Sulfur

Overview
Sulfur is a byproduct that can accumulate faster than it is consumed, especially once refining lines are running at a reasonable scale. When output exceeds demand, excess Sulfur must be disposed of to keep refining arrays from backing up and stopping. Because it is a byproduct rather than a primary output, managing Sulfur surplus is mainly a logistics and waste-handling problem.
Common ways to handle excess Sulfur include storing it for later trade, converting it into landfill material, burning it as a solid fuel, or dumping it after mixing it with Water. Each option has a different cost profile: long-term storage can be profitable if the surplus is traded to a neighboring village, while landfill conversion consumes Limestone, which is a finite natural resource on the island. Burning Sulfur produces energy, but it is less pollution-efficient than the other disposal methods. Direct dumping is the simplest option, but it is generally undesirable because it creates a high amount of pollution. Mixing Sulfur with Water before dumping allows byproduct production to continue, but it still has the same Water Pollution as the corresponding solid-waste route.
- If you have enough storage, stockpile Sulfur and export it in bulk for profit.
- Use Mixer-based disposal only if you can afford the extra input cost.
- Burning is useful when you need some energy and want to avoid the worst pollution outcomes.
- Liquid dumping is the quickest emergency relief, but it should be avoided in normal play because of its pollution output.
- If Sulfur production is expanding, plan disposal capacity early so refining chains do not stall.
