You can compost a much bigger variety of materials in Subpod than in other worm farm systems! See the full list below:
Most food waste can be composted in Subpod without worry. Fruit and vegetable scraps, eggshells (crush them first), coffee grounds, used tea leaves, spoiled plant-based milks, grains, pastas, breads, nuts (and their shells), seeds, pits, husks and so on. Small amounts of meat, seafood, dairy foods, citrus, onion and garlic may also be added. Subpod can also process spicy herbs, peppers and oils but it’s best to introduce these slowly in small amounts at first, and only once your worms are fully established (after around three months).
PAPER & CARD
Most scrap paper and cardboard can be added to Subpod, as long as it’s not laminated or super glossy. Again, the smaller the pieces, the better. Junk mail, office paper, bills, envelopes (no plastic windows), post-it notes. Paper plates, tissues, egg cartons, paper cupcake liners, baking paper, even card and paper packaging is fine.
Cotton wool balls and pads, tampons, toilet paper cores and even natural latex condoms and gloves can go into Subpod. Old clothing, face washers, napkins, tablecloths and very old towels can be used as long as they are made from natural fibres like cotton, tencel, linen, hemp or wool (no polyester, nylon, acrylic or blends) – just shred them into small pieces first. Washer and dryer lint is okay too, as long as it comes only from clothing made from natural fibres.
WOOD AND BAMBOO
Sawdust (no paint) is great. Toothpicks, disposable wood, bamboo and bioplastic cutlery and crockery can be composted, along with dead matches, bamboo skewers, garden prunings (cut 'em up small), and charcoal from the fireplace – as long as you wash off the ash which is too alkaline for Subpod.
HUMAN AND ANIMAL WASTE
Human hair and nail trimmings, used facial tissue, used cotton bandages and sanitary items can all be composted in Subpod, as long as they are made from 100% natural fibres. Pet hair of all kinds is fine, along with soiled newspaper and hay cage liners and faeces from vegetarian pets and livestock (rabbits, guinea pigs, hamsters, cows and horses). Dog and cat faeces are NOT suitable for Subpod if you’re eating the plants growing around it. But fine if you want to have a separate one for this purpose.
You cannot compost non-organics such as plastic, tin cans, cigarettes, building waste, toxic waste, glass, or any other similar materials in Subpod.
