(NL9202033-A)      Treatment of incineration residues involves treating the residues with air contg. 0,.1-100% by vol. CO2.    Pref. treatment is carried out at a temp. from ambient temp. - 200 deg. C under a pressure from atmos. - 10 bar overpressure. More pref. this method is carried out with a gas contg. 5 - 20% by vol. CO2 at a temp. of not more than 100 deg. C and an overpressure of not more than 1 atmos.. Microorganisms are added during treatment or before treatment with CO2.    USE/ADVANTAGE -   For treatment of incineration residues produced by e.g. incineration of domestic waste. Incineration residues produced by e.g. incineration of domestic waste. Incineration residues can be used as absorption material for CO2 removal from CO2 rich off gases e.g. flue gas, biogas, disposal site gas or off-gas of composting plants (claimed). The CO2 enriched air treatment of WIP slags substantially reduces the leaching concns. e.g. Cu, Al, Mo by e.g. 50% in comparison to treatment with air. The decrease of the pH to 8 can result in the growth of microorganisms which are beneficial for the degradation of residual (unincinerated) organic matter.
