| Abstract | The waste minimization and energy conservation assessment was done in a pineapple canning factory. The factory generated approximately 1700 m3 of wastewater and 155 tons of pineapple shell per day. The factory consumes approximately 3,468,768 liters of fuel oil and 4,870,820 kWh of electricity per year. It was found that technology modification, good housekeeping and process execution and on-site reuse, recycling and waste segregation are the effective waste minimization measures. The technology modification are modification of the sedimentation basin for fruit washing unit, installation of cover on wastewater line for peeling, use of pressure washing nozzles for slicing and modification of syrup filling table. Good housekeeping and process execution are proper cleaning method training, awareness of solid waste fall and collection, proper water use and proper production scheduling. The on-site reuse, recycling and water segregation are recycling of fruit washing water, reuse of condensate, recovery of squeezed juice from pineapple shell and segregation of wastewater from concentrated juice plant. It was found that 30 percent of water can be saved, 360 m3 of syrup can be recovered and 7,280 m3 of juice can be extracted per year via implementaing these measures which were proven to be economically incentive with approximately 1. 7 million baht saved per year. From the energy conservation assessment, it was found that boiler adjustment, steam pipe and valve insulation and equipment insulation are effective tool to prevent energy loss from the production process. It was found that 13.5 percent of fuel oil can be saved per year by implementing these measures which were proven to be economical incentive with approximately 200,000 bahts saved per year. |
