Food waste can account for around 20% of household rubbish and the cost of disposing this waste mounts up, not just financially but also ecologically with limited landfill space and the costs of rubbish collection. Waste Disposal is a growing issue in Britain and waste disposal units are becoming more and more popular. Some local councils are even starting to encourage the use of waste disposal units in homes to help reduce the pressure on landfills and rubbish collection. InSinkErator invented the first waste disposal units in 1927 and have been producing quality waste disposal units ever since. Mounted beneath a sink, InSinkErator waste disposal units simply grind up food waste and flush it away down the drain. The waste gets washed to water treatment plants where the waste food is used to make fertilizer. In this way waste food is recycled and does not have to be taken away in rubbish collection and left in landfill. Most things can be ground up in InSinkErator waste disposal units, even small bones but it is a good idea not to grind fibrous waste such as coconut shell as this may jam the waste disposal unit. It is also worth considering the material that your sink is made of. If your sink is stainless steel for example then the waste disposal unit will create more noise as opposed to a granite or ceramic sink.
