Multicriteria Analysis of Glass Waste Application

Abstract

Increasing amounts of glass waste present serious challenges in waste management to avoid environmental problems that might be created if it was to be deposited in landfills. Theoretically, glass waste is fully recyclable, but, if contaminated, containing impurities, broken or mixed colour, it makes the re-melting process impractical. A great practice of using secondary recycling material was reached by the construction industry involving glass waste in concrete mixtures as fine aggregatesreuse of waste glass in concrete production not only preserves natural resources, reduces greenhouse gas emissions, saves energy, furthermore, it may improve concrete sustainability and enhance the properties of concrete when used at the optimum quantity. In this study the container glass waste evaluation was performed, as well as experimental research of mechanical properties of four types of concrete mixtures containing glass waste as fine aggregate. The best alternative of replacement of sand by glass waste scenario in concrete production was determined, employing the multicriteria decision-making method TOPSIS.

Use of Multi-Criteria TOPSIS Analysis to Define a Decarbonization Path in Colombia

“…The Technique for Order Preference by Similarity to Ideal Solution (TOPSI S) methodology was the chosen one as multi-criteria analysis system for selecting the path to follow in the energy sector. This method concept relies on the chosen alternative that should have the shortest distance from the ideal solution and the farthest from the negative-ideal solution and it has been used before for selecting application methods within the environmental field [32], [33].…”

The Effect of Pozzolanic Waste of Different Nature on the Hydration Products, Structure and Properties of Hardened Cement Paste

“…Waste glass is composed of silica (SiO 2 ) and various metal oxides, namely Ca, Al and Fe. XRF analysis conducted by other authors shows that the main component of waste glass is silica, which accounts for more than half (68.9 ± 1 %) of the total mass [10][11][12][13][14].…”

Green Combined Resource Recycling System for the Recycling of Waste Glass

“…Although the stable nature of glass makes it difficult to dispose of, it also makes it easier to reuse. Theoretically, the glass material can be completely recycled without any mass loss . A number of research works on waste glass recycling have been carried out, and they can be roughly divided into open-loop recycling and closed-loop recycling.…”

“…Theoretically, the glass material can be completely recycled without any mass loss. 9 A number of research works on waste glass recycling have been carried out, and they can be roughly divided into open-loop recycling and closed-loop recycling. The open-loop recycling process is usually applied to waste glass of poor quality, which cannot be used as a raw material for glass products.…”
