The first two are compostible. Bones,
Ground up heat treated bone is commonly applied to gardens.

other stuff of animal or fowl origin cannot be composted.
I once watched a TV program where the commercial company claimed that
could almost compost anything organic from the food industry. The
programmed showed their operation where one heap was the waste from
chicken processing including feathers. They had gigantic heaps on the
runway of a disused airport and the heaps were turned and mixed with the
help of bulldozers.
In council collections the food waste (including all the things you
believe cannot be composted) does not go to landfill.
My council states:
Quote:
Once the food waste is collected from the blue food waste bins it is
bulked for transportation on to its reprocessor.
In vessel composting (IVC) and anaerobic digestion (AD) are two
technologies available for reprocessing food waste into a valuable
end-product. Due to the controlled nature of these processes all types
of food waste can be safely reprocessed - from fruit and vegetables to
bakery, dairy and meat products - to develop a product that can be used
as an agricultural bio fertiliser and soil improver. AD also produces
biogas which can be used to produce renewable energy.

This is
why pig farmers no longer collect 'swill' from schools. The possibility
of another foot-and-mouth outbreak is ominous. This sort of food
waste must go to landfill.
Unable to compost is not the reason. I believe that this type of waste
cannot be guaranteed to have been heat treated to the required high
temperatures and it's not economic to do this on a small scale.
Unless you grow your own carrots (which means you have space for a
compost heap or bin anyway), where are these 'greens of carrots' coming
from ? You only need to chop off the top 1/4 inch. How can you
end up with 240 litres a week ?.
Some people don't buy their carrots pre-packed in a supermarket and even
then some "organic" branded carrots sold in supermarkets often are sold
with the leaves.
I was lead to believe that many root vegetables had a longer
shelf/storage life with the greenery removed as once picked the dying
leaves suck moisture from the root.
