1. An algal protein processing plant could realize $7.7MM/yr annual income assuming 1.1MMkg protein/year and product revenue of $7/kg. The engineering design group came up with an estimated purchased equipment cost (PC) of $1,940,000. Use a Lang factor of 2.20 to determine the FCl for this plant, and 13/87 split of the fixed capital investment to get the total (TCI) and working capital investments. The annual operating cost (AOC) of this process is $5,610,000. FCl depreciation can be calculated over 10 years with 5% salvage value. The corporate tax rate for the project is 40% of the annual taxable gross profit. a. Determine ROI b. PBP c. Calculate the protein production cost in $/kg protein
