Detachable Waste Container for Chopping Board





Introduction: Detachable Waste Container for Chopping Board

Tired of messing up your workspace with offcuts and crumbs while cutting vegetables, fruits or bread?
Tired of running miles to the garbage can - which is just on the opposite end of your kitchen - to clear up your chopping board?

Here´s the solution:

A magnetically attachable and detachable waste container.


- Chopping board (preferably a wooden one)
- Cheap baking pan (rectangular and magnetic)
- Neodymium magnets (cylindrical, I used 5 pieces with 10 mm diameter and 5 mm height, if you use smaller ones, you will need more)


- Drill
- Wood drillbit (matching the diameter of the magnets)
- Sharp knife (optional some more appropriate wood carving tool, a router would be the best choice to do this accurately, but guess what, I don´t own one, so I did it the old school way)
- Abrasive paper (optional, for the pedants)

What to do:

- Align the baking pan to the chopping board and mark the position.
- Carve out a groove at the edge of the cutting board matching the lip of the baking pan (I carved out 5 x 5 mm).
(Note that this will also work without carving out a groove, you can attach the lip of the baking pan directly to the magnets, but that won´t look and work as nice.)
- Drill holes for the magnets into the side of the chopping board
- Press the magnets into the holes (The magnets I used had a diameter of 10.0'something' millimeters, so they stick in place in a 10.00 millimeter hole by friction without adding glue.)
- Attach the baking pan aka waste container and give it a try.
- Cheer.

Thats´s it , have fun :)

Terrific idea! I like it enough to actually do it, and I have the magnets already! Thanks!

cool and clever

How much weight can your waste container support?

I just thought of an idea: you could recess it under the edge of the board and then nothing could fall in between the container and board. Liquids would also run into your pan.

Interesting question / idea.

I made a few quick tests:
With the 5 magnets I used (d=10 mm, h= 5 mm), the container supports about
200 grams when the lip is level to the surface of the board as seen in
the pictures. With more weight added it does not simply fall off, but
will slip downwards a little and the lip will stick to the magnets
"directly" and in this position it will hold about 600 grams without
falling off. Thats´s triple fail-safe tolerance ;)

Why so?
In the baking pan I used, there´s a 3 mm diameter steel wire wrapped into
the lip which is "more magnetic" than the sheet metal of the walls of the pan.

So this may all vary depending on the type, size and number of magnets and the model of baking pan (or whatever container) you might use. If you want it to hold more, add some magnets.
Just try and let me know :)

Regarding liquids, I wanted a solution primarily for solids and one that would align to the edge of the workspace and is easily detachable. The chopping board already has a groove for collecting liquids and there are several commercially available (and pricey) solutions for containers which rest 'under' the chopping board, but that was not my intention.

Hope this was helpful and THANKS A LOT (to all) for your comment(s) and adding it to your favorites:)

excuellent idea, particularly if you are collecting organic items for compost!

Samrt and simple! Like it!
