The global waste-to-energy market size was valued at USD 43.76 billion in 2024 and is estimated to reach USD 76.67 billion by 2033, growing at a CAGR of 6.43% during the forecast period (2025–2033). As global energy consumption rises, the need for renewable and alternative energy sources is intensifying. WTE offers a renewable energy solution by converting waste into power, reducing dependence on fossil fuels, and promoting energy security.
Waste-to-energy (WTE) is a process that involves converting non-recyclable waste materials into usable energy, typically in the form of electricity or heat. This process helps manage waste while also generating renewable energy. WTE technologies can include various methods such as incineration, gasification, pyrolysis, and anaerobic digestion.
In an incineration-based WTE facility, for example, waste is burned at high temperatures to produce steam, which then drives turbines to generate electricity. Similarly, gasification and pyrolysis convert waste into synthetic gas or bio-oil, which can be used as fuel for power generation. Anaerobic digestion is typically used for organic waste, where microbes break down waste in an oxygen-free environment to produce biogas.
Rising waste generation and landfill overflow
The increasing global population and rapid urbanization are contributing to a significant rise in waste generation, creating a pressing need for effective waste management solutions. Landfills are quickly reaching their capacity, causing environmental concerns and leading governments to explore alternative methods of waste disposal. Waste-to-energy (WTE) technologies offer a sustainable solution by converting waste into electricity, reducing the need for landfills while generating power.
For example, in Japan, one of the most waste-conscious countries, the government has implemented widespread WTE plants to handle its waste efficiently. As of 2021, Japan operated over 1,000 WTE facilities, successfully processing millions of tons of waste annually. In Europe, cities like Amsterdam and London are increasingly relying on WTE plants to tackle waste overflow, with the Netherlands alone converting around 5.5 million tons of waste into energy each year.
These efforts highlight how WTE technologies are integral in managing waste while supporting energy needs.
High capital investment
One of the significant barriers to the widespread adoption of waste-to-energy (WTE) technologies is the high capital investment required for setting up and maintaining the infrastructure. Building WTE plants involves substantial costs for advanced technologies, land acquisition, regulatory compliance, and ongoing operational expenses.
On average, the cost of constructing a WTE facility can range from $200 million to $1 billion, depending on the plant’s size and the technology used. This high initial investment can be a challenge, especially for governments or companies in developing countries or regions with limited financial resources.
Moreover, the long payback period for these projects can deter investors, limiting the market’s growth potential. Despite these challenges, the long-term benefits of WTE, including energy generation and reduced landfill use, can make it a viable option in the future.
Technological advancements in WTE technology
Advancements in waste-to-energy (WTE) technologies are creating significant opportunities for market growth. Innovations, such as gasification and anaerobic digestion, are enhancing the efficiency and environmental performance of WTE plants. These technologies allow for cleaner, more effective waste conversion into energy, reducing emissions and increasing energy output.
For example, Covanta, a leading WTE provider, has adopted advanced gasification methods in its plants, which use high temperatures to convert waste into synthetic gas, improving energy efficiency while reducing air pollution. In Sweden, the Gasification-based Biofuel plant in Västervik is capable of converting household waste into electricity and district heating with minimal environmental impact.
Moreover, smart grid integration is enabling WTE plants to optimize energy production based on demand, reducing waste and increasing profitability. As these technologies evolve, WTE will become a more cost-effective and sustainable solution for managing waste and generating renewable energy globally.

Thermochemical technology dominates the global waste-to-energy market due to its ability to efficiently convert various types of waste into energy through processes such as combustion, pyrolysis, and gasification. This technology is particularly effective for high-calorific-value waste, such as municipal solid waste and industrial byproducts.
Thermochemical methods are widely used for large-scale energy generation, offering high efficiency and energy output. With increasing energy demands and the push for sustainable waste management solutions, thermochemical technology remains the dominant choice in waste-to-energy applications, driving its growth in both developed and emerging markets.
Municipal Solid Waste (MSW) is the dominant waste type in the waste-to-energy market due to the large volumes generated globally in urban areas. MSW consists of everyday household waste, such as paper, plastics, and organic materials, which can be effectively converted into energy using both thermochemical and biochemical technologies.
The high disposal rate of MSW, coupled with the need for sustainable waste management solutions, drives the adoption of waste-to-energy technologies. As urbanization grows and landfills become less viable, utilizing MSW for energy production is seen as a crucial step in managing waste sustainably.
Electricity generation is the dominant application segment in the waste-to-energy market, as it offers a reliable and scalable solution for energy production. The process involves converting waste into electricity, which can then be fed into the grid or used locally. This application is particularly significant in regions with high population density and waste generation, where energy demands are rising.
The ability to generate baseload power from waste reduces reliance on fossil fuels. It supports the transition to cleaner energy sources, making electricity production a key focus in the growth of waste-to-energy systems globally.
China is leading the charge with one of the largest WTE markets globally. In 2021, China’s WTE plants processed over 50 million tons of waste, and the country has set ambitious goals to expand its WTE capacity further. For example, the Shanghai Environmental Energy Industry Park processes 1.5 million tons of waste annually, converting it into electricity and heating for surrounding areas.
In India, WTE adoption is also growing. The Okhla Waste-to-Energy Plant in Delhi, which began operations in 2022, is one of the largest in the country. This plant processes over 1,500 tons of waste daily, generating 12 MW of electricity, addressing the country’s waste management crisis.
With the Asia-Pacific region’s growing commitment to sustainable energy solutions and waste management, the WTE market is poised for significant expansion, making it a key player in the global market.
