GLASS

Like aluminum, glass can be infinitely recycled by melting, without losing any of its properties; also, like aluminum, the recycling costs are lower than those of making glass from raw materials, thus saving energy. But from our point of view glass poses a big problem: it’s practically corrosion-proof, because it decomposes in about… one million years! Glass is, by far, the most resistant waste product ever generated by humanity (PET bottles, with a life span of at most 1,000 years, takes the second spot). To put it another way, your beer bottle in the fridge, if it’s not recycled, will probably survive in the same form for a long time after our species will have disappeared from the face of the Earth. It’s not very encouraging to think that all that will remain of our civilization will be some empty bottles.
 
How is it recycled?
 
The whole process is relatively long, but essentially simple: the bottles are washed, then sorted by colors (the pigments cannot be separated), broken, ground, after which impurities are eliminated (labels, paper, metals, etc.), and the ground product is then melted and worked into pellets – the raw matter for the various uses of recycled glass. Colored glass can only be used to make glass of the same color, which also makes clear glass the most valuable, because it can be reused for many more purposes. Caution should be given to heat resistant glass: this cannot be recycled with ordinary glass because it interferes with the melting process.
Usually, recycled glass is used in glass products for home, although it has some more “exotic” uses – such as the well-known fiberglass insulation for hot water pipes, or as an ingredient in some concrete mixtures or sanitary products like bathroom and kitchen sinks.
 
What are the advantages of recycling?
 
Glass is the most resistant pollutant and its recycling saves money and energy. Next to paper, glass accounts for the largest share (by weight) of municipal waste.
 
What can I recycle?
Any kind of glass bottle, colored or not, preferably washed with clean water.
 
Will I receive a bonus?
 
Yes, the SIGUREC machines will give you a shopping voucher for collected glass bottles!
