The worm compost and tea are organic fertilisers for Aquila’s gardens, the veld regeneration project and the tunnels (soil rejuvenation). The earthworms eat cardboard, paper, fruit and vegetables and kitchen scraps. The earthworm farm has been manufactured out of recycled shipping containers. The fertilisers produced on site saves on fossil fuel, along with packaging and transport costs. The excess earthworm tea is sold in ARC’ shop for fundraising purposes. The earthworm tea is also used to supplement nutrients to ARC’s duckweed farm.
