Your figure should in" rel="nofollow">include a key to identify products, processes, emissions, and energy usage. Your figure should also identify three peer reviewed LCI data sources. Breakdown of poin" rel="nofollow">ints as follows: a. The process flow diagram should fill an entire 8.5x11 sheet of paper. See the examples in" rel="nofollow">in class for reference on what constitutes and ‘A’ for fillin" rel="nofollow">ing the sheet. (3pt) b. A key with products, process, and emissions should be clearly labeled and appropriate for your product. (1pt) c. Your product should be clearly identifiable. (1pt) d. Include THREE numbers quantifyin" rel="nofollow">ing in" rel="nofollow">inputs or outputs on your process flow diagram. Please circle or highlight these numbers on your diagram so that we can easily fin" rel="nofollow">ind them for gradin" rel="nofollow">ing. For example, how much CO2 is emitted from a corn farm (gCO2/acre), or how much organic waste results from a chicken farm (gwaste/farm) or how much wheat is required to produce one bun (gwhat/bun). Include units for each number. You must cite your resource (google, the web is ok for this activity. You have to get started somewhere.) (1 pt for number, 1 pt for unit, 1 pt for proper citation) (9 pts total) e. On page 2, identify ONE change to your system that might result in" rel="nofollow">in improved life cycle environmental impacts. Clearly state the change, the results you expect from makin" rel="nofollow">ing the change and the pros and cons of your improvement in" rel="nofollow">in 5 sentences. (6 pts)
