Hey, I had a few requests from a few of my players to add storage adapters to the recyclers, is this possible?

Yes it is possible, but not planning to add this feature to this plugin.

There is already a way to give the ability to your players, but the catch is it's a paid plugin : "extended industrial" by bmgjet. I don't want to drop links here but a quick Google search will find it. If your players like to use the industrial automation, this plugin will go down well, as it adds the adapters to a massive range of items.
