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 and/or compostable packaging 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.

Full aerobic digestion breaks down food waste into carbon dioxide and water in a relatively short amount of time in an oxygenated environment. Our food composters try to replicate this process by turning food waste into a liquid effluent that can be deposited into current sewer systems – or stored to use as irrigation and/or fertilizer in the surrounds of the main facility.

All living species, including our bodies, follow the same laws that control this process. In fact, commercial aerobic digestion technology is sometimes referred to as a “mechanical stomach” since it closely resembles the human digestive process.
Food waste digestion aids in the management of organic waste where it is created. Choosing to treat your food (and later on, the compostable packaging waste on-site) 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.

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.

Bio-plastic - Food composters
for PLA PRODUCTS

Polylactic acid, also known as poly(lactic acid) pla, or polylactide is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world).

Biodegradable polymers such as PLA are designed to resist a number of environmental factors during use but to be biodegradable under disposal conditions.

The biodegradation of polylactide (PLA) was studied at different elevated temperatures in both aerobic and anaerobic, aquatic, and solid-state conditions. In the aerobic aquatic headspace test, the mineralization of PLA was very slow at room temperature, but faster under thermophilic conditions. The clear effect of temperature on the biodegradability of PLA in the aquatic tests indicates that its polymer structure has to be hydrolyzed before microorganisms can utilize it as a nutrient source.

The results of these studies demonstrate that PLA is biodegradable in both aerobic and anaerobic thermophilic conditions. The temperature was shown to be the major factor regulating the biodegradation behavior of PLA.

In thermophilic conditions, anaerobic biodegradation of PLA was even faster than biodegradation in aerobic conditions, probably due to lactic acid being a more favorable substrate for anaerobic than aerobic microorganisms.

OUR Proprietory Enzymes and BioChips:
In many countries, it’s not allowed to put compostable packaging (PLA-PHA etcetera) into the existing industrial composting waste stream. Most of the compostable packaging products are designed to compost in facilities like this, but still, they are not allowed to be processed in an industrial composting facility. Our goal is to help you solve this problem and give the companies using compostable packaging a positive alternative.

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.
