The best straw recycling programs are those that accept a broad range of materials—including paper, polypropylene (PP), and PLA—while providing clear collection pathways and partnering with specialized processors. Unfortunately, many curbside recycling systems are not equipped to handle straws of any kind due to their small size and contamination risk. Understanding how straw recycling programs actually work is the first step toward reducing straw waste.
How Do Straw Recycling Programs Work?
Straw recycling programs vary widely by region and material type. Most programs rely on consumer sorting: paper straws go into paper/cardboard streams, polypropylene straws into #5 plastic streams, and PLA straws into industrial compost (not recycling). However, because straws are small and lightweight, they often fall through sorting screens at material recovery facilities, ending up as residue. Consequently, even well-intentioned recycling programs for straws may have low capture rates. For a deeper look at PLA’s challenges, see our article on PLA straw environmental truth.
Which Materials Can Be Recycled Through Straw Recycling Programs?
The recyclability of a straw depends entirely on its material and the local recycling infrastructure. Here’s a quick breakdown:
- Paper straws: Recyclable if clean and dry, but many contain PFAS coatings that complicate processing. Learn more about PFAS in paper straws.
- Polypropylene (PP) straws: Technically recyclable (#5 plastic), but only if collected in large enough volumes to be economical.
- PLA (bioplastic) straws: Not recyclable in standard plastic streams; they require industrial composting facilities, which are rare. Only about 9% of all plastic waste is recycled globally, and PLA straws contribute to that low rate when mistakenly placed in recycling bins.
- Grass straws: Compostable at home or industrial facilities, but rarely accepted in curbside programs.
Why Most ‘Compostable’ Straws Don’t Fit Into Recycling Streams
Many consumers assume that compostable straws (e.g., PLA) can be tossed into recycling bins—this is a common misconception. PLA straws look like plastic but behave differently in recycling systems. They contaminate polypropylene recycling batches and degrade the quality of recycled plastic. Furthermore, most municipal composters refuse to accept PLA due to long degradation times and lack of infrastructure. As a result, these straws often end up in landfills. To explore safer materials, see our guide on PFAS-free straw options.
How Businesses Can Implement Effective Straw Recycling Programs
Businesses that want to support straw recycling programs should take a proactive approach. Here’s a practical plan:
- Audit your straw material—switch to a material that has a viable recycling or composting path in your area.
- Label clearly—place signs at disposal stations indicating which bin (or collection box) straws belong in.
- Partner with a specialized recycler—companies like TerraCycle offer dedicated straw recycling boxes for polypropylene straws.
- Educate customers—use social media or in-store posters to explain proper disposal.

FAQ
Q: Are paper straws recyclable?
A: Yes, paper straws can be recycled if they are clean and your local recycling program accepts mixed paper. However, many paper straws contain PFAS coatings that contaminate the recycling process, so check with your facility first.
Q: Can PLA straws be recycled through straw recycling programs?
A: No, PLA straws are not recyclable through standard curbside programs. They require industrial composting facilities, which are not available in most communities. Always dispose of PLA straws in compost bins that accept bioplastics, or send them to specialized composters.
Q: How can I find a local straw recycling program?
A: Start by contacting your municipal waste management office to ask if they accept straws. For polypropylene straws, look for dedicated programs like those offered by TerraCycle or similar specialized recyclers. You can also partner with a local composting facility that accepts certified compostable straws.
Conclusion
Straw recycling programs face significant challenges due to material diversity and infrastructure gaps. The most effective approach is to choose straws that are either widely recyclable (like clean paper) or certified compostable and supported by local facilities. By understanding what actually happens to used straws, consumers and businesses can make smarter choices.
