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.

I suspect the people with a million orange peels to dump are also the people who are experts in exactly how the various parts of an orange degrade with time and that when the plan was concocted they did so knowing it would likely work but they didn't write it down and have since left. Basically the same as legacy code. You see this all the time in the physical world. "why did those morons choose X for Y". Well, 20yr ago the product served Z and at the time that industry cleaned their factories with some other chemical than what they use now and therefor X was the right choice.

People who know their industrial project will F-off and create a dump are the ones who go through the process, pay for the bullshit surveys and studies, get the permits and whatnot and document the whole thing fastidiously. Because those are the things you do to ensure that you are not the bag holder at the end of it all.
