The carryoncomposting page on tea bags has been ubdated 

The loose tea brewed in a teapot or tea ball can be easily composted. Tea leaves are a good source of Nitrogen (Greens) organic material for the compost bin which will be moistened during the brewing process encouraging decomposition. The tea ball or strainer can be emptied directly into the kitchen caddy while loose leaves can be scooped from the pot into the caddy by hand, once cool.

Teabags are usually listed as compostable items but in recent years more and more composters have complained that the bags do not actually decompose when composted. In 2010 a report by Which? Gardening, found that six out of the seven largest tea bag manufacturers did not make fully compostable bags. This is because at the bags include a non-biodegradable plastic (polypropylene) so that they can be more easily heat-sealed during manufacture.  The bags may be described as “70% or 80%” compostable which includes the tea leaves and paper element of the bag but not the plastic.

Although each individual teabag is small they account for about 150 tonnes of polypropylene going to landfill, AD or composting a year in the UK alone. This is equivalent to about 165 million teabags a day. Many of these are composted in food waste.

The COOP announced in January 2018 that it was in the final stages of developing a plastic free biodegradable teabag for its own brand Fairtrade 99 teabags. The Coop which sells 367 million teabags a year hopes to have the new bags in their shops later this year.


Some teabags are already plastic free making the bags ideal for composting. This is list was published in April 2018:

  • Teapigs
  • Pukka Tea
  • Jacksons of Piccadilly
  • Twinings Pyramid tea bags
  • PG Tips pyramid teabags
  • Tetley’s catering range
  • Clipper string and tag teabags


Mike Armitage a gardener from Wrexham started a petition to get manufacturers to remove all plastic from tea bags after finding residue from teabags in his garden compost. Details of the 38 Degrees petition can be found at ( The petition succeeded in persuading the UK's largest tea bag manufacturer Unilever/PG Tips to announce that they will remove plastics from their teabags.

But the other leading UK teabag manufacturers are still using plastics in their teabags, although the following are expected to become plastic-free during 2018

  • Clipper pillow teabags (the string and tag Clipper teabags are already plastic free)
  • PG Tips standard teabags
    • Tetley teabags (Tetley string & tag teabags which are used mostly in their catering range of individually wrapped tea bags are plastic free).   
    • Co-Op 99 teabags

Compostable teabags made of a corn starch (SOILON) are sold by the Brew Tea Company and Teapigs. These will hot compost in about 6-8 weeks around 12 months in a cold composting system.

Pukka Tea teabags are sewn by machine with cotton thread, not heat sealed, and do not contain plastic. The teabag paper is made of a blend of natural abaca (a type of banana) and plant cellulose fibres.

Fruit, herbal and green tea ranges may already use a compostable tea bag material which can be put straight in the compost bin.

 Composting Tea bags

Before the current concerns about plastic in teabags the advice when home composting was to use loose leaf tea or if using teabags that did not decomposing during the composting process i.e.  non-compostable bags:

  • tear open the bags before putting them in the bin
  • or sieve or pick them out after composting.

I have seen advice recently suggesting that to avoid the risk of the plastic entering the home compost, and eventually the soil, the bag should be emptied by cutting the top off the bag and tipping the tea residue into the kitchen caddy allowing it to be treated as loose tea. Unfortunately, if the empty bag is put into the household (landfill) rubbish bin the plastic will still enter the soil.

The Compost Safari session at Coalville Library this morning was well attended with several families registering in the last few days. As with the sessions at other libraries, earlier in the holiday, the children where given compost from wormeries being used to compost uncooked kitchen waste to search for worms, worm eggs and other compost creatures.
This was the last of the Easter holiday sessions but I am able to offer sessions for schools during the term. For further infomation  email Details of other school and library sessions can be found at Compost classes (1) with more infomation on the Safari sessions at Compost Safari

The Compost Safari at Hinckley Library today (4th April) was attended by 28 children and parents. The final Safari in this school holiday is at Coalville Library, High Street, Coalville, Leicestershire, LE67 3EA  on 6th April at 10:30  Spaces must be pre-booked

 Tel 01530 832019. Email

The Compost Safari encourages children to search for worms, worm eggs and small creatures e.g. slugs, woodlice, mites, that live in your compost bin or wormery turning plant and food waste into compost. This event is for children aged 4-11 years. Details of the current LCC special offer on compost bins will be available at the session.

Compost Top Dressing 

Top dressing a lawn with compost can improve the soil structure and provide  nutrients. It will also improve drainage and by adding organic matter to the lawn. It can also be used to fill holes and depressions

A top dressing of compost is often applied to the lawn in the autumn. However, the value of more frequent but lighter applications of compost as a top dressing is now being recognised and easter is a good time to start.   If adopting this routine of treatment, the first treatment is best applied early in spring when the lawn will be receiving less footfall, reducing the likelihood of compost being carried indoors. It and can be repeated every month where the lawn is used regularly.  It is best to sieve or break up the compost as smaller particles can drop between the blades of grass and become incorporated into the soil easily.  It is best applied it dry.

Mow the lawn's grass to 1 inch tall. That height helps compost reach the soil between grass blades. Rake the lawn with a metal rake to collect dead grass, leaves and other lawn debris  

Compost can be used to top dress the lawn in the autumn but it can also be used in the spring to start the season but do it early so that the lawn will be looking good when you want to use it. The use of compost to make liquid feed is given on a separate page Liquid Feed

A full, and free,  Compost Creatures session at Oadby library today. this is one of the sessions for younger children allowing them to hunt through compost from two of the wormeries looking for composting worms, potworms  woodlice and other winter visitors to the wormery. Very few slugs or snails yet this year. Tomorrow it is a repeat of the session at Glenfield library.
