Transcript of Chair Re-Designed to be Eco-Friendly and Sustainable
Wooden Chairredesign
Current Chair Specifications
Chair Functions
● Functional for school environment● Back strength of 68 kg, 150 lbs● Seat strength of 102 kg, 225 lbs● Comfortable● Minimum lifetime of 10 years● Quiet to move
EcoDesign Pilot Results
● Raw Materials: ○ Select the right materials○ Raw material and disposal intensive○ Materials not recyclable, but renewable
● Manufacture:○ Reduce energy consumption in production process○ Move toward energy efficient production○ Optimize design for less energy use
EcoDesign Assistant Results
Recommendations:● Reduce energy consumption and avoid waste in
production process● Optimize types and amount of process materials● Recycling of materials● Improve disassembly
Redesign Targets
● Maintain quality and comfort for consumer● Reduce number of materials● Simplify the manufacturing process● Simplify the recycling process
New Design
Materials Involved
● Frame: Aluminium● Seat: Reclaimed Polypropylene
Benefits of Materials
Aluminum:● 40% post-consumer and industrial waste● Uses 17x less energy during production● 100% Recyclable● Product life around 150 yearsPolypropylene:● Tough and flexible; good fatigue resistance● Can be reused easily, sometimes through curbside programs
Disassembling
Alternative Energy
● Costly to change factory to harvest alternative energy
● Consider lobbying
EcoDesign Pilot Results:NeW Design
● Raw Materials: ○ Material is no longer renewable○ Completely recyclable○ Parts are easily separated
● Manufacture:○ More energy efficient manufacturing equipment○ Regional material use
Environmental Communication
● Recycling Rate ● How to properly recycle product● Ecolabels● Proper marketing
ISO Labeling
● ISO 14021: Self-labeled as “environmentally friendly” or sustainable. Requires product to be recyclable
● ISO 14024: Required transparency in material selection and product function; eco product labels
product labels
Recyclable Made with Polypropylene
Aluminium Material
Recycling Program
● Return chair for discount on new products● Allows for easy recycling● Reduces supply cost
Results of redesign
Cons
● New design is heavier
● Must purchase new equipment
● Not renewable
● Non-traditional look
Results of redesign
● Material is less expensive and easily recyclable
● Cheaper to produce
● Less energy required to manufacture
● Simplified production process
