VHS tapes are an important medium in film history, influencing art and cinema. The VHS cassette is a plastic shell held together with screws and containing a tape. The plastic shell is made of polystyrene, and the inner tape is made of a phthalate-laden form of the plastic polyethylene, often sold under the trade name Mylar. The Mylar is coated with toxic metals, which allow the tape to carry a magnetic signal. The tapes are classified as electronic waste due to the presence of these toxic metals, and they must be disposed of properly.

What You'll Learn
VHS outer shells are made of recyclable plastic
The outer shells of VHS tapes are made of plastic, and some sources suggest that this plastic is recyclable. The plastic shell of a VHS cassette is held together with five Phillips-head screws. The tape inside the plastic shell is made of a phthalate-laden form of the plastic polyethylene, often sold under the trade name Mylar, which is not recyclable.
Some VHS tapes have been known to consist of an incredibly lightweight body made largely of polystyrene foam, with only the rotating components like the tape reels being made of hard plastic. In the late 1990s, there was a disposable promotional variation of the VHS format called V-Lite, which was constructed largely with polystyrene. However, this polystyrene variation is not common, and most VHS tapes are made of plastic.
VHS tapes with plastic shells were more common in the UK than in the US. In the US, blank tapes almost always came in cardboard, while in the UK, tapes were usually housed in plastic cases. Plastic shells were also used for children's movies and rentals because they were harder for kids to destroy.
The plastic shell of a VHS tape can be reused or recycled by looking for local recycling companies or finding vintage shops or record stores that may accept VHS tapes.

Inner tape is non-recyclable plastic
The inner tape of a VHS cassette is made of a phthalate-laden form of the plastic polyethylene, often sold under the trade name Mylar, which is not recyclable. While the outer plastic shell of a VHS tape is theoretically recyclable, the inner tape is not. This is because the inner tape is coated with toxic metals, especially chromium, which allows the tape to carry a magnetic signal.
While the plastic shell of a VHS tape is typically made of polyethylene or polystyrene, the inner tape is made of a different type of plastic that is not recyclable. This non-recyclable plastic is often sold under the trade name Mylar, which is a phthalate-laden form of polyethylene. Mylar is used for the inner tape because it is thin and flexible, allowing the tape to move easily within the cassette during playback and recording.
The use of Mylar for the inner tape also provides a stable base for the magnetic coating that holds the video signal. The magnetic coating is made of magnetic oxide particles, which are bonded to the Mylar base using a polyester urethane binder material. This construction ensures the stability and longevity of the VHS tape, as the magnetic oxide particles are unlikely to degrade or cause signal losses over the lifetime of the tape.
While the inner tape of a VHS cassette is not recyclable, it is important to dispose of old tapes properly. The toxic metals present in the tape, such as chromium, can eventually leach out and potentially contaminate the surrounding water and soil if dumped in a landfill. Therefore, it is recommended to explore alternative disposal methods, such as electronic waste (e-waste) recycling programs, to ensure the safe and responsible disposal of VHS tapes.
Overall, while the inner tape of a VHS cassette is made of non-recyclable plastic, proper disposal methods are crucial to mitigate potential environmental hazards associated with the toxic metals present in the tape.

Plastic is coated with toxic metals
The plastic shell of VHS cassettes is made of polystyrene, hard plastic, or a combination of both. The inner tape is made of a phthalate-laden form of the plastic polyethylene, often sold under the trade name Mylar.
While plastic itself is already harmful to the environment, its impact is exacerbated when it is coated with toxic metals. Historically, many additives and catalysts used in plastics were based on compounds of toxic metals (and metalloids), such as arsenic, cadmium, chromium, and lead. These toxic metals can have detrimental effects on the environment and human health. For instance, in vitro studies have shown that the mobilization of cadmium and lead from historical microplastics can exceed safe concentrations, as specified by the European Toy Safety Directive.
The inner tape of VHS cassettes is one such example of plastic coated with toxic metals. The Mylar plastic of the tape is coated with toxic metals, especially chromium, which allows the tape to carry a magnetic signal. As long as the tapes remain intact, they are not dangerous. However, if they start to break down, the toxic metals can leach out, potentially contaminating the surrounding water and soil. Due to the presence of these toxic metals, VHS tapes are classified as electronic waste or "e-waste," and proper disposal methods must be followed to prevent environmental contamination.
Black plastics are another area of concern regarding plastic coated with toxic metals. Black-colored plastic, commonly used for kitchen utensils and toys, often contains unregulated amounts of toxic chemicals, including heavy metals, phthalates, and flame retardants. The electronic waste used to create black plastics can contain toxic chemicals like cadmium, lead, nickel, chromium, and mercury. When black plastics are exposed to heat, there is an increased likelihood of these toxic chemicals leaching into food and drinks, posing a significant hazard to human health.
The presence of toxic metals in plastics has serious environmental and health implications. The toxic metals can leach out over time, contaminating the surrounding environment and posing risks to human health, especially during the ingestion of contaminated water or food.

VHS tapes are considered e-waste
VHS tapes are made of #5 polypropylene plastic, which will take centuries to biodegrade or photodegrade. The plastic shell is held together with metal screws, and the inner tape is made of a phthalate-laden form of polyethylene, often sold under the trade name Mylar. This plastic tape is coated with toxic metals, especially chromium, which allows the tape to carry a magnetic signal.
Due to the presence of these toxic metals, VHS tapes are considered electronic waste or "e-waste". They cannot be disposed of in landfills because the metals will eventually leach out, potentially contaminating the surrounding water and soil. Therefore, it is important to recycle VHS tapes properly through specialised e-waste recyclers. Some local recycling companies, vintage shops, or record stores may accept VHS tapes, and organisations like the Internet Archive or the VHS Preservation Society accept rare or historically valuable tapes for cultural and educational preservation.
VHS tapes should not be placed in standard recycling bins or brought to landfills. The toxic metals in the tapes can contaminate the environment if they are not properly recycled. While the plastic casing will take a long time to degrade, the inner tape is coated with metals that are considered hazardous waste.
Recycling VHS tapes can be challenging due to the mix of materials they contain. The tapes must be shredded, and the materials separated by water or magnets. Some components can be reused, while others, like the Mylar tape, must be disposed of in a safe and environmentally responsible manner.
In addition to recycling, there are other options for disposing of VHS tapes responsibly. For example, converting family videos to DVDs or digital files ensures that precious memories are preserved. Donating tapes in good condition to thrift stores, creative reuse centres, schools, or community art programs is another way to give VHS tapes a second life.

Promotional VHS tapes were made of polystyrene
The VHS cassette is a plastic shell held together with five Phillips-head screws. The outer cases of VHS tapes are made of plastic and are theoretically recyclable. The inner tape is made of polyethylene, often sold under the trade name Mylar, which is not recyclable. The tape is coated with toxic metals, particularly chromium, which allows it to carry a magnetic signal.
In the late 1990s, a disposable promotional variation of the VHS format called V-Lite was introduced. These promotional VHS tapes were made of polystyrene, with only the rotating components, such as the tape reels, made of hard plastic. The polystyrene construction of these tapes allowed for a more lightweight and cost-effective alternative to the standard VHS format.
Promotional VHS tapes, with their polystyrene construction, lacked some of the standard features found in traditional VHS cassettes. They often had no windows and minimal internal mechanisms, such as the absence of a reel lock or proper rollers. The use of polystyrene in these tapes prioritized cost-effectiveness and disposability over durability and long-term functionality.
While the promotional VHS tapes were made primarily of polystyrene, some variations included a thin plastic shell over the polystyrene core to provide rigidity and compatibility with VCR mechanisms. This plastic shell was a single layer that served as a protective coating, ensuring the structural integrity of the tape.
The choice of polystyrene for promotional VHS tapes reflected a specific purpose and target audience. These tapes were often distributed by cable companies to showcase their services, such as promoting the offerings of cable TV to prospective customers. By utilizing polystyrene, these promotional tapes could be produced at a lower cost, making them ideal for mass distribution and marketing purposes.
