Fancy a Bit of Home Science With Your Bird & Blend Tea Bags?
December 30, 2021
Our tea bags have been compostable since day one!
Our tea bags are 100% plastic-free, 100% natural, and 100% compostable as they are derived from a cornstarch-based material called soilon.
Biodegradable vs. Compostable
Although often used interchangeably there is actually a difference between compostable and biodegradable. In very simple terms, biodegradable means that the material will break down within a reasonable time to a particle size small enough to not be harmful to the environment (e.g. animals can consume it, soil/sea isn't damaged by it).
The time period isn't defined but usually refers to a number of years. Compostable means that the material will break down naturally when placed in a 'compost' environment e.g. microbes, heat, oxygen etc., which is often considered the ultimate goal for planet-friendly packaging as it breaks down within 90 or so days and leaves no trace at all.
♻ There is a BIG COMPOST EXPERIMENT taking place right now...
☕ If you’re one of our lucky customers who has a home composter you can take part in a bit of citizen-science by finding out how quickly our tea bags take to biodegrade.
🐛 This experiment is run by the UCL Plastic Waste Innovation Hub who are working hard to improve composting packaging and waste infrastructure in the UK.
