Worms can process approximately one third of their body weight every day or in organic waste every 2 to 3 days. It is important to work on the combined weight of the worms rather than number of worms, as the amount of worms per kilogram can vary depending on the size and maturity of the worms.

Examples of organic waste that worms can recycle:

• Fruit & vegetable scraps - cooked or raw
• Tea bags and coffee grounds
• Tissues
• Vacuum cleaner dust
• Human and pet hair
• Paper and cardboard
• Natural fibres such as cotton and wool
• Bird seed husks
• Bio-solids
• Animal manure

In large, well-established worm farms, worms can process citrus, onion, garlic, meat, and dairy. However, worms will not consume seeds, plant roots, or people (while they are still alive!) and they won't process anything that can regenerate.
