What is PLA/CPLA, how is it different from normal plastic, and where does it fit?
Plastic, but from plants
PLA (and its heat-stable cousin CPLA) is made from plants like corn — not petroleum. It looks and behaves like conventional plastic for many uses: clear, mouldable, sturdy. The crucial difference is what it's made from and how it ends.
How it's different from regular plastic
Conventional plastic is fossil-based and persists for centuries, shedding microplastics. CPLA is plant-based and certified compostable — in a commercial composter it returns to soil, leaving no permanent polymer behind.
Made from plants, not petroleum.
No BPA, no fossil feedstock.
Certified compostable (commercial facility).
No permanent microplastics.
The honest caveat
CPLA needs a commercial composter, not a backyard bin — so check local access. It's a strong bridge material: a plant-based stand-in for plastic in formats like cutlery and cold cups while fully home-compostable options mature.
Where conventional plastic still fits
For a few formats we still offer recyclable PP and PET because they're affordable and perform — chosen BPA-free and recyclable, and flagged honestly. Our roadmap moves these toward plant-based as performance and price allow.
Key takeaways
PLA/CPLA is plant-based plastic, not petroleum.
Certified compostable — but commercial facilities only.
A bridge material while home-compostable options mature.
