Waste Separation Saves Money
Prior to treatment or other management waste can be separated into different waste components. The separation step removes clean or lightly impacted material that can be reused at lower cost. The remaining volume of material requiring further and more costly recovery or disposal is significantly reduced.
In the next steps mineral waste components are crushed and screened. Volatile organic pollutants are collected and discharged through activated carbon.
Oil is Transformed into Carbon Dioxide and Water
Using bioremediation methods, among others, oil-impacted soils are treated in a simple way for re-use in construction, for example as road subbase. The major advantage of this process is that the contaminants are completely mineralised to carbon dioxide and water and not simply transferred from one medium to another. The energy consumption is less than for other remediation methods. The natural soil micro-organisms use hydrocarbons as a substrate for their metabolism, i.e. as a source of carbon or energy.
Soil can be treated by either static bio-piles or active soil treatment beds. In both methods the material is stockpiled and nutrients, moisture and soil structure enhancers can be added. By continuous aeration of the piles/beds a controlled transformation of contaminants to harmless end-products is ensured. In the active treatment method the soil is turned by repeated revolution.
Construction without Disruption
In our facility, contaminated mineral waste can be stockpiled prior to decisions about later recovery or disposal. If necessary, waste can be accepted immediately. Hence, delays in construction can be avoided. Also in the event of pollution incidents immediate action can be taken prior to the discussion of treatment options.
