WRAP (Waste & Resources Action Programme) have developed an online tool to help reduce waste generated on construction sites. The toolkit, which is free to use, enables construction clients, designers and contractors to more accurately identify where the majority of construction waste is being generated, what types of waste are being generated and where efforts should be focused to achieve the most environmental benefit and the most substantial cost savings.

This has significant potential for many developers seeking to develop Site Waste Management Plans (SWMP) in accordance with the new UK regulations which came into force in April this year.

The tool calculates a series of metrics and potential savings, including:

• cost of materials that have been wasted; cost of waste disposal;
• tonnages and volumes in different waste streams;
• diversion from landfill;
• carbon impact of waste reduction and recovery; and
• reused and recycled content.

A typical unsegregated construction site skip can contain materials worth up to £1000 and up to 30% of materials brought to site directly enter the waste stream without even being used as intended.

It is estimated that waste awareness and good practice can result in saving of between 1-10% of turnover (Envirowise), representing a significant financial incentive to construction projects who typically operate at very low profit margins.
