Sažetak
The aim of the present research was to determine the potential of two organic materials, sewage sludge and olive pomace, in biochar production for application in agricultural purposes. Research was carried out on the assumption that biochar addition to agricultural soil, through carbon sequestration, would reduce CO2 emissions, while at the same time increase soil fertility through the addition of biogenic elements. The studied materials were converted into biochar using the Kon-Tiki open-type system. Pyrolysis temperature measurement was performed using a NiCrNi thermoelement, and ranged from 520° to 580°C. The chemical composition of sewage sludge, olive pomace and two types of produced biochar was determined. Chemical composition results showed significant differences in the quantities of individual elements in the produced biochars, compared to the raw materials used. In the starting organic materials, the average amount of carbon was 44.5% in sewage sludge and 55.4% in olive pomace. The average amount of carbon in sewage sludge biochar was 23.2%, while in olive pomace biochar was 77.1%, presenting a potential for carbon sequestration in the soil. We can conclude that the investigated organic materials are suitable raw materials for biochar production using the Kon-Tiki system and their application as fertilizers for agricultural purposes will be further investigated.
