2. Two confidential process data sets are shown in the fig- res below. Process A uses input of raw materials (RM) X and to produce Product A, while Process B uses inputs of RM X, RMZ, and Product A to produce Product B. Use the data sets for the two proprietary processes to prepare a combined data for 100 kg output of Product B that protects the details of the individual processes. 40 kWh 2000 m3 nat gas 3. Identify a relatively simple metal containing product sys- tem that consists of no more than a half dozen materials. De- velop a process flow diagram for this product system tracing major life cycle processes that encompass material production, manufacturing, use and service, and end-of-life management stages of each material. Label the key unit operations (e.g., mining, pig iron production in blast furnace, steelmaking in basic oxygen furnace, and stamping) and material flows across the life cycle (iron ore, steel, stamped steel, and scrap steel). 90 kg RM X- Confidential Process A 30 kg RM Y- 20 kg waste 120 kWh 500 m3 nat gas 10 kg RM X- 25 kg RM Z- Confidential Process B 70 kg Product A. 100 kg Product A 100 kg Product B 5 kg waste per 100 kg per 100 kg Product Product A B Inputs (RM=raw material) kg RM X 90 10 kg RM Y 30 kg RM Z 25 kg Product A 70 kWh 40 120 cu meters natural gas 2000 500 check total kg inputs 120 105 Outputs kg Product A 100 kg Product B 100 kg solid waste to landfill 20 5 check total kg outputs 120 105
