Garbage Disposal Unit


There’s a reason why non-food items are not allowed on our garbage disposal unit.

Aside from non-food items are insoluble in water, they contain chemicals that may be harmful to our sewage systems and to the environment as a whole.

And take note, the foods we throw down our disposal units go directly to our drainage where it eventually should be deposited to treatment plants.

Sadly, a lot of chemicals found in non-food items can seep through the sewage systems, leading their way to our land fields and even to our water lines. This thought is quite bothersome especially if you consider the environmental and physical harm that the distribution of these chemicals to households can bring.

Below is a table of common things we might be thinking of throwing down the sink including the harmful chemicals that they have and the possible health problems people could suffer upon extreme exposure or ingestion.

Non-food items are created using chemicals so you can’t just expect these basic components to disappear once you flush them down your sink.

If any, you’re only adding more to the environmental risks these chemicals can produce.

The Alternative

Rather than throw non-food items on the sink and risk exposing you and your family to health problems, go for the more appropriate step which is to segregate these non-biodegradable materials.

You may go for placing them at a separate trash bin or plastic bag.

For liquid wastes such as paint and ink, you can bring them to the nearest mobile drop off point where they are regularly collected and disposed safely.

Motor oils on the other hand should be placed inside a safe container and delivered to your local oil collection facility. In there, proper processes will be taken to clean and possibly reuse it.


If you’ve been fond of just throwing almost anything down your sink, then you can at least begin to remove the practice by starting with the following easy tips:

  • Use sink strainer to filter the products that goes down your sink.
  • Place non-food item wastes on a separate trash bag.
  • Use less detergent and choose the brand with lesser salt content.
