Optimized process for 50 percent reduction of landfill mass
A 50 percent reduction in landfill mass and a significant reduction in the CO2 footprint: SELFRAG presented an optimized process for the processing of waste slag at the Swiss Green Economic Symposium on September 1, 2020 in Winterthur.
The SELFRAG process is based on an energy-efficient and at the same time economical comminution method. The components trapped in the slag are released precisely along the material boundaries by means of high-voltage pulses. In combination with known sorting methods, a sustainable and efficient overall system for the recovery of metals and mineral fractions is created.
At least 50 percent reduction in landfill mass
In addition to the very high metal recovery, SELFRAG's technology also impresses with a substantial reduction in landfill volume. At least half of the slag can be returned to the material cycle - a significant contribution to the circular economy. The recovered mineral components are reused as additives in the cement and construction industries. This conserves landfill sites reduces landfill costs and leads to significant CO2 savings.
Marked reduction of the CO2 footprint
The SELFRAG plants are built on site or in the immediate vicinity of the waste incineration plants. This relieves the road network. Local jobs are created and long transport routes for the slag are avoided - a further contribution to reducing the CO2 footprint.
Flexible and economically advantageous
SELFRAG finances, builds and operates plants in Switzerland. Frederic von der Weid, CEO of SELFRAG, explains: "With our solution, there is no need for costly and unnecessary construction measures, such as converting a kiln line to dry discharge or investing in our own slag processing plant. As the operator of the plants, we assume responsibility for the treatment process and guarantee compliance with all legal requirements."
