Rav Shlomo Zalman Auerbach: Throw Out Your Old Junk, Your House Is Not a Junkyard
A husband and wife had a disagreement on what to do with old items sitting in the house collecting dust. The husband wanted to throw them out while the wife insisted that he find someone who could use it and not throw it in the garbage. Rav Shlomo Zalman answered that obviously it’s best if there is someone else who can use it but if not, they should trash it without any hesitation.
Why? Firstly he said one needs to keep order in their house and not live in a junkyard of “Shmattes”. Secondly it is not Baal Tashchis because searching for someone to take it if there aren’t any readily available takers is Baal Tashchis of your precious time which is more important not to waste. (Aleihu Lo Yibol YD 158)
