How the hell does it even make sense to, Send them to china and then send them BACK again! The delay in shipping time must cost business money
There are two things that need to be kept in mind to understand this:
1) When it comes to any kind of large-scale, industrial-type of production, the fundamental principle is that nothing should get wasted, because the waste can be re-sold and re-processed. One man's trash is another man's treasure.
2) The food processing industry heavily relies on the manual human labour. Despite the fact that technologies exist to automatically separate meat from bones (or blend them together), a machine cannot tell the difference between the different parts of a chicken yet if you feed it the whole trunk. A worker must separate different pieces first (because each part is valued differently) and then sort them accordingly.
So, given that:
a) the cost of labour is lower in China, and
b) the demand for the post-processed trash is greater in China =>
=> it makes for a perfect business case to do it the way it's proposed in the article as all the decisions the corporations make are profit-driven.
Finally, the savings from the manual labour in China must offset the cost of shipping it all back and forth. They must have done their homework.
Why they cant do all this in the US I do not know.
They can and they do. But the margins of doing it through China are higher and the CEO's want their bonuses for their
extra work extra profit that they've showed the shareholders.
