Composting At Home

Reduce your waste by a third

Compost bin full of vegetable peelings and worms being forked-over.Vegetable peelings, prunings, paper and a list of other things from your kitchen and garden will decompose easily and naturally in a compost bin, leaving you less waste to bag up and put out for collection and further processing.

About a third of your waste can be composted at home, saving energy and resources and benefiting your garden and your pocket.

In your compost bin this biodegradable waste can be broken down into convenient, free compost very easily by useful insects and micro-organisms – but if this waste reaches a landfill site, mixed with and buried under other rubbish, little air would be available to support the micro-organisms that could have flourished in your compost bin.

Where can I get a compost bin?

Merthyr Council offers subsidised compost bins at a cost of £15 including delivery.  For further info please contact us

Man filling home made compost bin with grass cuttings.How do I start?

Put a compost bin anywhere that is convenient, perhaps easily accessible from the kitchen, and start filling it.

Tips – Location:

A compost heap is best sited on soil (worms and creepy crawlies will find it easily) but will work on concrete, providing there is some drainage.

Keep a handy container in the kitchen for your kitchen waste, to reduce the amount of trips you take to the bin.


What should I put into my bin?

Your bin needs a mix of things that rot at different speeds – no sorting required.

Fast Rotters Slow Rotters What Shouldn’t I Compost
Fruit waste Woody prunings Meat/fish/bones
Raw vegetable peelings Plant stems Dairy products
Flowers Twigs Cooked/ processed food
Weeds Autumn leaves Coal ash
Hedge clippings Crumpled cardboard Cat/dog (carnoviare) litter/poo
Grass clippings (not too many at once) Egg boxes Root of perennial weeds (dandelions, ground elder, bindweed, couch, docks)
Teabags and coffee grounds Egg shells  
  Wood shavings  
  Animal (herbivore) manure e.g. hamster/guinea pig  
  Loo/kitchen roll centres  

Tips – the mix:

Fast rotters rot quickly, and can become compacted/wet so mixing them with slow rotters should prevent the compost becoming slimy and smelly. Slow rotters tend to be dryer so compost more slowly. They give the compost texture and create air pockets throughout the heap. Your home compost bin should ideally have a 50:50 proportion of slow rotters and fast rotters.
