PROJECT TITLE: Environmentally Friendly Bricks & Blocks
PROJECT DESCRIPTION: Environmentally Friendly Bricks & Blocks Recycling of construction and demolition waste Construction and demolition (C&D) wastes represents a large proportion (44%) of the solid waste stream in Hong Kong. To reduce waste and refuse, recycling the C&D waste has become a very important issue faced by the Government and the community at large. The PolyU has invented a method of using the recycled aggregate for the production of environmentally friendly bricks and blocks that could both reduce the impact on land-fill and also to provide alternative products for commercial usage. The environmentally friendly bricks and blocks are cast using recycled building construction aggregates. Their compressive strength and transverse strength meets the relevant specifications and can be used in the construction industry of Hong Kong. Furthermore, the PolyU research team has successfully invented a new method using the photo-catalytic sensitive chemicals with recycled aggregates to enable bricks and blocks to absorb and remove air pollutants when subjected to sunlight.
