First thanks for this plugin, it's been on my servers all the time, so simple, so amazing, less clutter thrown to the ground means healthier server.

Now, I have to ask... can diving gear and plastic bottles be hacked into the data/jason file so they can be recycled also (not being bp)?

I secretly tried:

"diving.fins": 25,
"diving.mask": 25,
"diving.tank": 25,
"diving.wetsuit": 25,
"smallwaterbottle": 10,
"waterjug": 10

Yeah, well, that didn't work ^^;;;
But those are the biggest offenders, so here goes:
Can you make a sibling plugin called something like "Recycle Crap", so we can have a cleaner environment? :D <3

I have previously considered something for the scuba gear.  Might tackle this if I have some spare time, and make something to allow recycling of all items that normally can't.
