Incineration

Source: TH

Context: Spill-free trucks carrying 337 tonnes of chemical waste from the Bhopal gas tragedy are set to reach Pithampur, where the waste will be incinerated within three to nine months.

About Incineration:

• What it is: Incineration is the controlled combustion of waste in high-temperature furnaces to reduce volume, neutralize hazardous materials, and recover energy.

• Procedure:

• Combustion: Waste is burned at temperatures exceeding 850°C for complete destruction of toxins. Energy Recovery: Heat from combustion generates steam, which powers turbines for electricity production. Exhaust Gas Cleaning: Advanced systems like scrubbers and bag house filters remove harmful pollutants from emissions. Ash Residue Handling: Bottom ash is recycled or landfilled, while fly ash is treated with chemicals before disposal.

• Ash Residue Handling: Bottom ash is recycled or landfilled, while fly ash is treated with chemicals before disposal.

• Advantages:

• Energy Generation: Produces electricity and heat from waste combustion. Space-Saving: Reduces landfill dependency in densely populated areas. Pollution Control: Modern systems ensure minimal environmental impact by capturing emissions. Resource Recovery: Produces materials like paving bricks and activated carbon. Safe Disposal: Effectively neutralizes hazardous materials.

• Limitations:

• Harmful Emissions: Releases dioxins, furans, and other toxins if not properly maintained. Health Risks: Linked to respiratory issues and carcinogenic effects near poorly managed plants. Air and Water Pollution: Residual ash and flue gases can contaminate the environment. High Costs: Advanced incinerators require significant investment and maintenance. Inefficiency with Moisture: Wet waste in India reduces calorific efficiency.
