Processing Plastic Waste Into Grass Blocks to Support the Zero Runoff Concept in Malang City, Indonesia


Plastic is a polymeric food wrapping material. It is projected to increase in use and has the potential to become a raw material for recycling plants and incinerators in the future. However, decomposing plastic is difficult. This will cause complex problems if not addressed immediately. The purpose of this article was to describe the process of making grass blocks from plastic waste to implement the concept of a ‘zero runoff green city’ in Malang City in particular and Indonesia in general. An experimental analysis design was used which explained the stages of making grass blocks. It was shown that grass blocks can be made from plastic waste and a mixture of sand and cement with a ratio of 1:3 (37% sand). The grass block had a compressive stress of 17.2 Mpa with a length of 20cm and a height of 60mm. \
