Technical Report Draft 1

1. Introduction/background information Singapore has implemented many measures to help people with disabilities integrate into the community in the last 13 years (Society for Physically Disabled, 2014). Visually impaired commuters travelling alone, however, are still having difficulties using public buses.

The two main problems faced by the visually impaired are knowing which buses are arriving at the bus stop and whether the buses that they are on have reached their destination (Singapore Association of the Visually Handicapped, 2017). Their predicament was reported by Spykerman (2016) - a visually impaired undergraduate had to alight many stops after her destination when the bus captain had forgotten to inform her and she had to wait for someone to assist her to go to the bus stop across the road to get to her destination.

Statistics on visual impairment in Singapore for gauging the extent of the problem is limited. An estimate derived using the study results of Wong et al. (2012) …

In the article “Duo turns plastic into concrete idea” by Goy, (2016) addressed the economical and green efforts taken by BlueRen company during the process of recycling plastic waste and turning it into carbon nanotubes with the use of a different catalyst. The carbon material then can be used as an additive to enhance the properties of concrete, and also to reduce the amount of concrete used up to 30%. Unlike common recycling methods, BlueRen’s technology focuses on upcycling which converts plastic waste into products of a higher value. While the article only mentions about the resource enhancement, conservation and green efforts with the new method of recycling plastic waste, it did not mention the negative impacts on the environment posed by nanotechnology itself. An example would be, mice exposed to the multiwalled carbon nanotube showed that it causes similar inflammation and lesions compared to asbestos, a cancer-causing compound.

Thesis:

While the article mentioned about the green efforts of recycling plastic waste and carbon nanotube technology, negative impacts on the environment caused by this technology should also be looked into.

Summary

In the article “Duo turn plastic waste into a concrete idea” (Goy, 2016), the green efforts of converting plastic waste to carbon nanotubes with the technology developed by BlueRen company. Many recycling processes done by previous studies on the conversion of plastic waste into carbon nanotubes are not cost efficient and environmentally friendly. However, BlueRen’s recycling process uses a more environmentally friendly mineral as the catalyst and can produce 1,000 tonnes of carbon nanotubes from every 10,000 tonnes of plastic waste. Furthermore, the carbon material can be used as an additive in concrete resulting in the use of cement to be reduced by up to 30%. Unlike common recycling methods, BlueRen’s technology focuses on upcycling which converts plastic waste into products of a higher value.
Dear Professor Blackstone
I am Jerome Tay, and this is my introduction letter. I graduated from Singapore Polytechnic with a diploma in information technology (solutions development) in 2015. I have decided to take on the engineering path after the completion of my diploma as I wanted something more practical, hands on and ultimately, to be able to contribute back to the society with a greater impact. Thus, I have chosen to pursue a degree in sustainable infrastructure engineering (land) in Singapore Institute of Technology.
Strengths
My strengths are analyzing and understanding messages, and being a good listener. Firstly, I am able to analyse and understand messages that are being delivered. It is a skill that I believe it is of utmost importance, as messages are part of our everyday lives and may come in different forms. Secondly, I am also a good listener, as I strongly believe that one would not be able to truly understand the message of the other party unless one is a good list…
