Scotty’s Hotbox Maturation Box

Scotty's Hotbox compost maturation boxScotty’s HotBox is a brainchild of Nicky Scott, developed in line with Green Machine Solutions at the Worm Research Centre.

Nicky was fed up with not being able to find a large enough (one metre cube) secure composter with a sturdy base and lid, which would hold a sufficient mass of material to keep warm even through the winter. When composting food waste, it is important to keep the system active for 12 months of the year, but Nicky couldn’t find a composter substantial enough. Therefore, the HotBox was developed!

Scotty’s Hot Box costs £475 plus VAT

How is a HotBox used in the composting process?

The Hot Box is being used mainly by schools, businesses and institutions,  that produce a lot of waste for composting. The unit it usually used as a maturation container for one of the our food waste recyling composting machines.

The Hot Box is generally used for maturation following an ‘in vessel’ stage .  Larger woodchips can be sieved out (from a tumbling or other in-vessel system using large wood chips) to go back to the first stage composter. The material is then perfect for the worms, for in effect it becomes a wormery.  Worms naturally invade compost heaps at the maturation phase, and they love the large, warm surface area that the Hot Box provides throughout the year.

Ideally, two or more boxes are used, depending on the volume of materials needing to be processed. When one is full the other one is filling and then the first one can be emptied. The front has removable slats, which makes emptying easy.
