In particular, the present invention has been developed for the prolonging of the food-grade shelf life of warm wet biomass feedstock such as brewers spent grain to enable the transport from a brewery to downstream processing facility. In one embodiment this could be a renewable electric-powered heater jacket that maintains a specific range of conditions, made from a particular robust insulating composite material. However, it will be appreciated that the invention is not limited to these particular fields of use.
