Fact or Fiction: Are Sink Disposals good for the environment

You may not be aware, but dumping food waste into landfills is extremely harmful to the environment. Moreover, landfills are running out of space rapidly. So it’s high time we look at alternative methods of food waste disposal.

But what are these alternative methods?

Some people swear by sink disposals, also known as ‘InSinkErators’, claiming they are the answer to food waste disposal but are they?

If you don’t know what sink disposals are, don’t worry – I’m here to help you. As someone in the waste disposal industry, I certainly know a fair bit about all waste disposal methods, including sink disposal units.

So, continue reading this post to find out more about sink disposals and whether they are good for the environment. By the end of this article, you’ll understand whether you should invest in a sink disposal unit or use other means.

What are sink disposals?

Sink disposals are devices that are installed underneath kitchen sinks between the trap and the drain. These devices are electrically powered, and they can shred food waste into tiny pieces. This way, the waste gets shredded and passes through plumbing – eventually ending up back at water treatment plants.

Key: The food waste gets treated with water and does not end up reaching landfills.

Are sink disposals environmentally friendly?

Sink disposals are more environmentally friendly than dumping waste into landfills. In landfills, food waste decomposes anaerobically to produce harmful greenhouse gases such as methane.

With sink disposals, food waste only needs to be treated, making it a more environmentally friendly option.

Conversely, environmental experts reveal that sink disposals are not the best way to dispose of food waste. This is because the waste still needs to be treated. Composting or reducing food waste altogether is the best option.

If composting isn’t an option for you, you can always hire a green waste skip bin.

Key: Sink disposals are more environmentally friendly than landfill but not the best option available.

Green waste skip bin – best for food waste disposal

Hiring a green waste skip bin is certainly the most environmentally friendly way to dispose of waste.

Simply hire a green skip bin and have it delivered to your location. Once the skip arrives, fill it with your food waste, and the skip bin company will then collect it for composting when you’re done or after the hire period ends.

At 4 Waste Walk-In Skip Bins, we offer green waste skip bins for hire across Brisbane Southside. Do note that we accept only 100% green waste in our green skip bins and no other waste. Rather than sending this waste to landfills, we help recycle green waste into mulch, compost and soil conditions.
