Once i had an idea: instead of styrofoam or packing peanuts just use pop corn or puff rice. Thermal insulation, shock absorbent and biodegradable! Not sure about flame resistant. Also reusable. Make a mash, add some amylase and yeast and you can distill biofuel. Win-win.

EDIT: (fungal aspect) seed it with the right spores for container shipping and you get some free penicillin upon delivery!
