Sludge is not produced, just humus. 

No smell, no pathogens, just an easily handled soil conditioner

Avoid septic tanks, DEWATS and pits, these produce nasty sludge

Aerobic treatment

This means no methane emissions.

Avoid DEWATS and septic tanks, these produce greenhouse gas emissions and pollute our environment. Aerobic treatment is fast and smell free.

Self-maintaining treatment solution

The worms do all the maintenance work and keep the biological filter in great condition, while micro-organisms gobble up the pathogens
