OR...they could do it like Bejing China. Haul it out to the fields where it is used as fertilizer. Grow fruits and vegetables then sell it to North Americans because they are so stupid they buy ANYTHING because it is a dollar cheaper than what they make at home. You know...the home where they have all those silly regulations telling them what they can and cannot do with sewage, and nuclear waste, and chemical waste etc etc etc.
