The process of recycling glass?????

Question

I need it for a homework the process of recycling glass and i find pages with different ones each one so can anyone write the most common or just give me a pair of links to it???

thanx

Answer 1

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa...  I DO NOT KNOWN THE ANSWER!

Answer 2

Glass recycling presents an ideal for companies wishing to boost their "green" appeal in that glass can be recycled pretty much indefinitely at a much lower cost than producing new glass. The sad part tho, is that glass can also be re-used at 1/10 the cost of recycling it. Beer, wine and soft drink bottles can be used 10-20 times before being recycled into new bottles, but sheer laziness on the part of most American companies have lead to the use of plastic bottles and glass recycling.

If all packaging for drinks and food were made of reusable glass containers, America could reduce the energy requirements for packaging by up to 90%. So far companies are to lazy to do this, and the results include 1) tons of landfill due to use of nonrecycleable plastic containers, 2) added energy requirements of recycling glass rather than reusing it, 3) Loss of income to marginalized people who have traditionally picked out bottles to return for deposit money, 4) plastic contamination of foodstuffs such as milk. (Most people do not even remember what milk tasted like before we started putting it in plastic jugs.)

A school paper can give you the chance to explore issues a little deeper than just "How is Glass Recycled" , maybe you can write about "How is Glass Recycled and Why?"

Good luck to you!

Answer 3

All the glass that gets recycled here in Orkney is crushed and made into blocks for the Churchill Barriers.

Answer 4

Recylcling of glass is a simple and very useful process.

The basic principle governing the re-use of glass is that it never takes as much energy to remelt a glass as when it was first melted. The reason for this is somewhat complicated and likely outside the scope of this homework.

To recycle glass two things must be kept in mind. First, you want to only re-use glass of the same composition and second you'd usually only want to re-use glass of the same color. When recycling glass, the old glass (most often as bottles/containers) of like color and composition is collected and crushed. This glass is then added to the "batch" of a new glass, which consists of different powders depending on the desired final composition. Most commercial glasses (bottles, windows...) are soda-lime-silicates, which means the powders will be Silica (sand), Cacium (as CaCO3), and Sodium (as Na2SO4). To this mixture as much as 60% crushed recycled glass (called cullet) of the same composition and color is added to reduce the energy needed to melt and help with the glass melt mixing. In this way glass can be re-used an infinite number of times unlike plastics, which lose their mechanical stability after multpile re-uses.

Most glass-making companies will buy thier cullet from recycling companies, verify color and composition, and then add the cullet to thier batch. I should also note that cullet is in great demand right now but with the restrictions on composition and color placing a large burden on the recycling companies to manually sort the glass, much glass goes unrecycled to a landfill.

hope that helps, if you are not in the UK I suppose the process must be similar.

Pity about that other reply....how unhelpful!

Answer 6

The glass at our facility is not re-cycled.  It is ground up and used as road base or mixed with asphalt to go into road tops.

I hope this helps.
