What is the HOTBIN made of?

Wednesday, 13 February 2013  |  HOTBIN Composting

The HOTBIN is made from ARPRO® Expanded Polypropylene also known as EPP.

This is a specialist plastic that is very durable. ARPRO® EPP offers high impact strength (used extensively in car bumpers as shock absorber)and tremendous insulation properties too.

The HOTBIN is definitely NOT made from expanded polystyrene (EPS). EPS is far too brittle to survive the rough and tumble life of an outdoor compost bin.

It 'looks' a little like polystyrene because it is made in a similar manner, ie the raw plastic is made into 'beads' (each one containing air) and then the beads are moulded under pressure into the HOTBIN shape.

Polypropylene is the same plastic used to make garden chairs and tables, the key difference is these are made via injection moulding and are solid plastic, where the HOTBIN is expanded beads so the unit is about 96% air.

We offer a 3-year manufacturer’s guarantee, and subject to proper use, we expect it to last 10-20 years. We advise you take care with sharp implements like garden forks and sharp knives as these can puncture or cut into the walls.
