This study replaced natural aggregate with a fine aggregate of washed municipal solid waste incinerator bottom ash (WMSWIBA) in the production of compressed concrete paving units to increase the applications of WMSWIBA. The cement-aggregate ratios investigated were 0.1, 0.2, 0.3, 0.4 and 0.5, and the water-cement ratios were 0.20, 0.25 and 0.30. The results showed that the coefficient of permeability of the compressed concrete paving units was less than 2.66×10-5 cm/sec, the water absorption was 13.55~4.75%, the porosity was 8.05~1.62%, the compressive strength was 12.3~48.5 MPa, the ultrasonic pulse velocity was 1521~3059 m/sec, and the attrition volume loss was 117.7~16.0 cm3/50 cm2. The results suggested that the compressive strength and ultrasonic pulse velocity increase with the cement-aggregate ratio, whereas the attrition loss decreases.

This study aims to evaluate the potential of incorporating fly ash (FA) and municipal solid waste incinerator bottom ash (MIBA) as a partial substitute of cement in the production of self-compacting concrete mixes through an experimental campaign in which four replacement levels (i.e., 10% FA + 20% MIBA, 20% FA + 10% MIBA, 20% FA + 40% MIBA and 40% FA + 20% MIBA, apart from the reference concrete) were considered. Compressive and tensile strengths, Young’s modulus, ultra-sonic pulse velocity, shrinkage, water absorption by immersion, chloride diffusion coefficient and electrical resistivity were evaluated for all concrete mixes. The results showed a considerable decline in both mechanical and durability-related performances of self-compacting concrete with 60% of substitution by MIBA mainly due to the aluminium corrosion chemical reaction. However, workability properties were not significantly affected, exhibiting values similar to those of the control mix.

Sludge disposal is becoming an issue at the municipal solid waste incinerator (MSWI), especially for environmental and economic reasons. This paper describes a case study of the optimization of the sludge management (SM) system at the MSWI in the Czech Republic. The original concept of SM at MSWI was designed as waste-free. However, the present operation indicates that there is a need to carry out regular extraction and disposal of sludge settling at the bottom ash tank and the bottom of the retention basin. The current status of SM causes problems not only in terms of operation but it also entails significant financial costs given the necessary regular cleaning of tanks. The aim of the applied research presented in this paper is SM optimization by a mobile sludge dewatering (DW) press unit with optimal polymer combination for DW.
