Cleaner Technology Application in Printing Factory (Offset Lithography System)

AbstractNot 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

Green Logistics (GL) for Environmental Sustainability: A Review in Search of Strategies for Thailand’s GL Management

There is an increasing interest among both researchers and environmental management practitioners, in the topics of environmental sustainability, and logistics operations, as well as strategies which combine these two concepts as current logistics operations have many negative impacts on the environment. This article offers a systematic literature review of publications in the area of Green Logistics (GL), the significance of GL, and strategies adopted for the best performance of GL management in various countries for environmental sustainability, between the years 2010 and 2022. The study is presented by organization into the sections of introduction, green logistics and its importance for environmental sustainability, strategies for the development of green logistics in Thailand, and a conclusion. Some of the strategies obtained from the literature search for the development of green logistics in Thailand are management of transportation, storage, packaging, and loading and unloading; development of green warehousing; evaluation of logistics operation systems, publicity, promotion, and training; the use of integrated information technology to increase awareness of green logistics, and reverse logistics; and collaboration of organizational and stakeholder pressure. The article is expected to be beneficial to logistics services providers as well as the general public, in developing and implementing green logistics strategies to achieve a sustainable environment for the overall well-being of mankind on a global scale, socially, economically, and environmentally
