Plastic bins 2. Cube shaped/staight sided composters

Cube shaped, staight side or box bins fit well in corners of a modern garden and many have larger hatches than the conical bins. This is a bit of a catch all group as some have rounded corners but in most cases the base and top are the same size.  The shape of this type of bin makes it easy to insulated using loft lagging, bubble wrap or even bales of straw to carry on composting during the cooler months.

Tekplas Compost Bin 500 Litre capacity.

Available from     Price March 2014    £66  Compost Bin, AddOn £51.60

 This UK manufactured garden compost bin is made in upvc but looks like a conventional New Zealand box providing a modern twist on the conventional bin that has been used  by generations of gardeners. It is supplied with four galvanised steel ground stakes which fit inside the corner posts and brace bars  giving  stability to the finished bin. We have found this to be a bit of a problem where the brace bars move in the ground. The green plastic tongue and grooved twin wall boards provides good insulation  which I feel  will more than compensate for the fact that the bin is smaller than the conventional 1m cube recommended for wooden bins having 80cm sides. The plastic boards can be removed in the same way as the wooden boards of a traditional bin. “Add ons” are available so that bins can be linked  together to make a 2 or 3 bin system. The bin could also be used as a Maturation bin for compost produced using one of the smaller  tumbler composters.
