Urine Diverting Composting Toilet Principles

Biolan urine diversion composting toilets are some of the most environmentally sustainable toilets available. The latest developments for urine diversion keep the liquid and solid waste separate so that sewage is never created in the Simplett toilet, therefore the Biolan toilet has none of the odour or waste handling issues that other alternative and composting toilets can have. The urine separation flap in the Biolan ECO toilet allows the to amount of urine mixed with the composting mass to be adjusted, so it’s not to wet or too dry.

Benefits of Biolan Composting for the environment

Biolan wants to contribute to a green and sustainable environment for present and future generations. A Biolan waterless toilets needs neither water to flush with, nor an expensive septic system, which is a great benefit to the environment. Moreover, the separation and composting process makes it possible to recycle the waste back to nature as an organic fertilizer. The benefit to you is a toilet solution without odour and at a very low operating cost.

Biolan conquers unpleasant odours

Until now, composting toilets meant unpleasant odours. When urine and feces are mixed together, the combination starts to ferment and create strong unpleasant odours that have to be vented through the roof. In urine diversion composting toilets, liquid and solid waste are routed separately which means the processes that cause unpleasant odours never occurs. Thanks to the low odour, the ventilation can be routed straight through the back wall, for a much simpler installation.  A wind turbine vent can also be added for even better odour removal.

Easy handling of the liquid waste

Thanks to this process of separation, it is easy and safe to handle the liquid waste. Depending on your situation you have a few choices for draining the urine; connect it to the grey water system, to a small gravel leaching bed, or to a holding tank. The Ejektortank is also an excellent choice when you wish to recycle the natural fertilizer from the urine to your flower garden. The tank connects to your hose and automatically mixes the urine with water to an 8 to 1 ratio for the perfect fertilizer.

Unlimited Capacity

When the urine, which accounts for about 85% of the volume, is drained to a leach pit the storage capacity greatly increases giving the toilet virtually unlimited capacity. The solid waste, feces and toilet paper, are routed into a container inside the toilet with a biodegradable liner. When the container is full it is removed for composting outside and a replacement container is installed in the toilet. Normal use by a family of four full time requires the container to be changed only every 3 or 5 weeks.

Solid Waste Handling

Thanks to this process of separation, it’s also easy and safe to handle the solid waste. Depending on your situation you have a few options for disposing of the solid waste. The container with dried solids and toilet paper, is easily lifted out and stored outdoors for 6 months, or the solid waste is simply emptied into a composter and mixed with other compostable materials.  These processes inactivate human pathogens, so that it can harmlessly decompose fully. The end product is an excellent organic fertilizer for your flowers or shrubs.  Other disposal options include dumping down an outhouse, incinerating in the Burn 900 Wood Fired Incinerator or just tossing on a camp fire.
