1. Waste = food Lesson three: Designing food packaging Learning objectives: To learn about the materials available for packaging that are compostable To know and understand what the definitions of compostable, biodegradable and degradable are with regards to bioplastics To design and model different kinds of packaging ideas

2. Design requirements Your brief is to: Design packaging for festival food Design a package that will compost after use Consider how this material could be adapted to be of benefit to the environment Activity: Create a mind map of different festival foods and a sketch of the packaging that would typically be used.

3. Definitions Biodegradable plastics Compostable plastics Degradable plastics

4. Materials Three main categories of bio-based plastics: Natural polymers from renewable sources Polymers synthesised from monomers derived from renewable resources Polymers produced by microorganisms

5. Case study: Mater-Bi® by Novamount Mater-Bi® is a family of bioplastics It comes in a granular form Its applications include packaging, toys, and biofiller Mater-Bi® is biodegradable

6. Rethinking packaging Using circular economy thinking we could completely redesign packaging. If it is made from completely compostable materials, and even incorporates seeds or fertilisers, it could benefit the soil. Look at the material fact files for compostable bio plastics.
