Cleaning up construction site accidents – naturally
Despite all the precautions, oil and fuel spills can still occur on construction sites. In its efforts to manage such accidents and mishaps, Implenia Sweden has been testing the innovative absorption agent DissOil for a number of years. DissOil is made 100 percent from cork, a renewable raw material produced as a waste product of, for example, bottle cork production.
Implenia is the second company in the world to test DissOil, and the first in the construction industry. DissOil granules are scattered on the spilled liquid and start absorbing greasy components within seconds. It absorbs up to ten times its own weight of grease. but does not take in water. In fact DissOil continues to float on the surface of water even when completely soaked in oil.
Microbes within DissOil use enzymes to break the oil down into harmless components. The degradation process is activated by water – for example by soil moisture, dew or rain. After one to three weeks the work is done. The soil does not need any further treatment after cleaning.
Johan Asplund, Project Manager at Implenia Sweden, is impressed by the new cleaner. “We’re very pleased with the positive test results.” When the process is over, all that's left is pure cork – free of chemicals and other additional substances – making it a perfect alternative to conventional absorbents.
- Crustacean purificationImplenia Sweden is testing a new technology designed to clean the waste water produced on construction sites more effectively. The clever part is that the key substance used to remove pollutants is a simple by-product of food production.
- A bridge joins the circular economyRecycling is all the rage of course, but when it’s not just individual materials and components but an entire major structure being repurposed, that’s something special. Implenia has done precisely this, working with partner companies to dismantle an old bridge in Norway and rebuild it in another part of the country.
- Closing material cycles on siteImplenia has set ambitious waste and recycling goals for 2025. It is making a huge effort to avoid construction waste and to reuse and recycle materials in a circular economy. Two examples show that Implenia is heading in the right direction.
