Bar chart with an x-axis showing dollars in increments of 50 cents, starting with negative 1 and going up to 3.50; y-axis shows eight process areas. The chart shows the cost contributions for seven parameters: Capital Recovery Charge, Grid Electricity, Byproducts and Credits, Raw Materials and Waste, Total Plant Electricity, and Process Electricity. The chart shows that feedstock costs dominate the overall system economics.
