Impacts of waste water sludge and cellulose addition on stabilization of municipal solid waste incineration bottom ash

The objective was to test if the carbon dioxide released through the microbial respiration, enhanced by the adding of external organic matter in the bottom ash, could be absorbed by the ashes and thus improve the carbonation process. Several percentages of waste water sewage sludge and cellulose were mixed to freshly quenched and carbonated bottom ash. The results showed a high CO2 absorbing capacity by the BA but a high heavy metals leaching capacity
