Construction waste is a major source of urban waste received at many landfill sites around the world. A number of waste management methods have been in use to deal with the substantial amounts of various kinds of construction waste in order to relieve the heavy waste burden in many cities. To achieve sustainability in urban development, different waste management methods should be carefully exa...

Nowadays, disposal of waste materials has become a matter of serious concern due to environmental and ecological issues. In this paper, an attempt is made to determine an optimum proportion mix suitable for geotechnical applications by blending the locally available clayey soil with sand, fly ash, tile waste and jute fibers. This optimum mix provides a cheaper construction material and helps in...

5 A considerable amount of solid wastes is generated every year from construction and demolition (C&D) 6 activities in Hong Kong. The C&D waste can be classified into inert and non-inert wastes, in which the 7 inert waste is normally disposed of in public fills as reclamation materials, and the non-inert part is dumped 8 at landfills. Under the current waste generation trend, all landfills and ...

Fig. 1. Relationship between waste and raw materials in the production and use of building materials; the lines illustrating areas of interest for Waste Management are emphasized. An ever-increasing number of papers focusing on the use of waste as an alternative material in the production of building materials is being submitted to Waste Management. Indeed, the wide variety of waste components ...

Bricks are a widely used construction and building material around the world. Bricks are prepared from natural waste material which comprises of orange peels and coconut waste. Clay is used as a binding material for natural waste material and paper mill waste. The main objective of the present study is to reduce the quantity of clay with natural waste material. The orange peels and coconut wast...

Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...

As the premier material in construction industry across the world, concrete has major role in the effects of construction to our environment. Consumption of concrete is very high due to extensive use of concrete in many structural applications. The rapid infrastructural growth in developing countries and production of many by-product as waste material making high role to concrete producers in i...

This e-fact aims to raise awareness of the occupational safety and health (OSH) risks associated with the planning and construction of green buildings, their maintenance, renovation (retrofitting) and demolition, as well as the collection of related construction or demolition waste on site (excluding the subsequent waste treatment and recycling). Some of these OSH risks are new compared with tr...

Construction has a substantial impact on the environment. Much energy is used in the: production of materials such as cement, steel, aluminium, wood products, plastics, and paints; movement of materials and components to, and on site, and running and operating of plant and equipment on site. Construction waste, resulting from the construction process, results in the waste of land resources and ...
