To recycle human wastes on the Moon (meaning poop, etc.), the liquids could be drained from solid wastes for other vital uses and the resulting condensate could to be used as little bricks in a Lunar or Martian environment. This could make a external cover protection for static modules against micro-meteor, dust or tempests.
Furthermore little asperities on the bricks could help hold them in place to build external protection walls.
Another use for theses solid and drained waste bricks — from 2024 — is to use it to pave a way on the ground for exploration or vehicular comfort and material resiliency and preservation.
