A manufacturer can make coating material Q by two different routes. Both routes form other products as well as Q.
Why could choosing the route with the higher atom economy reduce the cost of making Q?
Less Q is lost during transfers between vessels
Fewer reactants are used up in side reactions
A larger mass of by-product is available to sell
Less money is spent on treating and disposing of waste
