Video Reviews – Dale Wakeham – due 23rd Jul 12

How it’s made:

Cardboard box:
• The partially recycled card starts on a big roller which first is put through a corrugators to make the centre flute of cardboard, glue is then applied and then flat card is glued on either side. It is then cut to size and stacked; a trimmer is then used to cut the flaps and scores the folded sides of the box. It then goes through a folding machine to fold the box, and glue is applied and the sides stuck. The printing press applies the colours to the box.

Packaging tubes:
• Aluminium slugs are spun to orientate them correctly is each slug is then pressed to give it its exterior and interior shape. The tubes are then aligned and threads are added to the tubes, and then trimmed smooth. They are then heated to soften then. Epoxy resin is then applied to the interior to protect the contents. Rollers the paint the tubes, then dries then. They are then printed with there decals. Plastic cans are then screwed on. Latex is then added to the ends to add as lubricant, they then are shipped to be filled.

• Has a paper, foil and plastic layer. The paper is then printed on using a roller. Is is then put in a laminating machine that joins the foil and plastic layers. The large roll produced is then cut up into smaller rolls. The film is then sterilised and formed into a tube, then fills it with product, and cuts the tube into individually sealed packages. 

• Not available online anymore

Aluminium cans:
• Starts on a large roll, then pressed bent into circular cups, it is then pressed into the actual shape. They are then washed, dried and varnished. The rotation printed then applies up 5 colours, they are then varnished and then dried. A resin is added to the interior to stop the aluminium affecting the contents. A neck is then formed on the can and then a lip is added. They are then sent off to be filled and have the pull rings added.

Glass bottles:
• Silica sand, soda ash, recycled glass fragments and limestone are the main ingredients in glass. These materials is fed into a ferniest which then combines them then disposes the right about for one glass in dollops. It is then pit into a mold which makes it into a miniature version of the actually bottle. It then moves to a blow moulder that makes it the final size. Colorants can be added. They are then slowly cooled to prevent cracking. They are then lubricated, and inspected. 

Plastic Bottles & Jars:
• Made from PET. It is then melted and injected into a mould, making pre-forms. The pre-forms are heated to make them malleable, then lengthened with a rod and then blown to make it its actual size and shape.

How do they do it? – Recycling:
• Collected by trucks from houses, which is the taken to a depot which sorts all the rubbish, into plastics, glass, and paper etc. air is used to lift u and sort the lighter paper, while heavier metal and glass falls down. Metal is then removed using magnets separates it from the plastics. Now all the sorted materials are pressed into bails. The remaining non-usable garbage is then sent to a depot that fills trucks which then take it to a landfill. The landfill is lined with clay and non-breathable plastic. It is then compacted, and coved in soil

Giving packaging a new life:

Recycling paper:
• Paper bails are then sorted into different qualities, and then dissolved and pulped. Then any impurities and inks are removed. Other raw materials are added to produce the right type of paper. The fibres that are dissolved are put into a machine that lays, presses and dries the paper.

Recycling tetrapak:
• The shredded packs are pulped with makes the packs swell and the layers separate. The paper is removed and recycled. Concrete producers then use the plastic and aluminium. 

Recycling tinplate:
• Aluminium bails are then processed at steel works by smouldering.

Recycling aluminium:
• The aluminium bails are melted, cast and rolled, for use in production new aluminium products.

Recycling glass:
• The different coloured glass are sorted and made into fragments. The prepared fragments and then sent back to glass producers for melting and making new glass.

Recycling plastics:
• Plastics are sorted into the there categories. Polystyrene is ground and shaped into new polystyrene. Mixed or film plastics are made into new films in extruders. Plastic bottles are granulated and used in new products. PET can be reused to make into new bottles endlessly.

Sorting innovations:
• Fully automated sorting machine, utilising the traditional methods, then wet drum removes paper, the rest is then granulated, magnets retrieve the metal, then the different plastics are sorted using a number or centrifuges.
