Satisfactory in 40(ish)--pt21

Quick and Efficient playthrough in Grassy Fields.
We got pure aluminum ingot (probably the best recipe for Aluminum simplification--removes silica intake, but not output, from the production chain) but didn't get Sloppy Alumina (removes silica output which a sink can do just as well). No biggie, let's make our aluminum factory. We use a priority junction to make sure our pipes don't flood instead of using the waste water in a coal gen. or a wet concrete factory.
