1. food waste digester Q amp A s Waste 20 Model W20 180 What does it do Waste20 rapidly digests soft food waste and converts it into grey water which runs away to drain simply throw in the food and walk away The process is called aerobic digestion and a naturally occurring blend of microorganisms help with this process What can put in the machine The machine will take soft organic food waste such as fruit vegetables cooked and uncooked meat fish and so on The general rule is that if a human can eat the food the Waste20 will process the food The machine and the microorganisms are designed to process a wide range of food waste types in mixed quantities If your operation disposes of a large quantity of one type of food waste contact Tony Team for advice before operating the machine What can t I put in the machine The machine cannot process anything that is not soft organic food waste and cannot be easily broken down such as bones seeds and stones flower stems packaging general waste cutlery crockery etc The general rule is that if a human cannot eat the product then Waste20 cannot process the product This is important because placing the wrong products into the machine could cause damage and could void the warranty What stays out inorganic or fibrous materials such as Bones wrappers packaging styrofoam plastics dishes crockery or cutlery napkins serviettes flower stems oil fats greas2. 1 2 in at approx 425mm AFFL Only use swept waste fittings with a maximum of 4 fittings between the machine and the soil amp vent or floor drain Ensure connection is to foul water drain Do not fit trap Appliance is trapped internally Do not use compression push fit short or close fittings Installation must be carried out in accordance with local authority requirements Water supplies require appropriate back flow prevention Minimum recommended wall gap to rear of appliance 90mm Allow a reasonable gap for a service engineer to also access the side panels Installation should be in a well ventilated area What if the red SERVICE light flashes The SERVICE light will flash and the alarm will sound if the machine shaft becomes jammed If this happens open the machine lid and remove the cause of the jam Rubber gloves should be worn for this operation The machine shaft will not run until the lid has been closed What if there is a power cut or someone turns off the power to the machine or someone presses the emergency knock off button Waste20 will not automatically restart Once the power is restored follow the procedure 1 Turn the isolator on the front of the machine to the ON position 2 Ensure the emergency knock off switch is pulled out 3 Press the green RESTART button on the control panel The machine will now restart NOTE The WAIT light will illuminate and the lid will remain locked for 20
3. The water usage is pretty consistent over the day however there will be a slight increase during operational hours as this is when the lid is being opened So if 600litres per day is the maximum draw it will use about 25litres per hour on average This will increase slightly during operation and be less than that during the night Will methane gas build up in the machine This is not a cause for concern Only a trace amount of methane is produced which is flushed away down the drain What happens to the food waste inside the Waste20 Why not derive energy from the waste Through an aerobic process the machine contains enzymes that digest the food and starts the breakdown of fats and greases resulting in carbon dioxide and water About 75 of food waste is water anyway so all the water going back into the sewer system is a good thing A local company could take the food away and use the same aerobic process to reduce the food to biomass to burn for energy but heavy wet food waste is very energy intensive to dry out so why incur the extra costs Alternatively a local company could use anaerobic digestion AD to convert the wet food into methane for energy production but some waste water companies including Thames Water already use this process themselves So it s possible the grey water from the Waste20 could already be feeding into an energy producing process But in these commendable schemes to derive energy from food waste not only are t

8. he processes energy intensive but the food waste still requires collection from site using fuel to get it to its factory which would almost certainly use electricity in the process With the Waste20 all the food waste disposal is done right next to where the food was prepared Although there is still some biological content in the water output this is very much lower than if the food had been mechanically chopped up macerated or just flushed down the drain and after all the sewers are designed to take biological waste The important thing is that an operation is doing something to divert its food waste from landfill where it would form methane that could escape into the atmosphere which is far worse for the environment than carbon dioxide The manufacturer has been in close contact with Thames Water and other authorities to ensure due diligence Q amp A s DPV Revision 07 2011 Page 3 of 3 Product Overview Waste20 Model W20 180 PRODUCT INFORMATION Digests up to 180kgs of food waste over the course of 24 hrs no organic solids to manage Maximum performance and machine capacity is dependent on food temperature schedule of filling and types of food The resulting grey water effluent is safe for drains and sewer systems Output will vary according to volume and type of food waste added Only insert soft organic bio degradable food such as raw amp cooked meat fish vegetables fruit pasta noodles bread rice e
9. mpossible to gauge when the next load will be ready as it depends what kind of food waste went in Some food groups take longer to digest than others If the WAIT light comes on each time you top up with food waste then you are constantly overloading the machine and this could reduce the life span of the machine How do put food waste into the Waste20 Simply open the machine lid and pour the food waste through the hatch onto the woodchips inside then close the lid Why are there woodchips in the machine The woodchips are impregnated with specially blended microorganisms that break up the food waste The woodchips remain in the machine all of the time and only need topping up every 12 months Tony Team will contact you 12 months after your Waste20 has been installed to arrange for more woodchips to be delivered Can put refrigerated or frozen food waste into the Waste20 No Please allow for the food waste to come to room temperature before adding If very cold food waste is added it will change the conditions in the chamber and could kill the microorganisms that break up the food waste Is there any sludge or by product for me to get rid of No All of the soft organic food waste will be digested by the machine and will run away to drain as grey water Is there anything else need to do to keep the Waste20 machine running at it s best Yes You must ensure that there is always a box of Waste20 microorganism in
