A process for the recovery of bottom ash is characterized by shredding and physical separation phases. The bottom ash undergoes an oxidation treatment of the amphoteric metals contained therein. After the process the treated bottom ash can be employed as mineral Nowadays more efforts towards sustainability are required from the concrete industry. Replacing traditional aggregates by recycled bottom ash (BA) from municipal solid waste incineration can contribute to this goal. Until now only partial replacement has been considered to keep the concrete workability strength and durability under control. In this research the feasibility of a full

The allowable limits of chloride in the fly ash and bottom ash were found to be 1.75 and 3.50 respectively. The results indicate that cement production can be a feasible alternative for MSWI ash management. It is also evident that the addition of either fly ash or bottom ash did not have any effect on the compressive strength of the clinker. The total amounts of MSW treated by these incineration plants were 6 million tons per year and 1.1 million tons of bottom ash (accounting for 18.3 of treated MSW) and 300 000 tons of fly ash stabilized products (accounting for 5 of treated MSW) were generated 1 . At present most of the incineration bottom ash is reused in civil

Characteristics of incineration ash for sustainable

Municipal solid waste incineration (MSWI) generates bottom ash fly ash (FA) and air pollution control () residues as by-products. FA and residues are considered hazardous due to the presence of soluble salts and a high concentration of heavy metals and they should be appropriately treated before disposal. Physicochemical characterization using inductively coupled plasma mass The allowable limits of chloride in the fly ash and bottom ash were found to be 1.75 and 3.50 respectively. The results indicate that cement production can be a feasible alternative for MSWI ash management. It is also evident that the addition of either fly ash or bottom ash did not have any effect on the compressive strength of the clinker.

Furthermore alkali treatment enhances pozzolanic properties of IBA and the resulting alkali-treated IBA possessed pozzolanic reactivity similar to coal fly ash. The strength activity indices (SAI) of the resulting alkali-treated IBA blended cement mortars were above valorization from municipal solid waste incineration (MSWI) for its use as a sole precursor for developing alkali-activated binders (AABs). Alkali-activated weathered bottom ash binders (AA-WBA) were formulated with a liquid-to-solid ratio of 1.0 and using sodium silicate (80 wt. )

At present most of the incineration bottom ash is reused in civil municipal solid waste incineration bottom ash. Previous research shows1 by using specific dry and wet treatment steps the large size bottom ash fraction > 2/3-16 mm is upgraded to a high potential aggregate. This aggregate can be used as gravel replacement in concrete and is in accordance with EU regulatory standards. However

The ash must however be very fine-grained so the fine-grinding increases the treatment costs. The production possibilities of the hydrogen gas contained by waste incineration bottom ash has also been studied in Japan (Saffarzadeh ym. 2016). The method provides one potential option for converting bottom ash into a resource with a higher value. treated Municipal Solid Waste Incineration (MSWI) bottom ash which is rich in silica and alumina could be a potential alternative cement replacement in concrete production 8 . Combining fly ash and MSWI bottom ash as a precursor in geopolymer production was also proven to improve the properties of the resulting geopolymer concrete 10 .
