Can teabags be composted?
always recommend that gardeners put their used tea bags in their
home compost bins but some tea bags leave a plastic web behind once
the tea leaves have rotted away.
Organic teas are usually contained in unbleached paper bags
and should rot down completely in a few months.
But many tea bags contain a plastic called polypropylene that is not
biodegradable and it is this that leaves the residue. Which?
Gardening contacted a number of tea companies to find out what
proportion of their tea bags are fully compostable. These are their
Twinings have 0% polypropylene
Sainsburys Taste the Difference English Breakfast tea (Fairtrade)
Morrisons M English Breakfast tea has 10%
PG Tips tea bags have 20%
Yorkshire tea bags have 25%
So the more polypropylene the more bits of plasticy stuff you are
going to find in your compost.
However it is always worth putting tea bags in your home compost bin
as the leaves and paper parts add good structure and some nutrients.
If you wish to use your compost for seed sowing or potting on, you
will need to sieve out the bits of twigs and slow to rot stuff
