Goal 6: Clean water and sanitation
Vacation home owners in the Global North. Households with no access to sewer systems and scarce water resources. Users interested in sustainability, resource reuse, and onsite waste management.
Mass produced in a toilet factory. Mainly the porcelain is manufactured in China, and the rest of components and installation of toilets are made in Sweden. Some components, to make a complete system, have to be purchased seperately by the user. In this way, the customer can adjust their system to their own preferences; such components are available from Wostman.
Ecodry is trademarked
The Ecodry toilets are bought directly by the user from retail stores or ordered online.
The toilet has been distributed world wide and featured in eco-projecs in Australia, South America, Africa, and more

The Ecodry urine diverting dry toilet is made of porcelain. It is 450 mm high, 395 mm wide and 580 mm deep. There is a premounted watertrap in the urinehole and a 75 mm long and 19 mm in diameter premounted urine hose. The waterpipe is stainless with a flexible R15 and 8 AA batteries are included and premounted to run the fan. The toilet seat is made from plastic.
The complementary Ecodry Box has a capacity of 100 liters. A barrel of 80 liters normally lasts about 3 months for a family of 4. Emptying of the ecodry box hence has to be done 1-4 times per year. A big garbage bag is suitable to place in the box. The urine can be mixed with water (25% urine and 75% water) and applied to plants as a fertilizer. The faeces are stored for about 3 months during which they are dried and when emptied the contents of the Ecodry box of 100 liters weighs 10-20 kg. The contents can then be moved to a composting unit for composting.
Further design specifications and explanations of functionality are found in this document.
The toilet is installed over a container and the urine hose is connected to a container for the urine. A 200 mm pipe connects the toilet with the faeces container. A fan reduces odour and makes the waste dry faster so that pathogens are reduced. If desired, water can be connected to the toilet so that a small flush can be made in the bowl. If not, a small cup of water can be applied now-and-then to reduce the risk of urine odour and crystallization of urine in the urine hose. Product schematics are found in this brochure.
The smaller components attached to the pedestal can normally be found in retail stores. An example of a piece that can break and is replacable by Wostman or a retailer is a solenoid valve in the back of the toilet.
The manufacturer states “remains fresh after many years of use”, “eco-friendly”, “odourless”, “maximal comfort and hygiene” and “easy and logical to use and install” as targets for their product.
All accessories and spare parts are CE certified which means that they meet standards regarding health, safety, functionality and environment.
There are no direct safety concerns regarding this product. The biggest risk is contamination with excreta when emptying containers.
The toilet can be complemented by the Ecodry box storage container for storage of the faeces. It is suitable to place a big garbage bag in the box. There are some components that the user has to procure to make the system complete and adapt it to his/her own preferences. These are containers for faeces and urine, a 200 mm drop pipe, a 50mm urine pipe, and ventilation pipes of minimum 75 mm in diameter.
Yes, the toilets are in accordance with regulations for the markets they are targeting.
The manufacturer cites eco-friendliness, user friendliness, odour removal, and appealing design as important criteria in their evaluation of the product.
There are currently no standards for low-flush and dry toilets hence there is no CE certification for the toilet. ISO is currently working on a proposal regarding the development of standards for “Sustainable non-sewered sanitation systems” in which this product would be included.
