NIAGARA, Wis. — The Niagara Public Library will present a program on worm bin composting (or vermicomposting) at 1 p.m. Tuesday, June 13.

Kitchen scraps can be composted using unlikely little eating machines — worms. Worms can eat nearly their body weight in food scraps every day, which become compost as they pass through the worm’s body.

The end result is called castings, an odor-free compost product for use as mulch, soil amendment, or topsoil additive. This process allows some kitchen waste to be diverted from landfills and used in yards and gardens.

“During the program, we’ll learn a little bit about our new worms, then create a worm compost bin. The bin will be kept at the library and we’ll have a weekly ‘worm feeding’ after our Tuesday afternoon programs,” said Rebecca Livick, librarian. “If you’d like to contribute to the worm food, keep in mind that the worms will like to eat many fruit and veggie scraps, coffee grounds, tea bags, egg shells and shredded newspaper. They should not have citrus fruits, onions, garlic, potato peels, dairy products, meat or fish.”

Participants can keep a Ziploc bag of “worm food” in the freezer to bring to the library on feeding day.
