“…The incineration of MSW will likely become a feasible and effective management strategy. After incineration, waste is reduced by 85-90 % in volume and 65-80 % in mass (Valle-Zermeño et al 2013). It is estimated that incineration generates about 3 million tons of MSWI ash each year in China (Yang et al 2012).…”

An experimental investigation was carried out to evaluate the mechanical properties of concrete mixtures in which coarse aggregate was partially (30, 50 or 70 %) replaced with pre-washed municipal solid waste incineration (MSWI) bottom ash. Results indicated that bottom ash reduced the compressive strength, elastic modulus, and levels of heavy metals in leachate when used as a replacement for gravel, and that the maximum amount of MSWI bottom ash in concrete should not exceed 50 %. To analyze the effect mechanism of bottom ash in concrete, the degree of hydration and the following pozzolanic reaction characterized by the pozzolanic activity index, and the porosity distribution in cement mortar. The study indicates that improved properties of concrete are not solely later strength gain and reduced levels of heavy metals in leachate but also the progression of pozzolanic reactions, where a dense structure contains a higher proportion of fine pores that are related to durability.

Procese susidaro du pagrindiniai atliekų srautai: pavojingi -lakieji pelenai (angl. fly ash) ir nepavojingidugno pelenai ir šlakas (angl. bottom ash). Dugno pelenais ir šlaku yra įvardijamos degimo kameroje degimo proceso pabaigoje iškrentančios deginimo proceso atliekos bei nedeganti liekana, susikaupusi degimo kameros dugne. Pelenus ir šlaką taip pat gali sudaryti per grotelių kiaurymes iškrentančios dalelės bei nepavojingosios garo katilo dulkės. Dugno pelenai sudaro 85 % proceso liekanų masės (vidutiniškai 16-35 % pradinės kuro masės) (Rambaldi et al. 2010;Yang et al. 2012;Schabbach et al. 2012;Wei et al. 2011).

“…Its chemical composition is similar to clay, with a good lime binding capacity. Thus, it is primarily used for production of cement [15], clay bricks [16], hollow blocks [17], aerated concrete [18], and other building materials [19][20][21]. It can be also be used as an agricultural fertilizer and soil conditioner due to its low bulk density, high water retention capacity, favorable pH, and other properties [6,22,23].…”

Air pollutants such as volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), as well as water pollutants including heavy metal, are harmful to human and environment. Effective control and reduction of their pollution is therefore an important topic for today's scientists. Fly ash (FA) is a type of industrial waste that can cause multiple environmental problems if discharged into the air. On the other hand, because of its high porosity, large specific surface area, and other unique characteristics, the FA can also be used as a low-cost and high efficient adsorbent with some simple modifications. This paper reviews the effects of FA on treatment of the above air and water pollution based on our research experience over many years, including to the current status of global FA utilization, physicochemical properties, principle of adsorption, and the application direction of FA in the future. It focuses on the use of nanocomposite technology to fabricate functional FA fibrous membranes to adsorb VOCs from air, and treat heavy metal wastewater. This present review first describes the fabrication technology of FA nanocomposites and their mechanism of adsorption VOCs from air. Utilization of nanofiber technology to fabricate multi-functional FA emerging composite materials to mitigate air and water pollution has great potential in the future, especially use of pollutant material to control other pollutants.
