The Purchasing Manager of an Engineering Company in Chattanooga is about to order some office equipment for their new office in Red bank. Due to a recent top-management decision to promote sustainability in all of the company's business operations, the Purchasing Manager is in consultation with the Environmental Manager to purchase environmentally-friendly equipment. They are investigating whether to purchase a photocopier, a printer, a scanner and a fax machine separately or to purchase a multi-functional device (MFD) with all the needed functions. You are the only engineer in the company with a sustainability background and so you have been assigned by your Environmental Manager to provide some advice as to which option is environmentally friendly in terms of carbon benefits. The following information has been made available from the office equipment suppliers to enable you conduct the relevant life cycle analysis. Further information: The weight of the MFD is 300kg. The company usually uses the equipment for 10 years before they are sent to either recyclers or remanufacturers. Therefore, you need to conduct your comparative assessment for 10 years use of the equipment. The emission characterization factors for remanufactured cartridges, new cartridges, raw materials, tonne-kilometres travelled (tkm), and Red Bank's electricity supply are hypothetically 2kgCO2e /cartridge, 5kgCO2e/ cartridge, 15kgCO2e/kg of raw material, 1kgCO2e/tkm and 0.6kgCO2e/kWh, respectively. (a) Conduct a life cycle assessment based on the information provided and determine the carbon footprints for the 2 options. Include all major assumptions made during the life cycle assessment. (b) Beyond life cycle assessment, discuss your choice of the office equipment based on at least one sustainability engineering strategy (e.g. cleaner production, industrial ecology, and green chemistry)
