Stainless Steel Compost Bin Vs Plastic

Stainless Steel Compost Bin Vs Plastic

Instead of throwing away your coffee grinds, egg shells, vegetable peels and other kitchen scraps, you may want to consider composting them.

With a kitchen compost bin, you don’t have to worry about taking the scraps out to your compost bin right away, nor do you have to leave them sit in a bowl until you’re ready to take them out. The problem some people who do want to get into composting is deciding which kitchen compost bin is better.

We are going to shed some light on that age old question: Which is better, a stainless steel compost bin vs plastic?

Stainless Steel Compost Bins


  • ​Durable construction
  • ​Nice aesthetics
  • ​Doesn’t absorb odors
  • Easy to clean
  • Solid construction


  • ​Heavy when full
  • ​Hardware has the potential to rust

​A stainless steel compost bin is made to last a long time. The stainless steel container is a sleek option for those who want to keep the compost bin on the counter for easy access. The stainless steel is also a preferred option because it doesn’t absorb the odors from the kitchen scraps. This means if you cut a lot of onions, your bin isn’t going to smell like onions even if there aren’t any onion peels in the bin.

The stainless steel bins are also a good option because the material is easy to wash after the bin has been emptied. Also, there will be holes in the lid to promote air circulation, which helps the organic matter break down.

The draw backs to stainless steel bins is that they can be a little heavy once it is full of kitchen scraps. Also, there is a slight chance the hardware used on the bin could begin to rust over time.

Plastic Compost Bins


  • ​Lightweight
  • ​Affordable
  • ​Durable (but not damage resistant)
  • ​Recyclable


  • ​Aesthetically unappealing
  • ​Absorbs odors over time

​Plastic compost bins are designed to be lightweight and very durable. These units will often feature a tight seal that will keep odors in, but will also keep bugs and other pets out. Since these units are made from plastic, they are more affordable than stainless steel and they can also be recycled when it needs to be replaced.


Sadly, that is the drawback to a plastic bin. Over time, odors from the kitchen waste will be absorbed into the plastic material; and all though plastic is pretty durable, it isn’t the damage-proof, as accidents happen and the plastic could crack. Also, plastic compost bins are not the most aesthetically pleasing. This may not be a concern if you intend to put the bin under the sink or somewhere out of view.
