A Wheelie bin compost bin made by D Robbins with a hatch simply secured by rope rather than hinges and a bolt
In the past it was quite common for councils in the UK to provide a free green waste collection service to householders. This kerbside collection of garden waste used wheelie bins provided by the council. As a result of the cuts in funding many
councils have now introduced a charge, typically between £20 and £50, for this collection. While the take up of this paid for collection is normally sufficient to provide the council with an additional income source a significant number of householders
have opted not to participate in the new service and now as the council if the council does not intend to collect the non redundant wheelie bin taking up space in the garden. These can easily be converted into compost bins if the council will not
collect them or pay you rent for the space they occupy.
Before starting the conversion it will be necessary to decide whether you will want to harvest the leachate (liquid produced during the decomposition of the waste) or whether the leachate is to
be allowed to drain away.
The simplest conversion where the leachate is allowed to drain away will require drainage holes to be drilled in the bottom of the bin. This will also allow worms to enter the bin from the soil.
I would recommend that a three or four rows of holes be drilled just below the lid to provide additional ventilation. Additional rows can also be drilled halfway down the bin.
To make the hatch, for the removal of the finished compost using a garden
spade, neatly cut out a rectangular section from the front of the bin near the base. Make it as large as possible using the flat surface between the raised corners. Ideally the lowest cut should be level with the base inside the bin. The piece of plastic
removed can be refitted with by hinges at the top and with a bolt at the bottom to make a hinged hatch. A small self adhesive hook can be stuck onto the bin above the fitted hatch so that it can be tied open while compost is being removed.
the leachate is to be harvested add a tape near the base fitted to a plastic tube so that the liquid can be drained into a container and diluted for use as a liquid feed. In this case the bin is best mounted on a couple of breeze blocks to raise the height
so as to make drainage easier.
