Work initiated at WTE Plant beside Ghazipur landfill site

WTE Plant burn municipal solid waste often known as garbage or trash. To produce steam in a boiler that is used to generate electricity.

Delhi has three waste-to-energy plants in Ghazipur, Narela and Okhla. The plant in Ghazipur which was not operational for 6 months due to maintenance. Commenced its work on Wednesday, May 5.

The Lieutenant Governor, Vinai Saxena said that the WTE Plant beside the Ghazipur landfill site has become operational.

He tweeted saying that “Of the 2600 MTs of garbage generated daily in East Delhi, the plant will consume 1300 MTs per day and would reduce additional burden of fresh waste on the mounds of Ghazipur”.

In this plant, only 52.5 lakh tonnes of legacy waste have been processed so far. The plant has been utilizing 1400-1500 metric tons of municipal waste and Refuse Derived Fuel Waste (RDF) daily. In the month of April, two fire incidents were reported in the area where fresh waste was being dumped.

A senior EDMC official also commented by saying that “The Concessionaire has confirmed that the plant will begin operation from Thursday with consumption of waste in small quantities in the beginning. By May 15-20, it will become fully operational.”

What is a WTE Plant?

It facilitates the collection of waste from various landfills. And generates energy from the process of combustion of municipal solid waste. These facilities are designed to convert the remains after recycling into electricity for homes and businesses or steam for export to industries.

Waste-To-Energy plants burn municipal solid waste often known as garbage or trash. To produce steam in a boiler that is used to generate electricity. This municipal waste is a mixture of energy-rich materials such as plastics, paper, yard waste and wooden products.

Delhi has registered a jump of around 15% in the quantity of waste being dumped into the three landfill sites. As compared to the previous year, according to the government’s data.

According to reports submitted to the Union Jal Shakti Ministry and the Central Pollution Control Board. Delhi generated 10990 tonnes per day (TPD) of Municipal Solid Waste (MSW) in April 2021, on average.

Other than using fresh waste at the WTE Plant, RDF was also being used as a huge stock which had piled up at the landfill.

EDMC needs more space at the landfill to set up five pairs of trommel machines. Each having a capacity of 900 tonnes of legacy waste every day. “We have sought the finance department’s approval after which we will place it before the commissioner before inviting empanelled agencies to install and operate the machines,” the official said.

Currently, there are 26 working trommel machines at Ghazipur, including four pairs of machines with a capacity to process 50 tonnes of waste per hour. Also, through these machines, EDMC processes 2500 to 3000 tonnes of waste on a daily basis.

Impact of Waste Disposal on Public Health

Plastic is also one of the major factors in waste generation. It has various applications such as clothes, food packaging, medical, electronic, bottles, etc. It consists of synthetic polymers, and causes a significant increase in environmental pollution, leading to an environmental burden. Its effects are worrisome. It was estimated that plastic was produced 380 million tonnes in 2018. It has been predicted also by the end of 2050; oceans will be filled with plastics more than fishes. It is killing marine lives.

Abstract

AUTHOR : DR. SHRUTI

Keywords:- Waste, Disposal and Health

Worldwide waste is generated at an uncontrolled rate affecting the human and the ecosystem. Waste can be food, construction, mining, industrial, sludge, old televisions, plastic, paper, clothes, furniture, and even health waste, etc. Modernization and innovation are very hazardous, leading to destructive effects on earth-land, the air, water and of course health. As the population is increasing, the rate of generation of waste is also increasing. Ideally waste is collected and dumped into the landfills but due to the negligence of humans only this process is not being followed properly causing serious health effects followed by the affecting environment. Waste dumped into open places has many adverse effects such as climate change, depletion, unwanted chemical reactions, and even global warming due to chemical wastes which generate greenhouse gases. It causes water, soil, and land pollution. Apart from affecting the environment, it leads to an outbreak of both communicable and non-communicable diseases. Some more adverse effects are making fertile land infertile, the spread of germs, harming aquatic life due to toxicity of the water.

Effects on Health

Solid waste spreads infectious disease, making workers more vulnerable.
Hazardous wastes make children prone to polluting agents such as chemical wastes.
Wastes from industries cause negative effects on health. Water from industries causes contamination of water bodies nearby followed by affecting lives such as plants and animals depending on that water-body for their water needs.
Medical or hospital waste poses a greater risk to health. Wastes such as syringes, needles, bandages, infectious wastes, etc are responsible for creating major health hazards.
Recycling also causes health issues if not done properly. Workers working with toxic wastes are prone to infections.

Measures required for solid waste disposal

Incineration – Also known as combustion. It is the most used method for the disposal of wastes. It reduces waste volume by 85-90% by converting waste into ashes or gases. Although burning causes air pollution, filters installed in incinerators capture the gases and help to save the environment.
Recycling – As the name suggests, it involves the re-use of waste such as cans, metals, steel, bottles, etc. Separate bins are installed in many places to collect recyclable waste separately so that it can be recycled efficiently. This helps us in saving our surroundings. Awareness camps should be arranged more frequently to make the community aware of recyclable products.
Landfill – It is a low-lying area and is generally located far away from residential areas or places where there is no chance of flooding. This is a very easy method for waste disposal. This method helps to keep the animals away from the buried waste. On the other hand, we should be careful that it will not harm underground water as well.
Landfill gas – Gases such as carbon dioxide and methane helps in disposing of organic wastes. On the other hand, these gases affect our environment with a hazardous effect called Global Warming but we can control it by lowering the concentration of gases.

On the other hand, waste can be used as a resource also. We can also produce energy by breaking the wastes into substances which can be used by the public in the future such as kitchen wastes if collected properly can be used as a source of fertilizer. Another method of waste treatment called anaerobic digestion produces biogas which can also be used as fertilizer or compost.

Conclusion

Effects of this waste generation are inevitable. Government should state guidelines for proper waste disposal. Some policies need to be implemented to safeguard our environment. There is an urgent need to protect human health and the ecosystem to lead a healthy life as improper disposal of these wastes leads to an outbreak of many diseases. Recycling should be encouraged by both government and private companies leading to financial benefits also.
