Take-back schemes

Once on site, the most effective waste reduction and recovery measures were found to be establishing and monitoring a comprehensive site waste segregation strategy, and arranging ‘take-back’ schemes with ceiling tile suppliers and for timber pallets.

reduction and recovery from the outset that maximised the savings. Combined, the efficiencies associated with reduced waste disposal costs, the avoidance of Landfill Tax, and less wastage of materials delivered a cost saving for the project estimated at £650,000, net of implementation costs. A significant sum in an industry operating on the smallest of margins. The key action for a local authority client is to set clear outcome requirements for minimising waste in the Project Brief or Output Specification and

maintaining a consistent “ask” through the supplier selection, tendering and contract processes. Partnerships for Schools’ model procurement documentation includes a number of core waste requirements for school building projects: • forecasting waste from the design stage

• identifying actions to be taken to re-use and reduce waste

• increase recovery and increase recycled content

• including performance targets in a Site Waste Management Plan (SWMP)

•measuring and reporting on performance. “We recognise that in the current economic climate, focus rests firmly on the bottom line but we’re keen to communicate that sustainability and cost efficiency really can work in unison,” explains Jennifer Decker, key account manager at WRAP. “To enable local authorities and their project teams to implement waste reduction measures and secure the associated benefits, WRAP has developed a suite of tools and guidance documents. These are all freely available on the WRAP website and will help clients to drive waste reduction and recovery from the outset of the project, and ensure a collaborative approach with their supply chain partners.”

WRAP’s tools

and guides:

• New guidance at www.wrap.org.uk/ constructionclient identifies how to cut project costs, actions for project managers, and what to do on smaller projects;

• Model procurement wording at www.wrap.org.uk/procurement can help local authorities ask for good practice during the appointment of designers and contractors;

• Design teams can use web-based tools to quantify the cost saving potential (at www.wrap.org.uk/ nwtool) and guides to help design out waste (at www.wrap.org.uk/

designingoutwaste);

• A template for designers and contractors to create a good practice SWMP is available at
