Abstract
Reducing inorganic waste, especially plastic has been widely carried out in Indonesia using community-based principles through waste banks. However, the reduction is only limited to economically valuable plastic waste such as plastic bottles but leaves behind large amounts of non-economical plastic waste such as multi-layered plastic packaging, plastic bags, mica, and styrofoam. This research aims to assess the potential of non-economic plastic waste to become paving blocks. The current research was conducted using multi-layered plastic (100%)- styrofoam (100%)- mica (100%)- multi-layered plastic: styrofoam: aggregate (60%:20%:20%, w/w/w)- and multi-layered plastic: mica: aggregate (60%:20%:20%, w/w). All experimental paving blocks were measured for compressive strength and water absorption ability following to Indonesian National Standard No. 03-0691-1996. The results showed that all experimental paving blocks do not meet the standard of Indonesian for compressive strength. Nevertheless, all of paving blocks were observed to have met the water absorption quality standards for grade D paving blocks with a potential of 1.471-4.879%. Based to the results, non-economic plastic waste has a potential to be used as substitute for paving blocks, although further research is still needed.
