In today’s environmentally conscious marketplace, food service businesses face increasing pressure to address packaging waste. Plastic clamshell containers, while excellent for food presentation and protection, present unique recycling challenges that many businesses struggle to navigate. Understanding how to implement effective recycling programs1 for these containers can significantly reduce your environmental footprint while potentially creating cost savings and enhancing your brand image.
At Reliancepak, we work with thousands of food service businesses to optimize their packaging solutions, including developing more sustainable approaches to plastic clamshell use and disposal. This guide will walk you through everything you need to know about plastic clamshell recycling programs specifically tailored for food service operations.
Understanding Plastic Clamshell Recyclability
Before implementing any recycling program, it’s essential to understand which plastic clamshell containers can actually be recycled. Not all plastic packaging is created equal when it comes to recyclability.
Common Materials and Their Recycling Potential
The recyclability of plastic clamshell containers depends primarily on the material from which they’re made:
- PET (Polyethylene Terephthalate, #1): Commonly used for clear clamshells, PET has well-established recycling streams in most regions. These containers typically feature excellent clarity and are frequently used for salads, sandwiches, and bakery items.
- PP (Polypropylene, #5): Often used for hot food applications, PP clamshells have moderate recycling acceptance that varies by region. These containers offer good heat resistance and are common for prepared hot meals and microwave-ready foods.
- PS (Polystyrene, #6): Used in both rigid and foam formats, PS has limited recycling acceptance in most regions. While inexpensive, these containers face increasing restrictions in many jurisdictions.
- PLA (Polylactic Acid): These plant-based containers require commercial composting facilities and cannot be recycled in conventional plastic streams. They’re often marketed as “compostable” but require specific disposal conditions.
Recycling Symbols Demystified
Food service managers should familiarize themselves with the standard recycling symbols found on plastic packaging:
- The Resin Identification Code (numbers 1-7 inside the chasing arrows triangle) identifies the plastic type but doesn’t guarantee recyclability.
- How2Recycle labels provide more specific guidance on packaging recyclability based on current infrastructure.
- Compostable certification symbols indicate the packaging requires commercial composting facilities.
| Material | Resin Code | Typical Recyclability | Best Applications | Common Challenges |
|---|---|---|---|---|
| PET | #1 | High in most regions | Cold foods, display items | Food contamination |
| PP | #5 | Moderate, varies by region | Hot foods, microwavable items | Limited collection in some areas |
| PS | #6 | Limited, declining | Inexpensive applications | Increasingly restricted |
| PLA | #7 (with PLA marking) | Not recyclable (compostable only) | “Green” marketing applications | Requires special processing |

Common Recycling Misconceptions
Many food service businesses operate under misconceptions about plastic clamshell recycling:
- Misconception: All plastic with a recycling symbol can be recycled anywhere.
Reality: Local recycling capabilities vary significantly; the symbol only identifies the resin type. - Misconception: Compostable plastics can be recycled with regular plastics.
Reality: Compostable plastics contaminate conventional plastic recycling streams. - Misconception: Lightly soiled containers are recyclable as-is.
Reality: Food contamination significantly impacts recyclability; containers generally need rinsing. - Misconception: Material reduction is less important than recyclability.
Reality: Reducing material use (thinner containers, right-sizing) often yields greater environmental benefits than recycling alone.
Current Challenges in Clamshell Recycling
Food service businesses face several specific challenges when recycling plastic clamshell containers.
Food Contamination Issues
Food residue presents the most significant barrier to successful recycling:
- Even small amounts of food waste can contaminate entire batches of recyclable materials
- Oils and fats are particularly problematic as they interfere with recycling processes
- Cleaning containers requires water and labor, creating operational challenges
- Customer-disposed containers typically have higher contamination rates than back-of-house waste
Collection and Sorting Infrastructure Limitations
The physical design of clamshells creates unique recycling challenges:
- Their three-dimensional shape makes them difficult for automated sorting equipment to process
- Clear PET clamshells are often mistakenly sorted with PET bottles, causing processing problems
- Many material recovery facilities (MRFs) lack the specific equipment needed to properly sort clamshells
- Collection systems may not distinguish between different plastic types, leading to contamination
Economic Factors Affecting Recycling Programs
Market realities impact the viability of recycling programs:
- Fluctuating recycled material markets affect program economics
- Virgin plastic prices often remain lower than recycled content
- Transportation costs for low-density materials like clamshells can be prohibitive
- Processing costs for food-contaminated packaging are higher than for clean materials
Regional Variations in Recycling Capabilities
Recycling infrastructure varies dramatically by location:
- Urban areas typically offer more recycling options than rural locations
- Some municipalities have specific programs for commercial food packaging
- Certain regions have banned specific packaging materials entirely
- International variations create challenges for businesses operating across borders
Implementing an Effective In-House Recycling Program
Despite these challenges, food service businesses can implement successful plastic clamshell recycling programs with proper planning and execution.
