Switzerland: Selfrag will install its first commercial system using electrodynamic fragmentation to recycle incinerator slag at a SAIDEF incinerator in Posieux, Canton Fribourg. The system will be ready for operation at the beginning of 2016. SAIDEF expects to increase recovery of ferrous and non-ferrous metals by more than 100% and reduce landfill requirements by up to 30%.

"We can double our recovery, especially for non-ferrous metals. The recovered metals are cleaner and will generate a higher sales price. Additionally, about 5% to 10% of the total slag volume is completely cleaned, fulfilling stringent Swiss regulations on inert fractions and can be potentially used as aggregates in road construction, which opens up another income source. The metal recycling, together with the decontamination of the remaining material, will reduce the material to be landfilled by 20 - 30%, leading to a cost saving of Euro42/t. There is an additional benefit through the reduction of CO₂ emissions from the material incineration process, a mandatory requirement in Switzerland from 2020," said Albert Bachmann, CEO of SAIDEF.

The system in Posieux, with a capacity of 3t/hr, will be installed in partnership with Frei Fördertechnik.
