Being near 40 and having all these cassette tapes that testify to prior poor judgment or bad taste in music, I want to get rid of the evidence. Natch. But I read that they are made from tensilized polyester which doesn’t fall into anyone of the recycling categories. Thrift shops might be able to take the recognizable ones. Schools and libraries might have a need for erased tapes.Sun Valley Worldwide, Ecodisk or Lacerta might be able to do it but probably only does large amounts from businesses. Perhaps I can gather up tapes from friends and relatives and have a big 80s send-off.
