Plastic Straws: Degradation And Environmental Impact

Plastic straws are a major environmental hazard, particularly for marine life like turtles. These seemingly harmless items can end up in oceans due to improper waste disposal, and it can take a long time for them to deteriorate. While plastic straws can take up to 200 years to decompose, some estimates put the figure at 450 to 500 years. This is because plastic is a synthetic material, and microorganisms only feed on natural, organic matter. The good news is that alternatives to plastic straws exist, such as stainless steel, paper, or biodegradable options.

Plastic straws take 200 years to decompose

Plastic straws are a major contributor to pollution, with billions given out in cafes and restaurants or as part of takeaway meals every year. They are designed to be single-use, thrown away after just minutes of use, and they can take up to 200 years to decompose. This means that the plastic straws used today will still be around for our great-grandchildren to deal with.

The decomposition of plastic straws is a slow process of breaking down into smaller and smaller particles, known as microplastics. These microplastics can infiltrate the bodies of all living things, including humans, and have been linked to environmental pollution and health problems. As plastic straws degrade, they also release harmful chemicals such as bisphenol A (BPA).

The lightweight nature of plastic straws makes them easily blown out of rubbish bins, refuse vehicles, and landfill sites by the wind, ending up in waterways and the ocean. They are frequently found in beach clean-ups and are a top contributor to plastic marine debris globally. Plastic straws can harm marine life, such as seabirds, fish, sea turtles, manatees, and dolphins, when they get lodged in their noses, throats, and stomachs.

To reduce the environmental impact of plastic straws, many people are opting for reusable, non-plastic alternatives such as metal, bamboo, or glass straws. These options are more durable and environmentally friendly, although they may have higher initial greenhouse gas emissions during production. Some jurisdictions have also implemented "Skip the Straw" or "Straws Upon Request" laws to reduce plastic straw usage and promote alternatives.

Plastic straws are difficult to recycle

Plastic straws are a huge environmental concern. They take around 200 years to decompose, which means that the plastic straws in use today will still be around for our great-grandchildren to deal with. While they are technically recyclable, they are difficult to recycle due to their small size and flexibility. They often fall into the cracks and crevices of recycling machinery, jamming the equipment, and are therefore rejected by most recycling facilities. Even when they do make it to a recycling centre, they usually end up being sent to landfill or being incinerated.

Plastic straws are made from polypropylene, a material that is derived from oil. Although polypropylene can be recycled, most domestic recycling schemes do not accept it. Even when polypropylene is accepted, plastic straws are often too small to be detected by conveyor belts during the sorting process and are therefore missed.

There are some ways to recycle plastic straws properly. One method is to place the straws inside a larger polypropylene container, such as a takeaway container or margarine tub, so that they do not fall through the cracks during sorting. However, even with this method, the container might be manually sorted out and thrown away. Another option is to research whether your local area has the ability to recycle plastic straws, as some cities and recyclers may have the necessary equipment.

The difficulties in recycling plastic straws have led to a growing market for paper, metal, glass, and plant-based straws. However, these alternatives also have their drawbacks. Paper straws, for example, have been criticised for having a higher relative environmental impact than plastic straws due to the land use needed for the raw material (trees). They also degrade quickly in water and cannot be recycled. Metal straws, on the other hand, are durable and recyclable, but they require much more energy to produce than plastic straws, resulting in higher greenhouse gas emissions.

Overall, the best way to reduce the environmental impact of straws is to limit their use. Plastic straws are especially harmful due to their long decomposition time, but all types of straws have negative effects on the environment. Reusable straws are a more sustainable option, although they still require more energy to produce than single-use straws.

Plastic straws are a top 10 contributor to plastic marine debris

Plastic straws are a top contributor to plastic marine debris, ranking among the top 10 items found during ocean cleanups. Their small size, lightweight nature, and inability to be recycled make them a significant source of pollution. Plastic straws can end up as litter, clogging gutters and polluting waterways, streets, parks, and oceans, where they can persist for hundreds to thousands of years.

The issue of plastic straw recycling is complex due to their small, thin, and flexible design, which causes them to get stuck in recycling machines. As a result, most facilities do not accept plastic straws, leading to at least 97% of properly disposed-of straws ending up in landfills or being incinerated. This process contributes to global warming and the breakdown of straws into harmful microplastics.

Even though plastic straws only account for 0.2% of yearly plastic waste in the US by weight, they still add up to a significant amount, with an estimated 73,000 metric tons generated annually. Their impact on marine life is considerable, as they can sicken and kill seabirds, fish, sea turtles, manatees, dolphins, and other marine animals when ingested or lodged in their bodies.

To address the environmental impact of plastic straws, individuals can opt for reusable, non-plastic alternatives made from materials like metal, bamboo, glass, or plant-based sources. These options are more durable and environmentally friendly, reducing the number of single-use plastic straws that end up as litter or in landfills. Some cities, like Miami Beach, Florida, have even prohibited beachside restaurants from using plastic straws to reduce their environmental impact.

Plastic straws are ingested by marine animals

Plastic straws are a major source of pollution, and their ingestion by marine animals poses a significant threat to their health and survival. While plastic straws account for a relatively small proportion of yearly plastic waste in the US by weight, they still contribute significantly to marine pollution. They are often left on beaches, littered, or blown out of trash cans, and their small size and flexibility make them difficult to recycle. As a result, they end up in landfills, incinerated, or in the ocean, where they can persist for up to 200 years.

The ingestion of plastic straws by marine animals has severe consequences for their health and survival. Plastic straws can get lodged in the noses, throats, and stomachs of seabirds, fish, sea turtles, manatees, dolphins, and other marine creatures, causing sickness and death. The issue is widespread, with 100% of turtles studied found to have eaten plastic, and it is projected that by 2050, 99% of seabird species will have ingested plastic, with a mortality rate of up to 50%.

As plastic straws break down into microplastics, they become even more harmful to marine life. Microplastics can infiltrate the bodies of marine animals, including fish that are consumed by humans. This means that humans are also indirectly ingesting microplastics, as evidenced by the presence of plastic in 94% of US tap water and shellfish. The use of single-use plastic straws contributes to this issue, and while paper straws are an alternative, they also have environmental impacts and are not always a practical solution.

To address the problem of plastic straws in the ocean and their impact on marine life, individuals can take several actions. People can choose to refuse single-use plastic straws, opting for reusable alternatives made from metal, bamboo, or glass. Additionally, supporting "Skip the Straw" or "Straws Upon Request" laws can help reduce plastic pollution and encourage the use of alternative options. By making these simple changes, individuals can play a significant role in protecting marine animals from the harmful effects of plastic straw ingestion.

Plastic straws are made from polypropylene or polystyrene

Plastic straws are a major contributor to pollution. They are small and lightweight, which makes it easy for them to end up as litter, clogging gutters and polluting waterways, streets, parks, and oceans. They are also non-recyclable, so those that are discarded will end up in landfills and incinerators, releasing harmful chemicals into the air and soil. Plastic straws can take up to 200 years to decompose, and during this time, they can cause the death of marine animals through ingestion or entanglement.

Most plastic straws are manufactured from polypropylene, a polymer made using propylene gas, which is a fuel made up of hydrogen and carbon atoms. The gas undergoes a chemical reaction called polymerization, where many propylene molecules form one very long chain called polypropylene. Polypropylene is a commonly used polymer, and most plastics are polymers. Polypropylene is also used to make toothbrushes, which, like plastic straws, can take up to 500 years or more to decompose.

Some plastic straws are made from polystyrene, a polymer that contains styrene, a likely human carcinogen. Polystyrene is also used for throwaway drink cups, takeaway food containers, and disposable cutlery. It comes in a variety of hard forms, as well as soft foam types, commonly referred to as "Styrofoam". Polystyrene can cause eye, nose, and throat irritation and can affect the nervous system. It can also leach styrene, a neurotoxin that has been linked to headaches, fatigue, and other health problems.

The use of plastic straws has faced a backlash, with a growing market for paper, metal, glass, and plant-based alternatives. While paper straws may not be as durable as plastic ones, they are more environmentally friendly and degrade quickly in water. Metal and glass straws are also reusable and safer alternatives to plastic straws, although they have a higher environmental impact during production.
