Berkeley's recycling practices have been under the international spotlight recently, with the city committed to recycling. The city provides municipal collection services for multi-family garbage and organics, and recycling services for multi-family complexes with 9 or fewer units. Plastic containers are accepted at Berkeley Recycling, but they must be clean, empty, and donated. Plastic #4 can be recycled into shipping envelopes, paneling, tiles, plastic lumber, trash can liners, and trash cans. Plastics with a 1, 2, or 5 are more recyclable, while Number 3 plastics, or PVC materials, are typically not recyclable in Berkeley.

What You'll Learn
Plastic containers
It is important to note that Berkeley Recycling cannot process plastic items smaller than 2.5 inches, such as coffee cup lids and bottle caps, as they may not be captured by the sorting line and end up in landfills. Rigid plastics are preferred over soft plastics, and it is recommended to reuse items when possible.
When recycling plastic containers, it is essential to rinse, clean, and dry them to prevent contamination during transportation and storage. This is because any residual food or liquid can cause mold and decay, degrading the quality of the entire stock.
To recycle plastic containers in Berkeley, residents can separate their recyclables and place their cans, bottles, jugs, and tubs on one side and paper and cardboard on the other for curbside pickup. They can also take their plastic containers to the Berkeley Recycling Center on Second Street and deposit them in the appropriate bins.
It is worth noting that some plastics are more recyclable than others. Plastics with a 1, 2, or 5 are more recyclable and include soda and water bottles, detergent bottles, and yogurt tubs. Number 3 plastics (PVC materials) are typically not recyclable in Berkeley, and number 6 plastics (Styrofoam) cannot be recycled.

Sorting plastic
The first step in sorting plastic is to separate different types of plastic from each other. Plastic items are often marked with a number from 1 to 7, which helps identify the type of plastic they are made of. These numbers are not direct indicators of recyclability but can guide consumers in making more sustainable choices. Plastics with a 1, 2, or 5 are more commonly recyclable and include items like soda and water bottles, detergent bottles, and yogurt tubs. Number 1 plastics, or PET plastics, are recycled domestically, while all other plastics from Berkeley are recycled overseas. Number 2 plastics are natural-coloured HDPE plastics. Number 3 plastics, or PVC materials, are typically not recyclable in Berkeley and must be separated from other plastics. Number 4 plastics, or LDPE plastics, are lightweight and used for items like shopping bags, bread bags, and squeezable bottles. Number 6 plastics are primarily Styrofoam and are not recyclable. The mixed "other" category, number 7, also does not contain recyclable materials.
In addition to sorting by type, it is important to sort plastic items by size and colour. Large rigid plastics, such as buckets, crates, and lawn chairs, can be dropped off at the Berkeley Recycling Center. Small items, like coffee cup lids and bottle caps, may not be captured by the sorting line and often end up in landfills. To avoid this, it is recommended to collect small items over time and recycle them together. For example, small pieces of aluminium foil can be balled up before recycling. Plastic bottles and containers should be pre-sorted by colour (clear, brown, and green) to facilitate the recycling process.
Preparing Plastic for Recycling
Properly preparing plastic items for recycling is crucial. All containers, including plastic, glass, and metal, must be rinsed, cleaned, and dried to remove any residual food or liquid. This ensures that the items are virtually free of contaminants. Additionally, it is important to separate CRV (California Redemption Value) and non-CRV plastic items. CRV items include carbonated soda, water, and juice bottles, as well as spring water bottles and jugs. These items can be loaded into the designated "Plastic Bottles" conveyor at the Berkeley Recycling Center.
Other Considerations
It is important to note that not all plastic items can be recycled. Some plastics, such as thin plastic bags, are too thin and flexible to be recycled with hard plastics and can cause issues with recycling machinery. It is recommended to dispose of these items properly to prevent them from becoming litter. Additionally, wish-cycling, or recycling low-quality items with the hope that they will be processed, should be avoided. Instead, focus on reducing and reusing items before recycling them.

Plastic numbers
Plastic items are assigned a number from 1 to 7, which indicates the type of plastic resin the item is made of. These numbers are often found within a small triangle symbol, which is known as a resin identification code. This code is used to help recycling plants sort plastics by type.
Plastic #1 (PET)
Plastic #1, also known as PET or PETE (polyethylene terephthalate), is commonly used for soda and water bottles, detergent bottles, and some food containers like peanut butter jars. It is one of the most commonly recycled plastics and is accepted in most recycling programs, including Berkeley's.
Plastic #2 (HDPE)
Plastic #2, or HDPE (high-density polyethylene), is typically used for making plastic bottles, like milk jugs, as well as some rigid containers. It is also widely accepted by recycling programs, including Berkeley, and is considered more valuable than some other plastics.
Plastic #3 (PVC)
Number 3 plastics, or PVC (polyvinyl chloride), are not commonly recycled in Berkeley and require separation from other plastics. These plastics are often used for things like plumbing pipes, shower curtains, and outdoor furniture.
Plastic #4 (LDPE)
Plastic bags are often labelled as plastic #2 or #4, but they are usually too thin to be recycled with hard plastics and can cause issues in recycling machinery. Plastic #4 is lightweight and flexible, used for shopping bags, bread bags, dry cleaning bags, and some squeezable bottles. While it can be recycled, it is not as widely accepted as #1 or #2 plastics, but it can be recycled into items like shipping envelopes and trash cans.
Plastic #5
Plastics with a #5 number are generally considered more recyclable and include items like soda and water bottles and yogurt tubs.
Plastic #6 (Polystyrene/Styrofoam)
Number 6 plastics are essentially Styrofoam and are not recyclable in most programs, including Berkeley's.
Plastic #7 (Other)
The #7 category is a mixed "other" category, which means it includes a variety of different plastics that don't fit into the previous categories. Items in this category generally do not contain recyclable materials.
It is important to note that, while these numbers can help consumers identify which plastics to avoid or prefer when shopping, they do not always indicate recyclability. For example, a triangle on the bottom of a plastic container does not necessarily mean that it can be recycled. Additionally, it is always recommended to check with your local recycling program, like Berkeley Recycling, to understand their specific guidelines and restrictions.

Plastic bags
Berkeley Recycling does not accept plastic bags for recycling. Plastic bags should be reused or shared with friends or neighbours who could use them for pet waste or other purposes. After reuse, they should be placed in municipal waste and sent to a landfill.
There are a few remaining buyback centres in Berkeley, one of which is located at Berkeley Recycling and is open six days a week. The program is subsidised through the California Redemption Value (CRV) program. Individuals can bring CRV items (aluminum, glass, and plastic bottles) and sell any CRVs smaller than 24 ounces for five cents and anything 24 ounces or greater for 10 cents. The centre also has a donation box where it takes non-CRV plastics, like mouthwash bottles, which can also be placed in curbside bins.
Berkeley Recycling accepts plastic containers for donation only. These must be clean and empty. Typically, these include clear clamshells, drinking cups, yogurt and dairy tubs, and clear food takeout containers. Berkeley Recycling does not accept plastic containers with food soil, as they are very labour-intensive in recycling centres.
Berkeley Recycling also accepts mixed rigid plastics like laundry hampers, buckets, bus tubs, and plastic chairs. These can be dropped off at the transfer centre. However, they cannot take plastics that are integrated with other materials, like a metal-framed chair with plastic armrests and backing.

Plastic recycling challenges
Plastic recycling in Berkeley comes with a unique set of challenges. While the city is committed to recycling plastics, certain types of plastics pose problems and are not as straightforward to recycle as others.
One of the main challenges is the variety of plastics that exist. Plastics are categorized by numbers, and not all numbered plastics are recyclable in Berkeley. For instance, Number 3 plastics, or PVC materials, are typically not recyclable in the city and need to be separated from other plastics. Number 4 plastics, which include thin, flexible shopping bags, bread bags, and dry cleaning bags, are also problematic as they are too thin to be recycled with hard plastics and can get caught in the recycling machinery. Number 6 plastics, which are essentially Styrofoam, also cannot be recycled.
The market for recycled plastics is also constantly changing, and incorrect labels on plastic products can confuse residents who want to recycle responsibly. For example, a triangle on the bottom of a plastic container does not necessarily mean that it can be recycled. Additionally, China's decision to no longer accept low-quality recyclables from the United States has impacted the global recycling market, including Berkeley's local recycling practices.
Another challenge is the size of plastic items. Small items such as coffee cup lids and bottle caps may not be valuable in the current market, and their small size means they can fall through the sorting line and end up in landfills. Similarly, plastic items smaller than 2.5 inches cannot be processed by Berkeley Recycling and must be disposed of in other ways.
Lastly, the contamination of recycling streams is a significant issue. Plastic containers must be clean and empty before they can be recycled. Any residual food or liquid can contaminate the entire batch of recyclables, rendering them non-recyclable. This highlights the importance of consumer education on proper cleaning and separation of recyclables.
