The air quality board recently informed Coffee Roast, a small coffee roasting firm, of a complaint regarding the smoke from its roaster  Recently enacted air quality regulations requires machine roasting more than 10 pounds of coffee to be equipped with expensive smoke-dissipating afterburners  The firm, however, roasts only 8 pounds of coffee at a time
Nevertheless, the company has decided to purchase and install an afterburner
The cost to the firm of an afterburner is less than the cost of replacing its roaster with a smaller one.
