1 Our nation’s Population Reached 300 Million on Oct. 17, 2007
There’s an increase in the total population of the nation of one person every 11 seconds. Each American makes about 4 pounds of garbage daily. The Environmental Protection Agency reports the United States produces approximately 219 million tons of garbage each year. 10/14/2019

2 Why Compost? Most people do not realize that there are real problems associated with placing organic waste, especially food waste, into landfills. Doesn’t nature look after this process naturally? It is generally held that because food waste is biodegradable no harm results from letting it decay naturally in landfills. Continuing to think this way means that we have landfills that are many times larger than they need to be, and they produce toxins rather than usable composted organic waste. Consider these alternatives for disposal of biodegradable wastes: Truck the waste to a landfill site to be mixed with other wastes and allowed to decay naturally. Separate biodegradable food waste from the rest of the waste stream and compost it locally.

3 Food waste occupies most of the space in landfills
Allowing organic waste to decay in landfills has a negative impact both environmentally and economicaly, and has quite different outcomes from using a local composter. Simply separating out biodegradable waste from the other waste to compost naturally would cause problems with odours and flies, and would not greatly reduce the amount of space needed. Natural decomposition also takes a long time. The biogas or mixture of gases that is generated in a landfill by interacion of all of the waste products generally is made up of methane (CH4), carbon dioxide (CO2), and hydrogen sulphide (H2S) and is often contaminated, sometimes by heavy metals like mercury. By composting locally using machines designed for the purpose, the majority of biogas vented is composed of (CO2) and water vapour (H2O) with trace amounts of the other gases without heavy metal contamination. The end product is a rich fertilizer that can be used for gardening or for balancing soil composition and ajdusting its pH levels. It has also been used as fill to reduce runoffs and erosion.

4 There are several other positive economic consequences.
Reducing the amount of food waste placed into the waste stream lowers the cost of maintaining a landfill site. It will be smaller, less polluting and easier to maintain. Trucking costs for hauling the garbage to disposal sites are also greatly reduced. Some businesses and hotels have been able to save thousands of dollars a year in operating costs by adopting local on-site composting techniques for food wastes. “Reduce, recycle and reuse” is a popular catch phrase of the “go green” movement and local composting helps achieve all three objectives. By reducing the amount of food waste produced, and by composting food waste locally we reducing the amount off money spent each year on waste management. By recycling our food waste through local composting our world becomes greener. By reusing the final product as fertilizer or soil conditioner we complete the cycle, and contribute to a better world.

5 What Can Be Composted? The GreenGood composter is specifically designed to compost food waste, but it can also compost manure, animal feces and other organic waste. Category 1 Food Waste Cooked Raw Fish Yes Fish Bones Meat Meat Bones No Poultry Poultry Bones Vegetables Fruits Fruit & Vegetable Peels Pasta Rice Bread & Pastry Egg Shells Coffee Grinds Tea Bags Lobsters Lobster Shells Crabs Crab Shells Shrimps Shrimp Shells Mussels Mussel Shells Clams Clam Shells Oysters Oyster Shells Category 2 Manure & Feces Yes No Hog - Cattle Horse Dog Category 3 Packaging & Yard Waste Yes No Yard Trimmings - Compost-able Packaging Paper & Paper Board Paper Napkin Category 4 Other Yes No Other waste materials -

6 Frequently Asked Questions
How safe is the compost produced by the machine? Our machines were tested by OWS and in their study they concluded that good hygiene material is obtained from our composting machines. What happens to the food waste in the GreenGood composter, and how long does it take to compost? The process reduces the volume of waste by 95% by evaporating water and discharging carbon dioxide gas. The remaining 5% is turned into compost. It takes from 12 to 24 hours for food waste to be composted. How do I optimize the performance of the composter? The composter performs best when different food waste types are mixed together. It performs less well on food waste of a single type such as only vegetable waste, or only bread and pastry waste. How does composting cooked food waste compare with composting raw waste? Typically, the composting machine processes cooked food much faster in 10 to 12 hours to complete the cycle. The cycle time will be longer for raw food waste such as eggshell, meat, poultry, fish and crustacean. The rule of thumb is the more raw contents you have in the food waste the longer the cycle takes to compost, especially if the raw contents are red and poultry meats. The compost derived from food waste with both raw and cooked contents is highly recommended for use as fertilizer How should the compost be used? After removing the compost from the unit, allow it to sit for a period of 3 to 4 weeks before using it as fertilizer. The recommended ratio for application is to mix ten parts of soil to one part of compost fertilizer. Can I use the same machine to compost food waste, and other sources like manure or animal feces? Yes, but be aware that any compost intended for use as fertilizer from non-food sources like animal feces or manure should be lab-tested first for absence of e-coli and salmonella bacteria. Consider using a separate GreenGood Composter for non-food composting if this presents a problem. What happens if only allowable Category 3 items are put into the composter? The composting cycle will take much more time to complete, perhaps up to several weeks. What are the “other” waste materials that should not be put into the composter? Plastics, metals, construction waste, textiles and wood in the form of toothpicks or chopsticks.
