Rashi, Deuteronomy 16:13
1 א
רש"י דברים פרק טז פסוק יג
2ב
:באספך - בזמן האסיף שאתה מכניס לבית פירות הקיץ. דבר אחר באספך מגרנך ומיקבך, למד שמסככין את הסוכה בפסולת גורן ויקב
When you gather in [the produce]: [i.e.,] at the time of the ingathering, when you bring the summer fruits into the house. Another explanation:“when you gather in [the produce] from your threshing floor and your vat” teaches that we should cover the sukkah [only] with the waste products that come from the threshing floor and the vat. [Judaica Press translation]

Suggested Discussion Questions:

What is the connection between this source and the principle of Bal Tashchit (Do not waste/Do not destroy)?

Can you think of ways to reuse items that would otherwise be thrown away in your Sukkah?
