I would never use particle board for a compost bin! You're putting poison into your soil and into your plants/food.
You don't necessarily want to add worms to an established compost bin. Worm composting is only for organic food scraps. If you want to compost other stuff, you still need a regular bin. The advantage of the worms is that it is a faster process. The worms eat the scraps and their waste is what you use in the garden. This process also creates a liquid that can be collected and used as fertilizer.
Because of climate/weather changes, it's probably best to have a worm bin indoors.
How do you figure particle board is poisoning the compost/soil? Got any more info on that? Pressboard was all we had available at the time, and it's not that much different (in terms of materials used) than plywood, which is what my in-laws old bin was made out of, and it served them fine for many years while my husband was growing up.
Aside from pet hair and egg cartons, most of our compost is food scraps (strawberry tops, potato skins, banana peels, etc). That and flower cuttings go in there as well, but it's still organic refuse (which is the only stuff that composts anyways, so I'm not sure what you mean about composting other stuff...).
How do you put a worm bin indoors? I heard of a guy who's got one in his garage, but we pull our vehicles in, so we don't have room for that.
