Recycling Materials

Food/Drink Cans

'Tin' cans/Drinks cans are made of tinplate (tin-coated steel) but may also be made of aluminium or other metals.

Steel from cans and other sources is the most recycled packaging material. Around 65% of steel cans are recycled.

Firstly they are boiled to kill germs and strip off wrapping eg labels, they are then seperated, tin from alluminium by a magnet. Then they are melted and processed into a thin sheet of metal, only 5mm thick aprox (they monitar this with beta radiation) This sheet of metal is sold to industries and they turn it back into cans, companies then by these cans and put their product in it and it is then sold in your ssupermarket.

Tin/Steel are ferrous metals(magnetic)

Alumminium is a non-ferrous metal(non-magnetic)

Recycling Materials

Plastic Bottles

Polyethylene Terephthalate (PET, PETE or polyester) is commonly used for carbonated beverage and water bottles. 

Bottles made of PET are recycled to reuse the material out of which they are made and to reduce the amount of waste going to landfills.

In many countries, PET plastics are coded with the resin identification code number "1" inside the universal recycling symbol, usually located on the bottom of the container.

During recycling PET is sorted into color fractions; transparent/uncoloured, blue/green coloured and the remainder into a mixed colours fracction. The current problem is that more colours are being used on plastic bottles (e.g. amber for plastic beer bottles). This complicates the sorting process.

Plastics Cont.

The sorted PET is crushed, pressed into bales and sold to recycling companies. Transparent PET sells at the highest price as it is the most usuable.

 After buying the PET recyling companies crush it, wash it, seperate it and dry it. They further treat the PET by shredding it into small fragments. These fragments still contain resideus of the original bottle (i.e. paper labeling and bottle caps). These are removed using several processes after being removed you aquire pure PET fragments/flakes. They are used to reimplace polyester, they can be used to make; polyester fibres (later used to make clothing, pillows,carpets, etc.), sheets or back into PET bottles

Newspapers are made of paper. They take longer to recycle than a plain piece of paper.

First, the newspapers are dumped into a chemical detergent solution. They are slushed through while the detergent dissolves the ink so that it can be carried away

Next, the slushy pile of paper is sent through a filtering process to remove all foreign articles that might be attached to the newspapers, which includes things like staples, bits of tape, dirt, dead houseflies or crumbs

The pile of paper is still very dirtys and must next be bleached to draw out all the color and produce the plain white of new paper look. After or even during the bleaching process, the newspaper will get a bit of backbone added in the form of additional wood pulp

Newspapers Cont.

Next, its loaded onto rolling conveyor belts that are made of screens. As the newspapers roll down the line, the excess liquid drips out.

At the end of the conveyor line, the paper is fed into gigantic rollers. These rollers use heat and pressure to draw out any remaining moisture and flatten the recycled paper into new paper.

The new paper is trimmed to the correct size, rolled and sent to become another newspaper.
