In my experience, there are very few types of waste that cannot be added to a vermicompost. I'd say all kinds of typical fruit and veg waste are suitable, as are peels, ends, and odd bits like that. You can also add coffee grounds, teabags, various types of grains and wheat such as bread, eggshells (provided they are rinses properly) and green waste too. You can also add plenty of liquids too, such as dairy and beer. The only thing that should be avoided are meats, as these could purify and could a dangerous environment.
This being said, the persistent addition of green waste should be avoided. This will have a detrimental effect on thee effectiveness your vermicompost. For large scale green waste management, or for example your food ahas purified, it's always better to remove it from your compost let someone else take care of it. As a side note, always take into account what happens to the waste you put out for collection. For reference, only get rid of surplus green waste if a company meets this criteria:
