Utilisation of industrial waste
We are ready to take on full responsibility of our customers’ waste management. This also means we are designing cost-effective and environmentally sustainable solutions for our own by-product flows. We utilise by-products primarily in connection to our present activities such as: landscaping, road, open area and street construction, soil remediation, protection of ground water, the handling processes of waste and for landfill construction.
We are ready to handle the even more challenging flow of by-products and its furthere development.
Recycle by-products in a safe and environmentally friendly manner.
We monitor on a daily basis processed waste, the operating conditions for processing and treatment methods.
Slag gravel as construction material
Bottom ash that comes from incineration is refined by separating its metals for recycling. After this, slag gravel, which is comparable with crushed rock, is refined out of the mineral material which replaces natural sand and crushed rock in earthworks. Slag gravel is used as construction material for many purposes.
In the production of soil cement, a mixture of slag gravel and ash from the burning of biofuel is used as a substitute for cement, which reduces the carbon dioxide emissions of the construction industry. Finer slag gravel can also be used as a filler for pipe trenches.
Typical fractions emerging from energy production and industry which can be utilised
- The bottom and fly ash from power plants
- Steel sand, tailings, and blasting grit
- Foundry sand and dust
- Various types of sludge and dredging mass
- Fibre clay and sludge
- Various types of coarse crushed stone
