Now integrated into Jamaican Castle's 1.1 update for Fertile Fields!
A small compatibility patch between Fertile Fields and Dub's Bad Hygiene which lets you process the latter's fecal sludge and biosolids into the former's raw compost and fertilizer, respectively. Probably overpowered since it adds recipes for easily getting rid of sludge, though I think I've managed to balance the actual compost and fertilizer recipes well.
Non-Steam version available here.[github.com]
Production paths
1. Make Ash at the crematorium or burn pit from fecal sludge -> use the new compost recipes including ash which are more efficient -> produce fertilizer normally
2. Put Biosolids into a crematorium to convert them directly to fertilizer
Load it after the required mods.
