Since china exports so much and we export so little, rather than send empty shipping containers back to china, we fill it with our garbage and send that back to china to recycle.

At one time this was true of the trucking industry, too. Trucks would haul goods to a city, then carry that city's trash back out. It was considered better than running a truck empty.

Then they started doing it with food trucks, and the regulations came.
