Aroonsrimorakot, Sayam | Yuwaree, Chumporn
Not only the ancient industry, but printing industry is also an important one of Thailand. From sampling factories review [1]-[5], there are three aspects of environment problem of productive process that are detailed as follow: air pollution, wastewater, and energy losses. This research has the purpose to identify the use of resources and pollution point of sources including the causes in processing of offset packaging printing factory in order to applies the principles of clean technology for air pollution reduction, standardization of waste water and electrical power reduction in a packaging and printing factory. The case study employed was a packaging and printing factory with a capacity of 2,241.2 Ton/Year. The proposal for cleaner technology is to apply an air-conditioning system with an Evaporative Cooling System that reduces power consumption of 149,841.79 kWh/year or 39.66% with saved costs equivalent to 14,210.49 USD/year. The energy saving air-conditioning system also reduces intensive inhalants in the air concentration of the production area (printing area) to reach the standard criteria. Waste water separation for appropriate water management helps save a total of 119.69 USD/year and reduces waste water by 0.56 m3/year or 0.8%. Construction of a waste water treatment system in the first year enhances the lawful processing which can save 6580 USD/year and reduce waste water by 4.83 m3/year or 6.96%, and provides water recycling of 45.201 m3/year. A year after cost expenditure for the system is 1246.17 USD/year, with, when compared to delivering waste water for eradication, can save 241,215.03 Bath/year.
