A worm compost bin is a compact, eco-friendly composting system that uses beneficial worms (typically red wigglers) to break down kitchen scraps and organic waste into nutrient-rich compost and liquid “worm tea.” Designed with stacked trays or layers and ventilation holes, the bin creates an ideal environment for the worms to thrive while keeping odors contained and moisture balanced. You simply add fruit and vegetable scraps, coffee grounds, and other compostable materials; the worms consume and transform them into dark, crumbly castings that make excellent fertilizer for gardens and houseplants. Easy to maintain and suitable for indoor or outdoor use, a worm compost bin offers a clean, sustainable way to recycle food waste and enrich your soil naturally.
