Marcel is Shit&Blossoms basic model. It was firstly designed for the big chamber systems where leakings over the separator is not problematic because it goes directly into the solid container. As our separators are plastic free and more hygienic solutions made for DIY toilets, designs and options of such are really vast. By the time it has proven in praxes that it is suitable in much more variations, designs and even in some industrial toilets, then just for classical compost rooms. That is why we like to call it Marcel the universal model. Because dry toilets are based on composting, they can accept kitchen waste. To be precise, anything that is organic and therefore, biodegradable, can be tossed away in the dry toilet. Think paper, banana peels, eggshells, and leftovers! a Note: FU – fresh urine, HU – hydrolyzed urine, RC – reaction conditions, TOC – total organic carbon. That’s why our separators are made from porcelain . We believe in using the best quality materials that are both eco-friendly and long-lasting.

Only the Separett Privy 501 divider inserts are slightly rounded at the front to disappear under the toilet seat. F. Li, J. Behrendt, K. Wichmann and R. Otterpohl, Water Sci. Technol., 2008, 57, 1901–1907 CrossRef CAS PubMed. This might explain why terms like shit and piss are swear words at best, frivolously flushed away in our “civilized” water toilets. But our hot take is this: They deserve more recognition than that, fart jokes and all. The most popular divider inserts for portable toilets, composting toilets and dry toilets on the market are currently:Urine hydrolysis has a significant impact on the FO process, which is influenced by pH and the enzyme urease. Engelhardt et al. 78 used hollow fiber, aquaporin-based membranes for NH 3 rejection and water recovery to improve the nitrogenous compound rejection, and pH control was also used. The results showed that the best pH for urea hydrolysis was 7.4, and by using urease-processing and pH adjustment, the TN rejection could reach 89% (with 75% water recovery) to 98% (with 25% water recovery), using 5 M NaCl as the DS. When using 5 M glucose as the DS, the NH 3 recovery ranged from 97% (with 50% water recovery) to 99% (with 25% water recovery). Following that, the performance of an Aquaporin Inside hollow fiber FO module (Sterlitech) used for urine volume reduction without DS for long-duration cave expeditions was tested, and a portable FO prototype was introduced, which was able to reduce the urine volume by approximately 75% and reject approximately 86% of the TN. 79 P.

It also builds very far into the depths. This means that a correspondingly shallow bottle or canister must be found. Or the toilet housing must be correspondingly high.

For any additional info on what is allowed to go into a liquid/solid container, consult our visual guide: At our earthship in Serbia, composting and toilets go hand in hand. What makes these toilets “dry” is the fact that they DO NOT use water for transportation or treatment of collected waste (more on that later). Shit and Blossoms workshop offers a colored versions in a limited edition because they are all unique and each one of them is painted by hand. Colors that we are using are ceramic pigments and glazes burned on a high temperature, waterproof and resistant on rinsing aid. Even the ones with textures are safe from scratching and washing. J.

What kind of separating insert do you have in use? What is important to you? Do you have any questions that are still unanswered here?
