Here is a little diagram I made of what you can get out of a typical plastic coffee maker. The heating area is usually a steel plate with an aluminum heat sink beneath it. Some yards have #2 board or some designation like that for non-computer boards, typically mine counts them unclean aluminum.

Nice diagram. The internal components of small appliances like this vary - older ones have more metal and little or no electronics.

Most of the weight of a modern coffee maker is plastic, so if you're going to break them down it's best to get some credit for that material.

Usually my approach with small appliances is to cut the cord and throw the rest in with mixed light iron/shred scrap or mixed electronics.

Unfortunately, there are no plastic buyers in this region of the country, besides commercial-level industrial plastics.
