If you are looking to recycle it in Portland, you can try Office Depot (apparently, they recycle electronics), EWaste Solutions, or City Recycle. Earth911.com offers other ideas.

...The door? The refrigerator/freezer (though it requires a manual interface, in which you take the food out of the freezer and put it in the microwave by hand). Also, the buttons on a microwave might be considered an input device. There is no microwave input device in terms of home computers (with the possible exception of a hack that allowed you to control it via USB or something, but I've never heard of that being done). A cell phone or Blue Tooth device might be considered a "microwave device," or maybe a 3G or 4G device such as an adapter or hub. That frequency range of radio waves is considered microwave energy.
Best Buy has a program where they will recycle eWaste. Any type of eWaste no matter where it was bought, they will take it and recycle it. This means that they will make the attempt to refurbish it, and sell it, or they will bring it to a recycling center and attempt to reclaim the value of the precious metals in the electronics.
A microwave oven is called a 'microwave' because that is the type of radio wave it uses to induce heat. An RF wave with a frequency between 300 MHz and 300 GHz is considered a microwave. Microwave ovens typically operate around 1-2 GHz. It is always surprising as to why they are called micro waves when their frequency is in Giga range. Its because, their wavelength is in micron range.
No you cannot microwave regular bacon, it will be raw... Yes you can. They even make special racks for bacon to be cooked in the microwave. Of course it has to be cooked until its done but the same is true when you cook it in a pan.
Because microwave circuits in waveguide use hollow waveguide sections with flanges to bolt them together.
A microwave is, in fact, a microwave
The microwave oven began to be considered a household item in the early- to mid-1980s. I bought my first microwave oven (in Australia) in 1983; it was a Panasonic Genius.
