What is a Disposer?

A food waste disposer is a modern kitchen appliance. It offers a new way to manage food waste in the modern home. It is installed under the kitchen sink and is attached to the drain.

How Does A Disposer Work?

Food waste is fed into the disposer together with water from the cold tap. The food waste is simply and quickly ground into fine particles, no knives and no blades. The food waste is then flushed through the waste disposer and into your normal waste system. A food waste disposer is designed to cope with most types.

Is A Disposer Safe?

Waste disposers are built to rigorous standards on electrical and appliances. Contrary to what some may think, they do not have knives or blades…an assumed cause of safety concern.

How Long Does It Take To Grind Food Waste?

Only a few seconds, although it depends on the quantity and type of waste. The sound of the disposer will change, when there is no longer any food waste in the grind chamber and the impellers spin freely. After all food waste is ground, turn off the disposer and let the water run for about 15 seconds to flush the waste out of the grind chamber and out to the water drainage or sewer pipes. Only a small amount of water, time and effort is required.

Why Have a Disposer?

Kitchen Hygiene

• Rather than scraping and pouring messy food waste into a kitchen pedal bin, simply turn on the cold water tap, switch on and empty the unwanted food waste into the sink.
• Fewer insects and odours in the kitchen, making it a more pleasant environment for family and social gatherings.

Convenience

• Quick clean-up and preparation of foods.
• Less volume of food waste to remove: studies show that between 25 and 50% of the volume of kitchen waste is food waste

Practical

• A food waste disposer is compact and unobtrusively fits under the sink. It is easy to install either in a new or existing kitchen and can be fitted to most sinks.
• Most forms of food waste can be put through the food disposer – small fish and poultry bones, meat, vegetables, fruit, egg shells and much much more. Very stringy or fibrous foods such as celery should be avoided.

Responsible

• While improving your own quality of life in the kitchen, it is also good to know that you are making a positive contribution to your environment. Not only does it reduce the amount of waste that ends up in a land-fill, but the waste can also be recycled into a soil conditioner at the water treatment plant.

Environmental Benefits

In addition to reducing household waste, a food waste disposer can reduce the amount of waste that goes to land-fill. Waste has become a major global issue and legally binding limits have been established for some countries on the amount of food waste that can be used as land-fill. A food waste disposer can reduce the volume of waste going to land-fill dramatically, by up to 50%. Life-cycle studies have identified major cost benefits from using the food waste disposer rather than land-fill methods alone. Ground food waste channelled to a waste water treatment plant can create valuable fertilizer and generate energy by capturing methane gas. Here is a growing list of environmental studies in favour of food waste disposers. Food waste disposers complement the compost pile. Composting is an environmentally-friendly way to use the space in their gardens to slowly break-down organic matter such as food waste. Composting with food waste is not an option for many people who have neither the necessary space nor the time to tend to a compost pile. Additionally, protein food waste such as meat, fish, dairy products and many cooked foods should not be put on a compost pile. The decay process is different from that of green waste and can produce harmful pathogens, noxious smells and be an obvious attractant for rodents and insects. Many councils/local authorities recognise the benefits of sink waste disposers and offer grants to help with the cost of purchasing a unit.

Fitting

Most Food Waste Disposers are suitable for connection to a sink with an 89mm or 3 ½ inch waste outlet. If you wish to fit your waste disposer to a different size waste outlet In-Sink-Erator offer the option to purchase a waste reducer flange (for use with ISE models only) which can be found under In-Sink-Erator accessories.

Operation

All continuous feed models of Waste Disposals can be operated via an air switch which can be located next to your sink. The Air Switch comes as standard with Models 65 / 75, on all Franke Models and as an additional option on the Model 45. If you wish to use an air switch with a standard ISE Model 45 or 55 you can purchase these separately under In-Sink-Erator accessories.
