Composting Bins

Does anyone know where I can buy a composting bin in Miri?
Someone told me they saw one but can’t remember where? They are usually green, larger than a normal rubbish bin and have a lid but no bottom.

If you compost it really reduces the amount of waste you produce and it creates great soil to use for your plants.

See here for instructions on making your own composting bin - I may have to do this but I would rather buy a purpose built one if I can.

By the way you should also recycle at the Red Crescent - they do a fantastic job.
