California has a reputation for high pollution rates and waste, with packaging making up 50% of waste in California landfills by volume. To combat this, California voters upheld the nation's first state ban on single-use plastic bags in 2016. However, recycling plastic can be confusing, with various types of plastics and local variations in recycling programs. In Los Angeles, for example, plastics numbered 1, 2, and 5 are allowed in blue recycling bins, while plastics numbered 3, 4, 6, and 7 are not. This article will explore the recyclability of different plastics in California and provide guidelines for responsible waste management.

What You'll Learn
Plastic bags and single-use plastic banned in California
California has been at the forefront of the battle against plastic waste. In 2016, California voters upheld the nation's first state ban on single-use plastic bags, aligning state law with many local ordinances to cut plastic waste. The state also filed a lawsuit against oil and gas giant ExxonMobil, a leading producer of the polymers used to make single-use plastics.
The state's original ban on plastic bags didn't go as planned and, in some cases, made things worse. An evaluation found that municipal systems were unable to recycle plastic bags, and the soft material caused equipment jamming at recycling centres, leading to costly repairs. However, California has persisted with its efforts, and in 2024, it joined 10 other states with restrictions in place on single-use plastic bags.
The new law places the onus on the plastics industry rather than the consumer. It requires all packaging in California to be recyclable or compostable by 2032, cutting plastic packaging by 25% and mandating that 65% of all single-use plastics be recycled. The bill also requires the industry to create a $5 billion fund to help low-income communities disproportionately affected by plastic waste.
The state's recycling authority, CalRecycle, has released a list of materials considered recyclable. Plastics marked with numbers 1, 2, and 5 are deemed recyclable, especially when in rigid forms like milk jugs, water bottles, jars, and yogurt tubs. However, plastics marked with numbers 3, 4, 6, and 7 are no longer allowed in LA's blue recycling bins, even if they include a recycling symbol.
California's efforts to reduce plastic waste extend beyond just bags. The state has implemented packaging programs that manage multiple materials, including plastics, and a Beverage Container Recycling Program that includes some plastic beverage containers. Consumers pay the California Refund Value (CRV) on eligible containers, which is refundable when they are returned. Additionally, California processors and manufacturers may receive incentive payments for recycled CRV plastic used in new products.

Plastic 1,2,5 are recyclable
Plastic waste is a pressing issue, and California is taking steps to address it through various programs and initiatives. One of the most significant steps was the ban on single-use plastic bags in 2016, which was a landmark decision to reduce plastic waste. Additionally, California has implemented a beverage container recycling program that includes specific plastic beverage containers.
When it comes to plastic recyclability, not all types of plastic are created equal. In Los Angeles, the city's sanitation department has recently updated its guidelines on which plastics can be placed in the blue recycling bins. Clean and empty plastics marked with the numbers 1, 2, and 5 are accepted in the blue bins and can be successfully recycled.
Plastic type 1, often known as polyethylene terephthalate or PET, is commonly used for soda and water bottles, including their lids and caps. This type of plastic is widely accepted in recycling programs and can be effectively recycled into new products.
Plastic number 2, or high-density polyethylene (HDPE), is used in various products, including laundry soap, shampoo, and lotion bottles, as well as milk jugs. This type of plastic is also recyclable and can be processed into new materials.
Plastic 5, identified as polypropylene or PP, is used for retail food containers like yogurt, butter, and margarine tubs. It's important to note that black microwave meal trays made of PP are not recyclable. Still, the standard PP containers are accepted in recycling programs.
By separating these plastics and placing them in the appropriate recycling bins, individuals can contribute to reducing plastic waste and promoting the reuse of these materials in new products. It's essential to stay informed about local recycling guidelines, as they may vary, and to adopt a "reusable, not disposable" mindset whenever possible.

Plastic 3,4,6,7 are non-recyclable
Plastic products are usually stamped with a number inside a triangle, known as a resin code, which indicates the type of resin or plastic used in the product. These numbers, from 1 to 7, are used to help recycling plants identify different types of plastics. However, the presence of a resin code does not necessarily mean that the product can be recycled.
Plastics numbered 3, 4, 6, and 7 are non-recyclable and should be disposed of in the trash. Plastic 3, or polyvinyl chloride, is a soft and flexible plastic used for clear food wrapping, teething rings, and kids' and pet toys. Plastic 4, or low-density polyethylene, is used for shrink wrap, dry-cleaning bags, plastic shopping bags, squeezable bottles, and bread packaging bags. These bags should not be put into recycling bins as they can get tangled in the equipment at recycling facilities. Plastic 6, or polystyrene, is used for disposable cups, plastic utensils, food containers, and foam packaging material. Polystyrene is not generally recyclable and accounts for about 35% of US landfill material. It easily breaks apart, often ending up inside marine animals and on beaches. It has also been linked to human health issues, especially when heated. Plastic 7, or biodegradable/compostable plastic, is used for packaging, cutlery, and food containers. It often consists of multiple plastic types or other types of plastic that are hard to recycle.

Plastic 1 includes soda and water bottles
Plastic recycling can be confusing, but it's important to know what plastics can be recycled in California to reduce waste. Almost every plastic bottle or container has a recycling symbol numbered 1-7, usually stamped at the bottom, and these numbers indicate the type of plastic used in each product. However, not all plastics are equally recyclable, and some are safer than others.
Plastic #1, or PET (polyethylene terephthalate), is one of the most commonly used plastics in consumer products and is found in soda and water bottles, as well as some salad dressing containers, mouthwash bottles, and peanut butter containers. It is intended for single-use applications, as repeated use increases the risk of leaching and bacterial growth. PET plastic is difficult to decontaminate, and proper cleaning requires harmful chemicals. It is important to note that these #1 plastic bottles should be recycled but not reused. To reduce the use of PET plastic, it is recommended to switch to reusable beverage containers and replace disposable food packaging with reusable alternatives.
In California, plastics marked with the numbers 1, 2, and 5 are deemed recyclable, especially when in rigid forms like milk jugs, water bottles, jars, and yogurt tubs. This means that Plastic #1 is widely recyclable in California and can be placed in the blue recycling bins, as long as they are clean and empty.
The City of Hayward's website offers additional guidance on plastic recycling. It recommends that residents empty their plastic containers before recycling and use the StopWaste's re:source tool if they are unsure about how to dispose of an item within their specific zip code.
It is worth noting that certain plastics, such as plastic bags and disposable cutlery, are no longer allowed in LA's blue recycling bins. This includes Plastic #3, #4, #6, and #7, as they cannot be recycled, even if they include a recycling symbol.

Plastic 2 includes shampoo bottles and milk jugs
Plastic recycling can be a confusing affair, with different types of plastics requiring different disposal methods. In California, the state's recycling authority, CalRecycle, has deemed plastics marked with the numbers 1, 2, and 5 as recyclable. This includes rigid forms like bottles and jugs, specifically milk jugs, water bottles, and yogurt tubs.
Plastic number 2, or high-density polyethylene (HDPE), is one of the most commonly recyclable plastics. It is accepted in LA's blue recycling bins, provided it is clean and empty. Plastic 2 is often used for containers like shampoo bottles, lotion bottles, detergent bottles, and milk jugs. These containers usually have a handle and a wider opening than the base.
To identify Plastic 2, look for the chasing arrow symbol with the number 2. Before placing these plastics in the recycling bin, ensure they are empty, clean, and dry. This is important as any residual product can contaminate the rest of the batch during the recycling process.
In California, recycling single-use plastic items is crucial to reducing waste. Packaging, for example, makes up 50% of waste in California landfills by volume. By recycling Plastic 2 items, such as shampoo bottles and milk jugs, Californians can play their part in reducing landfill waste and moving towards a more sustainable future.

Frequently asked questions
In California, plastics numbered 1, 2, and 5 are deemed recyclable. This includes items like milk jugs, water bottles, jars, and yogurt tubs. However, it's important to note that the recyclability of these plastics can vary based on their specific form and your specific location within California.
The recyclability of plastics depends on the local recycling infrastructure and capabilities. Different types of plastics require different processing methods and facilities, and not all locations have the necessary equipment or programs in place. Additionally, some plastics may be deemed non-recyclable due to the challenges of effectively recycling them or the presence of alternative, more sustainable options.
One challenge is that many single-use plastic items are not recycled even if they carry a recycling symbol, leading to a high rate of plastic waste in the state. Additionally, there are varying rules and guidelines for recycling across different counties, cities, and towns within California, making it confusing for residents to know what can and cannot be recycled. To address these issues, California has implemented initiatives such as Senate Bill 54, which aims to reduce single-use plastic waste and increase recycling rates by setting specific targets.
