It is urgently necessary for factories to balance energy cost reduction and stable operations. Factories face three major challenges.
1. For reducing environmental impact: to implement environmental measures related to water, air and soil throughout the factory, including production equipment, facilities, and energy supply facilities, and address energy issues through energy conservation and creation.
2. For ensuring security and safety: to install disaster prevention equipment, emergency broadcasting system and security systems.
3. For improving management and production efficiency: to streamline component mounting machines or production line operations and utilize ICT.
When considering energy measures for factories, it is important to see them both from the perspective of construction/facilities and from the viewpoint of manufacturing. At the Himeji Plant of Panasonic Liquid Crystal Display Co., Ltd., we consistently manage planning, design, construction and maintenance in order to achieve energy conservation and stable operation 24/7/365 through a fusion of water, air and energy technologies. Additionally, our daily fine-tuning is enhanced by understanding the overall situation of our production systems and carefully checking any excessive power consumption at our facilities.
Instead of wasting heat from the compressors used at our plants, we recycle it to heat the pure water that is essential for the production of liquid-crystal panels, thus leading to reduced air-conditioning load and energy conservation. When recycling wastewater, we further minimize energy usage through energy-saving measures. Additionally, we've developed technology for recycling even the chemicals used in production at our plants, further reducing costs.
By supporting continuous, constructive production activities through LCS (Life Cycle Support), we have reduced CO2 emissions from production activities at the Himeji Plant by approximately 33%. We have also reduced water consumption by approximately 35% (relative to a conventional plant), thus contributing to our efforts to achieve 100% water recirculation. Moreover, significant reductions in the cost of buying new chemicals have contributed to a decrease in the overall cost of production. We are also promoting the introduction of natural energy by installing photovoltaic panels.
We have systematized the environmental operation know-how accumulated at approximately 350 plants group-wide. We support energy conservation and comprehensively provide environmental energy technologies such as wastewater treatment, fresh water production/wastewater recycling, waste gas treatment, resource recycling, soil and underground water purification and photovoltaic power generation. We support various industries, including the manufacturing, transportation equipment and pharmaceuticals industries, aiming to achieve green factories with zero emissions.
At the "Eco Visualizing Showroom" at our Kasugai Plant, we exhibit green factory know-how and examples. Additionally, we opened another "Eco Visualizing Showroom" at the plant of Panasonic Manufacturing Malaysia in September 2011. At this location, we present Panasonic's environmental management and the process for realizing a green factory as the Total Environmental Package Solution for Factories. We introduce systems that facilitate the integrated management of energies at multiple locations as well as systems that link production equipment and motors according to production conditions. We thus offer solutions, including energy-saving support services for plants, on a global basis.
