Coffee consumption generates significant waste as spent coffee grounds (SCG) are often incinerated and discarded in landfills. Little has been done to address the waste issue in Singapore, despite rising coffee consumption. Our project seeks to use composting as a means to reuse SCG. A group of home gardeners were surveyed and a majority (>70%) have open attitudes and knowledge about SCG composting. An experiment was also conducted using kang kong (Ipomoea aquatica) to determine the effect of SCG compost on plant growth. The results demonstrated the possibility of using SCG compost to grow plants.
