HOTBIN Composting

Tony Callaghan is the inventor of the patented HOTBIN composter. Following successful launch of business back in 2011, the patent and worldwide rights were assigned (sold) to DS Smith plastics in January 2016. We wish the HOTBIN team every future success.


Our latest project is making “super” compost and other related soil improvement additives such as biochar and colloidal humus. To learn more visit


Our work on compost odour filters and biochar has led us into the production of charcoal (a type of activated carbon). Charcoal has a long history of use in filtration of water, air and gas. We are happy to discuss supply of charcoal and activated carbon
