FAQs of our food composters

Our food composter BMD machine is made for composting food waste only. We are also responding to the need for digesting compostable packaging with the BMD+ so it can do more than only composting food waste. If your question is not in the FAQ, you can send us an email or contact us by phone. You will find our contact details by clicking the link below.

Aerobic digestion is a process of digestion by  micro organisms which remove odors. Compared to anaerobic digestion, which causes toxic gases and bad odors, it is a safer and more pleasant process. Instead, CO2 is produced as a natural cycle when waste food decomposes in our food composter. It is both environmentally friendly and safe. After all, our food composters emit natural CO2. 

NO, all of our products are meant to be environmentally friendly and all of our processes rely on environmentally friendly microbes and water. Microorganisms are extremely common and can be found all around us. Even microorganisms found in our products are not dangerous to humans unless they are consumed.
Furthermore, all of our products produce only water and CO2 as a result of the activation of microbes. It is completely green discarded food. All of these products are environmentally friendly and circulate naturally.

Putting in wastes not categorized as food waste such as shells, hard bones (from pork, beef, or lamb), fossil plastics, dishes, glass may lead to failure. 

No, the machines that are composting food waste have a mechanical door seal, which eliminates the possibility of leaking, as well as an automatic water/flush system, are available from the liquid food digester. Furthermore, our microbes have their own scents, allowing them to detect odor.
Furthermore, the breakdown is used to speed up the natural process so that no odor or smell is produced.
The fallen leaves from trees, for example, disintegrate in nature. There is no odor associated with this procedure. The food composters follow the same procedure. Our machine just accelerates this.

No, the process of food composting and breaking down bio-plastic and compostable packaging goes on 24/7.

Green bin or BMD machine?

See the difference

Do you also have a green bin that looks like this? Knowing you have to wait another 4 days before the truck comes to pick up the food waste. Not even mentioning the task of cleaning the container and doing this week after week.
Let’s solve your food waste problem and create a hygienic way of getting rid of food waste. A future without the hassle of a smelly, dirty, fly-creating green bin. Welcome to the world of a BMD machine.

All food waste goes right down the drain there is no food left to remove ever.

There are load cells mounted on each corner of the digester. These weigh the total weight of the digester. On installation, the software calibrates itself so it knows the empty weight. From there, the software knows how much is in the food composter and how much is added each time.

Every day, weigh the waste and keep track of it. If you can’t weigh the waste food every day for a week, weigh it on Saturday, Monday, and Wednesday. Take the average. A machine’s capacity is also determined by the length of your working day. You’ll need a smaller machine if you add the same amount of waste food at regular intervals over an 18-hour day than if you dispose of the same amount of waste food over an eight-hour day.


The fresh waste food is mixed with the old waste food and the Powerzymes in the digester (microorganisms). The decomposition of discarded food mostly creates water, CO2, and heat. Small pieces of undigested food will reach the exit stream if waste food is chopped or crushed, raising TSS (total suspended solids) and BOD levels (biological oxygen demand). The digester’s motor is only used to combine, or slowly swirl, the waste. It only operates for a fraction of the time, reducing the amount of electricity used.


This water does no harm to the environment as it is released in accordance with the Waterworks standards. Our Korean Manufacturer produces products according to the recently established Collective Certification Standard in compliance with the provisions of the Sewerage Act. Since the Korea has first highest population density among countries belonging to OECD (Organization for Economic Cooperation and Development), the extent of regulation related to the environment is very strong including Waterworks standard which allows us to meet most of Waterworks laws from across the globe.


The amount of carbon dioxide released from the food waste disposer is much smaller than that released when incinerating and burying it in the land. As it emits a very small quantity of carbon dioxide as much as when people breathe, it is hard to say it is dangerous.


No. You add waste food at any time. The machine is constantly digesting the waste.


How it works

food waste into water

Our food composters digest all the food waste within 24 hours into liquid grey water. No need to hassle with solid compost. Just connecting our food composter to the existing sewage piping system and your worries about food waste are over.
