1 - paper recycling:
The economic process of the first degree; This is because according to the statistical and the Environmental Protection Agency, USA, the production of one ton of paper from waste paper 100% will provide (4100 kw / h) energy, and will also provide 28 cubic meters of water, in addition to a lack of in air pollution caused by 24 kilograms of air pollutants. In spite of this, it is in the United States to recycle paper and 20.9 tons per year compared to only 52.4 tons of paper are disposed of without recycling. The recycled paper it uses to print daily newspapers.
2 - plastic recycling:
Plastic is divided into many types can be summed up in two main types Hard Plastic and Thin Film Plastic, and are washed prior to recycling plastic material caustic soda added to hot water. After that is dry and cracking plastic re-used in the manufacture of clothespins, and hangers, plastic pipes, electricity, not recommended to use plastic waste in the production of products that interact with food. The plastic bags are re-crystallized in the crystal machines.
3 - Recycle metal scraps:
It consisted mainly of aluminum and steel; where it can be re-melted in foundries, iron and smelting aluminum, and is considered solid waste that can be recycled 100%, and an infinite number of times, and you need the process of recycling steel for less energy than the energy needed for extraction of alloys, the the cost of recycling aluminum, they represent only 20% of manufacturing cost, and you need a recycling aluminum to only 5% of the energy needed.
4 - recycling glass:
The glass industry of sand is one of the industries that use energy significantly; the manufacturing process where you need to temperatures up to 1600 degrees Celsius, and the recycling of glass would need to be much less energy.
And presents the world today in landfills and centers landfill nearly two thirds of the aluminum manufacturer globally, and three-quarters of what it produces iron and steel plants, paper mills, but most of the plastic product ends up in places the collection of waste to get rid of burial or cremation.
