Composting with Worms
Everything you need to know about vermicomposting
Organic materials make up approximately two-thirds of the waste stream. While much of this is paper which can be used more efficiently or recycled, a large portion is material like food waste for which few beneficial options outside of composting exist. Fortunately, nature has provided one option that has been receiving increasing attention--vermicomposting.
So what, you may ask, is vermicomposting and how does it work?
Well, "vermi" is the Latin word for worm, and worms like to feed on slowly decomposing organic materials (e.g., vegetable scraps). The "end" product, called castings, is full of beneficial microbes and nutrients, and makes a great plant fertilizer. So, vermicomposting is the practice of using worms to make compost simply by feeding them your food waste.
The reason vermicomposting is becoming popular is because worms are very efficient eating machines. They eat over half their body weight in organic matter per day!
