The Urban Worm: Loading...

Welcome to The Urban Worm

Nurturing people, plants and the planet is at the heart of what we do. We want to help build sustainable societies and cities that thrive in the face of adversity, and we believe the humble composting earthworm is a key player in tackling food waste and sustainable food production.

In the UK we send over 25 million tonnes of food waste to landfill every year, costing the economy (approximately 2.3 billion) and the earth. Food waste emits the powerful green house gases GHG Methane CH4 and Nitrous Oxide N2O that are 21 and 310 times stronger than Carbon Dioxide CO2, escalating the threat of climate change and undermining food security.

At The Urban Worm we see this food waste as a valuable resource waiting to be turned in to 'Black Gold', other wise known as worm castings or worm poop, the finest organic fertiliser known to man. Worm castings contain an abundance of minerals and nutrients essential for healthy plant growth and disease suppression, helping us grow our own without the use of costly synthetic fertilisers.

We have lovingly developed components to transform wheelie bins into wormeries. It could never be easier to make your own 'Black Gold', providing you with a steady supply of the finest liquid fertiliser and compost.

Featured testimonial

 I absolutely love the work Anna and The Urban Worm are doing. I specialise in educational edible gardens and the wormeries which she supplies me with are fundamental to the success of the garden. The children are amazed by the wormeries, not only by seeing the worms but also the deeper concept. These wheelie bin wormeries really do work on a practical level, and they really do inspire on an emotional level. Well done Anna- keep the good work up!
