But what waste do they have that they wouldn’t want to eliminate for production reasons? They assemble cars from parts they buy. A lot of times these parts come from smaller machine shops. A pallet of parts comes in, it gets out on the car, pallet returns to the supplier for the next load. I’m not sure why people are confused here. It’s not like they want the parts to be individually packaged.
Caveat: I’m not a manufacturing expert but I have met some of these machine shop people.
