Old televisions are a ubiquitous presence in homes, as well as in numerous businesses and companies worldwide. These electronic devices, which serve as the main source of information and entertainment, have a different purpose. The question then arises of what can be recycled from a television.

In this article we are going to show you what can be recycled from a television.

Authorized plants are required by law to recycle all electronic devices due to the presence of elements dangerous to the environment and health such as phosphorus, mercury and cadmium. In this situation, specialized companies emerge that capitalize on the recycling of old televisions, obtaining economic advantages through the acquisition of fresh and reusable raw materials.

About half of global e-waste consists of personal devices, including computers, screens, smartphones, tablets and televisions. In addition to the heating and air conditioning units, the rest is made up of larger appliances.

The statistics on the annual production of new devices are quite alarming. Furthermore, the electronics sector shows no signs of slowing down its expansion. According to the United Nations Office for Industrial Development (UNIDO), the electronics industry is responsible for producing more than 40 million tons of electronic waste per year, commonly known as WEEE (Waste Electrical and Electronic Equipment).

The rate of increase is expected to be between 16% and 28% over a period of five years, which is almost three times greater than the amount of waste produced by individual households. The United States and China are responsible for generating the largest amount of e-waste globally, collectively contributing to 32% of the total e-waste generated.

Every year in Spain the market is flooded with more than half a million tons of electrical and electronic devices, including a large number of televisions. In Spain It is estimated that it is necessary to effectively manage a minimum of 225.000 tons of waste per year. Unfortunately, this is not reality. Adequate recovery and recycling of all waste is not being achieved.

Instead of being recycled properly, many televisions end up in landfills. The recycling industry is increasingly looking for solutions to manage this new waste and avoid the depletion of natural resources, ultimately mitigating the environmental impact and pollution.

It is essential to understand the electronics recycling process and possess the necessary equipment to properly recycle them. What components of a television can be recycled? Most components found in televisions are recyclable and cover a wide range of parts:

  • La glass screen and internal circuit boards.
  • The Outer casings are composed of various plastics, while the interior contains different types of metal waste, including copper, brass and aluminum. Additionally, there are small amounts of precious metals such as gold, silver and platinum.
  • Cables and electrical parts various in disuse.

The typical process involves melting these metals into new components or products. Similarly, most of the glass found in partitions can be recycled and reused for a variety of new applications.

Similarly, printed circuit boards, known as PCB, they can also undergo recycling processes to recover valuable metals such as gold, silver and platinum. However, the main drawback of this recycling method is its considerable cost and the need for substantial energy consumption.

Recycling process

While the television recycling process is not overly complicated, requires the use of appropriate recycling facilities, advanced technologies and machinery to guarantee the implementation of the necessary security protocols.

It is important to keep in mind that not all televisions are the same. The process used to make a plasma television, for example, differs from that of an older cathode tube television. Typically, the main stages involved in each installation of Recycling encompasses the collection of discarded televisions at designated recycling points in various locations.

Upon arrival at designated recycling facilities, televisions undergo treatment and are sorted as part of the initial collection phase. Not all televisions are treated the same due to their different features. Digital televisions, including plasma televisions, and analog televisions, such as traditional cathode tube televisions, have different components, some of which may even contain toxic substances.

When dismantling a television, the initial step is usually to remove the screens. The specific techniques used for this task vary depending on the type of television being disassembled. To dismantle an analog television, the initial step involves removing both the Kinetoscope and the copper inside it. It is essential to exercise caution during this procedure due to the presence of dangerous gases and toxic elements.. In the end, the glass casing of the kinetoscope will break.

The recycling process for Smart TVs, also known as digital televisions, differs from the previous method. Instead of simply recycling the entire TV, the screens are now carefully separated from the panels that make up the TV. The LCD screen, LED boards or front panel are then removed and can be reused for use in other televisions.

The recycling process is especially complicated when it comes to electronic circuit boards, also known as PCBs. These intricate components require special attention due to their complexity. As part of the recycling procedure, These PCBs are carefully separated from other materials, including ferrous and non-ferrous substances. Once separated, they are crushed to facilitate further processing.

Following the circuits, wiring and connections are meticulously separated to extract valuable materials such as copper and brass, along with other essential components.

Crushing process

To properly recycle specific TV parts, including electronic boards and scrap metal and plastic from casings and wiring, a specialized crushing process using specialized equipment is necessary. Gold, silver and platinum are then extracted in small quantities using magnets and other procedures once the PCB is recycled.

No television can be completely recycled, as there is a fraction of hazardous substances or batteries that must be transported to specialized facilities for proper disposal, as they cannot be re-treated.

I hope that with this information you can learn more about what can be recycled from a television. televisions
