In an article “Duo turn plastic waste into a concrete idea,” Goy (2016) reports technology company, BlueRen aims to commercialise recycling of plastic waste into a concrete additive, which will in turn reduce the use of cement in making concrete. Unlike conventional methods of recycling, BlueRen uses a more environmental-friendly mineral as the catalyst and could produce a 10 percent output of carbon nanotubes from the plastic waste product in 2016. This in turn will reduce cement consumption by 30 percent. With BlueRen’s technological breakthrough, the long-incubated recycling process of the industry can finally be upscaled while ensuring that the previous level of cost and harmful environmental drawbacks is at minimal. Recycling and reusing of waste products in making concrete will benefit consumers when purchasing HDB flats in Singapore in terms reducing carbon footprint and possibly reduced prices.

During my national service, I was given the opportunity to become a representative for my unit as a "welfare IC". This required me to attend meetings on a …
