How can I dispose of these packing peanuts?

My Dad’s wife is amazing. She sends everyone Christmas and birthday presents, and always right on time….and that’s a lot of presents. She is very, very thoughtful, and I’m truly grateful. However, they are usually packed in packing peanuts and it drives me a little crazy. She’s never had kids so she doesn’t recognize the choking hazard. They’re impossible to keep track of. They can’t be recycled. They don’t decompose. If they end up in the landfill they can kill foraging animals. The only thing I can think of to do is burn them, but they put off dangerous fumes. Could I run them out to a secluded place, like the lake when it’s deserted, put them in a fire pit, pour diesel fuel on them, put a torch to them, then leave the area?
