From TFA it sounds like they had no idea, given how often they repeat how surprised they were at the outcome. So it sounds like an uncontrolled experiment, let's dump thousands of tons of food waste here and hope for the best.

Also, it's a sample size of one. There could be 20 other non-published stories where something similar was tried and it turned the place into a toxic wasteland. It's a great success story but I can see why people would be nervous with a food company dumping its waste next to a national park.
