In Singapore, a growing coffee market generates an increasing volume of spent coffee grounds (SCG). Our project aims to 1. establish the effectiveness of SCG to be re-purposed as body scrubs, potentially replacing environmentally harmful mircobeads; 2. encourage RVRC students to try making these body scrubs, hence extending the life cycle of SCG. We produced two types of body scrubs with SCG, and improved the first version based on trial and feedback provided by a focus group of 17 RVRC students. Thereafter, we conducted a workshop to pitch and distribute version two of the body scrubs to the focus group for testing again. The focus group rated the second version of the two scrubs as more effective (T-test: p=4.19×10-5 and p=1.09×10-8), and were open to making such scrubs on their own (Chi-squared test: p=2.06×10-5). Hence, focus group testing and a workshop proved effective in encouraging RVRC students to re-purpose SCG.
