Introduction
Recycling means transforming material objects used in new products for consumption. This need
was awakened by humans, from the moment they found the benefits that this procedure back to
the planet Earth.
From the 1980s, the production of packaging and disposable products has increased significantly,
as well as the waste production, especially in developed countries. Many governments and NGOs
are charging companies responsible postures: economic growth must be combined with
environmental preservation. Activities such as selective collection campaigns of garbage and
recycling aluminum and paper, are already common in many parts of the world. In the recycling
process, which in addition to preserving the environment also generates wealth, the more recycled
materials are glass, aluminum, paper and plastic. This recycling contributes to a significant
reduction in pollution of soil, water and air. Many industries are recycling materials as a way to
reduce production costs.
First we need to change our consumption habits, practicing conscious consumption, avoiding
waste, thinking of the packages then will go to the trash and giving preference to those that are
recyclable. Then we have to learn to separate recyclable materials from recyclable and not
encourage friends, neighbors and relatives to do the same.
It is important to know that the material collected by these cooperatives generate employment for
many families, help preserve the environment and reduce the costs of waste treatment.

Recycling
It is the process that aims to turn used materials into new products with a view to reuse. By this
process, materials to be used for the permanent waste can be reused.
Materials recyclables
Many materials such as, for example, aluminum can be recycled with reuse level of nearly 100%.
Melted, it returns to the production lines of packaging industries, reducing costs for businesses. As
well as in cities, in rural recycling also happens. The organic waste is used in organic fertilizer
manufacturing for use in agriculture.
See examples of Recyclable Products:
• Glass: food jars (olive, corn, cheese, etc.), bottles, jars drugs, glass shards.
• Paper: newspapers, magazines, brochures, cardboard boxes, paper packaging.
• Metal: aluminum cans, steel cans, nails, covers, paste tubes, copper, aluminum.
• Plastic: plastic containers, PET bottles, plastic bags, packaging and grocery bags.
Lifetime Product
In nature all dead plants and animals rot and decompose. They are destroyed by larval worms,
bacteria and fungi, and the chemicals they contain return to earth. They can stay in the soil, in the
seas or rivers and will be used again by plants and animals. It is a natural process of re-use of
materials. It is an endless cycle of death, decay, new life and growth. Nature is very efficient in
the treatment of waste. In fact, there is no proper garbage because it is used again and turns into
reusable substances.
While nature is efficient displays in reuse and recycling, the men are in production waste. Much
of this waste overloads the system. The problem is compounded because many of the substances

manufactured by man are not biodegradable, this is not decomposes easily. Glass, cans and
some plastics are not biodegradable.
Selective waste collection
Garbage collection is a process consisting of the separation and collection of waste discarded by
companies and people. Thus, materials which can be recycled are separated from organic waste
(scraps of meat, fruit, vegetables and other foods). This latter type of waste is disposed of in
landfills or used for manufacturing of organic fertilizers.
Recycling paper
It is a procedure to recover the cellulosic fibers from old paper and incorporate them in the
manufacture of new paper. It is not a process free of waste production, but the production of virgin

pulp also is not, and so always minimize the problems related to the production of raw
materials and the disposal of old paper.
It is important to note that the roles cannot be recycled indefinitely without losing quality. After
each use, they lose part of their property and can only be recycled for other use, and a little less
noble, than the original.
Glass recycling
Glass is an ideal material for recycling and may, depending on circumstances, be infinitely
recycled. The use of recycled glass in new containers and ceramic enables the conservation of
materials, reduced energy consumption (which helps nations have to follow the guidelines of the
Kyoto Protocol) and reduces the amount of waste that is sent to landfills.
The glass recycling essentially occurs in three stages. The first step is the collection, which is made
by collectors, because in Brazil the selective collection is still not a reality in most cities. At this
stage the glass is simply collected and taken to central recycling. However being a heavy and
sharps such transport is difficult.
The second step is the separation when the glass is separated by colors and types. At this stage it
is important to eliminate all kinds of special glass, such as Pyrex, since these, even in small
quantities, cause large changes in viscosity of the final product.
Finally the material is washed to remove the packaging, ground to facilitate liquefaction and
liquefied again becoming raw material for industries.
Tire recycling
Used tires can be reused after its retreading. This is the removal by scraping the worn tread housing
and placement of a new band. After vulcanization, the tire "retread" shall have the same durability
as the new. The economy of the process favors the most expensive tires, as the transport (truck,
bus, and plane) because these segments the costs are better monitored. There are limits on the

number of retreading a tire support without affecting its performance. Thus, sooner or later,
the tires are considered unusable and discarded. Discarded tires can be recycled or reused for
various purposes.
The tires are cut into chips and purified by a sieve system. The chips are ground and then subjected
to steam digestion of water and chemicals such as alkalis and mineral oils for vulcanizing them.
The product can then be refined in mills to obtain a uniform blanket for obtaining rubber pellets.
The regenerated rubber has two basic differences of the parent compound: has inferior physical
characteristics because no process can of vulcanizing the rubber completely, and has an undefined
composition, since it is a mixture of the components. However, this material has many uses: cover
play areas and sports courts, manufacture carpets for automobiles; pedestrian crossings; heels and
soles of shoes; glues and adhesives; air chambers; domestic squeegees; strips for upholstery
industries; bushings for truck and bus axles, etc.
Importance
The recycling of paper is of paramount importance for the environment. As we know, the paper
pulp is produced by certain types of trees. When we recycle paper or buy recycled paper we are
contributing to the environment because trees have to be cut. We cannot forget also that the paper
recycling generates income for thousands of Mozambican people who work mainly in recycling
cooperatives and recyclers of paper.

Conclusion
Throughout this paper we understand that recycling is the recovery and transformation of any
waste. Its economic importance is reflected in the possibility of acquiring materials for more
favorable prices than the same materials before their first use. The principle of recycling is used in
all applications involving conservation of Earth's natural resources and solving environmental
pollution problems.
The paper can be turned into pulp and reprocessed into recycled paper, cards and other products.
The glass may be ground and used to replace sand in construction, in concrete or asphalt, or can
be remelted and used in the manufacture of new glass materials. Certain plastics can be remelted
and manufacture them to synthetic boards. These boards not being biodegradable, can be used for
fencing, signs, construction sites, etc. The metals can be melted down and remanufactured.
Recycle aluminum can save about 90% of the energy used to make the same object with aluminum
from the blend (aluminum ore). Rests of food and household waste (grease, sheets, etc.) can be
processed to produce fertilizer by composting. Textile products may be recycled into fertilizer for
use in agriculture. Old tires may be fused or crushed and formed into numerous products.
The recycling becomes more cost effective to make the pre-separation of the products to be
recycled. With the growing environmental awareness of the population, this system is gaining
support in many communities, where they are distributed containers for plastic, metal, glass, paper,
etc. Abandoning all these materials implies a prior selection prior to their distribution to the
different industries.
Recycling is an essential means to the environmental. We think there should be more people to
contribute to recycling because recycling is for the good of us all.
