Energy recovery from waste: How waste can be transformed into power

Waste-to-Energy (WtE) or energy recovery from waste is the conversion of non-recyclable waste materials into useable heat, electricity, or fuel through a variety of processes. It recovers waste that would normally pile up in a landfill and uses it for meaningful purposes.

Indeed, landfills accumulate leachate, pests, and toxic gases; and are an important source of greenhouse gas emissions (GHG). Using low-carbon technologies to treat waste like REVALUO can help mitigate climate change at the same time it boosts energy savings and moves towards a circular economy.

But, how does it work?

Recovering energy from waste using REVALUO

REVALUO is our low-carbon WtE system that recovers energy from plastics, rubber, and organic waste. It transforms it into fuel and electric power using a thermochemical treatment: the THERMOLYSIS.

The THERMOLYSIS is a form to break down matter using heat. It heats pellets at temperatures ranging from 650°C and 1200°C in the absence of oxygen and decomposes them into different forms: liquid, solid, and gas. At the same time, it uses the same heat in the process to generate electric power through a steam boiler.

As a result, we get Bunker fuel, charcoal, synthetic gas, and electricity.

¿How many homes can a 2MWh thermolysis plant supply?

A 2MWh thermolysis plant can supply approximately 5,880 households at a 3.4 Kw/h consumption rate.

Note that the 2MWh is the smallest module. Our plants use modular joint systems, thus we can add on new modules as required.

In addition to that, the energy we produce is completely clean – we produce less than 4g/h CO2 per tonne of waste. REVALUO does not burn waste*.

What type of waste can be recovered using REVALUO?

Plastic (not PVC).

Used tires.

Rubber.

Leachate.

Organic matter and biomass waste.

Others: hazardous waste, medical waste, industrial waste, and MSW.
