There is a company called woolcool in the uk that produces wool sheets to replace styrofoam. The sheets are encased in thin perforated plastic. As as insulator it’s great, but it does get wet and it’s expensive. There are companies using it to deliver temp sensitive goods but if you do you have to get your customers to send it back to you to mitigate cost.

Strip it out of the plastic and a dog or cat will go nuts rolling in it!
