Synthetic Sausage Casing

Sausage might intended to be a meat trimming byproduct. But I love them. Colonist should have plenty of them but meat triming is not enough for colonist to enjoy.
Process might be more tedious as you have to mince the meat and collect collagen to make sausage casing. and you have to mince the meat that go into casing to make sausage too. but I want colonist to enjoy them.
