We recommend brewing this mint tea for 5 minutes at approximately 100°C
The tea bags are made from a biodegradable corn starch which can be put in with the food waste. They are heat-sealed (which means no glue is used) and the paper tag and strings are all biodegradable, too. These are not suitable for garden composting.
The tea bags are placed in a clear wrap, made from Natureflex, which is biodegradable and can be put in with food waste. This clear wrap is also garden compostable.
This is placed into a food-grade, lined tube and the idea is that you use it to store the tea once it's opened.
