vedio packaging

Packaging material include tinplate, aluminum, glass, plastic and cardboard, these material can recycled after use. There also have chance to reuse these packaging materials directly. Packaging should also be stored and handled carefully to avoid damage that may prevent its reuse.
These videos provide information about recycle process of these materials. For instance there is very high rate that 87% aluminum cans are recycled in Germany.
Around 83 per cent of waste paper recycled in Australia is used to make
packaging and industrial paper. The remainder is used to make printing and
Writing paper, tissues and newsprint.

Before recycle process separating and segregating packaging waste ensures it does not become contaminated. Successful recycling requires clear signage, training, monitoring and space as discussed in the Recycling solid waste fact sheet. If large volumes are collected consider a compactor to maximize storage space.
Tin Cans: Tin cans are made from 95% steel and only 5% tin. In order to be recycled the cans must be “detinned” using a caustic chemical solution that dissolves the tin from the steel. The steel is then sent to steel mills to be made into new products and the liquid is transferred into an electrolysis bath. When electricity is applied the tin collects on a plate where is can later be melted off and fashioned into ingots.

Aluminum: Beverage cans are the most-recycled consumer product in the United States. When aluminum reaches a recycling plant it is shredded and melted. The molten aluminum is gradually hardened into ingot form. These ingots can then be made into aluminum sheets or other desired forms. The metal sheets are used to make new aluminum cans and the cycle begins again. Making aluminum from recycled aluminum scrap take only 4% of the energy that it takes to make aluminum from raw bauxite ore.

Steel: Steel can easily be removed from other recyclables because it is magnetic. Once separated the steel is melted in a furnace and then poured into casters that roll the steel into sheets. Recycled steel cans may be made into new cars, girders for buildings, ships, or new food cans. Steel can also be recycled again and again. It does not lose any of its strength or quality in the recycling process. It can be a never-ending process that continues to save energy and resources.
cardboard :The process of recycling cardboard involves soaking the cardboard in water and stirring it until it has broken down into individual fibres. Each time cardboard is recycled the fibres get a bit longer but cardboard can still be recycled several times before the fibres break down completely. The cardboard is then cleaned and any contaminants like ink, bits of sticky tape and metal clips are removed. After cleaning, the pulp is then ready for draining and drying and rolling into sheets which removes any final traces of moisture and binds the fibres together to make the cardboard. The recycled cardboard is now ready to make into new cardboard boxes and packaging.
