Centro Uno Entered Ramp-Up Phase

The first results are very promising.

It's a key milestone for Selfrag: Centro Uno, its innovative waste-to-value facility in Full-Reuenthal, Switzerland, has become operational and successfully entered the ramp-up phase. The team worked hard for this and the first results are very promising. Centro Uno has already proven that its capabilities will exceed the competition by far.

Unmatched recovery rates

Centro Uno uses patented technology to upcycle resources like metals and minerals from incinerator bottom ash (IBA). During the first few weeks of operation the plant delivered already industry-leading recovery rates. Overall, "a total of 13.3% metals, 6.5% iron oxide, 23-28% minerals and 3% unburned materials have been recovered" from IBA. These rates are approximately 3 times better than those obtained with conventional technologies.

Full capacity by July

The construction of Centro Uno started in January 2022 and was completed by the end of that year. With its operational capacity expected to reach 100% by July 13, Centro Uno will have a throughput of 35,000 tons of incinerator bottom ash annually. The slag is provided by three incinerators in the region. "50% of the material is set to be recovered in the process."

Game-changing technology

Centro Uno combines the SELFRAG 2.0 technology with density separation, washing and screening. The multi-step process includes a unique additional treatment of the mineral fraction using high-voltage pulses, which further reduces heavy metal content.

Reducing waste and CO2

The waste-to-value process reduces IBA ending up in landfills by 50% while allowing valuable materials to re-enter the economy. Selfrag anticipates recovering approximately between 300 and 450 kg of CO2 per ton of slag treated.
