What is the Waste to Energy (WtE) process?

Waste to Energy (WtE) is a modern process that transforms non-recyclable waste into useful energy – electricity, heat, or alternative fuels. It utilizes advanced technologies such as incineration, pyrolysis, gasification, and anaerobic digestion to recover the maximum energy potential contained in waste.

Unlike traditional landfills, where waste decomposes over decades and emits methane – one of the most harmful greenhouse gases – WtE ensures a controlled and efficient conversion of waste, significantly reducing its negative environmental impact. The energy generated in this process is fed into the power grid, supports heating systems, or serves as a base for producing synthetic fuels such as hydrogen.

How does WtE work in practice?

• Incineration: The most common method, where waste is burned at high temperatures, releasing heat that is converted into steam to drive turbines generating electricity.

• Pyrolysis: A thermal process in which waste is treated in an oxygen-free environment, producing fuel oils, combustible gases, and biochar.

• Gasification: A process that converts materials into syngas, which can be used as fuel in power plants or as a raw material for chemical production.

• Anaerobic digestion: Particularly effective for organic waste such as food scraps or biomass, producing biogas and high-quality compost as byproducts.

Why is WtE better than traditional landfilling?

• Waste volume reduction: The WtE process reduces the amount of waste going to landfills by up to 90%, saving space and reducing the need for new landfill sites.

• Resource recovery: During the process, metals and other valuable materials can be recovered from the ash produced by incineration.

• Lower greenhouse gas emissions: WtE significantly reduces methane emissions, a gas over 25 times more harmful to the climate than carbon dioxide.

Waste to Energy is not only a method for efficient waste management but also a crucial component of energy transition strategies. This technology is widely adopted in cities and countries striving to achieve climate neutrality and a circular economy.
