“…Previous studies using batch method have confirmed the gradual desorption of solute from adsorbent when the equilibrium concentration in solution decreased [18]. Successive leaching experiments prove that a lead complex sorbed on the surface of Fe colloid or FeOOH polymers could be leached out from the solid ashes [24]. This study further proved the negative effect of fluctuation in solute concentration in pore liquid.…”

“…Incorporation of BA has already been demonstrated by Nikravan et al for the partial substitution of aggregate and 2 of 16 filler in the case of concrete construction [4]. In addition, BA reuse as adsorbents has been investigated, due to its high porosity and large surface area [5].…”

A Circular Economy Virtuous Example—Use of a Stabilized Waste Material Instead of Calcite to Produce Sustainable Composites

et al. 2020

This work reports and analyzes the mechanical properties of some composites obtained using stabilized waste with epoxy resins E-227. For comparison, correspondent composite samples were realized using calcite as a filler. The recovered stabilized waste was obtained by means of a new method to stabilize municipal solid waste incineration (MSWI) fly ash (FA), based on the use of bottom ash (BA). The aim of this paper is to show that the stabilization process, which can be considered a zero—waste treatment, produces inert materials, that can be reused as a filler. The production of new filler was made on a pilot plant, designed to verify the transferability of the proposed stabilization technology. Mechanical analysis revealed that flexural modulus raises by increasing the filler content around 30% wt, independently of filler type, stabilized sample or calcium carbonate. Mechanical properties are lower in the samples with the high amount of filler due to the crowding effect. The morphology of composite materials showed a non-homogeneous dispersion of particles in stabilized sample filler, characterized by large particle agglomerates. Finally, according to the ESCAPE simplified method, the obtained composites result more sustainable in comparison with the corresponding ones produced by using natural resources (like calcite). These findings open new possibilities for the reuse of the stabilized material, in frame of circular economy principles, with environmental and economic advantages.

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). MOKSLAS -LIETUVOS ATEITIS SCIENCE -FUTURE OF LITHUANIADeginant atliekas gauti dugno pelenai ir šlakas yra daugiakomponentė sistema, kurią sudaro išsilydžiusių produktų ir nesudegusių dalelių mišinys, taip pat medžia-gos, kurios deginimo procese išliko beveik nepakitusios (geležis, spalvotieji ir sunkieji metalai, stiklas, keramikos nuolaužos ir mažos statybinių atliekų dalelės) .Dugno pelenų ir šlako savybės labiausiai priklauso nuo deginamų atliekų srauto sudėties.
