A chemical manufacturer wants to try a new process for making a highly refined form of nickel(II) oxide from nickel(II) nitrate and sodium hydroxide as reactants. The byproducts (other products other than nickel(II) nitrate) are HNO3 and sodium nitrate. The product is used in making rechargeable Nickel Metal Hydride batteries (NiMH). The raw materials cost $2,000 per metric ton for nickel(II) nitrate and $900 per metric ton for sodium hydroxide. A metric ton is equal to 1,000 kg. The first new method uses twice the mass of nickel(II) nitrate as sodium hydroxide and has a 90% yield, but refinement & waste processing only costs $25 per ton. The other new method uses five times the mass of nickel(II) nitrate as sodium hydroxide, has a 99% yield, and refinement/waste processing only costs $10 per ton. Your group has been hired as a consulting firm to help the manufacturer decide whether to adopt one of the new processes and if so, which one to choose. What is your advice to the manufacturer? How did you reach your answer? What actional results (data or calculations) can you share with this manufacturer to help them decide on the best path?
