Rat-proof Composting

Background

Standard advice for composting is to restrict yourself to prunings and vegetable peelings, avoiding cooked food and especially meat and dairy.
Since meat, dairy and any cooked foods compost really well, the reason for this advice is largely to reduce the bin’s attractiveness to rats.

Solutions: Retro-fit Steel Collars and New Slatted Bins

We have trialled two rat-proof composting approaches so that a wider range of materials can be home composted.
The first is a steel collar which goes around the base of a standard ‘Dalek’ style compost bin. The second is a new slatted bin made of tough uPVC.
In each case the bin must be placed on hard standing (concrete, slabs, bricks, blocks, paviours or Tarmac) to prevent burrowing by rats.
We wished to determine if our two designs were truly rat-proof thereby enabling people to comfortably put a wider range of material into their bins and reduce waste.

The Results

With over 20 installations – some of which have been in place for nearly two years – the trials have been a success; none of the bins have been invaded by rats.
If you’re interested in taking part let us know!

Cost

Both the steel collars and the new slatted bins are manufactured by commercial companies.
Stock is purchased from these companies and subsequently supplied – at cost – to project participants via Transition.

Collars: We currently have stock. Prices, based on existing supplier purchases, are £49 for each collar.

Slatted Bins: We currently have no stock. Furthermore, we have been informed (21st Feb 2022) by the manufacturer – which may be the only organisation making the flat piling that we use for the bin’s construction – that they have stopped manufacture of that component.  We are exploring other options and other broadly similar designs. There is currently no ETA.

How to Participate

The project is no longer in trial mode.
We have proven solutions if you have an existing rat problem. Similarly, if you wish to compost a broader range of materials without subsequently suffering from rats, our solutions will support that change.
We have found that it is best if we make a quick site visit before any purchase and installation. However, we now have installations in Winchester, Alresford, Oxford and Hastings where no site visits were made beforehand. We can discuss delivery costs as appropriate.
