That is what we do here, the school makes money in addition, as we donate money, when we bring stuff in.
My grandson was on the committee several years ago, and they advertised in the paper and also signs on the way to town and the grocery.
We also have another disposal for toxic chemicals at the other school, same, you take your stuff in and donate.
All this stuff is handled by a company who comes to our town, and they deal with everything, as they know what it is and how to do it.
Then its trucked off to be properly disposed of. This was started about 35 years ago in our town, probably earlier in, and close to cities.
