In 1980s change in meat and bone meal production technology led to the spread of BSE and massive culling of beef cattle in many countries. Adding meat and bone meal to animal feed was banned, but animal carcasses still have to be disposed of. In this work the operational parameters and efficiency of a utilisation process for raw meat wastes and emissions of CO, NOx , SO2 and VOC were studied. A 5 kWth fluidised bed combustor was used and tests were repeated in a 150 kWth (KFD-s14u) boiler, with combustion of meat wastes (biomal). With combustion, the heat generated can be recovered, the meat waste is completely burned, bone pieces mineralised and fragmented and flue gas composition is similar to that with coal alone. The potential of the technology for raw meat waste utilisation has been demonstrated on a technical scale, with waste throughput of 180 kg/h*m2 (with respect to distributor area) and factors limiting the combustion efficiency have been determined. An installation (up to 3 MW thermal) has been designed for the utilisation of 500 kg/h of raw meat waste in cocombustion with coal. The installation should fulfil the requirements with respect to waste utilisation efficiency and thermal energy production.
