Wastewater-to-Hydrogen

Wastewater-to-Hydrogen is a compact, scalable facility designed to convert wastewater into hydrogen. It can handle the wastewater produced by about 8k residents. Available from midgame because it uses pipes up to 450. The system can be expanded by adding copies of the unit (see screenshot 3) and connecting them to the main pipeline network (see screenshot 4). Connection is done through a pipe balancer — both for water input/output to the settlement and for linking multiple units. The upper balancer manages clean water, and the lower one handles wastewater.

Note: If the settlement generates more wastewater than the facility can process, the first storage becomes full due to the excess, a notification will appear indicating the need to build an additional treatment plant.

Resource Productivity:

Maintenance staff: 130

Note: To create a small initial stockpile of Filter Media, you can temporarily enable the boost for both crushers.

What to do with other types of waste? They can also be converted into useful resources.

Biomass and Compost can be turned into Diesel and Gold using the BioSoil Diesel Cell (Dirt into Gold):

As for Waste incineration, I’ve integrated it into the Industrial Gas Cleaner setup, which also extracts Water and other resources from seawater:

Waste as a path to a cleaner environment.
