Greenwave Environmental Care Competition

20150119_110811 (2).jpgFour students from Anglican High School (From Left: Alexis Yeo, Jasmine Teo, Trina Ng and Erika Goh - All from sec 2E 2014) embarked on the Greenwave Environmental Care Competition 2014 where the students researched on ways to make a difference to the Environment in Singapore. The team chose to work on the project "Home Based Cat Litter made of unused newspaper" and began working their way in proving their initial hypothesis that it is possible to de-ink newspapers and therefore turning it non-toxic so that cats can use the end product in the form of a cat litter. 

The team worked hard and conducted regular experiments even during the school holidays in order to find the most efficient, common and yet accessible chemical that can be used to de-ink the newspapers. After 6 months of continuous experimentation, the team's effort was rewarded when it was discovered that it is possible by using common household chemicals such as Clorox and Vanish to carry out the ink removal process. After experiencing the first breakthrough, the team continued its quest by finding ways to turn the de-inked newspaper pulp into cat litter using methods such as washing, blending, sieving and moulding. In order to ensure that the end product is safe to be used, the team also has to carry out several quality tests. 

As part of the requirements for first round judging which took place in July 2014, the team has to put together a detailed report together with our AHS JEAT cat litter prototype which was submitted to the organizing committee. After making it through past the first round, the team has to make an oral presentation to a panel of judges which included professors from National University of Singapore (NUS), representatives from Ministry of Education (MOE) and representatives from SembCorp Marine as part of the second round requirement. After some intense competition from other schools like Raffles Institution, Raffles Girls' School and Hwa Chong Institution, the team emerged victorious and clinched the 1st prize in the Secondary School category. The team was also featured in the local newspapers for having achieved such an impressive feat.
