Frequently Asked Questions

How much food waste does a restaurant need to generate to justify a dehydrator?+
A food waste dehydrator becomes cost-effective at roughly 200-300kg of food waste per week — equivalent to a large restaurant or small hotel. At this volume, collection costs of $300-500/month exceed the dehydrator rental of $250-400/month, plus you avoid collection entirely. Restaurants generating under 100kg/week (most small-medium venues) are better served by collection.
What does a food waste dehydrator produce?+
Dehydrators heat food waste to 80-100 degrees Celsius, evaporating moisture and reducing volume by up to 90%. The dry output resembles coarse granules or powder. It can be used as a soil amendment (not technically compost, as it's not biologically broken down), animal feed supplement (check regulations), or disposed of in general waste at greatly reduced volume and weight.
How much power does a food waste dehydrator use?+
Small dehydrators (processing 20-50kg/day) use 3-5kW of power on a standard single-phase supply, costing approximately $5-10/day in electricity. Larger units (100-500kg/day) require three-phase power and cost $15-40/day to run. Factor energy costs into your comparison — they can add $150-1,200/month to the operating cost.
Do food waste dehydrators create any odour or noise?+
Modern dehydrators have carbon filters that minimise odour, but some food types (fish, onions, dairy) can produce noticeable smells during processing. Noise levels are typically 50-65 dB — equivalent to a dishwasher. Both factors mean dehydrators should be placed in well-ventilated areas away from dining spaces and neighbouring businesses.
Is the output from a food waste dehydrator classified as compost?+
No. The dehydrated output is not composted — it's dried food waste. To be classified as compost under Australian standards (AS 4454), material must undergo biological decomposition. The output can be used as a soil amendment on-site, but if you want to give it away or sell it, it may need to comply with EPA guidelines for waste-derived materials. Check with your local EPA office.
