Waste to Energy plant- the solution to our waste management problem?

Waste to Energy plant


Although there are many people who still don’t believe in the future of renewable energy, the truth is that it has already arrived. Countries all over the world are investing in wind turbines, solar panels, and other types of green energy solutions to help reduce pollution of the environment.

But what about waste management? That’s a problem that affects every country on earth, and one that is becoming increasingly difficult to solve. Fortunately, there is a new type of waste management solution that is starting to gain popularity – waste to energy plant that turns garbage into electricity, this can help reduce our reliance on fossil fuels and mitigate climate change.

But is this really the best way to handle our waste? Or are there better options available? Join me as we explore the pros and cons of waste-to-energy plants and consider how we can best move forward in terms of waste management.

Why do we need a better waste management solution?

Globally, we generate about two billion tons of household waste each year, with high-income countries producing disproportionately large amounts compared to their populations. 37% of worldwide waste goes to landfills, contaminating groundwater and releasing methane. Only around a quarter of the world’s waste is recycled or composted. Many countries lack waste collection services; thus, their garbage is usually found in rivers, which are a major source of ocean plastic.

Every year, over one billion tons of waste are openly burned to get rid of as much trash as possible as quickly as feasible. Global warming is mainly caused by the open-air incineration of all sorts of waste. We require a more efficient waste management system for all these reasons. Waste-to-energy plants can be an approach to the solution.

How do Waste to Energy Plants Work?

One of the most promising alternatives of energy generation is waste-to-energy facilities. These facilities generate energy by burning garbage in a regulated manner. At first, the waste is dumped into a large pit and then fed into the furnaces. They burn extremely hot, reducing waste in minutes. The heat from the fires generates steam, which is used to power turbines. Steam can also be utilized to generate heat. Bottom ash is the 10% that does not burn, and metals can be recovered from it. The remainder might then be used for construction. As a result, the method reduces waste, generates energy, and a portion of the residue can even be recycled.

The waste that is burned can be anything from paper, electronics, kitchen trash, and plastic to tires and medical waste. The basic process of waste-to-energy plants is quite like that of a coal power plant, except for the fact that garbage is used instead of coal.

What are the Benefits of Using a Waste to Energy Plant?

One of the major benefits of waste to energy plants is that they help reduce waste by converting waste materials into usable energy. This not only helps decrease our reliance on traditional fossil fuels but also reduces the amount of waste that ends up in landfills and pollutes our environment.

Additionally, waste-to-energy plants reduce our carbon footprint and combat the effects of climate change.

Finally, these plants often recycle a portion of waste residues, further reducing waste and helping to conserve resources.

Overall, waste-to-energy plants are an effective solution for addressing our waste management challenges, while also promoting sustainable energy production and protecting our environment.

What are the drawbacks of a waste-to-energy plant?

One of the main drawbacks of waste to energy plants is the cost. These facilities require highly sophisticated technology and trained staff, which can be quite expensive to implement and maintain.

Additionally, waste to energy plants can have negative environmental impacts, especially if they are not properly managed and regulated. For example, waste to energy plants that burn waste can emit harmful pollutants such as fly ash, which can cause respiratory issues and other health problems for people living nearby. They also produce a lot of CO2s: around 52 million tons per year only in the EU where the world’s large number of waste energy plants are situated. That’s the equivalent of 430,000 autos driving a million kilometers each.

Another drawback of waste to energy plants is that they only generate not a significant amount of electricity compared with other power plants such as coal or natural gas. This means that waste to energy plants is not as efficient in terms of power generation and thus, can be less cost-effective in the long run. Waste with less calorific value can cause the plant to burn more fuel to produce electricity which makes the whole plant inefficient. Calorific value refers to how easily a substance burns. So, even the nature of the waste influences the overall efficiency of the plant.

By classifying this energy as renewable, funds could be diverted away from more environmentally friendly waste management systems such as recycling. It is surely not a renewable energy source. It may create confusion among people concerning the environment. Regardless of how much energy is produced, it is by far not the cleanest way to handle the waste.

For these reasons, waste-to-energy plants should be used only in limited circumstances as a last resort and not as the primary waste management method.

Is it feasible to build a waste-to-energy facility in any country?

While waste-to-energy plants have emerged as a popular solution to waste management problems in many developed countries, their effectiveness is contingent on the nature of waste generated in that location. Factors such as waste composition and energy generation requirements can significantly impact the efficiency of waste-to-energy facilities. Furthermore, these factors must be considered alongside social and economic considerations, such as the waste management infrastructure already in place and public support for waste-to-energy plants initiatives.

Japan has over 1200 waste-to-energy plants, with China having the largest facility in the world with over 300. Currently, the EU has around 500 waste-to-energy plants. waste-to-energy plants  can also be found in the United States, India, Taiwan, Singapore, and many parts of the world. Ethiopia’s Addis Ababa features the continent’s first waste-to-energy plant. Some companies experienced in waste-to-energy plants team up with many countries to install similar facilities and enhance business. For example, the Chinese company, China Machinery Engineering Corporation (CMEC) has partnered with Bangladesh Govt. to plant and to operate waste-to-energy facilities near the outskirts of Dhaka, for the next 25 years.

Given the many challenges associated with waste-to-energy plants, it is important to carefully evaluate whether such a facility would be feasible in a particular country. Ultimately, the success of waste-to-energy plants depends on how well they can integrate into existing waste management frameworks, and proper waste segregation to fuel the waste-to-energy plants, and contribute to a sustainable waste management strategy for the country. While waste-to-energy may not be the right solution for all countries, it is certainly an important tool to consider as part of a comprehensive waste management strategy.


In conclusion, waste-to-energy plants can be a viable solution to waste management problems in certain circumstances. However, they are not without challenges and must be carefully evaluated before being implemented. When done so, waste-to-energy plants can contribute to a more sustainable waste management strategy for a country. Therefore, it is essential for governments to take these factors into consideration when deciding whether to build waste-to-energy facilities in their jurisdictions.
