Dependable, low-maintenance fans are available and use very little power, and most structures can be modifi ed easily to use solar panels. In fact, a solar-powered composting toilet just may provide the ultimate eco-friendly restroom. Composting toilets are sized accord- ing to the anticipated usage. Toilets at remote areas of golf courses are generally used far less than restrooms in the clubhouse, so most courses only need a small unit, which produces less compost. Less compost is a good thing because, eventually, someone will need to remove the compost from the unit. The removal and disposal of com- post derived from human waste may be subject to state, county, or municipal regulations, and a good place to initiate inquiries is your local county sanitation department.

It’s a small price to pay for reducing the load on your waste stream.

As one person has remarked, flush toilets are the accepted social standard. The idea of collecting human excrement in a basement composting bin does not exactly square with the modern paradigm of gracious living. There is, however, more to the story. In what follows, we describe six composting toilet installations of varying types, currently installed for public use in locations in the United States, including three in California. We consider only those for institutional, industrial, municipal and commercial venues, i.e., those for which maintenance can be assured. We do not consider composting toilet installations for residential use. In our descriptions, we include comments by administrators, architects and users. As we shall see, every one of these six installations is positively viewed. We also include a section on frequently asked questions, including discussions of costs and possible legal barriers.

According to the adequate environmental management in Yanbian Korean Autonomous Prefecture (YKAP), northern China, this culture may be comfortable to the people of China, yet uncomfortable to the non-Chinese. We conducted a series of field surveys and individual interviews (Chinese n = 1000 and non-Chinese (foreign visitors) n = 100) on several aspects of the public squat toilet: structural properties, waste disposal methods, important factors, and overall satisfaction level. The significant factors in response to the public squat toilets were cleanliness, odor, toilet paper, temperature, soap, other facilities, and presence of cubicles. These factors should be the policy priorities of local government. In addition, 66.2% of Chinese and 91% of foreign visitors desired type E toilets (two full-height partition walls per cubicle, with a door). The results illustrate the nature of a sustainable and aesthetic approach to the culturally and environmentally sound management of various types of public squat toilet in YKAP. The government needs to focus on the future-oriented and excreta treatment management of the sustainable toilet culture for the residents of, and visitors to, YKAP.

  • 2 the Robo-Toilet Revolution the Actress and the Gorilla
    George, Rose, 2014, The Big Necessity: The Unmentionable World of Human Waste and Why It Matters (pp. 39-64). Henry Holt and Co.. Kindle Edition. 2 THE ROBO-TOILET REVOLUTION THE ACTRESS AND THE GORILLA The flush toilet is a curious object. It is the default method of excreta disposal in most of the industrialized, technologically advanced world. It was invented either five hundred or two thousand years ago, depending on opinion. Yet in its essential workings, this everyday banal object hasn’t changed much since Sir John Harington, godson of Queen Elizabeth I, thought his godmother might like something that flushed away her excreta, and devised the Ajax, a play on the Elizabethan word jakes, meaning privy. The greatest improvements to date were made in England in the later years of the eighteenth century and the early years of the next by the trio of Alexander Cumming (who invented a valve mechanism), Joseph Bramah (a Yorkshireman who improved on Cumming’s valve and made the best lavatories to be had for the next century), and Thomas Crapper (another Yorkshireman who did not invent the toilet but improved its parts). In engineering terms, the best invention was the siphonic flush, which pulls the water out of the bowl and into the pipe. For the user, the S-bend was the godsend, because the water that rested in the bend created a seal that prevented odor from emerging from the pipe. At the height of Victorian invention, when toilets were their most ornate and decorated with the prettiest pottery, patents for siphonic flushes, for example, were being requested at the rate of two dozen or so a year.

  • Adventures in an Outhouse
    Adventures in an Outhouse During the summer of 1940 Shirley Scott's family was living in a tent in Butterfield Canyon to be closer to where her dad was working in the mine. While they were living in the canyon the only bathroom that they had was an outhouse. One day Shirley's brother Max, who was five years old, was in the outhouse. He had his favorite toy car with him and was using the toilet seat as a racetrack. He was driving his car around the seat when he accidentally dropped it down the hole. Max really liked his car so he stuck his arm down the hole and tried to reach it but it was too far down. He couldn’t get it on his own so he asked Shirley to help him. Shirley was seven years old and was more than willing to do what she could to help her little brother. The solution that they came up with was to have Shirley hold onto Max’s legs and lower him down the hole so he could grab the car. What could be simpler? The plan was working out fine until Shirley lost her grip on Max’s legs and dropped him headfirst into the nasty stuff that you find at the bottom of an outhouse. The sides of the pit were dirt so Max couldn’t get a grip on anything and he started sinking. He hollered for Shirley to help him but she couldn’t bring herself to put her hand down the hole to rescue him.

It is the architectural space in which bodies are replenished, inspected, and culti- vated, and where one is left alone for private re- flection- to develop and affirm identity” - Koolhaas, 2014 Content Introduction 1 Abstract 2 Research Method 3 Nomenclature 4 Guiding Questions Theory 5-6 Public Toilet 7 Public 8 Private 9 Toilet Analysis 10 Introduction 11-12 Timeline 13 Definitions 14-24 London 25-31 Paris 32-38 New York 39 Conclusion 40-41 References Abstract A reflection of societal values, the public toilet is a politicized space that provides sanitation in the public realm. In addition to its role in sup- porting a basic human need through sanitation provision, the public toilet is also a space that provides solidarity in the face of congestion, a place where one develops and affirms identity [Koolhaas, 2014]. In the nineteenth century through the twen- ty-first century, the public toilet has shifted from an external urban condition to an interiorized urban issue. It once stood as a symbol of moder- nity in the congested streets of industrial cities, and progressed to be prominently featured in ac- cessibility debates.
