Sylvia,
The WEEE directive states (Annex II, Point 1, last bullet):
"electrolyte capacitors containing substances of concern (height > 25mm,
Diameter > 25mm or proportionately similar volume)"
A rod 25mm high and 25 mm in diameter has a volume of 12.3 um^3. Since
converting to cubic mm is always an exercise that takes me 10 minutes to get
right, I'll leave that part up to you. 8-)
Here's a working link to the WEEE directive:

Cheers,
Marko
Volume of a rod = height x Pi x Radius^2

Hello,
I saved an old email below regarding electrolytic
capacitors. Could someone elaborate on what is the
specified volume of substances to be of concern within
the electrolytic capacitors? I tried using the link
provided below and couldn't found what I need.
Looking forward to your prompt response.
Best Regards,
Sylvia

After some additional research, I found my answer.
Electrolyte capacitors
contain substances of concern if the volume of the
device exceeds a
specified minumum. In that case, the metals are to be
recovered and the rest
is to be treated by high temperatures. Additional
information on the WEEE
recovery process can be found in
