I finally made it to Fulgora after taking a break for a few weeks. I spent a day in editor mode figuring out ratios of recyclers for each product and byproduct from scrap and was able to put together a system that should never clog from 1 belt of scrap, although that will probably fall apart as soon as I research recycler productivity. Luckily, I found a pretty large island not too far from the starting island, so space isn't much of an issue, but I am setting up manufacturing for elevated rails since I expect the scrap to run out pretty soon.
