HotRot 3518 Composting Unit Installed in South Africa

About the HOTROT 3518 Unit

The HotRot 3518 is the largest single unit and is constructed from pre-cast concrete or pre-fabricated steel sections. Designed to be used by larger municipalities and sewage treatment plants, multiple units can process any quantity of organic waste but HotRot generally recommends plant of less than 180tpd to minimise transportation distances and local impacts.

The HotRot 3518 is designed for outdoor operation; additional insulation (winterisation) is available for extreme climates.

Locating any feed hoppers within a waste reception building with the HotRot units outside would be normal. Product conveyors can discharge into a storage building or open temporary storage bunkers.
