“…According to some authors [11,12,17,20], its use as aggregate is limited by the possibility of occurrence of the alkali-silica reaction. Moreover, there is the possibility of the formation of a weak transition zone, in the case of coarse aggregates, and low workability of the resulting compounds [13][14][15].…”

“…The most common wastes used in blended cements are blastfurnace slag, fly ash, silica fume, rice husk ash, and sugarcane bagasse ash [6][7][8][9][10]. Published results report that the use of glass particles for the partial replacement of aggregates or cement can result in beneficial or deleterious effects on the performance of cementitious compounds materials [11][12][13][14][15][16][17].…”

Different studies investigate the use of waste glass in Portland cement compounds, either as aggregates or as supplementary cementitious materials. Nevertheless, it seems that there is no consensus about the influence of particle color and size on the behavior of the compounds. This study addresses the influence of cement replacement by 10 and 20% of the colorless and amber soda-lime glass particles sized around 9.5 m on the performance of Portland cement mortars. Results revealed that the partial replacement of cement could contribute to the production of durable mortars in relation to the inhibition of the alkali-aggregate reaction. This effect was more marked with 20% replacement using amber glass. Samples containing glass microparticles were more resistant to corrosion, in particular those made of colorless glass. The use of colorless and amber glass microparticles promoted a reduction in wear resistance.

“…Recent research has shown that glass powder, obtained from grinding bottles soda-lime glass, develops pozzolanic properties and can be used as SCM [15] [16] [17] [18] [19]. The pozzolanic activity increases with the fineness of GP [15] [16] [20] [21].…”

As defined by the American Concrete Institute (ACI), alternative supplementary cementitious materials (ASCMs) and local materials are very important in concrete sustainability. As an ASCM, glass powder (GP) shows excellent pozzolanic properties. This paper focuses on characterization and the effect of GP on concrete properties compared to those of Class F fly ash (FFA) and ground granulated blast furnace slag (GGBS). Concrete incorporating 0, 20 and 30% of GP and other concrete mixes containing 30% of FFA or GGBS were cast. The concrete mixes considered in this study have water to binder (w/b) mass ratio ranging from 0.35 to 0.65. The mechanical properties such as compressive strength and durability including chloride ions permeability and chloride ions diffusion are evaluated. The results show that GP develops effects on mechanical properties similar to those of FFA and performs better than GGBS and FFA in terms of permeability reduction. GP reduces dramatically chloride permeability of concrete regardless w/b ratio, favoring an improvement of the concrete durability. Because of the interesting permeability developed by concretes incorporating GP, its use as an ASCM is promising.

“…Although significant effort has been made by the upstream European container glass industry, especially through cullet recycling whose rate has increased from 43% in 1990 to 71% in 2013 [31], further improvements are required to reduce its global environmental footprint, enhancing not only cullet use but also improving its quality. Indeed, broken and mixed glasses of different colours are economically and technologically difficult to reuse for the fabrication of new glass products, because these materials can cause a variation in the chemical composition of recycled glass, thus affecting the properties of new glass produced [32][33][34].…”

Long-Term Sustainability from the Perspective of Cullet Recycling in the Container Glass Industry: Evidence from Italy

Abstract:Glass manufacturing is a high-volume process, during which large substance quantities are transformed into commercial products, and significant amounts of non-renewable resources and energy (i.e., thermal fuels and electrical power) are consumed. The main purpose of this study is to give a critical explanation of the performance of the Italian container glass industry from the perspective of cullet being recycled, to outline the opportunities for transition towards circular business models that stimulate innovation in new sectors based on reverse-cycle activities for recycling. In 2015, disparate performances have been achieved as regards the container glass recycling rate in northern, central, and southern Italy, accounting for around 73%, 64%, and 55%, respectively. In fact, only northern Italy is in line with European targets, as by 2025 it will only need to increase its current performance by two percentage points, unlike central and southern Italy that will have to increase performance by, respectively, 11% and 20%. This shows a need to improve the efficiency of municipal waste collection systems in central and southern Italy, where undifferentiated waste still holds appreciable amounts of glass. Consequently, we propose several improvement channels, from the revision of waste legislation to the re-engineering of waste management supply chains.
