Many thanks for your recent enquiry regarding the composition of the Aerobin
We've never been asked the question of material used in manufacture before so I had to fire off a message to the company to find out.
Here's what they said; "The Aerobin is not manufactured from Recycled Polymer - its
100% Virgin Polymer. If it was in fact manufactured from recycled polymer it would
contain significantly more polymer than it actual does."
I hope this information helps you and I know of a few keen composters who like to wrap their chosen compost vessels in greenhouse insulation bubble wrap material at this time of year, just to keep temperatures a couple of degrees higher and help the essential life inside the heap to tick over; maybe this is something you'd like to consider as well ?
If there's anything else you'd like to know please don't hesitate to contact me and the best of luck with your composting activities.
