How our bioplastic food composters work

If you’re looking for a sustainable solution for your business, consider BMD Food Composters. Food composters can help you deal with food waste and compostable packaging, saving you money while making a positive impact on the environment. Our food composters use the natural breakdown of food waste by microbes in an oxygenated environment to break down food waste into carbon dioxide and water. 

This process replicates the human digestive process and produces a liquid effluent that can be deposited into current sewer systems or used as irrigation and fertilizer on-site. By treating your food waste and compostable packaging waste on-site, you can eliminate the need for waste to be transported to a landfill. Our BMD machines accelerate the degradation of organic waste by microorganisms, which is much faster than in landfills and is environmentally friendly. If food waste is a problem you’re already dealing with, food composters may be a simple answer you’ve yet to discover. A food digester uses the natural breakdown of food waste by microbes in an aerobic enzymatic breakdown process. 

Food waste digestion aids in the management of organic waste where it is created. Choosing to treat your food can help you address some of the major food waste challenges, such as eliminating the need for waste to be trucked to a landfill.

Microorganisms efficiently degrade organic waste, and they do it significantly faster in our BMD machines than in breakdown in landfills, which are destructive to the environment.

food composters started 70 years ago

Since the early 1950s, researchers have been studying aerobic digestion, and since the 1980s, many sewage treatment plants have used a combination of aerobic and anaerobic digestion. Modern food composters are now an accessible, sustainable, and a cost-effective solution for organic food waste disposal., Many facilities in the hospitality industry, have already discovered aerobic digestion, thanks to advances in research and technology over the last few decades.


Aerobic digestion, should not be confused with anaerobic digestion. Anaerobic digestion, while similar to aerobic digestion, does not require oxygen and is thus slower and less effective. Anaerobic digestion also produces methane, a harmful greenhouse gas that we want to avoid, as well as hydrogen sulfide, also known as “rotten egg gas.” To cope with food waste, food waste digesters use aerobic digestion.

1. Fill the food composters with organic food waste.
2. Incorporate microbial blends
3. To aid aerobic digestion, the digestor oxygenates food waste.
4. Food waste is digested and broken down into tiny bits by the biochips added. Then liquid is generated by that process, before being discharged as wastewater.
5. The wastewater is filtered through a screen and grease arrestor before being discharged into the existing plumbing system.

Decomposition time

Our BMD food composters can be used 24/7. Food waste can be added during the day. This prevents overloading the food digester when all the food waste from one day is added all at once. There are a lot of reasons why one food waste type digests more rapidly than another one. Most of the food waste will digest within 24 hours.

For compostable packaging and bioplastic, our trials suggest that there is also a big difference in composting time. When the material is thicker and larger, it will most likely take longer to digest PLA and other compostable packaging in our BMD+ Food Composters than it does to compost food waste in our BMD.

Plant-based Biochips

Our goal was to create a food composter capable of digesting both food waste and compostable packaging. To achieve this, we developed an additional appliance that could be integrated with our BMD machine. Many companies have shifted towards plant-based packaging, such as PLA bottles, cups, and cutlery, to move away from the use of fossil plastic. Fossil plastic generates microplastics that can cause health issues for animals and humans when it enters the environment.

To address this issue, we developed a better solution for biochips. Most other food composters use biochips made from fossil plastic, which can release microplastics into the greywater and waste stream when replaced and discarded in landfills or incineration. Our BMD food composters, on the other hand, use 100% plant-based biochips, eliminating the potential for microplastics and ensuring a sustainable waste management solution.

Our food composters

Our food compostes operate 24/7 with no odor or noise. They significantly reduce the cost to dispose of and manage waste food and eliminate smells, mess, and pests from your trash bins. By installing the BMD Food Digester, you are reducing the amount of space and energy needed to remove the unwanted food scraps from your facility. It puts collecting, transporting, or piling up food waste in a landfill.

At the same time, it will reduce your costs, and give your organization on-site control over a large portion of the total waste stream.
