Q: What eco-friendly tech is used on Century Victory?

A: Yes, the Century Victory uses a closed-loop vacuum toilet system and an advanced onboard wastewater treatment plant that processes all black and grey water to near-drinking-quality standards before discharge, complying with China's strictest Yangtze River pollution regulations.

From a plumbing standpoint, the vacuum toilets pull waste with only 1 liter per flush—compared to 6–8 liters in a standard gravity system—saving massive amounts of fresh water. The treatment plant uses a biological aerobic digester followed by UV sterilization and a membrane bioreactor. The output water is clean enough for technical reuse (deck washing, engine cooling), not for drinking. The system also has a holding tank so nothing is dumped even when docked at sensitive areas like the Three Gorges.

Actionable hygiene advice: You can flush standard toilet paper in the vacuum system without clogging—the paper breaks down quickly. But do NOT flush wet wipes, napkins, or sanitary products; they will jam the vacuum valves and require a manual unclogging. If you see a "flush only paper" sticker, that's not a suggestion—it's mechanical fact.
