Raita EV envirotoilets have been developed in Finland. They are developed for indoor use (EV-IN) or for usein the smallhouse (EV-OUT) - they are odorless and hygienic.We have developed and manufactured envirotoilets since the 1970s. (TARA, EV). There are tens of thousands of our toilets in Finland, In Sweden and other European countries.EV toilets utilize the natural biodegradation process - organic matter and nutrients are biodegradaded with microbial activity - by composting.The natural composting process has been enhanced by EVstechnical solutions; by controlling humidity, air circulation, temperature and nutrient balance.EV toilets are easy to use, keep clean and empty.EV toilets use composting substance, which is dosed when using the toilet. Composting is effective - the result is 2-3% odorless compost of the waste after 8-10 weeks of composting.The toilet is easy to use and empty with the help ofchangeable compost van. By using two or more vansyou always empty fully composted compost.EV’s alternatives for handling the fluids (urine):1) SEP - urine separation2) ECOSEP - urinary separation of the stool, nutrientsused in the composting process.3) ECO - urine and its nutrients are used in compostingprocess.The liquid can be used as a fertilizer liquid (SEP) in its entirety. Or it can be used in composting.tp enhance the process and evaporating at the same time with in 95% to 100% of it’s amount.(ECOSEP, ECO) and the rest can be directed to a sewer system.
