Life cycle assessment of bricks made from waste of building material and plastics (LDPE and PET)

Abstract

Plastic waste is the one of the common problem in many countries. The main reason is because the a non-biodegradable materials. There are two types of plastic that we discussed in this research, the first one is PET (Polyethylene Terephthalate) which is a type of plastic that often used as a bottle of soft drink packaging and the other one is LDPE (Low Density Polyethelene) which is also widely used as a food or beverage packaging material. The utilization of these two types of plastic continuously without good recycling will have a negative impact on the environment. Waste of building materials is also be a serious problem for the environment. This research aims to provide a solution to the problem of plastic waste above and also building material waste by making it as a mixture to be used as brick. There are various methods for evaluating energy and raw material consumption, emissions released into the environment, and other wastes related to the life cycle of a product or system. Therefore, the method can be used thoroughly from various aspects, the Life Cycle Assessment (LCA) method is the most appropriate method, because it is a holistic approach system that aims to quantify potential environmental impacts (climate change, non-renewable energy use, etc.) generated from the product life cycle, starting from the acquisition of raw materials, use, recycling, and final disposal.
