| Abstract | This research aimed to analyse biomass loss and total pollution due to pre-harvest burning of sugarcane by using the Closed Loop Combustion System Model for investigating its effects on the environment in order to support non-sugarcane burning promotion. The results showed that 16.61 tons/ha of sugarcane leaf were burned, or 16.65% of sugarcane yield. Total heat energy loss was 292,712 MJ/ha which was estimated to equal electrical power 6,118 kW-h/ha. The plant nutrient contents in sugarcane leaf and ash were not found to be significantly different. Nevertheless, an economic analysis indicated that the employment of a practice that does not burn sugarcane might reduce somewhat the cost of major fertilizer (NPK) inputs as compared to pre-harvest sugarcane burning. The amount of the pollutants CO, NO2, SO2 and CO2 in the air caused by burning 100 g of dried sugarcane leaf in the Closed Loop Combustion System Model was 4,406, 43.7, 104 and 154,055 mg, respectively, and the weight by area was 731, 7.26, 17.3 and 25,592 kg/ha, respectively. This practice would likely lead the pollutant concentrations increasing in our atmosphere, which could cause worsened allergies or death for humans and harm to other living organisms such as animals and food crops. Moreover, the CO2 released by burning sugarcane contributes to global warming. |
