Plastic is everywhere, and while recycling is the best step when plastic cannot be avoided or reused, it can be a complicated process. Less than 10% of plastic waste has ever been recycled. One of the barriers to recycling is a lack of awareness of the seven plastic recycling symbols, each of which represents a different type of plastic and has distinct recycling instructions. Plastic #2, or HDPE, is considered one of the safest types of plastic and is widely recycled.
| Characteristics | Values |
|---|---|
| Plastic type | HDPE (High-density polyethylene) |
| Resin code | 2 |
| Recyclability | Recyclable |
| Common uses | Milk jugs, shampoo bottles, detergent bottles, plastic bags, newspaper bags, bread bags, grocery bags, etc. |

What You'll Learn
HDPE plastics are recyclable and marked with #2
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. Each number corresponds to a different type of plastic. HDPE plastics are recyclable and marked with #2. They are used to make milk jugs, detergent containers, oil bottles, shampoo bottles, and cleaning product containers. HDPE is one of the safest plastics to use and is fully recyclable.
Most recyclers accept plastics #1 and #2, while plastics #3 to #6 are more difficult to recycle, and some recycling centers do not process them. Plastic #7 is even more challenging to recycle and is almost always excluded.
It is important to note that not all plastic bags are recyclable, but some companies and recycling centers are investigating how to recycle them due to their harmfulness to the environment. LDPE, or low-density polyethylene, is a flexible plastic with many applications. While it has not been accepted through most American recycling programs, an increasing number of communities are starting to accept it. LDPE is often used for plastic bags, Ziploc bags, and tote bags.
To recycle LDPE, it is recommended to clean and dry any residue from the inside and outside of the bag before bringing it to a drop-off site. Similarly, HDPE plastic shopping bags can often be returned to stores for recycling, but they should also be fully cleaned and dried before recycling.

LDPE plastics are marked #2 but not widely recycled
LDPE, or low-density polyethylene, is a flexible plastic marked with #2 and used in a variety of applications, including plastic bags, Ziploc bags, shopping bags, tote bags, and shrink wraps. While LDPE is marked with the #2 recycling symbol, it has historically not been widely accepted by American recycling programs due to its flexible nature, which can cause it to get tangled in recycling equipment. However, more and more communities are starting to accept LDPE for recycling.
The recyclability of LDPE plastics marked #2 depends on your location and the capabilities of your local recycling facilities. In some areas, LDPE plastics can be recycled through curbside programs, while in other areas, they may need to be returned to stores or specific drop-off locations for proper recycling. It is important to check with your local waste management guidelines or recycling centers to understand their specific rules and capabilities for recycling LDPE plastics marked #2.
One challenge with recycling LDPE plastics is that they often require specialized handling due to their flexible and soft nature. They can get tangled in recycling equipment, so proper disposal is crucial. Before recycling LDPE plastics, it is essential to clean and dry any residue from the inside and outside of the material, as contamination can hinder the recycling process.
To reduce the environmental impact of LDPE plastics marked #2, it is recommended to reuse and repurpose them safely whenever possible. For example, plastic bags can be reused for shopping or storing items, and Ziploc bags can be washed and reused multiple times. Additionally, some companies and recycling centers are actively working on finding alternatives and improving their processes for recycling plastic bags and LDPE materials due to their harmfulness to the environment if not disposed of properly.

Recycling #2 plastics: clean and dry before recycling
Plastic marked with a 2 is HDPE plastic, which stands for high-density polyethylene. This is a hard, usually opaque plastic used to make items like milk jugs, shampoo bottles, detergent bottles, and plastic shopping bags. HDPE products can be recycled and are accepted by most curbside recycling programs.
To recycle #2 plastics, it is important to ensure they are clean and dry. This is because liquids and food left in containers can contaminate not only other items in your recycling cart but also any other recycled materials they come in contact with. While one ketchup bottle or a milk carton might not make a huge difference, if everyone includes recyclables with remnants in them, the cumulative effect can ruin otherwise perfectly recyclable items. These contaminated items will likely end up in a landfill instead of being recycled.
To clean your #2 plastics, rinse out any remaining liquids, especially if they are oily. For sticky containers, use a rubber spatula to eliminate the gunk, or if you have a dishwasher, place the containers in an empty corner before running a load. If there are only a few remnants left in the container, consuming them before recycling is also an option. While recyclables should be clean, they don't need to be spotless.
It is also important to separate different types of plastics before recycling, as some require specialized handling. For example, plastic bags, which are often made of LDPE, are categorized as film plastics and usually can't be recycled in a curbside bin. However, some stores will collect and recycle them.

Plastic bags are often LDPE but not widely recycled
Plastic bags are often made from low-density polyethylene (LDPE), which is a flexible plastic with a wide range of applications. LDPE is marked as #4 when it comes to plastic recycling codes, and it is used in plastic bags, plastic wrappings, and cling film.
Despite being commonly used, LDPE is not widely recycled. This is due to the fact that most recycling facilities do not have the necessary equipment or personnel to process it. LDPE is flexible and bends easily, which means it can get caught in recycling machinery and cause jams. This results in increased downtime and labour costs for recycling programs, making it less profitable for governments to accept this type of plastic.
However, there are still ways to recycle LDPE products, including plastic bags. Some communities are starting to accept LDPE through their recycling programs, so it is worth checking with your local sanitation or recycling plant to see if they accept this material. Additionally, many grocery stores and retailers have collection bins for plastic bags, allowing for proper recycling.
It is important to note that when recycling plastic bags, they should be clean and dry, free of any food residue, stickers, staples, or receipts. Reusing plastic bags at home, such as for wrapping or carrying items, is also an option to reduce waste.

Recycling #2 plastics: check your town's legislation
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. The number inside the triangle is what determines whether a plastic product can be recycled or not.
#2 plastic, also known as high-density polyethylene (HDPE), is one of the most common types of plastic and is generally accepted by most recyclers. It is used to make milk jugs, shampoo bottles, cleaning product containers, and detergent bottles. These products are safe to be recycled and are accepted in standard recycling bins. However, it is always important to check your town's legislation and rules for recycling to ensure that #2 plastic is accepted in your area. Some municipalities may have specific guidelines or restrictions on recycling #2 plastics.
While #2 plastic is widely recyclable, there are still some considerations to keep in mind. It is essential to ensure that the plastic products are clean and dry before placing them in the recycling bin. This is especially important for products that have had contact with food or other residues, as mentioned in the How2Recycle guidelines. Additionally, some communities may have specific drop-off locations or programs for recycling #2 plastics, so it is worth checking with your local waste management authority or visiting websites like EARTH911.COM for state-specific recycling information.
It is also worth noting that not all plastic products are created equal when it comes to recyclability. While #2 plastic is widely accepted, other types of plastics, such as #3, #6, and #7, may be more challenging to recycle. These plastics may contain potentially harmful chemicals like BPA, which can disrupt hormones and endocrine function. Therefore, it is generally recommended to avoid or minimize the use of these plastic types whenever possible and to check with your local guidelines to understand how to properly dispose of them.
By understanding the resin codes on plastic products and staying informed about your town's legislation on recycling, you can ensure that you are properly recycling #2 plastics and doing your part for the environment. Remember, recycling is just one part of the solution, and it is also essential to reduce plastic consumption and opt for reusable alternatives whenever possible.
