To many this item is just a tiny little old trimmer pot but I am big on reusing or repurposing old electronic components and hardware, particularly from the point of view of sustainability.
Energy was previously used to dig up the raw materials and process them to produce a finished product, no matter how small.
To then send these electronic components off to the local tip, be buried and potentially leeching poisons into our earth seems so incredibly irresponsible.
HERE is a page I have created which gives some tables and more detailed information about specific Ee values for different materials plus a link which you can use as a starting point to investigate Ee for yourself.
The trimmer pots are all unused, old stock
