by closing the life-cycle loop of glass. Circularity of glass can be achieved via reuse of post-consumer glasses or by recycling to get a unique product that can be used for several other purposes. Circularity of glass can help minimize the use of raw materials (sand), generation of landfilled waste and pollution emissions. For every 10% increase in the amount of recycled glass, or cullet, that is used to make containers, emissions are reduced by 5% and the amount of energy needed goes down 3%. Finely grounded recycled glass can be substituted for a portion of cement in concrete as fly ash and slag which if substituted, will help reduce the emission of given off as a by-product during concrete production. This can reduce the carbon footprint of concrete by 20-40%. Also, recycled crushed glass (on its own or in blends with natural or recycled aggregates) can be used in a range of road work applications including subbase, embankments material and drainage media in roads. Glass as secondary raw material The recovery and beneficiation of glass products produced via reuse or reprocessing of glass found in municipal wastes are very important goals from the environmental and economic point of view. Some technologies allow not only to reduce the volume of landfill waste but also to generate products of economic value by reuse, recycling and recorporation in manufacturing processes. Some of the recycling products from glass are; glass ceramics, slag, fly ash & bottom ash are known as secondary raw materials. Mixed with glass cullet, bottom ash can be easily transformed into homogeneous and inert glasses, which can be transformed into glass fibres or sintered glass-ceramics after controlled thermal treatments. Alternatively, bottom ash can be used to produce tiles, in particular glazed tiles containing vitrified bottom ash in the ceramic body, and possibly bricks. This work will however focus on the use of glass as a secondary material in construction industry. Reusing glass packaging The tendency in Europe is the increasing use of glass packaging to substitute plastic packaging. As a response to the increase of glass waste, the recycling and recovery rates has grown in the last 10 years. To assure the circularity and recycling of glass packaging it's possible to follow these principles applied to glass bottles: Leave no bottle behind: Ensure consumers have a way to recycle every glass bottle at a cost lower than waste disposal.
