Recycling is the process by which the raw materials that make up the waste that we use daily such as paper, glass, aluminum, plastic, etc., are transformed into new materials. This prevents these wastes from entering the seas or earth. But, for this to happen, a series of steps need to be carried out:

• At home – separate and clean waste.
• At local recycling centers – sort, pack, and store, for later sale.
• At processing industries – treat the materials and transform them into new products.

For a few years, the United States entered a crisis due to the accumulation of waste, which was triggered by the new waste policies of China, which was the main buyer of waste in the United States. These new policies are much stricter and among other restrictions, they lowered the minimum standards for pollutants to -1%, which excludes the majority of waste from the United States.

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.

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

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.

Not all the containers we consume are recyclable, even those that may seem so, that is why sometimes the local recycling center does not accept all the waste we carry. For example, while plastic bottles are the most widely recycled plastic products, not all bottles are made from the same plastic and their acceptance varies depending on the capabilities of each local recycling center.

In addition, the recycling services can reject your waste for recycling because it is dirty or contaminated since this means that it can no longer be recycled. Another reason facilities may reject materials is because of their shape, since some objects can damage the machinery, such as hooks. Other items that you cannot deposit in the recycling centers are:

• Syringes
• Bowling balls
• Aerosol cans that are not empty
• Plastic bags
• Batteries
• Diapers
• Electronics
• Ceramics
