Recycled Materials 2
Introduction
The built environment is the world’s largest consumption of natural resources since it
accounts for 40% of the extracted materials in the most industrialized countries, with 70% of
electricity tapped from the energy sources, 12% of portable water, and 46%-65% of waste
materials disposed on the landfills (Ameli & Brandt, 2015). This figure is expected to increase
due to high birth rate that is currently experienced in the world lead to high population influx in
our cities. The world population of 6.5 billion recorded in 2005, is expected to increase
drastically to around 9.5 billion in 2035 (Anderson & Shiers, 2009). As a result, the mitigation of
securing the future of our environment due to the impact of buildings is a primary concern that
the world should look into so as not to compromise the future generations.
Given the impact of construction materials have on the building’s sustainability, quality,
risk, procurement, safety, procurement, cost and productivity, their selection is a key to proper
development of building project and is considered to be the main factor affecting the efficiency
and productivity of construction projects. These issues significantly address the appropriate
selection methods for a construction project since deficient or poor choice of materials can lead
to significant losses of productivity on site.
As a result, the recycling of building materials such as insulation material, concrete,
aggregate, timber and steel have gained interest and concern all over the world. The current
trends and practices of building waste management are examined form cradle to grave concept of
the building life cycle. The construction of waste management techniques that depend on
recycled materials have proven to have more economical benefits for the construction industry.
According to Arulrajah, et al. (2012), reuse is the prevention of solid waste from being disposed
on the landfills, and increase the education, material by, making use of materials discarded on the

environment by people who no longer need them and provide them as inputs for construction. In
most scenarios, the reuse of materials significantly reduce the raw materials for construction to
greater advantage of the developer. Moreover, these practice may reduce the overexploitation of
natural resources in the industrialized countries
In most cases, construction companies find it difficult to manage the information gained
on site that is associated with recycling of materials. Managing such knowledge can be difficult
hence leading to the loss of such innovations since it is regarded as tacit knowledge that is
obtained personal construct theory (Dixit, et al., 2010). This report seek to explore the strategies
used to consider when selecting construction materials, techniques and structural system for
building. Our selected material in these case will be recycled materials such as insulated
materials, timber, steel, concrete, aggregates etc. the report will further address the advantages
and potential issues associated with recycled materials for construction.
When selecting the materials used in construction, it is sustainable to consider the cost,
aesthetic appeal, and availability of the material, low carbon content materials, materials that can
be recycled and reused in abundant supply.
Recyclable materials
According to Bolden, et al. (2013), utilizing materials that can be reused will greatly help in
reducing the production of new materials in the future.
