Waste-to-Energy Technology: How it Works and Its Advantages
Waste-to-Energy is a technologically advanced way of waste disposal is extensively known for plummeting greenhouse gases, particularly methane, by eliminating emissions from landfills. It has many advantages in saving and preserving the environment.
The advanced technology of creating energy in the form of heat and electricity by incinerating waste is referred to as Waste-to-Energy (WTE). This technologically advanced way of waste disposal is extensively known for plummeting greenhouse gases, particularly methane, by eliminating emissions from landfills.
According to NASA scientists, landfills are super-emitters of methane, a greenhouse gas that is 84 times more hazardous than CO?. Waste-to-Energy incineration is the sustainable alternative to landfills for waste disposal and it also has many other benefits. This is main attributor behind the estimated growth of the global waste-to-energy market in upcoming years.
How does the Waste-to-Energy Process Works?
First, the waste is stored in a negative pressure bunker to resist the harmful odor.
After that, the amassed waste is put into a self-sustaining incineration chamber. In the chamber, heat from the combustion boils water inside a boiler to generate steam, which turns a turbine and yield electricity.
Then, with the help of cutting-edge pollution control equipment, emissions are then cleaned, and the remaining residual material is recycled, reused or disposed of properly.
Benefits of Waste-to-Energy Technology
1. Lessens Landfill Waste
Converting waste to energy is beneficial for reducing the amount of waste entering landfills. Less waste means decreased landfills and less greenhouse gas emission.
2. Substantial Amount of Energy Generation
An amount of 550 to 700 kilowatt hours can be produced from one ton of waste, which is enough for all the electricity needs of one home for a month.
3. Helps in Reprocessing Excess Waste
Another benefit of the waste-to-energy technology is that it also reprocesses any excess metals or remains including aluminum and steel, further diminishing the amount of waste material.
4. Sustainable and Green Method
The process of the technology is itself green and eco-friendly. It employs the cutting-edge pollution control equipment to brush and filter the carbon emissions and thus restrain their expulsion into the environment.
Impact Analysis of COVID-19 on the Global Waste to Energy Market
The coronavirus outbreak has impacted the global waste-to-energy market in a negative way. During the pandemic, landfills have been expanded with the amassing of huge amount of toxic medical waste including used gloves, PPE kits, sanitizers, and other medical accessories used during the treatment of Covid-19 infected people. The waste management has been severely affected because of the restrictions on commercial activities, supply chain, and manufacturing industries. Many projects related to waste management and waste-to-energy processes were postponed during the lockdown implemented in COVID-19 pandemic.
However, governments across the world are taking various initiatives to sponsor the development of waste to energy projects. Such initiatives are expected to help the industry recover from the declining state. As per a news, in March 2020, the Indian Government granted Rs 478 crore for the research and development of waste-to-energy projects. The grant will be given to any type of waste-to-energy conversion technologies such as pyrolysis, gasification, biomethanation, combustion, or any other new technology. However, the plant must have the capacity of generating at least 5 MW power to receive the grant and there will be no maximum limit on capacity of WTE projects.
Apart from this, the leading market players are focusing on research and development, product launches, merger and acquisition, and product upgradation to sustain the growth of the market.
