Energy from Waste Solutions: Viable & Effective

Thueia Energy from Waste Solutions

Turning Waste into Power

Thueia utilizes waste-to-energy technology. This process transforms unusable or contaminated waste into clean electricity. It’s a sustainable and cost-efficient solution that reduces reliance on landfills and boosts Angola’s energy independence.

Powering Angola with Thueia

Extracting energy from waste is crucial for Angola’s energy security. In fact, it contributes roughly 3% of the country’s electricity needs. This process also aligns with the circular economy by reducing our reliance on exporting waste and allowing us to recover valuable metals and aggregates from the ashes for future recycling.

But that’s not all! The heat generated by these facilities isn’t wasted either. We capture it and use it for district heating systems and various commercial applications, maximizing efficiency and minimizing environmental impact.

Energy and biogas

We generate energy in 3 ways

Uneaten food gets a new life! Our Anaerobic Digestion facilities transform it into biogas, a clean-burning fuel.
Leftovers that can’t be recycled or reused are put to good use. We incinerate them to generate electricity.
Landfill gas gets a second chance. We capture methane from closed landfills and export it to power grids, where it becomes clean energy.

Powering Our Future While Protecting the Planet
Turning trash into treasure isn’t just a metaphor – it’s a reality with waste-to-energy technology. This process not only diverts waste from landfills but also significantly slashes CO2 emissions.

Cut Costs with Streamlined Waste Management
Leveraging our expansive infrastructure, we offer local authorities and organizations of all sizes a comprehensive waste management solution designed to boost efficiency and minimize expenses. By diverting waste from landfills, we also help you reduce your landfill tax burden.

How the process works

Food Power

Ever thrown out scraps or yard trimmings? Anaerobic digestion takes food and green waste, breaks them down in sealed chambers, and creates biogas – like methane – that fuels electricity generation. This not only harnesses waste for energy, but also prevents methane, a harmful greenhouse gas, from escaping into the atmosphere.

Waste-to-Energy

Once all recyclable and reusable materials are removed, what’s left can be burned in controlled facilities to generate energy. This process, called incineration with Refuse Derived Fuel (RDF), reduces the amount of waste going to landfills or needing export for treatment. It’s a great way to extract value from what might otherwise be trash.

Landfill Gas Capture

Even closed landfills hold a hidden resource: methane gas. This potent greenhouse gas is captured from these sites and sent to power grids for energy production. By capturing over 85% of methane from our closed landfills, we significantly reduce its impact on the environment.

Thueia’s Cutting-Edge Energy from Waste Facilities

Thueia is proud to announce two new additions to our portfolio: advanced Energy from Waste (EfW) plants!

(1) This state-of-the-art facility opened its doors in June 2023 and is already making a significant contribution. and
(2) Scheduled for launch in 2024, Protos will further expand our EfW capabilities.
