Food Digester

Opportunity

34 million tons of Food Waste generated in 2009 Less than 3% was recovered and recycled Food Waste is the single largest component, of the

remaining waste stream, being disposed of in landfills

Landfills serve as the largest source of atmospheric methane in the United States.

Methane is 26 times more potent than Co2 on GreenHouse Gas.

Anaerobic digestion of food waste, once disposed of in a landfill, creates the methane.

Organic Material

Material that has come from a once-living organism; is capable of decay, or the product of decay such as food waste.

Food Waste

Includes uneaten portions of meals as well as trimmings from food preparation activities in kitchens.

Primary function of BioGreen 360 :

Accelerate the natural decomposition process of organic waste

through the utilization of advanced proprietary microorganisms

while maintaining optimal levels of aeration, moisture and

temperature.

BioGreen360’s unique microorganisms safely

decompose organic waste at an accelerated

rate, without soil or groundwater contamination,

into a soil amendment that is 10% of its original

weight.

How it Works Totally self-contained, continual

feed,organic waste disposal system

Biologically converts solid food waste into compostable material

Accelerates the natural decomposition

process by maintaining optimal levels of

aeration, moisture and temperature

The Digester quickly decomposes organic waste including:

vegetables, fruits,meats, fish, poultry, breads, pastas,

solid dairy products as well as bones, shells, rinds, peels and skins

BioGreen 360 Digester

An inside look of the main hopper shows the auger paddles that mix the food waste and the aeration pellets as the micro- organisms breakdown the organic material.

BioGreen 360 Digester

A grinder effectively reduces, bulk items and small bones, into smaller pieces. This creates increased surface area, allowing the microbes to breakdown these items more quickly.

BioGreen 360 Digester

A green visual indicator light shows when the unit is operating.

The red light will illuminate if either the hopper or grinder door is left open. The red light also illuminates if the grinder jams or other service is needed.

BioGreen 360 Digester

A look inside an operating digester shows the microbial impact on the food waste. The food waste is subject to temperatures exceeding 280 degrees. Fahrenheit, effectively killing all pathogens, bacteria and even seeds. From first input of organics to the start of compostable material discharge takes approximately 3.5 hours.

BioGreen 360 Digester

The enzyme enhanced microbial technology is classified as BIO Safety Level 1 (determined safe for human and animal contact).

The end product has been reduced by 90% and can be considered a bio-sterile mass. It is 95% dry and can be stored for several months.

What Makes This a Better Choice

BioGreen 360 Digester– Does not consume any

fresh water or discharge grey water

– No plumbing required

– No TSS (Total Suspended solids) issue

– No regulatory issues

– Only requires once a year reseeding of microorganisms

Liquid Based Digesters– Consumes 150 to 500 gallons

of fresh water per day and discharges 225 to 750 gallons of grey water

– Required plumbing adds $7,000 - $10,000 to installation costs

– Possible TSS issue as a result of dirty or grey water discharge

– Local regulations often prohibit grey water discharge into the sanitary water system

– Need to be reseeded with microorganisms every 2-3 months

What Makes This a Better Choice

BioGreen 360 Digester

– You are able to load throughout the day without restrictions

– Automatic discharge of solid final product

– No rehydration issues with fungus, bacteria or odor

Dehydrating Digester

– Must be batch loaded -restricted from being fed throughout the day

– Does not automatically discharge and requires manual discharge of solid final product

– Upon rehydration may produce fungus, bacteria and odor

Frequently

Asked

Questions

Digester FAQsQ. How do I know if my product is safe for soil application? A. Based on standard food material input, the by-product has a slight acidic PH so we recommend you mix it with other compostable material before adding it to your lawn or garden. If you feel it necessary, a soil analysis will determine whether or not one will help the other. The end product will vary from site to site depending on what goes into it, so this step is important to maintaining a healthy soil.

Q. If I use the soil amendment in my garden, will seeds from what was processed grow? A. No, during the cycle, the waste is heated to 280 or more for several hours, killing all bacteria and plant seeds in the process.

Digester FAQs

Q. Are the units mobile? A. All units have casters for easy mobility.

Q. How should I use my end product? A. The end product can be used on the grounds of your

establishment, sent to a composting facility. Because the end product is 95% dry, it is stable and can be stored for months, when not exposed to rain or snow, with no ill effects.

Q. My end product seems a bit wet; what should I do?A. You may have overwhelmed the unit by putting a large

amount of liquid into the hopper. BioGreen 360 is not designed for processing of liquid waste. If this occurs, it will require a normal cycle for all liquid to be evaporated and the unit to generate a normal by-product.

Digester FAQsQ. Should I expect some sort of odor? A. BioGreen 360 is a low-odor device. It effectively manages odor through activated charcoal air filters and a plasma deodorizer. It may emit a slight cooking odor at times, but it is unlikely that you will find it offensive.

Q. How simple is the unit to operate? A. Easy as 1, 2, 3. Open the main hopper door, dump in the waste, close the door and walk away - that simple

Q. What is the difference between BioGreen 360 and other units on the market? A. BioGreen 360 consumes no fresh water and does not discharge any dirty water into sewer system. The only discharge from the unit is the sterile biomass and small amounts of condensate runoff from the condenser unit, which is safe to pour down the drain.

Digester FAQsQ. What type of material can go into a BioGreen 360? A. If it is from nature and fit for human consumption, your BioGreen 360 will love it.

Q. I work in a high-volume restaurant. Sometimes things get missed when sorting; will it hurt the machine? A. Making sure that silverware does not enter the machine is a must. Even a random piece here or there might damage the unit. Make sure that all inorganic materials are removed from wastes before loaded into the unit

Q. How should I install a unit? A. BioGreen 360 can provide installation thru our service provider network

Digester FAQs

Q. How often should the inside of the unit be cleaned? A. Typically there is no cleaning of the inner tank. Periodic buildup on the auger may need to be removed by a service technician

Q. Really, how full can I fill the unit? A. The fill should not exceed the auger blade height of the unit.

Q. My employees like to open the door on the unit during processing to see what’s going on is there anything wrong with doing this? A. No, however you will delay the process time for cycling the waste. When the door is opened for loading the unit stops. If the door is left open or opened unnecessarily, the unit is not running and will take longer to cycle.

Digester FAQsQ. What power requirements do I need? A. Units are 3 phase 220 volt. Please refer to BioGreen 360 specification sheet.

Q. What do the number displays mean and is there something I should be monitoring?A. The number displays are for monitoring temperatures and time. They are pre-set at the factory based on your requirements (waste stream) and should require no additional input. If the numbers on the display exceed the programmed set points, the unit will shut down.

Q. How much does it cost to operate BioGreen 360? A. We estimate an average of $285 a month for the BG-1500 model. This is based on a rate of 16 cents per KWH. This cost of kilowatt hours will vary from region to region.
