Bio’loo : Bio’Loo: Enzymatic Sanitation for Mines, Tunnels & Underground Sites
Bio’Loo is the only industrial enzymatic sanitation system specifically designed for mines, tunnels, and underground construction sites, offering several months of operation without routine maintenance or emptying.
Unlike conventional chemical toilets, it incorporates a compact biological enzymatic treatment system using Sub’Zyme, a 100% biodegradable and non-toxic solution. It breaks down organic matter with every use, without harsh chemicals or unpleasant odors.

The Industrial Sanitation System Designed for Underground Environments
Unlike conventional chemical toilets, which require emptying every 1 to 2 weeks, Bio’Loo can operate for up to 12 months without intervention—meaning up to 26 times less maintenance.
The Sub’Zyme enzymatic solution is 100% biodegradable and non-toxic. It breaks down organic matter with every use, without harsh chemicals, hazardous substance handling, or unpleasant odors.
Regulatory Compliance
Bio’Loo meets regulatory hygiene requirements for underground construction sites (French Labour Code, Article R.4228-1 et seq.) while minimizing the environmental impact of works carried out in sensitive areas.
Bio’Loo Benefits
Transfer Tank
The transfer tank allows waste to be transferred from the Bio’Loo main tank to an external tank, without having to move the toilet itself.
This reduces maintenance costs and improves site hygiene.
As an option, the transfer tank can be equipped with a portable electric pump to facilitate waste transfer.
