Review: Die happypo Po-Dusche

Waschen statt nur Wischen. Was sich auf den ersten Blick etwas seltsam anhört, macht eigentlich schon sehr viel Sinn: Statt nur mit trockenem Toilettenpapier oder Feuchttüchern, reinigen wir uns den Hintern fortan primär mit einem Wasserstrahl und wischen dann nochmal trocken.

Die Mehrheit der Weltbevölkerung vertraut auf Wasser wenn es um die sog. “feuchte Analreinigung” geht – und das ist gar nicht so falsch. Sauberes Wasser reinigt den Körper sehr viel besser als trockenes Papier. Oder würdet Ihr Euch statt zu duschen auch nur mit Papier abreiben? Eben.  Continue reading “Review: Die happypo Po-Dusche”

nowato Toiletten Frankfurt

Die Frankfurter Firma nowato (no water toilets) bietet seit einigen Jahren mobile Kompost- und Trockentoiletten an, die ganz ohne Wasserspülung und Chemie auskommen. Dadurch eignen sie sich auch für die Orte, an denen ein Wasser- und Abwasseranschluss nicht gegeben oder möglich ist.  Das komplette Design des Toilettenhäuschens unterscheidet sich von dem herkömmlicher Event-Toiletten und hinterlässt einen sehr positiven Eindruck. Zeit also, mit den beiden Gründerinnen von nowato ein Gespräch zu führen und das Label in Frankfurt etwas bekannter zu machen:

Hallo Elisabeth und Severine, wer seid Ihr, wie kamt Ihr seinerzeit auf die Idee mit diesen Toiletten und was war Eure Vorgeschichte?

Meine Schwester Severine und ich wollten uns selbstständig machen und wir suchten nach einer Geschäftsidee, die uns weg von dem PC bringt (wir waren beide vorher in der IT-Branche tätig) und in der wir für uns einen Sinn finden. Und das haben wir bei den Kompost- und Trockentoiletten gefunden. Entdeckt haben wir sie auf Reisen und in Frankreich. Obwohl das Produkt an sich nicht neu ist, kann man noch viel weiterentwickeln, verbessern, optimieren und natürlich bekannt machen. Komposttoiletten überzeugen durch die Einfachheit des Prinzips, den guten Geruch und durch ihr Erscheinungsbild. Unsere Kunden sind völlig begeistert. Und wir freuen uns über die sehr gute Resonanz der Produkte und unserer Dienstleistung.

Nur das mit dem weg vom PC hat nicht ganz geklappt…

Pros and Cons of sustainable portable toilets in Germany

The following post was written by guest blogger Kevin Kuhn of NonWaterSanitation.de:

In this article, I´d like to talk about one topic which is not very common in the field of sanitation. I am talking about rentals for portable toilets for any kind of events, construction sites, or festivals, but even for parks, beaches, e.t.c. for the long-term.

Why is it worth talking about it?
The sanitary situation on the sector for portable toilets is catastrophic. Sometimes it is worse than the situation in third world countries! At the moment people leave their homes and go to a crowded place, and it is nearly impossible to find proper sanitary installations. Most of the time they have a disgusting odour, they are stuffed with waste and the dirt doesn´t even let you think about sitting on it. If you know one of these plastic toilets, you will definitely recognize your experience with distaste. The worst situation appears on festivals for 2-5 days. During these events, people don´t have any possibility to enjoy a normal toilet. I have heard about people getting communicable diseases and constipation after such a weekend. So let me ask you, is that a situation which we can except in a far developed society like ours?

Following this main problem, there are also the questions of sustainability in sanitation. The supply of cabins made out of plastic, does not seem to be a good solution for solving greater problems like declining resources of oil and climate change. They are very energy- and resource intensive in their production and cleaning processes. Special trucks are needed to collect the waste, to transport these bulky cabins and to clean the toilets via high-pressured water. A last point to be mentioned is that waste-water treatment is really struggling with the waste in those toilets through tampons or other sanitary products. Apart from that, the nutrients of urine and feaces are lost while treated in those facilities. This should let us also think about the externalities of supplying sanitation facilities.

There is a green solution
To solve the problems we are tackling, we have to rethink the production of toilet cabins, the treatment of the waste, and mainly the service around toilets.

Sustainable production of toilets: The current dominating plastic toilets have two advantages: they are light and they are easy to produce in masses. But using local wood instead as the main component makes it easier to disassembly them. The toilets are also light and it is a renewable resource.

The treatment of human waste: The treatment will be done through composting the collected material, in the same way it is done in private gardens or Ecosan projects. Sustainable mobile toilets are composting toilets. This means that there is a barrel under the toilet seat which can easily be removed and exchanged. Also there is no energy and no water used to convert human waste into valuable humus.

Service around toilets: It starts with using grid material to avoid any kind of distaste and odour. To achieve this, chipped wood will be used. This can easily absorb the moisture and is biodegradable. Also there is a need to raise awareness for sanitation, which can be achieved by having an employee who supervises the toilets and promotes sustainable sanitation, or through special offers like Tippy-Taps or music.

The revolution already started! But just began in central Europe.

If you do a quick Google search, you will find some worldwide festivals which are trying to have a share of 100% from sustainable toilets. Some examples include the BOOM festival in Portugal, Natural Event in Australia, and many smaller suppliers in England and France. Their goal is to make sanitation fascinating. Thus they have colourful toilets, easy-going staff, or even a DJ. There are actually people dancing in front of toilets. Some of the suppliers are taking a pay-per-use fee, some get paid by the organiser. But what they all have in common is the problem of logistics. Because serving toilets and treating faecal matter of 1000s of people needs a master plan. Mostly there are waste containers used, because the wheels lighten the transport. Afterwards it will be collected in larger containers and transported to a local farmer or any other composting site.

That works well for festivals, where mostly young people go to and most of the festivals in Europe try to start building their own composting toilets. But how is the market for one-day events like a street party, a family party, or construction sites so far? For that kind of service there is still no clear answer. This is mainly because organisers don´t know about this alternative. Another reason is the higher price that is still needed; like in any other breakthrough technology, new competitors have financial disadvantages.

In Germany and Switzerland, a few smaller companies were established in the last two years. EcoToi is working in the area of Berlin, nowato in Frankfurt/Main, Goldeimer in Northern Germany and Kompotoi in Switzerland. Thus, they are spatially separated and can´t compete with each other. But every one of the companies has the same problems:

  • costly and laborious production of toilets
  • a small budget and mostly depending on sponsorships
  • a small staff
  • high transportation cost
  • suppliers for conventional portable toilets canoffer lower prices
  • they just have a small stock on toilets (2-8), which is not sufficient for most organisers
  • lack of knowledge about alternative portable toilets

One advantage all the teams have right now is that some social groups are willing to pay a higher price for a green product. Almost every of these firms want to donate their gains to sanitation projects. This kind of corporate sustainable responsibility is well appreciated by the costumers, though the gains are too small until now, to create a noteworthy impact. The fact that these toilets offer more comfort is very important for those users. Also, there is still some uncertainty about the law situation for recycling of human waste. Until now mostly farmers and biogas plants take care of it with their own responsibility. But still the major target for the future will be to be financially independent and to up-scale the business and compete with conventional suppliers.

What do you think about the way to make sustainable portable toilets well-known as a better alternative? Should there be room for this kind of innovation?

Urilift

Public toilets are missing in most countries – even in 2009 we still lack decent, clean & affordable public toilets in most places and it’s still only a few companies that are active in this sector.

One reason for coming up with this blog certainly was the lack of such public facilities, and it is projects like the Kenyan Ikotoilet that my main interest is focussed on (~ seeing “sanitation as a business”, not only as an unpaid for, unappreciated public service). While we will blog about Ikotoilets in the coming days (will be published on AfriGadget.com first), let me introduce you to a Dutch company called Urilift that produces so-called “pop-up urinals”:

urilift-4bdefurilift-1bdefUrilift: “The Urilift is placed where it is needed: at hot spots in entertainment districts, for instance. Three people can use the urinals in the attractively styled stainless steel cylinder at the same time without seeing or being bothered by each other. The Urilift is only above ground when it is needed. For the rest of the time, it is completely hidden underground.” And there’s one interesting detail: “The Urilift is connected to the water mains but can also be supplied with a water tank, or without water. The water tank operates on an ecosystem that is filled automatically with rainwater.”

stap4UriGienic… is similar to the Urilift, but with a toilet seat: “The unique UriGenic toilet pan, a ‘wok’ with a suspended toilet seat, is the perfect solution for men and women. Since the toilet seat returns automatically to a vertical position after use, the unit can also be used by men as a urinal. Splashes on the seat are therefore a thing of the past. Naturally the unit is completely lockable so that the user can enjoy total privacy. It is also practical to use and exceptionally hygienic.”


nachtUriVisable “…can not be hidden below ground level. For this reason the UriVisable is extremely suitable for locations where permanent placement does not cause any objections and where, taking into account the pattern needed, a urinal is required 24 hours a day.”



There are also videos available online on the website of Urilift as well as on YouTube which demonstrate how such a public toilet pops up on the street and how they submerge e.g. during daytime.

Now, being connected to the mains sewer means that these toilet system will probably only work in cities where the sewage system already exists and that all valuable nutrients contained within the waste streams are actually wasted. The interesting questions are:

  • How much does such an installation cost and what kind of permits are required from the City Council?
  • Are there any subsidies from the local City Council to promote such public toilets (which, to my understanding, would have to be paid for by bar/restaurant owners)?
  • Would a waterless urinal also work in such an environment?
  • Would it make sense to turn a UriLift urinal into a waterless urinal in order to save on flushing water and to collect the urine for use in urban agriculture projects (e.g. allotment gardens within the city)?

UriLift sure is an interesting technology and the right step forward. I’d love to have one of those toilets right here in Frankfurt/M., btw.
