How our food composters work

As the imperative to enhance sustainability within businesses gains momentum, emerging technologies offer avenues for positive planetary impact and cost savings. BMD Food Composters stand as a tangible contribution to this endeavor.


For those contending with the challenge of food waste and compostable packaging, food composters might hold the key solution yet to be explored. Leveraging natural microbial processes, a food digester facilitates the decomposition of food waste. Through complete aerobic digestion, food waste is transformed into carbon dioxide and water within an oxygen-rich environment, all in a relatively short timeframe. Our food composters aim to replicate this procedure, converting food waste into liquid effluent that can be introduced into existing sewer systems or retained for potential use as irrigation or fertilizer within the vicinity of the core facility.


This process is governed by universal principles applicable to all living species, including humans. In fact, commercial aerobic digestion technology is sometimes referred to as a “mechanical stomach” due to its close resemblance to the human digestive process.

The digestion of food waste offers a practical means of managing organic waste at its source. Opting to process your food waste (and subsequently, compostable packaging waste on-site) can effectively address major challenges associated with food waste management, notably reducing the need for waste transportation to landfills.


Microorganisms adeptly facilitate the breakdown of organic waste, and this degradation transpires notably faster within our BMD machines compared to traditional landfill breakdown, which carries adverse environmental implications.

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 conflated with anaerobic digestion. While resembling aerobic digestion in some aspects, anaerobic digestion operates without the need for oxygen, resulting in slower and less efficient decomposition. Additionally, anaerobic digestion generates methane, a detrimental greenhouse gas, and hydrogen sulfide, commonly known as “rotten egg gas.” Food waste digesters employ aerobic digestion to address food waste challenges.

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.

Waste does not go to a landfill (no methane)

Reduces carbon footprint

Free of odors

Quiet operation

Eliminate flies, rodents, and smells

Plant-based Biochips

Biochips: We wanted to create a food composter that can digest food and compostable packaging. Designing an additional appliance that fits onto our BMD, was the kind of solution that made this dual use possible. The reason why most companies switch to plant-based packaging ( like PLA bottles, cups and cutlery) is that they want to step away from using fossil plastic. Fossil plastic creates microplastics in the environment which create numerous health issues for animals and people.
That’s why we needed to find a solution for a better biochips. Most other food composters are using biochips made from fossil plastic, that could release microplastics into the greywater and into our waste stream. When the Biochips are replaced by new ones. the old ones are often dumped into the garbage, and dumped into a landfill or incineration.

Our BMD supplies 100% plant-based biochips for our food composters.

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.
