The production of human waste increases year by year. This vast amount of trash has formed islands hundreds of thousands of miles long in the oceans. There is so much litter that ends up in the oceans and on land that it has entered the food chain, greatly damaging biodiversity.

One way to reduce the amount of human waste is recycling in recycling centers; by lengthening the useful life of materials and preventing them from ending up in landfills, but also avoiding the production of new materials and thereby avoiding the over-exploitation of raw materials and the pollution that comes with the extraction of materials and their production.

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.

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.

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.
