The environmental and lifestyle benefits of putting it down the sink.
Unlike popular belief, food waste disposal units are an efficient, economical, environmentally friendly and hygienic way to dispose of foodwaste. The following points illustrate our point:
Water Usage
- Food waste disposers are NOT water guzzlers. Unlike other household appliances such as dishwashers and washing machines, food waste disposal units use very little water
- An independent study determined that food waste disposers use less than 6 Litres a day. This is a fraction of the daily average household water consuption
- In fact the average water consumption of an food waste disposer is the equivalent to 0.1 washes of a 4.5 star washing machine
- A 4 minute shower uses as much as an food waste disposer would in 11 days
Greenhouse Emissions from Food Waste Disposer Operation
- The household average daily power consumption of an food waste disposers is equivalent to the operation of an 60W light globe for 9.7 minutes or an LCD TV for three minutes
- A recent life cycle analysis showed an food waste disposers combined with a waste treatment plan was the cheapest option for disposing of food scraps and gave off the lowest emissions
- Using an food waste disposers to dispose of food scraps gives off less greenhouse gases than putting the scraps in landfill
Impact on Sewerage System
- A half-century of international studies indicate food waste disposers do not overload or place pressure on the sewerage system
- The greatest contribution to wastewater discharge from an average household is from the bath / shower (33%), followed by the toilet (31%) and laundry (23%). These are significantly greater than that from the average food waste disposer (1%)
- The connection of one household unit to the sewer system is equivalent to about 110 additional food waste disposer units
Composting
- Composting is not the only environmentally friendly method to dispose of food scraps
- Food waste disposers can complement the compost pile. Certain items including meat, fish, and dairy products should not be composted due to health risks, but can be put down a disposer.
- Almost all food waste can be put down a disposal unit including bones, prawn and egg shells
Other Information
