In small amounts can be composted providing it consists of natural fibre from wool, cotton or hemp (not synthetics or blends).
Fat.
OK to put in compost or worm farm in small quantities. Fats, oils, roast drippings, butter, ghee, cream and cheese will tend to coat particles in the compost and cut off their supply of air. If you are disposing of table scrapings then a little fat is fine. Larger quantities should be buried in the garden. Choose a site where you are not likely to be digging regularly and bury about 30cm (1 ft) deep. Do not under any circumstances dispose of fats or oils down the sink.
Feathers.
For nitrogen. OK to shred and put in a cold composting heap.
Fish bones and prawn shells.
OK to put in a hot or cold heap or a wormery in small quantities. See meat and bones.
Flowers.
For nitrogen. Suitable for hot or cold compost heaps. Good for prettying up the wormery too.
Food wastes.
Suitability varies. Meat products, fish, eggs, dairy foods, butter and oils are OK in small quantities but you should be careful when adding large amounts. Try leftovers in a worm farm and see if your worms go for them. For vegetable matter like peelings and other fresh vegetable and fruit wastes, a wormery or a hot or cold compost heap are all OK. If you compost in a backyard heap be careful to add enough carbon to balance the high nitrogen and water content of the food scraps or else things could get pretty slimy and smelly.
G
Garlic.
Not suitable for a wormery. OK in a hot or cold compost heap.
Carbon. Best put through mulch maker first. Suitable in a hot or cold heap. Leave plenty of time to break down.
Grass clippings (fresh).
For nitrogen. Great in a hot or cold heap. Composed of fine particles that compost down quickly. Note: a lawn that is well watered and well fed will have higher nitrogen than lawn which is dry and straw coloured. If you mow your grass regularly it is suggested that you leave the clippings on the lawn because this returns valuable nutrients to the grass and acts as a mulch. However, if you value compost on your garden more, then make compost!
