Frequently Asked Questions

Q1. How does the Sustainable Toilet Technology work?
A1. ECOLOO® is a 2-tier chamber whereby the upper chamber is where the human waste including urine is collected and treated by the bacteria whilst the lower chamber is where the organic fertilizer in a form of liquid is rendered to; ECOLOO® lower chamber is built with a special indicator and outlet for end users to collect the ready-to-use end product each time the lower chamber is full; ECOLOO® has only one hole and all the waste, including toilet paper, urine or wash water, will all go down naturally by the pull of gravity into the lower chamber.

ECOLOO® involves collecting toilet waste before it comes into contact with the environment, recycling it, treating it on site with special formulated bacteria, and then using the resulting treated fertilizer (liquid) for agricultural purposes. This creates a natural, unbroken cycle that replaces ‘waste disposal’ with ‘organic recycling’ or value added, safe-to-use fertilizer.

Q2. For whom is this technology a suitable alternative?
A2. Our technology is a suitable alternative for those wish to save water and save the environment. It is also perfect for those who have no access to water or infrastructure. Our eco toilet can also be used for other Applications.

Q3. What are the main advantages and benefits for using the ECOLOO® Technology?
A3. Our technology comes with the toilet, ergonomically designed, sustainable, odour free, water free, sewage free, chemical free, energy free, employs aerobic fermentation and biological processes, generates organic fertiliser which is odour free, bacteria free yet rich with nutrients, require less maintenance, easy to fit in any place, just plug and use, hygienic, aesthetically pleasing toilet, no discharge or unprocessed waste, no spillage of waste & can be in operation for decades.

Q4. What are the main disadvantages for using the ECOLOO® Technology?
A4. Anything chemical can kill our bacterial culture, so only eco friendly product can be used to clean our toilet such as our Eco Hygiene product series that is 100% organic, chemical free, alcohol free anti bacterial sanitizer.

Q5. What is the process for making toilet odour free? Is natural ventilation adequate for making the toilet odour free, especially in villages where access to electricity is a constraint?
A5. Other than our bacterial culture acting as an odour controller, our ventilation system is also another natural source for making the toilet odour free. Fixing a ventilation pipe with ventilation exhaust fan at a certain height is sufficient enough to replace electricity especially for rural areas where access to electricity is a constraint.

Q6. How does dry flush work?
A6. Our dry flush system is made available for users to spread the faecal matters to the sides to give more space for the bacterial culture to build its colony. Waterless toilets have existed since decades ago especially in the rural areas. Some collect the faecal matters to be composted into manure, some bury the faecal matters and move the toilet to another location, some let the faecal matters be eaten by the pigs. We provide the same environment as open defecation without smell but with dignity, privacy, security and at the same time convenient and safe for the environment. People can still use water to wash for hygiene purposes inside our waterless toilet and save the clean water from flushing.

Q7. What is the capacity of ECOLOO® lower chamber? What if the lower chamber of ECOLOO® is full?
A7. The lower chamber can hold up to 230 liter of concentrated liquid fertilizer. The liquid waste will be treated by our bacterial culture, which eventually will turn into organic fertilizer. However, each ECOLOO® user is encouraged to extract the liquid fertilizer once the lower chamber is full or when liquid fertilizer has overflown through the horizontal hole located at the front of lower chamber. To use the fertilizer, users must mix the concentrated liquid with 10 times of water.

Q8. What is the capacity of ECOLOO® upper chamber? What if the upper chamber of ECOLOO® is full?
A8. The upper chamber can hold up to 350 liters of solid waste. The solid waste will be treated by our bacteria culture, which eventually will turn into ashes, so it will never be full. However, each ECOLOO® user is encouraged to ‘dry flush’ using our dry flush system each time the solid waste grows high so that it is flattened and the bacteria can have bigger space and act faster in treating the waste.

Q9. How does ECOLOO® Technology treat the sewage?
A9. ECOLOO® has no sewage.

Q10. What manpower required to manage the system and how often?
A10. The only manpower required is to:
- clean around the toilet bowl for hygiene purposes daily (1 person a day).
- put the bacterial culture once a month (1 person a month)
- collect the fertiliser once a month (1 person a month). The one who put the bacterial culture and collect the fertilizer can be the same person.

Q11. How does urine and faecal matter is segregated?
A11.ECOLOO base is made of a 2-tier chamber: the upper chamber is where human waste including urine (not urine diversion system) is collected and treated by specially formulated bacterial culture whilst the lower chamber is where the organic fertilizer in liquid form is rendered to by gravity pull using no water to flush. The nitrification process that is built in the system converts the liquid waste into by product of value added fertilizer that is concentrated, very salty, odour free, pathogen free and yet full of nutrients within an hour or less. The salty environment makes it impossible for any bacteria or pathogen to survive in, a self disinfection solution.

Q12. What is retention time for complete digestion?
A12. Our process is aerobic and complete aerobic digestion takes from 3-7 days.

Q13. In some Countries, there is cultural issue handling toilet waste needs to be addressed. What would be mechanism for septage services (pumping the liquid fertilizers) especially in rural and school context?
A13. The monthly addition of bacterial culture and pumping of liquid fertiliser is as easy as 1-2-3. However, we also provide maintenance services at a minimal cost to our customers or donors. Upon delivery of our units, we will demonstrate to the villagers or schools on how to use the toilet and educate the people about the importance of water, sanitation and hygiene and saving the environment. We would give options to the customer whether to hire our maintenance service as part of the package or to maintain themselves and practise teamwork. If they choose to maintain themselves, then they must get the village or school head to appoint a leader from the community or school to handle the toilet with care.

Q14. The technology needs feeding bacterial culture regularly almost every month at cost? What would be the annual maintenance cost of feeding bacterial culture?
A14. The feeding frequency is once a month or once in 2-3 month, depending on the number of users per time. Annual maintenance cost of feeding bacterial culture is USD60-120.

Q15. Can the bacterial culture sustain the shock of usage of chemical cleansing agents?
A15. All bacterial culture cannot sustain the shock of usage of chemical cleansing agents, be it aerobic or anaerobic. Our technology requires eco friendly cleansing agent which is already in our product range.

Q16. What would be feeding frequency in case of usage of chemical cleansing agents?
A16. The feeding frequency is once or twice a month, depending on the number of users per time.

Q17. What is distribution network for the supply of bacterial culture?
A17. Each unit comes with 1 year supply of bacterial culture at an additional cost, and it will be made available upon request at USD60-120 per box.

Q18. What would be emptying frequency and cost of emptying?
A18. If the community choose to maintain the toilets themselves, then they must get the village or school head to appoint a leader from the community or school to handle the toilet with care, add the bacterial culture and collect the liquid fertiliser. They have a choice to either empty the liquid chamber and use the fertiliser or sell it to farmers at a cost and generate income.

Q19. The toilets based on bacterial degradation work for optimal loading. What is the optimal loading required for the ECOLOO® toilets?
A19. ECOLOO® is a dry toilet with no sewage. The liquid, urine and water, is treated & filtered and collected in the lower chamber that is continuously emptied. In this case, the upper chamber only consists of solid waste that is treated instantly by our bacterial culture and this gives more space for incoming solid waste. In average, a human being defecates around 0.4litre per day and 1 out of 5 toilet visitors are defecating whereas the rest of the visitors are only urinating. Therefore the loading for ECOLOO® is unlimited as only one person can defecate at a time with average of 5 minutes person giving the rate of 12-15 persons per unit per hour.

Q20. What will happen to ECOLOO® bacterial culture if we put chemical substances inside the chamber?
A20. In case chemical agent is accidentally dropped inside the toilet chamber, immediately pour a few liters of water inside the toilet chamber where the most chemical agent has dropped. Continue to use the toilet for a few days until feces cover the spot, and then add 1 sachet of bacteria accordingly. Start the process all over again by adding the bacterial culture once or twice a month.

Q21. How long does it take for ECOLOO® bacterial culture to treat the waste?
A21. The solid waste will be treated by our special formulated bacterial culture, which eventually will turn into ashes, killing all the pathogens. ECOLOO® bacterial culture takes about 4-7 days to process the solid waste, only 1-2 hours to process the liquid waste. Once the base is dry and out of liquid, the bacterial culture will stop working, build a shell and yet remain alive. The bacterial culture will start building its colony when the next urine or water is poured in. One chamber can fit in maximum 350 liters of solid waste and 1 liter of bacterial culture can treat the entire 350 liters of solid waste. The bacterial culture will only be poured in once the base is filled in with some waste so that the bacterial culture will have some food to grow on.

Q22. What if non-treatable objects are dropped inside the toilet?
A22. Stop using the toilet and let the bacterial culture continue to treat the waste for 2 weeks. If necessary, remove the toilet seat and pick the object up using scooping utensil.

Q23. Any maintenance recommendation?
A23. We do recommend the following:
1. Please use gloves in all of the above process to ensure that high level of hygiene and health are measured.
2. That the toilet bowl be always covered with the lid for health and safety measures. However, there will be no side effect should the bowl not be covered with the lid.
3. Make sure that all treated solid waste (ashes) is vacuumed out using proper industrial vacuum when it is full after some years or when removing foreign objects. Prior to that, remove the seat by releasing the screws.
4. The toilet seat can be cleaned when necessary using environmental friendly, non- chemical cleansing agent.
5. If chemical agent is used to clean the seat, make sure it does not spill inside the toilet chamber.
6. That liquid fertilizer that is extracted from the bottom chamber be left outside under the sun for further evaporation to ensure that the liquid fertilizer is 100% sterilized before selling/trading or using for your own organic agriculture.
7. Prior to using liquid fertilizer on agriculture, the liquid has to be mixed with 10 times of water as it consists of very salty self disinfection materials called nitrite and nitrate: organic fertilizer full of nutrients.

Q24. What financial advantages are there?
A24. With our solution you have extremely low running costs. Besides, no costs for transportation of waste, and no infrastructure needed.

Q25. Will liquid fertilizer be bought back by the agency and at what rate? What would be net gain for the toilet owner?
A25. There will be multiple gains for the toilet owner from maintaining the toilet to leasing the space for ads to trading the organic fertiliser with money or commodities, or using the fertilizer for their own organic agriculture. We can help facilitate with the buy back process between the toilet owners and farmers for the time being until we establish ourselves. The rate depends on the market price of the organic fertiliser in the market which is yet to be determined.

Q26. Do we need a permit for an installation of this system?
A26. As a rule you do not need a permit, but inform your local municipality.
