The Use of Waste Materials in the Construction Industry
Waste materials are a major environmental problem, which is a threat to the environment. It is important to reuse these materials and dispose of them. Waste can be used in the construction industry in two ways: by reusing (reuse components) and recycling (processing waste into raw materials used in the production of building materials).

Material Wastage on Construction Sites Work
Waste is measured by size or weight and is unwanted or useless materials. Construction waste can be divided into material, labour and machinery waste, however, material waste is more of a concern because most raw materials come from non- renewable resources. Construction waste is generated by construction activities. 2.

How Buildings Impact the Environment
There is a huge environmental impact associated with the extraction and consumption of raw materials for the use of building materials. Not to mention the actual production of those materials in their final form. According to the USGBC, 40% of the world’s raw materials are used in the construction of buildings. Waste From Building ...
Plastic in construction
Plastic in construction - Designing Buildings Wiki - Share your construction industry knowledge. 'Plastic' is a general name given to a wide range of synthetic materials that are based on polymers. The construction industry uses plastic for a wide range of applications because of its versatility, strength-to-weight ratio, durability, corrosion resistance, and so on.

Building materials and how to minimise the amount of waste
It says that use of plastics has increased in the sector as a result of more being used in new products (such as shrink wrap) and established building materials (such as pipes) changing to plastic from other materials. The large and increasing use of plastics in building has some advantages for the environment and some disadvantages.
Construction waste - Designing Buildings Wiki - Share your construction industry knowledge. Construction activities can generate large amounts of waste materials that then need to be disposed of. In addition, at the end of a building's life, it may be deconstructed or demolished, generating significant amounts of waste. Construction waste includes waste that is generated during construction ...
The Concept of Waste as Understood in Lean Construction
“Recent studies in the USA, Scandinavia and this country [UK] suggest that up to 30% of construction is rework, labor is used at only 40-60% of potential efficiency, accidents can account for 3-6% of total project costs, and at least 10% of materials are wasted…The message is clear - there is plenty of scope for improving efficiency and quality simply by taking waste out of construction” 1.
Eliminate Waste in Design Phase
Green building efforts for site-built construction focus on reuse, recycling or diversion of waste that is generated on site. With off-site construction, however, the materials can be managed prior to leaving the factory, offering a much more efficient process to reduce the amount of waste sent to landfills.
