6. An environmental load study compares Incandescent, CFL and LED light bulbs. Energy consumption for the 3 bulb types in M1/20 million lumen-hours is: 15100, 3950 and 1760 respectively The weight of minerals used in the product specified in g/20 million lumen-hours are: 600, 300 and 200 respectively The study is interested in emissions to the air (CO) and emissions to the soil clandfill). The bulbs are sent to a landfill after usage. a. What is the goal of the study b. Which Functional Unit should be used? c. What is for each bulb type the amount of "minerals/functional unit disposed in the ground after usage? d. What is for each bulb type, the amount of energy/functional unit consumed? e. What are for each bulb type, the "air emissions/functional unit"? The following conversion factors are to be used: 1 M) - 0.28 kWh 1 kWh results in 0.61 lb. of CO
