Basic waste disposal operations

We implement equipment and technology in accordance with the scheme:

Reception and preliminary preparation → Heat treatment → Flower gases cleaning → Disposal of residual products

1. Waste Reception and Preliminary Preparation Shredder or Tank for Liquid Waste

1. Waste Reception and Preliminary Preparation
Shredder or Tank for Liquid Waste

Before entering the main thermal treatment equipment, waste undergoes preparation:

  1. Sorting — Large or non-combustible elements are removed
  2. Shredding — Solid waste is crushed for uniform combustion
  3. Dosing — Waste is fed into the furnace in strictly measured quantities to maintain stable combustion

For liquid waste, tanks, pumps, and spray nozzles are used for atomization.

2. Thermal Waste Treatment
Waste Incineration Furnace

The key process occurs in an incineration furnace or reactor:

  1. Waste is fed into a high-temperature zone
  2. Under high temperatures, organic substances decompose into simple molecules — carbon dioxide, water, and inert ash
  3. For gaseous and liquid fractions, a system of nozzles or gasifiers is used
  4. Air and gas are supplied to gas burners to stabilize temperature

Furnace Types:

  • Rotary kilns — Versatile for various waste types
  • Stationary multi-chamber furnaces — For complex or highly hazardous waste
  • Pyrolysis units — For waste with high organic content
  • Cyclone furnaces — For liquid waste

Gases exiting the afterburner are cooled to 200 °C in an air- or water-cooled condenser.

3. Flue Gas Purification

Post-combustion, flue gases are purified to safe standards:

  1. Gases pass through a cooling system to reduce temperature and prevent dioxin formation
  2. Scrubbers, filters, or electrostatic precipitators remove ash, dust, and heavy metals
  3. Catalytic neutralizers may break down residual harmful compounds

This is a critical stage ensuring environmental safety and compliance with emission standards.

4. Residual Product Disposal

After thermal treatment, ash or slag remains, typically amounting to 5–10% of the original waste volume. These residues undergo conditioning and may be landfilled or repurposed, e.g., as construction material.

Some complexes utilize heat recovery — hot gases and steam can heat water or generate electricity.
