Q1: Where are your microbes produced?
Q2: Can you tell us more about your “no water discharge” biodigester that does not require water drainage installation?
Ans: Aerobic digestion requires no additional water… no water discharge, so no additional piping. Hence no compliance issues with PUB sewage system.
Ans: During the process when the microbes degrade the food waste, water from the food waste are emitted and released to the environment through our digester. All this happens at low temperature below 40°C.
Ans: Analogy when you are doing exercise, water is dissipated as sweat from you skin with your body temperature above 30+°C.
Q3: How to we handle the fertiliser by-product after food waste composting?
2 types of customers here:
Ans: Some customers want to keep the fertiliser for their own planting or landscaping use.
Ans: Some customers don’t need the fertiliser, we will collect them during our routine servicing. After collection, most of them are recycled in our factory to produce microbes and some of them are use to sponsor community farming.
Q4: What happen if non-food waste items are disposed in the food waste digester ?
Ans: There is an agitator that rotates slowly to mix the food waste and microbes to degrade the food waste. If non-food waste items (eg plastics bags, paper, or large bones) are inside the digester, the microbes will not degrade them. They can be sieved out from the fertiliser and you could do a post segregation.
Q5: Are we able to track usage of user (individual) Data (information) for mandatory monthly food waste report?
Ans: The system is RFID enabled, where we can collect data from user(s) and facilitate submission of monthly food waste report.
Q6: How frequent do we need to top up microbes?
Ans: During initial installation of the system, we load 50% microbes. Say for 1 ton of food waste, we add 500kg of microbes.
Ans: Over 24 hours of composting, the 1 ton food waste are converted and reduced to 100 kg (10%) of fertiliser. The microbes will continue to work, and you can continue to load food waste into the system.
Ans: During routine servicing, (2-4 weeks depending on capacity utilization and dampness of food waste loaded), fertilizer are harvested, and we top up with about 20% microbes.
Q7: The digester seems huge, is there a more compact model where space is a problem?
Ans: Our digester sizes are compact by design and it ranges from the retail capacities at 2-5kg, commercial capacities at 20-100kg and industrial capacities at 300-2000kg. Depending on how much food waste is produced we will recommend it after doing a food waste audit.
Do contact us for a site survey to get the digester that is fitting to your facilities’ needs.
Q8: How do you manage the smell from the waste digester? Is the digester installed in any of the healthcare environment?
Ans: Our proprietary microbes have the capability to break down food waste in around 24 hours, thereby reducing food waste from generating the bad odour. Our design of biodigester seals also keep odour internally while the microbes degrade the food waste.
Yes. our digester is installed in Khoo Teck Puat Hospital.
Q9: Is the food waste digester able to accept all kinds of segregated food waste including post cooked food with oil?
Ans: Our proprietary microbes can accept food waste that has high water content like fruits and vegetables. Cooked food with oil can be treated but not in large amount. Too much oil will reduce the performance of the microbes.
