“…Leaching test results conducted by Keulen et al [76] complied with standard reference: only salts release, mainly Cl and Br, increased at high replacement levels. Collivignarelli et al [58] confirmed the environmental compatibility of MSWI ash aggregates in concrete by means of leaching tests, achieving a lower release than sand for chlorine, chromium, and bromine. The pollutants mobility and concentration have been highly influenced by the pH [77].…”

“…However, MSWI ash concrete have shown a higher shrinkage, creep, and chloride-diffusion coefficients [69]. Collivignarelli et al [58] underlined the critical points for the environmental compatibility of aggregates based on MSWI ash: (i) the high amount of heavy metals, which affects durability; (ii) the high content of chloride, which enhances the steel corrosion. The problems concerning expansion and cracking are due to the development of gaseous hydrogen caused by the corrosion of metals in an alkaline environment [70].…”

The concrete industry is a core element of the building sector, but it has to deal with the increasing attention on the environmental issues related to the production process: increasing energy efficiency and the adoption of alternative fuels or raw materials represent the most relevant solutions. The present work analyses physical, mechanical, and environmental performances of concrete incorporating residues derived from four main sources (construction and demolition waste, residues from waste treatment, metallurgical industry by-products, and others), as substitutes of either fine or coarse aggregates. Fine aggregates showed the highest number of alternatives and replacement level, with the relevant impact on concrete properties; coarse aggregates, however, always reach a complete replacement, with the exclusion of glass that highly affects the mechanical performance. Construction and metallurgical industry categories are the main sources of alternative materials for both the components, with ceramic and lead slag reaching a full replacement for fine and coarse aggregates.

“…According to the Ministerial Decree 2006/186 [25], the unwashed BA from mass-burning kiln (MSWI-A) and the residues from fluidized bed reactor (MSWI-B), especially the exhausted SAND, were not suitable for recovery in simplified procedures [23]. This behaviour could be explained, as said above, as a consequence of several recirculation of the sand in the burning kiln during the combustion.…”

Abstract. The aim of this study was to assess the feasibility of concrete production using different kinds of industrial wastes as "recycled aggregate". The wastes studied in this work were: fly ashes and slags from Electric Arc Furnace (EAF) steel plant; foundry sands produced from foundry dies; slags from lead processing; Waelz slags; solid residues from municipal solid waste incineration (MSWI) plant (with mass-burning kiln and fluidized bed reactor); sludge from industrial wastewater treatment plants. Good compressive strength (similar to natural concrete) was achieved after 28 days of curing by concrete mixtures obtained with the partial replacement (from 7% to 40% by weight) of natural aggregates with slags from lead processing, foundry sands, Waelz slags and bottom ashes from MSW incineration. The worst mechanical and leaching behaviours were shown by concrete samples containing EAF fly ashes and sludge from industrial wastewater treatment. For the residues with the best performance, concrete products (kerbs and flat tiles) were casted. Their mechanical and leaching characterization has shown that the reuse of these residues for concrete product is feasible.

“…Following these data and goals to enhance application of the CE, the present review aims to analyse the state of the art in the potential application of agricultural industry residues both in building and environmental engineering fields. Unlike many other reviews and articles written about sustainable materials composed of renewable resources -both organic such as reeds (Asdrubali et al, 2015), banana bunch (Pappu et al, 2007), or inorganic such as incineration bottom ash (Collivignarelli et al, 2017a), and steel slag or foundry sand (Abbà et al, 2017) -this study focuses on natural materials at the end of their life cycle that can be reused in environmental engineering applications, mainly wastewater (WW) treatments, or as raw materials for insulation panels and boards. As the production of the waste materials is mainly located in the same farming countries, the present paper focuses on direct application of the residues suitable for the producing countries.…”

Valorization of agro-industry residues in the building and environmental sector: A review

Environmental pollution has become a relevant issue as the population rises and resources decrease. Reuse and recycling still have the greatest potential as they turn the waste into a new resource, representing the ‘closed-loop’ step of a circular economy (CE). Looking for new applications for agro-industry waste represents both an environmental issue, as its incorrect disposal is a cause of pollution, and a chance to exploit zero-cost natural wastes. The present review, with around 200 articles examined, focuses on possible reuses of these residues in (a) building construction, as additives to produce thermal and acoustic insulation panels, and (b) in water treatments, exploited for removal of pollutants. The selected materials (coconut, coffee, corn, cotton and rice) have industry production wastes with suitable applications in both sectors and huge worldwide availability; their reuse may thus represent a new resource, with an impact based on the production rate and the possible replacement of current inorganic materials. Along with possible implementation of the selected materials in the building industry and environmental engineering, a brief description of the production and supply chain are provided.
