Sustainable Management of Construction and Demolition Materials


Construction and demolition material are debris that is generated during construction, renovation and demolition of roads, buildings, bridges or any other armament structure. By sustainable management of such debris, development is possible without necessarily mining new material. This way the materials will be available for current and future development.

Any material that is generated when new structures are brought up, when renovating the existing ones or demolition of unnecessary civil engineering work fall under this category. Some of the bulky materials that come as a result include metals, asphalt, wood, concrete, glass, plastic among others.

By reducing the amount of such waste going to the landfills or incinerators lead to the reduction of adverse environmental impact associated with mining and consumption of raw materials, a creation of job with recycling industries, reduce the building expenses and less development of landfills.

How does one get to contribute?

Reduction of existing construction and demolition materials.

By reduction of materials used, one prevent waste material generation. It one of the highly recommended way of addressing the solid waste problem. Reusing and recycle are other important method of waste management but reduction prevent waste from being generated.

Some of the ways to reduce C&D materials include optimising the size of new buildings, preserving the already existing buildings, designing buildings that will be used for a long time, adapting alternative framing techniques and reducing interior finishes.

Recovering and reusing such materials

Demolition should be done in a careful way such that the debris remain useful. This will save money which could have being used to purchase similar new materials. Some of the material that could be reused include doors, appliances and fixtures.

Brick, masonry and concrete can be recycled on the site as fill. Packaging materials can be taken back to the supplier for reuse.

Recycling the materials

Most of the C& D materials can be reused. Wood, metals, asphalt have all being proven to be beneficial in construction. For example, metal can be melted to make other metal products and wood recycled to make furniture. The demand for such recycled products is high, so it is a money return guarantee.

However, most of the materials sent for recycling purpose end up mismanaged. Before handling your recycler the material, conduct an interview to ensure they comply with the state and local recycling regulation, are licensed and guarantee proper management of your construction debris.

Rebuying the C&D materials.

To make this possible ensure that the materials collected go to the reuse and recycle program. This will boost the local economy, lower the cost of renovation and new construction as well as preserving the local architecture character.

There is a lot that can be done to improve how construction debris is managed. Your contribution to sustainable practises ensures that the current development does not interfere with the development of the generations to come.
