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.

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.

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.

Scrap recycling is one of the least popular in the United States even though most metals can be recycled and there are even some that have a high market value. The recycling of scrap metal is very important since by reusing metals we mitigate the exploitation of minerals, which are a limited resource, and their extraction generates a significant amount of greenhouse gasses.

Most of the waste can be left in the local recycling centers and received payment for it, in this way we avoid this waste ends up in landfills, where it would take hundreds of years to degrade.

Some of the metals that can be sold at recycling centers are copper (which is the best-valued metal on the market), aluminum, brass, lead, iron, and bronze. You can find these materials in all kinds of household waste such as; wires, pipes, kitchen sinks, food cans, soda cans, window frames, door locks, chandeliers and hinges, old jewelry, children’s toys, lamps, and tools.

Although almost most of the metals are recycled, some cannot be reused or that recycling centers do not receive, such as those used for paint or toxic products, some pipes, clothes hangers, and metal scraps, so it’s always best to check directly with your local recycling center.

Glass is infinitely recyclable, so it is critical to deposit it in the right place and prevent it from ending up in landfills, since glass never degrades and affects diversity and the environment if it is not treated correctly. Most of the glass found in landfills comes from discarded beverage bottles. In the United States, according to EPA data, the recycling rate for glass bottles is only 31.3%.

The best way to recycle glass bottles is to take them to local recycling centers, where you can even get paid for your bottle recycling. In most of these centers the price they pay per pound of glass is 0.1 USD/LB.

Also, recycling glass saves tons of natural resources, such as sand, soda ash, limestone, and feldspar. Recycling glass also reduces carbon dioxide emissions, as the glass from recycled bottles melts at a lower temperature than virgin materials, which means less energy consumption in the production of new bottles.
