The problems with waste are clearly a short-term issue caused by unexpected growth. If they can absorb ~70% of their acid whey by product by mixing into nearby farms, then given the sheer amount of livestock in the US, you can definately absorb all of it if you solve the distribution/logistics problems. Really, all of the solutions the come up with will work. None of really have a real scaling issue, but they do require capital and have lag-time, which apparently were not sufficiently considered. The problem here isn't that 'oh, there's a river of this "toxic" waste that we don't know what to deal with'. The problem is 'oh, we've tripled our production without having a solid plan on waste disposal, and we don't want to pay more to truck this stuff to further farms'.
