Teapigs Tea Temples
The "tea temple" pyramid is Soilon (PLA) mesh - a bioplastic marketed as plastic-free, complete with a Plastic-Free Trust Mark.
The verdict: Mostly plastic
Teapigs' "tea temple" is made of Soilon, a PLA (cornstarch-derived) mesh, so the bag itself is bioplastic - a synthetic polymer steeped in hot water. To its credit Teapigs is upfront that the temples are NOT home-compostable and need industrial/council food-waste composting. But PLA is still a plastic that sheds micro- and nanoplastics when brewed, so a "plastic-free" claim - and the Plastic-Free Trust Mark the brand carries - is the greenwashing case study this category exists to flag, not a clean bill of health.

What it's made of
| Part | Material | Food contact |
|---|---|---|

Teapigs sells whole-leaf tea in a roomy pyramid "temple" that shows off the ingredients. The brand leans hard on sustainability messaging, including a Plastic-Free Trust Mark on packaging.
Pros
- Whole-leaf tea with room to expand, and honest that the temples are not home-compostable
- PLA is plant-derived and industrially compostable, unlike a nylon/PET pyramid
Cons
- The temple is PLA - a bioplastic, so it is not plastic-free despite the "plastic-free" marketing and Trust Mark
- PLA only breaks down in an industrial composter, and still sheds micro/nanoplastics when steeped
