Clamshell packaging is recyclable but not all recycling programs accept it
Clamshell packaging is a popular choice for food items and consumer goods due to its lightweight, durable, and clear structure. It is often used for fresh produce, baked goods, and retail products. While clamshell packaging is technically recyclable, not all recycling programs accept it. This is mainly because clamshells are challenging to process along with other plastics due to their different bulk density and strong adhesive labels.
The bulk density of clamshells differs from that of PET bottles, making it difficult to process them together. When mixed with other plastics during recycling, clamshells can contaminate the final PET bales, reducing their purity and market value. Additionally, the strong adhesive labels on clamshells can be difficult to remove, further complicating the recycling process.
Another issue with clamshell recycling is the lack of collection and sorting capabilities. According to Alexander, a source from National Geographic, clamshells are often not recycled because they are not collected, and even if they are, most material recovery facilities cannot effectively sort them from other materials. This results in recyclable clamshells ending up in landfills or, worse, in oceans, lakes, and rivers.
To address this issue, some companies, such as Ridwell, offer specialized recycling services for hard-to-recycle plastics, including clamshells. They collect clamshells directly from their members and work with local partners to ensure proper recycling, reducing the risk of contamination. However, this service is currently only available in limited areas.
It is important for consumers to check with their local recycling facilities to determine if they accept clamshell packaging. By advocating for improved recycling solutions and expressing concerns about packaging waste to manufacturers, consumers can play a role in influencing businesses to adopt more sustainable practices and reduce the environmental impact of clamshell packaging.

The food industry accounts for over 60% of clamshell packaging
Clamshell packaging is a popular choice for food items due to its lightweight, durable, and clear structure, which allows consumers to see the product inside. It is also relatively cheap to produce and can be sealed to maintain freshness. The food industry accounts for more than 60% of all clamshell packaging. This is due to the rising demand for convenience foods, urbanization, and the growth of the e-commerce sector.
Clamshell packaging is made from two identical plastic "shells" that fit around the product and hinge on one side, providing a secure enclosure that protects the contents during shipping and handling. It is often used for items like fresh produce, baked goods, and retail products. The clear packaging also enhances product appeal by showcasing its features, making it a preferred choice for retailers looking to enhance product presentation.
While clamshell packaging is technically recyclable, it is often not recycled due to challenges in the collection and sorting process. The recycling process for clamshells can be contaminated by the different bulk density and strong adhesives on labels that are difficult to remove. Additionally, food residues and the cardboard backing on blister packs can also be problematic during the recycling process.
To improve the recyclability of clamshell packaging, local recyclers are adding optical and infrared sorting and processing technology. New developments in advanced recycling technologies will also increase the recycling percentages for clamshells and other plastics. It is important for consumers to check with their local recycling facilities to see if they accept clamshell packaging and to ensure that the packaging is thoroughly cleaned before recycling.
Overall, the food industry's demand for clamshell packaging is expected to continue growing, driven by the need for safe, tamper-proof, and attractive packaging for convenience foods. The market for clamshell packaging is projected to rise, with a focus on sustainable and eco-friendly solutions that meet consumer and regulatory demands.

Clamshells are made from PET plastic, which is highly recyclable
Clamshell packaging is a single-use plastic packaging that is lightweight, durable, and designed to protect its contents. It is commonly used for fresh produce, baked goods, and retail products. Clamshells are made from two identical plastic "shells" that fit around the product and hinge on one side, resembling their namesake.
Clamshells are made from PET (Polyethylene Terephthalate) plastic, which is highly recyclable. PET plastic has the recycling code #1 and is the most commonly recycled plastic globally. However, not all recycling programs accept clamshell packaging, even if it is made from recyclable materials. The bulk density of a PET clamshell may differ from PET bottles, making it challenging to process them together.
When plastic clamshells are processed at material recovery facilities (MRFs), operators and sorting equipment often struggle to differentiate clamshells from other similarly-shaped containers made of different plastics. As a result, the final PET bales may become "contaminated" with non-PET plastics, reducing their market value. Additionally, clamshells often have labels with strong adhesives that are difficult to remove, further complicating the recycling process.
To recycle clamshells, it is important to check with your local recycling facility to see if they accept this type of packaging. Some companies, such as Ridwell, offer specialized recycling services for hard-to-recycle plastics like clamshells. Proper cleaning of clamshells to remove any food residue or other contaminants is also crucial to ensure successful recycling.

Clamshells are hard to recycle due to strong adhesive labels
Clamshell packaging is a popular choice for food items and consumer goods due to its lightweight, durable, and clear structure. It is often used for fresh produce, baked goods, and retail products. While clamshells are technically recyclable, they are not always recycled due to various challenges in the recycling process. One significant issue is the presence of strong adhesive labels on the packaging.
Clamshells, also known as clear plastic containers with a hinged, shell-like structure, are commonly made from PET (Polyethylene Terephthalate) plastic, which is generally recyclable. However, the recycling process for clamshells can be complicated due to the strong adhesive labels often used on these packages. These labels can be difficult to remove, creating a challenge for recycling facilities. The adhesives can leave behind residue or create contamination issues during the recycling process, impacting the quality of the recycled material.
Additionally, the variety and abundance of clamshell packaging designs pose challenges for recycling facilities. The recycling process requires sorting different types of plastics, but clamshells can be difficult to differentiate from other similar containers, especially when they have strong adhesive labels attached. This sorting issue leads to "contamination" in the final PET bales, reducing their market value.
To address the issue of strong adhesive labels on clamshells, recycling facilities and consumers must take extra steps to ensure proper recycling. Consumers can remove labels and wash the clamshells to eliminate food residue or other contaminants before placing them in the recycling bin. However, it is important to check with local recycling facilities, as not all programs accept clamshell packaging, even if it is made from recyclable materials.
Furthermore, the recycling industry is working on technological advancements to improve the recycling process for clamshells and other plastics. Local recyclers are adopting optical and infrared sorting technologies to enhance the accuracy of sorting and processing, which will significantly increase recycling percentages for clamshells and other plastics. While clamshells with strong adhesive labels present a challenge for recycling, a combination of consumer action, industry initiatives, and technological advancements can help improve the recyclability of these packages.

Recycling companies are rapidly adding sorting technology to improve recycling percentages
Clamshell packaging is a single-use plastic that is technically recyclable, but it is not always recycled. It is often used for fresh produce, baked goods, and retail products. The food industry accounts for more than 60% of all clamshell packaging. While clamshells are usually made out of PET plastic, which is highly recyclable, they are not always recycled because they are not always collected. If they are collected, most existing material recovery facilities cannot sort them out from other materials.
Newer laser technologies introduced over the last three years make it possible to remove more impurities from metal and paper products. Sensor improvements now enable optical sorters to pick out fine molecular differences in PET and paper materials to get a cleaner product sort. NIR technology accurately identifies different types of polymers within plastics, enabling precise sorting based on polymer composition. It ensures that only high-quality recyclable materials are selected for further processing while effectively removing non-recyclable contaminants.
Robotic recycling sorting uses artificial intelligence (AI) and robotics to sort plastics, so humans don't have to. Cameras and high-tech computer systems are trained to recognize specific objects and include robotic components over conveyor belts to reach their target. Sensors attached to the arms can detect and interact with cans, glass, plastic containers, and any other recyclable items out of the garbage and place them in their respective bins.
