2) Lack of motivation or incentive

35 million water bottles annually Metro Vancouver landfills

Only 13% of bottles are recycled

Recycling 10kg of plastic bottles eliminates 3.3kg of carbon emissions

Recycling 10kg of aluminum cans eliminates 37kg of carbon emission

questions

Key requirements include:• any interaction to remain minimal and intuitive• status of capacity visible• safety of user

These issues were addressed by:• Reverse biased LED proximity sensor• providing four 5x7 LED displays• proximity sensors across oriface

Scanning Methods

Radio Frequency Identification• SeeedStudio RDM630• operation frequency @ 125kHz

Beat Frequency Oscillator• magnetic induction principle• operating frequency @ 3kHz

Laser Profiling• 12 multiplexed lasers @ 3 volts• 12 photo resistors @ 10kΩ to 120kΩ range• number of pairs limits resolution

Pressure Testing•Rack and Pinion System•Process information through optical encoder

Final thoughts

Managed to build a working prototype and display proof of concept.

Meets essential requirements of functional specifications.

We actually learned something – on a technical perspective and on a business perspective

There is a potential for our product. There is a huge market for greener technologies. Responsibility as engineers and as a people to look after our environment.
