Global Composting Solutions is based in Christchurch and as their name suggests they provide sustainable, automated, aerobic composting solutions to companies around the world. The HotRot™ vessels central to the company were initially designed and commercialized by a JV group and Mace engineering for the New Zealand Wool Board as an environmentally friendly solution to their waste products about 15 years ago. Today Global Composting Solutions o er a turn-key solution to di icult organic waste streams. They work with clients to identify their needs; then design, build and install the system ready to be monitored electronically. They provide an integrated solution which takes organic waste at one end, and in two weeks turns it into safe, high-quality compost ready for immediate handling and use. Their smallest vessel called COMET was created in response to client needs and can handle up to 50 kgs a day. It’s put to good use for example at Pourewa in Auckland where the compost it creates goes back onto the gardens. “With the iwi it’s regenerating their soil for the next lot of crops,” explains Andrew Green, company MD. “It’s still in pilot stage, but the longer-term goal is to eventually upsize and put in a bigger vessel to increase the diversion from land ile to create a valuable end product. Once proven, the idea of then putting a bigger vessel into more of their maraes is a great sustainable option.” This relatively small, compact, rectangular Comet vessel is ideal for places like university cafeterias, or schools, because the enclosed composting vessel eliminates any of the odour which compost typically creates. It’s the most recent iteration of the HotRot vessels with the bigger 1206 (1.2m diameter x 6m long) handling up to 500kgs a day, and the 1811 (1.8 diameter x 11m long) handling up to 2,500kgs a day and the largest vessel the 3518 ( 3.5m x 18m long) handling 10,000 KG per day, all of which are already in use around the world. “Melbourne Zoo has an 1811 which handles all their animal waste, any deceased animals, straw, café waste and anything else that’s compost worthy. They make enough compost to ill the zoo’s needs and they sell the excess to the community,” says Green. “The Dubai Safari Park has 3 units to handle all their waste. With the inal product used to regenerate the land and gardens around the park” The 1206 is also put to good use by a wide variety of companies around the world with smaller but still signi icant waste to deal with, ranging from an eco-friendly tourist resort in Fiji to a Whiskey Distillery in Kentucky, USA. ‘Waste is a global issue,” says Green, “and people are struggling to ind solutions, so that’s where we come in with our sustainable, environmentally friendly systems. Be-spoke and designed to meet their speci ic needs.” COMET having an impact HotRot guarantees that plant designed, installed and operated according to our guidelines will not result in odour problems for your business.
