Just buy reusable mesh bags and stop wasting plastic to protect your produce for a 20 minute car ride.

The “waste” is negligible; doing some napkin math, a 20 minute car ride accounts for 300 times higher carbon footprint than a plastic produce bag (can elaborate if you want). A reused mesh bag is going to be less hygienic and less convenient, and factoring in the higher footprint of production and distribution (produce bags come in packs of 3500) you would need to get a lot of reuse out of it to even be worth it. Considering impact of disposal, as long as you live somewhere that has sane waste disposal and doesn’t empty their trash into the ocean it’s not going to be significant either.
