Although Singapore has a relatively high recycling rate, most of this plastic waste does not end up being recycled due to contamination. Bad recycling practices will end up piling plastics in landfills, which will soon run out of space. It was found that the majority of RVRC students cited inconvenience as the reason why they do not wash their plastic bottles. Our project objective was to build a prototype that helps to wash plastic bottles efficiently. We have designed and constructed a prototype that includes a rinser that washes plastic bottles within seconds. Using our prototype, 96.8% of RVRC survey respondents found it more convenient to wash their plastic bottles and increase in 50.6% of the respondents who are willing always to wash their plastic bottles before recycling. Hence, proper equipment that enhances convenience proved effective in encouraging people to recycle correctly, reducing the amount of recyclables being disposed of as wastes due to contamination.
