The goal of this research was to remove arsenic from groundwater supplies via adsorption into media obtained from waste material generated as by-products from glass recycling programs and the seafood industry such as crushed glass and scallop shells. During the course of this research four new adsorbents were developed: ferric hydroxide coated crushed glass (FHCCG); ferric oxide coated crushed glass (FOCCG); ferric hydroxide coated scallop shells (FHCSS); and ferric oxide coated scallop shells (FOCSS). The adsorbents were characterized through evaluation of their structure, surface area, chemical composition, iron content, and coating stability. Efficiency of the adsorbents to remove arsenic from water was examined through batch kinetic and isotherm adsorption experiments. The adsorption capacity of the adsorbents was also evaluated by performing column experiments using real ground waters and a synthetic water. Arsenic removal to a concentration less than 10 μg/L was achieved with the FHCSS and more than 9000 bed volumes of water were treated before the breakthrough point was reached. The research results revealed that scallop shells coated with ferric hydroxideperformed better than crushed glass coated with ferric hydroxide. Both FOCCG and FOCSS had poor arsenic removal compared with FHCSS and granular ferric hydroxide (GFH). Ferric hydroxide coated scallop shells performed similarly to GFH.

This paper described new effective glass bottle fracture process for glass recycling by underwater shockwave. The high-speed fracture behaviors of glass bottles by explosive energy were discussed. In the proposed technique, the washing process can be skipped because the bottle crushing process execute in water. As a result, the recycling cost can be decreased. In order to clarify the behaviors of glass bottle fracture, the bottle was painted by 5 colors. The crushing experiment was executed under four explosive conditions. The influence of various explosive conditions on the cullet sizes were calcified by using painted bottle.

Purpose:  This article presentes the results of an in-depth and contextualized study on the problems in the commercialization of glass containers sent to the selective collection system of the city of Londrina-PR, Brazil.Design: The methodological strategy was the triangulation of sources of evidence desiring to understand the situational characteristics, as well as the operational and environmental challenges faced by the local actors involved, especially the cooperatives. Quantitative and qualitative study case using primary and secondary data collection from multistakeholders.Findings: The data collected here allow us to conclude that vitreous materials have demonstrated difficult commercialization processes and are among those materials that are economically less interesting for cooperatives, intensifying the high social fragility of cooperates.Practical implications: The search for solutions to environmental and economic problems caused by the high generation of municipal solid waste in Brazil still have strong deficiencies in methodologies and technologies. Social implications:  How the reverse logistics of vitreous packaging is operationalized has increased public financing with this type of material, since the sales price obtained by waste pickers does not corroborate the economic support of cooperative enterprises.Originality/value: This study allows to advance in the explanation and description of the way of structuring the reverse chain of vitreous packaging, especially in medium-sized municipalities in the inland.Keywords: post-consumption; packaging; glass; recycling; selective collection

Degree Of Degradation

The amendment of the Waste Framework Directive of the European Commission has set a new target for the use of recyclates. It is one of the most significant findings of this strategy that recyclates are currently too infrequently integrated into new products. Glass recycling, however, is widely accepted by the society. The chemical and physical properties of glass enable an almost 100% rate of recycling. Furthermore, the society is experienced in separating glass by colour, resulting in high-quality recycling glass for the production of new glass. Cullets are significant here. Evidently, the price of recyclates is linked to the price of primary material. Practical experience has shown, however, that pricing also correlates with different quality parameters such as degree of mixing, degree of degradation and presence of impurities. This paper examines the correlation between different quality features and how they affect the price of cullets. Experts from the Austrian processing and recycling business were interviewed about the important parameters of their quality inspection and how they affect the pricing policy. Additionally, quality parameters for input and output material are included. Besides the interviews, specific questions on correlations between the price and quality of cullets were e-mailed to several stakeholders in the glass industry. Experts from the glass processing industry did not confirm a correlation between price and quality, however: higher quality does not necessarily mean higher prices. Glassworks are ready to pay higher prices for higher qualities in order to meet their sustainability objectives or to expand their production capacities.

And Control

This chapter is partly based upon the results of the ARCHGLASS project, which analysed samples dating from the middle of the first millennium BC to the ninth century AD. With the introduction of Greco-Roman translucent glass, colour separation and control over the properties of a re-molten batch become much easier. Once the benefits of glass recycling in terms of raw material procurement, energy expenditure, and waste management are clear, the collection and reuse of cullet becomes common in the Roman world. It is estimated here that upwards from a quarter of the glass circulating in the Roman to early Byzantine economy at any time constitutes recycled glass. It is hypothesized that, apart from the possible addition of cullet to tank furnaces, glass recycling would have been a small-scale process, at the level of the individual workshop.

Glass Recycling

In this article, we analyzed the effects of an educational glass recycling program on primary schools and their students in Castilla-La Mancha (Spain). A sample of 89 schools, with 20,710 elementary students, was selected by simple random sampling. For the statistical analysis, descriptive techniques (frequencies and statistics), parametric (One Way ANOVA test), and non-parametric (Chi-Square test) inferential techniques were used, with a 5% significance level (p < 0.05). The program’s results showed that 153,576.3 kg of glass (with a value of 17,064.03 €) were recycled. Significant determinants of glass recycling were: School category (p = 0.043), previous environmental/recycling education (p = 0.046), geographic location of school (p = 0.030), gender (p = 0.007), and academic year (p < 0.05). With the program, students learned the importance of glass recycling, obtained a greater knowledge of and habits related to the same, acquired favorable attitudes towards the environment, and promoted glass recycling in their social circles. We conclude that environmental education about glass recycling has positive effects on glass recycling attitudes and behaviors in elementary school students and may be used as a measure to combat the problem of environmental pollution.
