How do they do it?

Cardboard boxes:
Cardboard boxes were accidentally created in 1870. There are three main parts to corrugated cardboard: The flute and two liners. They are held together by glue made from waste starch. You can add more flutes and liners to create a more cushioned and stronger box.

Packaging tubes:
Made out of aluminium because they are lightweight, affordable and malleable. Aluminium slugs (coin size) are coated with lubricated powder. The slugs are then channelled into a forming press where impact intrusion shapes the slug into a tube. The tubes are then aligned and threaded using rollers. The tubes are then lacquered to protects the contents that will be put inside. The tubes are then painted using enamel paint and printed using polyester ink. They are then sent to their respective clients to be filled with contents.

Tetropak:
Keeps food and beverages safe without refrigeration for up to a year. Uses all recyclable materials. Made up of three layers which are laminated together. 1. plastic 2. paperboard 3. foil. Tetropak is leak proof. Printing occurs on the paper using a maximum of 6 colours. It is then cut and sent to manufacturer to be filled and finalise the shape.

Recycling:
Garbage trucks pick up garbage bins using a strong robotic arm. The trucks then go to a transfer centre. Recycling products are sorted and separated. papers metals plastics and glass are sorted. Contains almost a mile of conveyabelts. Sorts tones and tones adady. High powered air is blown to separate lighted materials leaving glass on the conveyabelt. Garbage is then bounced across rubber wheels. this splits up the lighter paper materials and heavier plastics and metals. The metals are then pulled out by a magnetic field. The machine then is fined its sorting. It is now in human hands. Humans sort out different types of plastics etc. The sorted waste is then compressed into bales for transportation to other recycling plants.
The pitt: Excess rubbish that can't be recycled. Where does it go? Trucks transport the garbage to landfill. compressors and bulldozers compress and move the garbage to level it out and to stop potential explosions from mixtures of land fill.

Aluminium cans:
Fully recyclable. Wate cuttings are recycled back into production line. The cans go through six stages of cleaning before they are printed on. Varnish is then applied to protect the ink.

Glass Bottles:
Glass uses less energy then plastic and metal to recycle. glass is made from natural ingredients. Celica sand, soda ash and lime stone. These ingredients are put together with recycled glass. They are then put into a furnace. the heat then melts everything together. the glass is then cut using a machine. the glass is then moved to bottle or jar forming machine. It is then moulded and blown. And blown again against another mould.

Plastic bottles and jars:
The most common plastic for bottles and jars is PET. Molds are used to create the shape is most commenly used. The stretching and re heat machine create the correct shape of the bottle. The machine makes over 10000 bottles per hour. Plastic scraps from the manufacturers are used for hygienic reasons.
