What You'll Learn
Specialist recyclers
Polystyrene, or PS plastic, is known for being hard to recycle. It is often used for disposable coffee cups, packing peanuts, coolers, and to-go food containers. It is also the foam plastic used for packing materials, Styrofoam cups, and trays.
If you are looking to recycle your PS plastic, you could try contacting specialist recyclers. Some companies now offer mail-in programs, where you can send your PS plastic waste to them. Given that PS plastic is often lightweight, postage costs should not be too high. You can check online recycling databases for recycler listings for foam products, as well as CD and DVD cases.
The Plastic Loose Fill Council provides a directory of places that take the fluffy peanuts used in packaging. The EPS (Expanded Polystyrene) Industry Alliance also provides a directory, including a list of recyclers that you can mail PS plastic to.
In some communities, PS plastic drop-off programs now exist, where you can take your foam waste to be recycled. It is worth calling your local solid waste management office to see if they have any information about such programs. Curbside recycling collection programs that accept polystyrene do exist, but they are rare.

Packaging and food containers
Plastic is a versatile material that has transformed the food industry. However, not all plastics are created equal, and their impact on human health and the environment varies. Understanding the types of plastics used in food packaging is crucial for members of the food industry to ensure the safety and longevity of their food products.
Polystyrene, identified as Plastic No. 6, is a lightweight and fragile plastic commonly used for packing materials and disposable food containers. It is also used in the food industry for items like fast-food packaging, cups, and trays. Polystyrene is easily recognized as the white foam blocks in packaging or packing peanuts. It is also commonly used in takeaway food packaging. Given that this type of plastic is so prevalent, it is helpful to know that polystyrene recycling is possible, but challenging. Generally, specialist recyclers will only take clean white polystyrene, and it must be free of any tape, plastic film, labels, loose parts, or glued-on cardboard.
In addition to polystyrene, other types of plastics are commonly used in food packaging. Polypropylene (PP), ranked at 5, is safe for food storage and is FDA-approved for food contact. It is a lightweight and sturdy plastic used for various food packaging, including yogurt cups, ketchup bottles, and microwaveable containers. PP containers offer excellent resistance to heat, UV light, and chemicals, making them suitable for tasks that require microwaving, freezing, or reheating. However, like other plastics, PP can release harmful chemicals when heated or exposed to sunlight for prolonged periods.
Other plastics used in food packaging include PET, LDPE, and HDPE. PET is lightweight, clear, and durable, making it suitable for water and carbonated beverage bottles, as well as packaging various food products such as peanut butter, salad dressings, and condiments. LDPE is pliable and see-through, commonly used for frozen food bags, bread bags, and food wraps. LDPE is safe for food contact, resistant to tearing, and demonstrates resistance to humidity, chemicals, and UV radiation. HDPE, on the other hand, is a sturdy and opaque plastic used in food packaging for items like milk jugs, yogurt containers, and cereal box liners.
While plastic has revolutionized the food industry, it is important to consider sustainable alternatives to reduce environmental impact. Biodegradable and compostable materials are being explored as alternatives to traditional plastic packaging. These solutions promote environmental sustainability, reduce carbon footprints, and ensure that today's food packaging does not become a problem for future generations.

Polystyrene foam
Polystyrene, otherwise known as Plastic #6, is a lightweight, rigid, and inexpensive plastic. It is often found in white foam blocks used for packaging and food containers. Polystyrene is also used for insulation, CD cases, and toys.
While polystyrene can technically be recycled, it is not always accepted by home recycling programs. This is because it is difficult to sanitise, and its lightweight composition means it easily becomes litter, where it can leach toxic chemicals.
If you wish to recycle polystyrene, you will need to find a specialist recycler where you can drop it off. It is important to ensure that the polystyrene is clean and free of any tape, plastic film, labels, loose parts, or glued-on cardboard. It should also be separated from other recycling and broken or cut into small pieces. Only white polystyrene is accepted at recycling facilities.
Some locations that accept polystyrene for recycling include:
- Dart Container Corporation, 1400 E. Victor Road, Lodi
- Cartons & Crates, 3250 California Blvd, Napa
- The UPS Store, 4225 Solano Ave, Napa
- All American Mail Center, 1370 Trancas Ave, Napa

Curbside recycling
Plastic #6, also known as polystyrene, is a common material found in disposable cutlery, food packaging, and foam products like cups, trays, and packing peanuts. While polystyrene can technically be recycled, it is not widely accepted by curbside recycling programs due to economic and logistical challenges. Many recycling facilities lack the capability to process this type of plastic. As a result, a large portion of polystyrene ends up in landfills or as environmental waste, contributing to pollution and microplastic contamination.
To properly recycle plastic #6 through curbside programs, it is essential to check your local guidelines and recycling symbols. Some curbside recycling programs do accept polystyrene, but they are rare. If your local program does not accept it, you can consider reusing polystyrene items or finding specialized recycling centers that accept them.
It is worth noting that some cities, like San Francisco, have banned the use of polystyrene foam for food service, effectively reducing its usage. However, this has often resulted in an increase in other types of food packaging waste. To recycle foam products, it is recommended to place them in a bag, squeeze out the air, and tie the bag before putting it in the trash to prevent pellets from dispersing.
While curbside recycling for plastic #6 is limited, there are other types of plastic that are more widely accepted. For example, PET or PETE (polyethylene terephthalate), commonly used for single-use bottled beverages, is easy to recycle and accepted by most curbside recycling programs, as long as it has been emptied and rinsed. HDPE (high-density polyethylene), found in milk jugs, detergent bottles, and some shopping bags, is another easily recyclable plastic that can be recycled up to 10 times and is accepted by most curbside programs.
In summary, while plastic #6 can be recycled, curbside recycling options are scarce due to logistical challenges. To ensure proper disposal, individuals should check their local guidelines and consider reusing or taking polystyrene items to specialized recycling centers. Additionally, transitioning to more readily recyclable materials can help reduce the environmental impact of plastic waste.

Reuse and upcycling
Type 6 plastic, also known as polystyrene (PS) or styrofoam, is commonly used for packaging materials, disposable coffee cups, packing peanuts, coolers, and food containers. While it is possible to recycle this type of plastic, it is not widely practised, and it is preferable to collect and reuse it. Here are some ideas for reusing and upcycling type 6 plastic:
- Collection and Reuse: Type 6 plastic can be collected and reused multiple times before recycling. You can designate a box specifically for collecting clean and intact pieces of polystyrene foam. Once you have a substantial amount, you can find creative ways to reuse it.
- Crafts and DIY Projects: Type 6 plastic can be used for various crafts and DIY projects. For example, you can cut polystyrene sheets into shapes and use them for art projects, model-making, or creating unique stamps for painting or printing. Just make sure to handle it with care as it can break into small pieces.
- Gardening and Agriculture: Type 6 plastic can be reused in gardening and agriculture applications. Cut polystyrene sheets or blocks into small pieces and use them as drainage fillers at the bottom of plant pots or containers. You can also use larger pieces as a base for raised garden beds or as a lightweight filler for large planters.
- Insulation and Packaging: Type 6 plastic has excellent insulation properties and can be reused for various insulation projects. For example, you can use it to line the walls or floors of a shed, garage, or attic to help regulate temperature. Additionally, you can reuse polystyrene packaging when shipping or mailing fragile items to ensure their safety during transit.
- Community Initiatives: Consider collaborating with your neighbours or local community groups to collect and upcycle type 6 plastic on a larger scale. By combining resources and ideas, you can explore more substantial upcycling projects, such as creating polystyrene-based art installations or community garden projects.
Remember, while type 6 plastic can be reused and upcycled, it is essential to minimise its use and disposal into the environment whenever possible. Always try to reduce your consumption of single-use plastics and opt for more sustainable alternatives when available.
