Interesting topics conveyed in this talk:
Biodegradability is a material property not a definition of environmental benefit. I think this a is good point to consider in sustainability as when we see brown paper vs plastic bag we thing paper is greener but it is not when it looked at from life cycle assessment angle. Functionality defines environmental impact. Design is not about using eco-materials; there are very few materials that we should avoid ,rest of it is all about application.
She explains about behaviour changing product, one way to address sustainability issue. Lot of times the problem is not in the product it is in the use phase of the product where it is used inefficiently by the consumer.
Products should be designed with disassembly of materials and components in the end; Starting a closed looped system or product service systems
Consumption is the biggest problem; design is the powerful solution
