Packaging materials
Packaging will be presented and discussed from the performance perspective, in certain applications with a focus on food stuffs, including product safety (especially materials and barriers perspective), economics/services (systems perspective), communications and marketing, logistics, design and sustainability. Materials used in packaging, and some of the converting processes, will be covered, such as glass, metals, polymers
Scale up perspective on renewable processes
Successful process scale-up is critically important when taking an innovative idea and turning it into a commercial reality, while successful process scale-down is essential for troubleshooting or optimizing commercial processes. The course will give lectures on pre-planning of pilot and large scale processes and the laws and permits that are needed for building a plant.
