Empty 5L HDPE Plastic containers with built in handle.
Often taken off our hands for use on allotments as water carriers or repurposed to become plant cloches.
Some have sliced the container vertically, leaving the bottom in tacked, sealed the sharp edges with tape and use the screw lid to clamp shit making a child’s toy first aid box, etc…
We have come a long way lobbying companies and our suppliers to operate in a circular (refill) economy. Many successes, most recently, Bio D now return and refill their new design 20L detergent containers and have extended the service to Suma for their bathroom supplies.
Faith in Nature we are sure will follow suit, but for now, we save all containers that pass through our hands and bide our time until another use becomes available.
