In the United States, there are 633 material recycling centers. In these local recycling centers, the waste we generate is stored, and that has the capacity to be recycled so that other people or companies can take advantage of it. Waste that is not recycled takes many years to decompose, which pollutes and harms the health of humans and the earth.

In this sense, recycling centers are very important in the fight against environmental pollution, since they can clean, classify and pack a total of 100,000 tons of waste per day. However, the recycling centers cannot do all the work, the waste must have a correct treatment from the consumer, who must separate and clean the waste so that it can be classified correctly in the center and later sent to factories for transformation or processors.

To make sure we’re diverting as much waste from landfills as possible, it’s important to be aware of all the products that can be sent to your local recycling centers. There are many products that, if you separate them correctly, you can send directly to your local curbside recycling program.

Even so, as this varies depending on the capacities and facilities of the collection centers, it is always better to ask directly at your local collection center.

The products that can generally be deposited in recycling centers are:

• Paper, newspapers, magazines, and mixed papers (As long as they are clean)
• Bottles of plastic (almost all types)
• Glass jars and bottles
• Rigid plastic objects
• Cans, aluminum, steel, and metal containers

Paper is one of the easiest materials to recycle, however, for this to happen, it must be treated correctly from the beginning of the recycling chain, that is, from the consumer. The most important thing when it comes to recycling paper is that it does not contain polluting agents, since any type of food, oil, or some other residue makes it unrecyclable and can contaminate the entire batch.

Paper that is not recycled ends up in landfills and although it degrades rapidly compared to other materials since it is not reused, it increases the exploitation of forests and trees in the manufacture of the new paper.

As for cardboard boxes or cardboard in general, which is made up of several layers of paper, it is best to give it a second use whenever possible. On the other hand, failing that, keep them clean and break them so that they can be properly treated in the local recycling centers.

Sanitary landfills are designated sites for the disposal of garbage or other types of solid waste. Large holes are built at these sites into which garbage is buried. Until a few years ago, landfills were a major source of pollution due to the contact of toxic waste with the environment, but today they are designed to prevent waste from reaching and contaminating groundwater.

Sanitary landfills are built with a layering system that isolates debris from air and water, which is vital to preventing pollution. The garbage is compacted in cells to make the most of the available space, for which heavy machinery such as excavators and compaction equipment is used. Some of the polluting byproducts of garbage generation, such as methane, are captured and used to generate electricity. However, landfills continue to represent an important source of pollution, since when they reach their maximum capacity, the land on which they are built will take thousand of years to recover.

Waste transfer stations or material recycling facilities are sites where recyclable materials and waste are collected. At the stations, the waste is classified and separated to later be transferred to another area or facility for recycling, demolition, or landfill. The waste transfer stations are not just another stop for our garbage, here a fundamental process is carried out to reduce pollution by waste.

Waste transfer stations reduce waste going to landfills, preventing much hazardous chemical pollution remains from ending up in landfills, plus the transfer of waste from local collection trucks to larger vehicles, such as a train or ship, reduces significantly the cost of transportation and the environmental impact of transporting garbage.
