A Biotank Africa plastic biodigester is one of the smartest, low-maintenance ways to manage human waste at home, it does not smell, there is no need for exhaust trucks, and there are no daily running costs.
But like any smart system, it depends on how you use it. Misuse can shorten its lifespan, cause blockages, or even kill the natural bacteria that do the work inside.
Here’s your go-to guide for what to do and what to avoid.
DO,s: What You Should Always Do
• Use It for Toilet Waste Only
Biotank’s plastic biodigesters are designed specifically for human waste and toilet water. Keep its use focused and simple.
• Use Biodegradable Toilet Paper
Toilet paper breaks down easily. Stick to normal or biodegradable tissue
• Flush With Water
Water is key to keeping waste moving and aiding digestion. Regular flushing supports healthy bacterial breakdown.
• Inspect Occasionally
Check that the outlet and soak away are flowing well. Look out for any overflow signs, bad smells, or slow drainage.
DON’Ts: What to Avoid at All Costs
• Don’t Flush Non-Biodegradables
No sanitary towels, diapers, condoms, wipes, or plastics—these don’t break down and will block your system.
• Don’t Use Harsh Chemicals or Bleach
Bleach, acid toilet cleaners, and antibacterial products will kill the good bacteria that power your biodigester.
• Don’t Pour Kitchen Waste or Oils into It
Biotank biodigesters are not kitchen digesters. No fats, grease, food particles, or soapy kitchen water unless your setup includes a grease trap.
• Don’t Add Farm Waste or Animal Manure
Those are for biogas digesters, not your household plastic toilet system. Biotank biodigesters are for toilet waste only.
• Don’t Overload the System
Avoid connecting more toilets or sinks than your system was designed for. Stick to the recommended usage.
