Abstract

Introduction: Plastic waste is a non-biodegradable waste that cannot decompose and this will lead to water, land and air pollution. While the plastic waste is burned in dumping site, the percentage plastic waste has increased rapidly. Objective: To produce a systematic review of environmental friendly bricks from plastic especially low density polyethylene (LDPE) plastic as an alternative approach to solve the problem of single plastic use and its association with carbon footprint. Methodology: Research articles for this review was searched from Science Direct, Google Scholar and Scopus. Most of the studies were ranged between year 2012 to 2020. The keyword of the search. Result & discussion: Many studies have evolved different methodologies to reuse waste plastics in the concrete mix, paver blocks and bricks, though they seem still seem to be in the realm of research and development. Eco-bricks with plastic percentage of 15%-25% has the highest compressive strength value while brick with 20%- 35% show the best performance in water absorption test among other plastic percentage. The comparison between plastic eco-brick and conventional show that 13 out of 20 study proved that plastic eco-brick has higher compressive strength than the conventional one. As for water absorption, plastic eco-brick also has better performance than conventional brick. Eco-brick and conventional brick both only show either a slight or no presence of soluble salt on the surface of the brick. Lastly, 70% to 80% of carbon emission is related to the use /operation phase while the rest is associated with carbon emission from materials manufacturing process such as brick and concrete as it is one of basic construction materials that is widely known to contribute to the overall carbon footprint of buildings. Keyword: Plastic waste, eco-brick, compressive strength, water absorption, soluble salt Research area: Environmental health
