CompoCloset™ | S1 Dry Flush Sealing Toilet

This is a dry-flush sealing toilet — not a composting toilet

S1 uses a sealing process rather than an internal composting chamber.

Urine is diverted before the solid waste is enclosed in a liner, reducing the amount of material that needs to be sealed and keeping the sealed solids drier.
