Yeah, It Really Worth !
Although some recyclable products have a very high commercial value in relation to new products, keep in mind to shell out a little more to buy a notebook or recyclable bottle will reflect directly into the environment. This result may not be immediate, but if we all think like this, in a few years we will have a much better world than we have today. We must also remember that this world is priceless and most importantly, IT IS NOT RECYCLED!
Does it really worth ?
There are many pleadings about recycling and its efficiency in economy. Recycling is actually favorable to our pockets ?
On the environmental issue there isn't discuss , there are numerous benefits from implementing recycling programs , mainly due to retrenchment of landfills . Recycling is the most effective method for eliminating household waste .
Economic analysis of recycling includes what economists call Values , which are the priceless costs and benefits to humans and all of nature . Examples include : decreased air pollution and greenhouse gases from incineration, reduced hazardous waste from landfills , reducing energy consumption and waste reduction , which leads to a reduction in activities harmful to the environment such as mining and timber and the reduction of carbon emissions .
Certain requirements must be met for recycling to be economically feasible and environmentally effective.
• An adequate source of recyclates , a system to extract those recyclates from the waste stream .
• A factory capable of performing the reprocessing of recycled materials .
• A potential demand for recycled products .
It's difficult to determine the exact amount of energy consumed or produced in waste disposal processes. As the energy used in recycling depends largely on the type of material being recycled and the process used to make it. With aluminum, for example, much less energy is used when recycled than other processes. The EPA states that "recycling aluminum cans, for example, saves 95% of energy required to make the same amount of aluminum from its natural source, bauxite.
In many cases, the cost of recycling materials is also greater than the cost of raw materials, for example, the cost of virgin plastic resin is less than 40% recycled resin. These small differences can become a viable recyclable product with a product that will bring harm.
Recyclable books, for example, can cost up two times more than normal books. Just like the famous plastic grocery bags, which replaced the bags for free for a while, bringing a great turmoil to the people's pockets.
Not enough good will to change the world just recycling. We care about the planet in every possible ways.
What can be done?
To recycle a material there must be a procedure of prior selection, the separation of the general waste paper, plastic, glass, metal, organic and non-recyclable. A selection process is currently well known selective collection, which is nothing more than a garbage disposal made selectively.
After separation of waste, it is necessary to make a new separation into subtypes materials so that they have an interest. Then, all recyclable materials are selected in subtypes, usually by screening plants such as the City of São Paulo or cooperatives that after this procedure, compress materials to facilitate transport and sell to recycling industries.
To recycle, not enough to separate the materials from each other. We must keep in mind the three basic R of recycle. There are :

What is recycling?
Recycling means transforming objects used materials into new products to the consumer. This technique was created when the man saw that it was necessary to start reusing products to slightly decrease the side effects on the planet.
At the recycling process, beyond to preserve the environment, it also generates wealth in all the world. The most recycled materials are glass, aluminum (metal), paper and plastic. This recycling contributes to a significant reduction in pollution of soil, water and air and generate jobs. Many industries are recycling materials as a means to reduce production costs.
