I figured out a way to collect all the lost items on this build. I had noticed all the lost items were falling between the belts and then were getting kicked out by the movement of the belts.
I decided to use fans to blow the lost items once they fall through the belts on to another belt that sent the items up one of the belts going to the composter hoppers.
I used an external rotation power source that was close by to power all the fans at max rotation. It works great no more lost items floating around my build.
This build is great and easy to fix when things go wrong.
