Abstract

The increasing demand for local products is forcing farmers to expand their production, which also increases the waste generated by the animal husbandry process. The utilization of organic waste from livestock farms is a serious task for farmers, and they need to look for alternative methods of treatment. In this paper, we consider the possibility of applying sludge from a pigs farm for fattening. Samples of dried to room humidity sludge taken from a pig manure metal lagoon were examined. The purpose of the study is to evaluate the prospect of sludge as an alternative fuel for the pig farm. A thermogravimetric (TD) and differential thermal (DTG) analysis method was used to investigate the sediment. These methods of analysis were used because of the wide range of information provided and the possibility of qualitative and quantitative analysis. The types of phase transitions in the processes of heating and cooling, the temperature interval, the time for their flow and the amount of heat absorbed or released are investigated
