A plant is producing 10,000 metric tons per year (10 kMTA) of a product. The overall yield is 70 per cent, on a mass basis (kg of product per kg raw material). The raw material costs $500/metric ton, and the product sells for $900/metric ton. A process modification has been devised that will increase the yield to 75 per cent. The additional investment required is $1,250,000, and the additional operating costs are negligible. Is the modification worth making?
