Several studies have been investigated to find effective ways of minimizing COP, (Brezet and Schelleman, 1995) however literature do not evidence any use of cleaner production, a waste zeroing system. This study was aimed to evaluate the cleaner production concept in rice and coffee processing sectors, as a solution for minimizing COP. Cleaner production is the continuous application of an integrated preventive strategy to processes, products and services, to increase eco-efficiency and to reduce risks to humans and the environment (Brezet and Schelleman, 1995). Methodology Using Ruhunu Foods (Pvt). Ltd flour and spice processing factory as the host, the production process was analyzed to identify possible waste streams and their causes. Using direct measurements and material balance calculations, the waste streams were then quantified. This was done during a period of one month batch production from both processing sections. The quantified wastes were then expressed in terms of their monetary value. Significant waste streams were identified using Pareto analysis. Control measures for them were suggested using CP philosophy and CP techniques as a guide. Ten minute power logger data were obtained from both hammer mill machine and flour mill machine. Then the power factor correction was done to find the payback period for the energy saving process. Result and Discussion According to the findings of this study, both avoidable and unavoidable wastes occur in the coffee flour manufacturing process. The average loss per batch of money due to avoidable wastes of red rice, white rice and coffee processing are respectively LKR.3885.07, LKR.7612.5, and LKR.1529.39. Significant waste streams which contribute to this monetary loss are stuck red and white rice flour and coffee powder inside the milling and grinding machines (89.75%, 93.59%, 97.46%), rejected coffee beans (59.51%). The possible control measures for these waste streams are good housekeeping, better process controlling and equipment modifications. Ten minute power logger data were indicted both flour mill and hammer mill have a low power factor. According to the power factor correction both milling process takes less than 4 years payback period to recover the cost of the energy upgrade from the energy savings. Usage of premium efficiency motors and capacitor banks will save the energy. Immediate implementation of cleaner production will uphold the company image and increase the quality, productivity, worker satisfaction and profit.enScience and TechnologyTechnologyAgricultureExport AgricultureCrop ProductionNational Cleaner ProductionOther
