Remnants of the environment or waste or waste is any excess materials and undesirable, and can mean the garbage or trash. In biology, the term excess waste materials or toxins (toxins) that come out of living organisms.
It is difficult to define what waste. So what is the waste of some people considered to be of value to others. The American people succeed the daily rate of 4.5 pounds of waste per person, 55 percent of them household garbage.
And waste management means the combination, treatment and disposal of waste control. The aim is to reduce the negative impact of waste on the environment and society.
The development of industry and progress forward led to more by-products, whether in the form of gas or solid waste or liquids or semi-solid cast into the water or air or on the ground.
Is known as the raw material turned into a complete industrial products or half full when it does not find a secondary outputs this amount of benefit on the economic level they received them on the ground, water or air.
Of the most important waste that human pollution or environment is a private industrial waste if were not dealt with before dumped outside factories When the dumping of waste next to the factory motionless the wind to carry emerging from gases and possibly parts of them to distant places, and these gases What is Sam and can affect health humanitarian
Recycling is the process of recycling and use of waste, either homemade or industrial or agricultural, and to reduce
the impact of waste on the environment and accumulation, this process is done through classifying and separating waste on the basis of the raw material and manufacture each article individually.
The idea of recycling during World War I and II, where States were experiencing acute shortage of some basic materials such as rubber, which paid to assemble those materials from waste for reuse.
After years of recycling process has become the most important waste disposal management techniques to the many environmental benefits of this process.
For many years it was recycling direct producers of waste materials (scrap) is the primary form of recycling, but with the beginning of the 1990s began to focus on indirect recycling of any waste material to produce other products rely on the same raw material such as: recycling glass, paper, plastic, aluminum and other materials that are being recycled.
Manufacturers have found that if you take seriously the recycling programs can help reduce the cost of raw material and operating costs, and improve their image as accused permanent pollution of the environment.
Despite the belief of some that recycling is the top civilian, after ten years of applying the idea started a lot of people in the States applied to rotate in questioning the effectiveness of the process, is the best means of waste disposal? It was discovered in time, the cost of recycling is high compared to its advantages and return them.
The recycled product is usually less in quality of the product the user base for the first time, as it is not used in the same basic product purposes, notwithstanding that the cost of recycled product manufacturing cost higher basic raw materials which makes recycling economically irrational but a waste of energy.
So the question became confused! If the rotation method is not effective for disposal what is the best way to get rid of them? Of course, the only answer is in the hands of the scientists must find another way to get rid of waste and at the same time not wasted on non-renewable raw materials in them.
Already some ideas such as using crushed in waste glass as a substitute for sand in the paving of streets, or try to use the waste to generate clean energy, and we await the future emergence of many other ideas to get rid of the piles of waste in a way that preserves the environment and wasting energy.
Since then shouts environmentalists and green parties in much of the country, and when many environmental awareness and a genuine desire to stop the drain of resources. The call of Earth Day in 1970. And generation knows new vocabulary such as: environmental system (Ecological System) and greenhouse, and greenhouse effect (Effect Green House) and the ozone hole, and waste Recycling, and many attached to this latter expression in penance on the right of the poor planet.
In this topic, we will try to highlight the different types of waste recycling technologies (glass-paper-****l-plastic-etc. Etc) where we will present information in a simple and smooth easy-to-understand all God
1: cycled plastics waste
Plastic is divided into many types can be reduced in two main types dry Hard Plastic and plastic bags plastic Thin Plastic Film.
-Recycling plastic is by washing with caustic soda with hot water.
-After this is dry and cracking the plastic used to make pegs, hangers and plastic power hoses.
Not recommended for use in production of plastic waste products react with food, and plastic bags, are developed crystallization machines.
Plastic recycling industry touted as a solid investment because it increases demand, day after day, as it is in most industries, and fits all economic levels; anyone can invest in either small or large size of money. .. That plastic recycling, which was founded by thousands of small and medium-sized enterprises in the Arabic States.
Plastic recycling depends on household and commercial waste reaches the plastic waste to nearly 10%, but they differ in their characteristics and economic value and commercial as the exiting community, as well as plastic and access it again.
The plastic recycling process presents many investment opportunities for private individuals with small and medium-sized savings.
Recycling steps:
-Sorting waste: is the most important stage in plastic recycling, which requires access to good quality plastic good sorting of domestic and commercial waste, because the plastic loses its properties when deficiencies of other plastic types, the sort requires labor, creating many job opportunities.
Plastic waste is collected and sorted in several ways, including: the assembled houses, shops and hotels, and sell them to the nearest place of junk or scrap buyers itinerant street, or collected by the gravedigger in landfills.
-Panning: plastic material is washing soda or liquid soap plus Center
The hot water, which requires recycling of plastic material must be free from
Fats and oils, and UFOs.
-Plastic cracking:
If the plastic is cracking of steel (Hard Plastic) cracking machine, with a plastic waste among the Rotary arms fixed to be crushed, and controls the size of the cracker-specific slots for wire size pieces (granules) produced.
-Single & multi-film: disposable wash grains of high economic value to be placed in a machine which converts single & multi-film plastic parts of granules (beads)
