What is a green building product or material?
Building projects may offer the chance to use building materials supplied in standard measurements. The less you have to adapt or cut, the less wastage you will incur – not to mention the time and effort saved. Framing layouts can be planned to use standard wood lengths, for instance.
This was a popular building material up until the 1960s when it was discovered to be extremely dangerous – causing chronic obstructive pulmonary disease and lung cancer. However, the material continued to find its way onto millions of rooftops freely – until 1983 when Iceland became the first country in the world to ban all types of asbestos.

Standard Wastage Consideration for Building Materials. August 22, 2018 by Kathir 2 Comments. Steel Materials: Allowable wastage for steel works is 3 %( cutting/bending wastage). For reconciliation purpose, + or 2% allowable for rolling margin in this accounts.
Building designers make the key waste minimisation decisions, including whether an existing building will be completely demolished or partially retained. They decide on the materials being used and the construction methods to be employed. “It’s time we realise that waste is an asset, and not a problem. Through informed design,
The Environment Protection Authority provides further advice about construction waste . What happens to recycled construction waste? The way construction waste is recycled depends on the materials within each item. Find out more about waste and recycling for different materials.
This study will generally talk about reduction materials wastage issues in construction field. Reduce the material wastage in construction is approved in applying reuse, recycling and reduce the building materials in construction activities. This thesis reviews the technology on construction waste recycling and their viability. CHAPTER II

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).
materials wastage in Nigerian construction sites. This formed the basis of this paper, which aim is to quantitatively assess construction materials wastage in construction sites with a view to providing background information on allowable percentage of construction materials waste at design stage in order to enhancing construction project delivery.
Although recycling is not best for some plastics (such as those that are soiled), the material can still serve a useful purpose if used in a wastetoenergy system (WTE). This process involves the conversion and recovery of the energy value in the waste material through the application of high temperature, controlled combustion.
The objective of the research is to identify the major causes of material waste on construction sites in Jordan based on the opinion of contractors, consultants, and owners also to assess the quantities of wastage in main building materials used in the Jordanian construction sites and making comparison with the other countries. 2.
your site best, giving a high waste recovery rate, for the right cost. Sort different waste materials on site. Locate containers ( skips or wheelie bins) close to working areas and use clear signs to show which material goes in each. Keep materials for recycling clean, dry and separate from other materials or waste.
If you're adding on a percentage to your net material requirement for costing, don't add a "waste" factor or you'll be making a mistake I see lots of guys do. If your waste factor is 20%, 25%, 30%, 35%, 40%, 45%, or 50%, add 26, 34, 44, 55, 67, 82, and 100 percent respectively, to your net material requirement to get your actual material costs.
