HotRot is a mechanically “active” system that produces a highly stable compost. According to the technology’s manufacturer, based out of Christchurch, New Zealand, HotRot can meet new Canadian Council of Ministers of the Environment (CCME) environmental quality guidelines with little or no storage. “HotRot’s strengths lie in its ability to deal with highly putrescible waste, where environmental controls are absolutely essential,” explains Dr. Peter Robinson of HotRot Organic Solutions. The company offers a contractual odour-free guarantee, and systems produce no leachate and remove excess moisture as a clean vapour. “HotRot also has the advantages of a much smaller footprint and low labour requirements and produces a highly stable compost,” adds Robinson. Site works needed to support a HotRot plant are minimal, and the equipment can operate outside, even in very cold climates. The technology has found applications in various countries for processing sewage grit and screenings, biosolids as well as source separated organics from municipalities, institutions such as universities and theme parks, and remote mine and construction camps. Systems can be designed to process between one and 100 tonnes per day.
