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.

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.

Most of the local recycling centers work on a standard schedule according to their location and have a page on the internet, where you can check, what days they do not operate, what hours they serve, their address, and everything you need to know about your local recycling center.

Electronic waste, also known as e-waste, is all parts of electronic devices or broken devices, such as household appliances, televisions, electric stoves, air conditioners, microwaves, radios, computers, mobile phones, batteries, hard drives, motherboards, circuits, monitors, etc., that we discard.

Most e-waste contains a series of highly polluting materials, including heavy metals such as mercury, lead, cadmium, lead, chromium, arsenic or antimony, which not only harm the environment, but are also highly dangerous for human health.

The best way to dispose of electronic waste is by recycling. Electronic waste contains precious metals including gold, silver, copper, platinum, and palladium, as well as significant amounts of iron, aluminum, and plastics, which can be recycled. Giving away electronic devices that are no longer needed is always the best option, but if it is a product that cannot be repaired, it is important to deposit it at a local recycling center that accepts electronic waste. Recycling centers reclaim many of the materials from which these products are made, including plastics, glass, metal, and aluminum that can be recovered and reused in new electronics.
