A little while ago I wrote a post about Red Rose Tea. I was suspicious of the fact that their tea bags don’t degrade in my compost, and I e-mailed them about it. Well, the good news is that they wrote me back. Here’s what they said:
Thank you for contacting Red Rose.
The new Red Rose tea bag material is poly lactic acid, or PLA. The new tea bag is an organic polymer made from plants sources. The tea bags are composed of 100% renewable plant materials. The new Red Rose tea bag material is tested by independent laboratories and has been shown to be completely safe.
Sealing Red Rose like our previous Red Rose tea bags and other single chambered (or pillow) tea bags on the market, Red Rose uses a heat sealable material. However, unlike most other single chambered tea bags in the market Red Rose is now 100% compostable and made from 100% plant material.
We truly appreciate your loyalty to our brand and products. Should you have any questions in the future, please do not hesitate to contact us again.

I like Red Rose Tea, and I like getting polite letters like this. Unfortunately, I am also cynical, and I still haven’t forgotten what they did to those chimpanzees all those years ago. So I did some research on poly lactic acid.
I found out that Poly lactic acid (PLA) is a biodegradable polymer made out of renewable resources like sugar, corn starch or cassava. It’s used for 3D printing, short term packaging, and even for medical uses (implants, sutures, drug capsules), among other things, and is classed as an environmentally friendly material. It will break down, but takes a long time to degrade, which is why it haunts my compost.
So there you have it: not toxic or harmful to the environment. I still like the old bags better, because they made better compost, but I’m back to drinking Red Rose.
But just to be clear: no more chimp tea parties, OK?
