Abstract
Recirculation of nutrients to agricultural soils is especially important for those produced from non-renewable resources, such as phosphorous (P) obtained from phosphate rocks. The reserves of this mineral, mostly located outside the European Union (EU), are foreseen to be depleted in a range of 100-400 years [1]. In 2012 EU imported 88% of the phosphate rock consumed. Since only about one fourth of the P applied to agricultural fields is actually recycled today [2], innovative recycling and re-use concepts need to be developed and adopted. Low-temperature gasification allows an energy production from biomass resources with high contents of low melting ash compounds – often shown to be a source of boiler operational problems in more traditional incineration. Materials like sludge, have a high P content, which should
preferentially be recycled back to agricultural soils after this thermal process. However, major concerns are its heavy metal content and the low plant availability of P; hence, a separation of phosphorus from the bulk bioashes and heavy metals would be beneficial.
