Choosing the right size food waste processing system (biodigester) depends primarily on the daily amount of food waste generated, the number of meals prepared, and the operating hours of your professional kitchen. Hotels, large restaurants, catering facilities, and hospitals typically require higher-capacity systems that can handle continuous loading during peak service periods.
Weigh the waste every day and make a record of it. Alternatively, weigh the waste food on Saturday, Monday, and Wednesday if you can’t weigh it every day for a week. Take an average. Also, the capacity of a machine is based on the duration of your working day. If you add the same amount of waste food at regular intervals over an 18-hour day, you will need a smaller machine than if you dispose of the same amount of waste food over an eight-hour day.
