Less Waste, More Energy: The Curious Year 2025 at Thumaide

The answer lies in the waste itself, and it is changing. The 2025 figures from operator Ipalle tell a story of a plant adjusting to a richer fuel, of a carbon balance that doubled on paper without a single extra tonne of emissions from the chimney, and of a pilot installation on site that could shape how the sector deals with CO2 long before Brussels makes a decision that may double the cost of incineration.

There is also a new battery with a name, a fire at a cement works that forced a rapid change of plans, and a bottom line that keeps an entire network of recycling centres afloat. The full article in our updated company profile breaks down the tonnages, the energy flows and the carbon arithmetic — and explains why less waste in the furnace is not the setback it appears to be.
