The construction industry is under increasing pressure to become sustainable. One way to address this is through the use of reclaimed materials. Reclaimed materials are those that have been previously used in a building or project, and which are then re-used in another project. The materials might be altered, re-sized, refinished, or adapted, but they are not reprocessed in any way, and remain in their original form. Materials that have been reprocessed and reused in the building industry are referred to as recycled materials.
The building industry has a massive impact on the environment in terms of energy consumption, use of natural resources, pollution and waste. Every year in the UK, construction materials account for around: 6 tonnes of materials per person, 122 million tonnes of waste (1/3 of total UK waste) and 18% of carbon dioxide emissions, a major contributor to global climate change. On top of this, the embodied costs associated with the extraction, production, manufacture and transportation of building materials are immense. Using reclaimed materials can significantly reduce these environmental impacts, and save up to 95% of the embodied costs by preventing unnecessary production of new materials, and reducing the amount of waste sent to landfill.
Although there are substantial environmental benefits to using reclaimed materials, the market is virtually untapped. At the moment, only 1% of reclaimed materials are used in new building projects, a percentage that should really be higher. One of the barriers has been a lack of information about sourcing and using the materials in design and development - including knowledge of specifications, standards, legislation and performance. But there are economic barriers too, including the cost of extraction in deconstruction, the limited flexibility of reclaimed materials, and problems of storing and double handling of materials between sites. In addition, medium to large building projects cannot take advantage of the reclamation industry, because the salvage supply chain is not yet equipped to deal with large orders.
