Plastic ring carriers are used to hold together multi-packs of beverage cans
To address environmental concerns, some manufacturers have adopted biodegradable or compostable materials for their plastic ring carriers. For example, Saltwater Brewery developed eco-friendly rings that are fully biodegradable and compostable. Other alternatives, such as paperboard baskets and LDPE plastic can carriers, have also gained popularity. Additionally, recycling initiatives like the RingRecycleMe program offer free mailing services for consumers to return plastic rings for reuse or recycling.
Despite these efforts, plastic ring carriers continue to face criticism due to their limited recyclability. In many places, including Massachusetts, plastic can carriers are not accepted through curbside recycling programs. This has prompted some states, like Vermont and Canada, to phase out single-use plastic rings in favour of more sustainable options. Cardboard can carriers are presented as a practical and eco-friendly alternative, addressing the environmental impact of plastic waste.
While the transition to biodegradable materials and cardboard carriers is ongoing, it is important to note that proper disposal of plastic ring carriers is crucial. Consumers are advised to cut each loop before disposal to prevent entanglement and minimise the risk of harming wildlife.

They are notorious for causing harm to wildlife, especially in the marine environment
Plastic ring carriers, also known as six-pack rings or six-pack yokes, are sets of connected plastic rings used to package multi-packs of beverages, particularly six-packs of canned drinks. They were invented in the 1960s and soon replaced paper and metal-based holders. However, it didn't take long for environmentalists to recognise their harmful effects, especially on marine life.
Large marine mammals, such as blue whales, are highly vulnerable to plastic entanglement, especially from ghost fishing gear made of plastic ropes, nets, and pots. An estimated 300,000 whales, dolphins, and porpoises die each year from ghost gear entanglement. Sea turtles are also at risk of entanglement from six-pack rings, which can get caught around their shells and necks.
Even when the plastic ring carriers break down into smaller pieces, they can still be ingested by marine animals. Microplastics can adsorb toxins, which then transfer to the fatty tissues of the organisms that ingest them. While photodegradable plastic ring carriers have been mandated in the US since 1994, they do not solve the problem of plastic ingestion by marine life. The decomposition process can result in plastic fragments and microplastics that are still harmful to marine animals.
To address these issues, some companies have developed eco-friendly alternatives. For example, Salt Water Brewery introduced compostable and edible ring carriers, while Carlsberg Breweries used a special glue to hold their six-packs together.

In the 1970s, some US states banned non-degradable ring carriers, and manufacturers now use photodegradable material
Plastic ring carriers, also known as six-pack rings or yokes, are a set of connected plastic rings used to package multi-packs of beverage cans, especially six-packs. They were invented in the 1960s and quickly replaced paper and metal-based holders. However, by the 1970s, environmentalists were concerned about their impact, and they became a symbol of harmful plastic waste, particularly marine debris that entangled wildlife.
In 1977, the US state of Vermont became the first to ban non-degradable ring carriers, and by 1991, 27 other states had followed suit. This was due to the recognition that these plastic rings were a form of marine litter and the finding that they persisted in the marine environment for decades, threatening marine life. The Environmental Protection Agency (EPA) proposed a biodegradability performance standard in 1993, and in 1994, the US Federal Regulation mandated that all plastic ring carriers be made of naturally degradable materials.
To comply with these regulations, manufacturers now use photodegradable materials for their ring carriers. Photodegradable materials break down when exposed to light, typically taking a few months to degrade. However, this process can still result in fragments and microplastics that may be consumed by animals. While photodegradable ring carriers reduce the risk of entanglement, they do not completely eliminate the issue of plastic waste and its impact on marine life.
Some companies have developed innovative alternatives to traditional plastic ring carriers. For example, in 2010, Saltwater Brewery created eco-friendly rings that are biodegradable and compostable. Other alternatives to plastic ring carriers include paperboard baskets and LDPE plastic can carriers, which have gained popularity as environmentally conscious alternatives.

However, photodegradable plastic still poses a threat to animals that ingest the microplastics formed during decomposition
Plastic ring carriers are used to hold together cans or bottles, commonly seen in six-packs of beverages. These plastic rings have come under scrutiny due to their environmental impact, particularly on marine life, leading to the development of photodegradable plastic as a potential solution. While this innovation is a step towards reducing plastic pollution, it does not eliminate all the risks associated with plastic degradation.
Photodegradable plastic is designed to break down into smaller pieces when exposed to sunlight. This process is intended to reduce the persistence of plastic waste in the environment. However, the issue of microplastics remains a concern. As photodegradable plastic decomposes, it breaks down into tiny microplastic particles that can be easily ingested by animals, both on land and in water. These microplastics can absorb toxic chemicals from the surrounding environment, becoming even more harmful.
When animals ingest these microplastics, it can lead to various health issues. The particles can release toxic chemicals in the digestive system, causing organ damage and disrupting hormonal balance. Additionally, the sharp edges of microplastics can cause internal injuries and inflammation. Over time, these particles can accumulate in the body, leading to health complications and potentially impacting the survival and reproduction rates of affected animals.
Furthermore, microplastics can enter the food chain, impacting a wide range of species. Animals that consume contaminated prey may also ingest the microplastics, leading to bioaccumulation. This means that higher up in the food chain, the concentration of microplastics can increase, posing greater risks to larger animals, including birds, marine mammals, and even humans. The impact of microplastics on the environment and animal health underscores the necessity of comprehensive solutions to address plastic pollution.
To mitigate the risks associated with photodegradable plastic, it is essential to focus on developing alternatives that are less harmful to the environment and wildlife. Biodegradable materials, such as natural fibers and bioplastics, offer promising solutions. Additionally, promoting recycling and responsible waste management practices can help reduce the amount of plastic waste that ends up in ecosystems. Public awareness and policy changes are also crucial in driving the adoption of eco-friendly alternatives and minimizing the use of single-use plastics.
While photodegradable plastic represents an effort to address the environmental concerns surrounding plastic ring carriers, it is not without its drawbacks. The formation of microplastics during decomposition continues to pose a significant threat to animal life. Addressing this issue requires a multifaceted approach, including the development of safer alternatives, improving waste management practices, and raising awareness about the responsible use and disposal of plastics. By prioritizing these actions, we can work towards minimizing the negative impact of plastic pollution on our planet's ecosystems and the animals that inhabit them.
