What You'll Learn
Plastic recycling symbols and their meanings
Plastic recycling is a complex process, and understanding the various symbols and their meanings is essential for proper waste management. The recycling symbols on plastic items indicate the type of plastic and provide specific recycling instructions. These symbols are known as resin identification codes and were introduced by the Society of the Plastics Industry in 1988. There are seven primary plastic recycling symbols, numbered from 1 to 7, each representing a different type of plastic with distinct recycling requirements.
Symbol 1, with the acronym PETE or PET, represents polyethylene terephthalate. This type of plastic is commonly used for single-use food and drink packaging, such as soda and water bottles, salad dressing bottles, and peanut butter containers. It is widely accepted by curbside recycling programs and can be recycled into new containers, furniture, carpet fibres, and winter jackets.
Symbol 2, denoted as HDPE, stands for high-density polyethylene. This plastic is widely used for containers like milk cartons, cleaning agents, detergents, and washing soap bottles due to its low weight and high strength. HDPE is easily recyclable and can be transformed into pipes, oil bottles, pens, and detergent bottles.
Symbol 3, represented by the letter "V," corresponds to PVC or polyvinyl chloride. PVC is found in bubble foils, trays for sweets and fruit, and expanded PVC foam board for commercial applications. While PVC is rarely recycled, it can occasionally be repurposed for speed bumps, roadway gutters, and cables.
Symbol 4, LDPE, stands for low-density polyethylene, a flexible plastic used in shopping bags, highly resistant sacks, and crushed bottles. LDPE is not commonly recycled but can be converted into floor tiles and shipping envelopes. However, some communities are starting to accept LDPE through their recycling programs.
Symbol 5, often found on polypropylene products, poses a recycling challenge. Polypropylene is rigid, tough, and resistant to moisture and chemicals. It is commonly used for ketchup bottles, kitchen containers, straws, and medicine bottles. While polypropylene was once accepted by most curbside recycling programs, the market for it has shrunk since China stopped importing America's recyclable waste in 2018.
Symbol 6, PS, represents polystyrene, often referred to as "Styrofoam" in the US. This lightweight plastic is frequently used for egg cartons, disposable cups, dinnerware, and packaging materials like packing peanuts.
Symbol 7 plastics, which include acrylic and polycarbonate, should be confirmed with your local recycling program. Acrylic is used for food storage containers, signs, shelving, and showcases due to its strength and transparency.
It is important to note that the presence of the “chasing arrows” symbol on a plastic product does not necessarily indicate that it is recyclable. Instead, the small number within the triangle helps identify the type of plastic used, guiding us towards the appropriate disposal method.

Plastic waste management in the US
Plastic waste management is a pressing issue in the US, with the country facing challenges in dealing with its own plastic waste and contributing to global plastic pollution. The US has historically relied on other countries, such as China, to process its recycled plastic. However, in 2018, China tightened restrictions on the import of contaminated plastic waste, forcing the US to confront its domestic recycling infrastructure.
The US Environmental Protection Agency (EPA) plays a crucial role in plastic waste management through its various programs and initiatives. The EPA measures and monitors the generation, recycling, composting, combustion with energy recovery, and landfilling of plastic materials in municipal solid waste (MSW). It also releases an annual report, "Advancing Sustainable Materials Management: Facts and Figures," which provides comprehensive information on MSW trends, including plastic waste.
One of the key challenges in plastic waste management in the US is the complexity of plastic recycling. There are seven plastic recycling symbols, each representing a different type of plastic with distinct recycling instructions. This lack of standardization can confuse consumers, leading to improper recycling and contamination. Number 5 plastics, for instance, were widely accepted in curbside and drop-off recycling centers before China's policy change but now face recycling challenges in the US.
To address these issues, the EPA has implemented several programs. The Sustainable Materials Management (SMM) program promotes the efficient use and reuse of materials, partnering with businesses, governments, and nonprofits to reduce waste and incorporate sustainable practices. The WasteWise program is another voluntary initiative that engages stakeholders to improve waste management. Additionally, the EPA has released the "National Strategy to Prevent Plastic Pollution," focusing on eliminating plastic pollution in the environment.
At the community level, organizations like Earth911 provide resources to help individuals recycle responsibly. They offer information on local recycling options and mail-in programs for challenging-to-recycle plastics like polypropylene. TerraCycle, another company, offers recycling programs for various products, including fee-based boxes that accept #5 plastics.
While these efforts are a step in the right direction, the US still faces significant challenges in plastic waste management. The country must improve its domestic recycling infrastructure, reduce its reliance on other nations for processing recycled materials, and increase public awareness about proper plastic recycling practices to ensure a more sustainable future.

How to recycle #5 plastics
Number 5 plastics are hard and heat-resistant, and they are used in various products, including prescription medicine bottles, yoghurt cups, hummus tubs, single-use cutlery, and some packaging for personal care products. They are also used in the lids of single-use drink bottles and many single-use laboratory and medical supplies.
Recycling number 5 plastics can be challenging, and they are considered hard-to-recycle plastics. Before 2018, number 5 plastics were widely accepted in both curbside and drop-off recycling centres. However, after China's National Sword policy was introduced in 2018, which stopped accepting contaminated plastic waste for recycling, recycling number 5 plastics became more difficult.
- Check with your local solid waste district or local programs to find out what options are available in your region. Some areas may have curbside or drop-off recycling programs that accept number 5 plastics.
- Look for specialised recyclers like TerraCycle, which offers programs to recycle almost any type of waste, including number 5 plastics. They have free and fee-based programs, with the smallest sizes costing between $92 and $241.
- Mail your number 5 plastics to a recycler called Preserve, which has a program called Gimme 5 specifically for these plastics.
- Reuse or upcycle your number 5 plastic containers. For example, you can use yoghurt containers as organisers or make suncatchers out of clear lids.
- Contact the manufacturer of your favourite products packaged in number 5 plastics and request that they use earth-friendly packaging instead.
It is important to note that the recycling symbol on plastic products does not always indicate that the item can be recycled in your community. Always rinse your recyclables once or twice to prevent contamination, but avoid spending too much time and water on making them spotless.

Environmental impact of plastic waste
Plastic waste has a significant impact on the environment, with far-reaching consequences for both natural and human ecosystems. The production, use, and disposal of plastics contribute to a range of environmental issues, including pollution, habitat destruction, and climate change.
One of the primary concerns regarding plastic waste is its persistence in the environment. Unlike other materials, plastic does not biodegrade and can take up to 1,000 years to break down. As a result, plastic waste accumulates in landfills, oceans, and other natural habitats, leading to pollution and degradation of these environments. According to the United Nations Environment Programme, less than 10% of plastic waste generated worldwide has ever been recycled. This means that the majority of plastic waste ends up in landfills or as mismanaged waste, with a significant amount also leaking into aquatic ecosystems.
The impact of plastic waste on the marine environment is particularly concerning. Marine species are at risk of ingesting plastic, suffocating, or becoming entangled in plastic pollution. Research indicates that more than 1,500 species in marine and terrestrial environments are known to ingest plastics. In addition, microplastics (plastic particles ranging in size from 5mm to 1 nanometer) and nanoplastics (smaller than 1 micrometer) have been found in every ecosystem on the planet, including the Antarctic tundra and tropical coral reefs. These tiny plastic particles can have harmful effects on wildlife, with potential consequences for human health as well. According to the US EPA, microplastics have been detected in human livers, kidneys, and placentas, raising concerns about potential health risks.
The production and disposal of plastics also contribute to climate change. The manufacturing of plastic is an energy-intensive process, often relying on fossil fuels such as crude oil. In 2019, the production and use of plastics generated 1.8 billion metric tons of greenhouse gas emissions, accounting for 3.4% of the global total. Additionally, the improper disposal of plastic waste can lead to the release of toxic chemicals, further contributing to environmental degradation and health risks.
To address the environmental impact of plastic waste, systemic reforms and individual behavioural changes are necessary. Governments and industries need to encourage innovation, improve waste management infrastructure, and provide incentives for reducing plastic use and promoting reusable alternatives. At the individual level, people can make a difference by avoiding single-use plastic products, reusing and repurposing plastic items whenever possible, and properly recycling or disposing of plastic waste.
