We also discovered that waste that’s collected from householders is taken to places called ”bring banks”, for sorting and bailing into loads. One problem here is taking out everything that shouldn’t have been placed in the recycling containers: people put all sorts of things into bottle banks, like plastic bags and even broken umbrellas. All this has to be removed by hand. Another difficulty is that toughtened glass used for cooking doesn’t fully melt at the temperature required for other glass, and so that also has to be picked out by hand.

Glass is easy to recycle because it can be reused over and over again without becoming weaker. Two million tons of glass is thrown away each year, that is,seven billon bottles and jars; but only 500,000 tons of that is collected and recycled.

Oddly enough, half the glass that’s collected is green, and a lot of that is imported, so more green glass is recycled than the UK needs. As a result, new uses are being developed for recycled glass, particularly green glass, for example in fiberglass manufacture and water filtration. A company called CLF Aggregates makes a product for roads, and 30% of the material is crushed glass. For recycling paper, Britain comes second in Europe with 40%, behind Germany’s amazing 70%.

When recycling started, there were quality problems, so it was difficult to use recycled paper in office printers. But these problems have now been solved, and Martin’s based in South London, produces a range of office stationary which is 100% recycled, costs the same as normal paper and is of equally high quality.
