize time and make operators' work easier.

KT Series: 50 to 350 kg/h

  • Designed for easily disposable waste.
  • Suitable for materials such as paper, cardboard, wood, lightweight plastics, and municipal solid waste.
  • Capable of incinerating hospital waste and whole animal carcasses.
  • Horizontal loading system, with automatic or manual options.
  • Optimized for maximum efficiency in waste destruction.
