Composting Toilets Review

Sun Mar composting toilets have the NSF standard 41 certification for composting toilets which is required by many regulatory bodies. They are cheaper to buy than incinerating toilets but are more expensive to than the urine diverting toilets or deep freeze dry toilets. Ongoing costs are electricity (on electric units) and composting additives. On electric composting toilets the power is used to run a fan to expel odours and to power a heating element to evaporate excess liquids. This means that there can be no liquid outlet from the electric Sun Mar composting toilets. The electricity usage of the electric composting toilet is higher than the urine diverting toilet but lower than the electric incinerating toilets. There are non electric versions of every Sun Mar composting toilet model available. There is a liquid overflow on the non electric (NE) composting toilets. After each bowel movement a scoop of compost sure (mulch/composting additive) must be added to the unit. How much of this is used depends on how often you use the composting toilet. Sun Mar microbe mix, which is a culture of aerobic bacteria, can also be added once a month to boost the composting activity. If the unit is in constant use compost needs to be removed from the toilet once every 3-6 months. In weekend or holiday home applications this may be as little as once per year. This compares favourably to the urine diverting toilet which needs to be emptied every 2-4 weeks, incinerating toilet 1 week; all based on constant use. The material that is removed from the Sun Mar composting toilet is finished compost which the NSF have certified as safe. The compost, like the ash from the incinerating toilet, can be used in the flower garden and needs no further follow up, unlike the deep freeze or the urine diverting toilet where the waste needs to be contained for 12-18 months (best practice) to break down. In terms of ‘eco credentials’ the Sun Mar composting toilet may be the best as there is no liquid outlet on electric models. The patented bio drum technology means that microbes break the waste down in the presence of air and moisture just like they would do in nature.

Urine Diverting Dry Toilets Review

The Separett urine diverting toilets have the lowest initial purchase price in the range. The only ongoing costs are the compostable bin liners and the electricity required to run the fan, which are both minimal. Unlike a composting toilet they do not require bulking agents (mulch). In terms of electricity usage the Separett urine diverting toilets are most economical (electric) units on the site. Unlike the Sun Mar composting toilet the Separett urine diverting toilets do not compost the waste in the unit itself. The urine is diverted outside to a soakaway so that the volume of waste collected is minimised. The solid waste is collected in the unit. The full bags are removed and must be placed in a composting bin for further 12-18 months (best practice) before it can be buried in the ground in the compostable bag. This is similar to the deep freeze dry toilet. In contrast, the once the material comes out of the Sun Mar composting toilet or Separett incinerating toilet, it is safe to be placed in the flower garden or under the bushes. In terms of “eco credentials” the urine diverting toilet is very good. It uses very little power and no additives are required. It must be noted however that the ease of disposal is the neither as pleasant as the composting toilet, where finished compost is removed, or the incinerating toilet, where sterile ash is removed. The urine diverting toilet will need to be emptied every 2-4 weeks which is less often that the incinerating toilet (1 week) or deep freeze toilet (2-3 days) and more frequently than the composting toilet ( 3-6 months) Also it must be noted that using this technology, urine is discharged into the ground outside the building so the unit does need a liquid outlet unlike the Sun Mar electric, Privetti deep freeze and incinerating toilet which do not have a liquid outlet.

Incinerating Toilets Review

The Separett incinerating toilets have the highest purchase price in the range of self contained units. Ongoing costs are electricity and bowl liners. The bowl liners must be used at every visit, and they are low cost. There are no additives required. Once a week the ash tray needs to be emptied, based on continuous use by 5 people. This is more frequent than the composting toilet (3-6 months) and urine diverting toilet (2-3 weeks). The finality of the incineration process and the ease of the ash disposal make the incinerating option the most like the old flush toilet from the user point of view. There is no ongoing biological process at work and after each cycle the unit does not contain any waste from the previous user. The ash can be placed in the bin or in the flower garden and needs no further follow up. There is no liquid outlet from the unit, like the Sun Mar electric composting and deep freeze toilets. There is an air outlet vent required like all of the types except the deep freeze toilet. Unisex waterless urinals are often used in conjunction with the incinerating toilet to save energy.

Deep Freeze Back-Up Toilets Review

See our full range of Deep Freeze Back-Up Toilets
The deep freeze toilet addresses the occasional need for an emergency toilet. It is more expensive than a urine diverting toilet but cheaper than the composting toilet or incinerating toilet. Since there is no air or liquid outlet there is no installation required. This unit is ready to go in 30 mins and therefore can be used in situations when normal toilet fails occasionally. There is no composting happening in the unit and there is a 6 month composting follow up like the urine diverting toilet except that here you also have frozen urine to deal with. The unit is easy to use but the follow up is arguably the most hassle in the range as there is liquid and solid to deal with. The power usage is low and there are no additives required but it is not intended as a long term solution. There is no liquid or air vent outlet required.
