Second Sindh Research and Technology Showcase 2023 organized by Sindh Higher Education Commission in partnership with NED University of Engineering and Technology Karachi, highlights indigenously developed technologies/products/services from the Universities and Higher Education Institutes of Sindh Province to the relevant industries, government bodies, R&D organizations etc., for the promotion of research and commercialization culture to create significant impact on the Pakistani society.
The project exhibited at 2nd Second Sindh Research and Technology Showcase comprises the development of reinforced plastic composite construction blocks .The production of plastic waste negatively impacts our ecosystem and contributes to air pollution. These high production rates prompted us to research and investigate the possibility of using plastic waste. Plastic brick, also known as eco-bricks or bottle bricks, are a relatively new invention that has gained popularity in recent years as a solution to plastic waste. Traditionally, bricks are made of dried clay, but recently much research has focused on using waste as an alternative material for traditional bricks. In this research project, thermoplastics waste such as high-density polyethylene (HDPE) and polypropylene (PP) are used to manufacture building blocks through a recycling process. They are preferred over other materials because of their light weight, low cost, low density, superior strength, durability, ability to be easily formed, excellent impact resistance, and mechanical properties. A comparison is made between plastic brick walls and conventional brick walls according to compressive strength and fire resistance tests. The exhibition highlights the immense benefits of polymer bricks, ranging from their reduced environmental impact and energy efficiency to their enhanced durability and design flexibility. Incorporated by Bigger Bricks, a temporary rehabilitation center built of ABS bricks was also shown for better exposition.
The event features a range of exhibits that demonstrate the applications and advantages of polymer bricks in various construction projects. From residential buildings to commercial structures, visitors will witness the seamless integration of polymer bricks in architectural designs, showcasing their adaptability to different styles and construction techniques.
