2.5 Flashcards
explain green + eco design
green – changes that are made are small in nature – recyclable material, reducing E in manufacturing (re engineering the design to make less environmentally harmul)
eco – more complex approach, more than just materials, considers the entire lifecycle of the product => longer timescale and greater complexity
green design
designing products that have a reduced environmental impact throughout their life
categories for design objectives of green products
materials, energy, pollution/waste. designers will often adress one or two when creating a more sustainable product
objectives of the materials category
-minimising the number of different materials used in a product
-labeling materials to encourage recycling
-using materials with more efficiency
objectives of the energy category
-reduce amount of E needed to manufacture/use a product
-switch to sustainable E sources
-increase efficiency in E use
objectives of the pollution/waste category
-sustainable planned life of product
-minimising potential environmental damage from selected materials
-consider the effect of disposal at end of product life
-ensure durability
green design changes
1) incremental (often driven by legislations):
-recycled materials
-material optimisation
-limit number of materials
-increase E efficiency
-design for disassembly
2) radical
-completely new materials
-completely new manufacturing process
-consider how to meet needs in more sustainable ways
3 main drivers for company to employ green design strategies
1 consumer pressure
2 CSR
3 legislation
prevention principle
minimisation of producing waste in relation to the production + use + disposal of product – actions to minimise damage taken prior to it being caused
precaution principle
anticipation of potential problems related to impact of the product – actions to prevent harm when specific impact is uncertain (like avoiding untested materials)
