Because of the high temperature of roasting, I am suspecting at the moment that it might be close to charcoal, but obviously different because it has water slicking properties. I will have to look into how they get these numbers. I found a roaster who will give me some, but they are an hour away and only open during my busiest working hours, so it will be hard to get any in.

The only place to keep them is under a sink in a cabinet and due to a lack of air flow they are starting to get a bit of white mold. Anyone see a problem with this? My plan is to fill up a 2 gallon bucket (half way there) and take it home to mix with my shredded leaf pile that's a bit over cubic yard of material. I assume the mold won't be a problem but thought I'd check to see if anyone had any insight.
I don't think it will make a difference in the compost. If you intend to keep them moist in a dark space til you have enough, I would expect that the mold mights spread to other unwanted places or just start to make a stink.
I have also had great success, accidentally last winter, in anaerobic decomposition of excess compost. I had too many mostly greens (the grounds are browns, but I usually have too much veg), so I stockpiled for a few months until the snow melted and I cleaned up the rest of the fallen leaves. I had amazing compost in not much more than a week.
