How does recycling work?
An important reason for glass recycling is that it saves a lot of energy. There is for the melting of waste glass for recycling less energy than producing new glass. The melting of waste glass will cost about 15% less energy. Course is for the collection, cleaning and sorting also requires energy, but this is much less than the energy needed to make new glass.
In addition, resources are saved by reusing old glass, there is finally less sand, lime and soda needs. Finally prevents the recycling of glass in the Netherlands annually 400,000 tonnes of waste, which is about 25 kilograms per capita.
Glass can be used repeatedly without loss of quality. When creating a new glass is 50-80% glass cullet are used.
To prepare waste glass for recycling, is a whole process in advance. Trucks pick up the glass from the glass containers and bring it to Maltha increasing. Maltha is a company that specializes in glass recycling.
First, all the broken glass shard to the correct size. Next, using strong magnets and other magnetic metal lids from glass objects stream. Parts that are lighter than glass, such as paper and plastic, are sucked away from the glass. Non-magnetic metals such as aluminum, the glass flow achieved through a combination of static tension and a brief acceleration of the glass flow, then the various sieved fractions. Finally, using laser and camera parts such as ceramic, stone and porcelain traced. When the location of these parts is detected, they are a blast of the band shot.
At the end of the ride should be 90 pounds of pollution per tonne of glass only 35 grams per tonne remain. However, before the glass to the glass factory is, it must still be stripped of organic residues (such as mayonnaise, peanut butter and apple sauce). This is done by a field deposit and that 6 to 10 weeks to compost. This approach to water saving.
