- WRAP’s vision of a world without waste, where resources are used sustainably. Our mission sets out that we need to help businesses and individuals reap the benefits of reducing waste, develop sustainable products and use resources in an efficient way.
- Since its inception, WRAP has worked with businesses, consumers and local authorities to reduce waste. Projects commissioned by WRAP are expected to save 15 million tonnes of CO2 equivalent over their lifetimes. Over time we have extended our work to include activity right around the resource efficiency loop as you can see here.
- England In June 2008 the Government launched the Strategy for Sustainable Construction. This is a joint industry and Government initiative intended to promote leadership and behavioural change, as well as delivering benefits to both the construction industry and the wider economy. This strategy includes specific targets across a range of sustainability indicators, and these have been adopted as The Construction Commitments by the Strategic Forum for Construction, on behalf of the construction industry. For waste, there is a commitment to halve the amount of construction, demolition and excavation waste sent to landfill by 2012, through waste reduction, recycling and recovery. There is likely to also be an aspirational target to reach the goal of zero waste to landfill (which is the published policy goal in Scotland), which would require the sector to go much further in reducing and recovering waste. There is no date set for this. So, regarding halving waste to landfill by 2012, WRAP has put in place a framework to enable the construction sector to take practical steps in the delivery of this target.
- All levels of the supply chain have signed up to deliver their own key actions Slide 3: Construction Commitments Everyone in this room in some way will be looking to play your part in reducing waste and avoiding landfill: CLICK
- This a supply chain breakdown of the current number of signatories. Slide 4: Construction Commitments (part 2) (UPDATE NUMBERS ON SLIDE FOR EACH EVENT) Wherever you are in the supply chain, you have your own 5 key actions, including measurement and reporting. As you can see, we have signatories right across the supply chain, and particularly among clients and contractors.

- The way the approach is embedded is summarised here. Corporate commitment is made at a high-level within the organisation, ideally by signing-up to the Halving Waste to Landfill Commitment. This sets a mandate within the organisation for Designing out Waste actions to be undertaken as a standard approach. Implementation then needs to occur at two levels – corporate and project. Corporate implementation is through policies and processes being amended to include the commitment and target to play a part in reducing waste, with associated reporting of progress. Designers may require training in the techniques for Designing out Waste, as will be presented through this event. Implementation then occurs within individual projects, by designers identifying opportunities to Design out Waste and developing these into practical design solutions, and through engaging with the supply chain. This is undertaken by using the Designing out Waste process which will be presented later on today. This process includes quantification of the waste reduction benefits provided by the design solutions, and this project level performance can then also be used to contribute to the corporate level reporting. The Construction Commitments: Halving Waste to Landfill has been embraced by the construction industry, with a many major organisations signed up, setting clear waste targets and implementing the actions. Since it was launched in October 2008, over 250 companies have now signed up, including many of the largest and most influential companies involved in construction in the UK.
- [MAIN POINTS] The Construction Commitments: Halving Waste to Landfill has been embraced by the construction industry, with a number of major players already signing-up and setting clear waste targets. This slide shows organisations already committing to the voluntary agreement – over 90 since it was launched in October 2008. Expect that many of the delegates’ clients are shown here. The agreement is also supported by the Strategic Forum for Construction, British Property Federation, British Council for Offices, Constructing Excellence and the UK Green Building Council. Organisations are also setting standards in procurement requirements – for example, Land Securities, British Land and the Olympic Delivery Authority have minimum targets for recovery of construction and demolition waste. Clearly these companies see the targets as technically and commercially sensible. But we know they still have work to do in getting all their sites to take action and ensuring a consistent approach. Sector-wide action should help. Your delegate pack contains background to the agreement, the actions for designers and details about how to sign up.

- And this slide shows some of the Designers & Consultants, Manufacturers & Suppliers, and WMCs who are already signed up. You will see that RIBA and the ICE have also signed up as sector bodies. Through this they will be influencing their members to help tackle construction waste. If reducing waste in your projects is not an aspect you have considered so far, then I hope that today’s workshop will demonstrate the reasons why you should, the benefits you can obtain, and how to go about it. Furthermore, clients and contractors are now exerting their influence on their supply chains and project teams to ensure waste reduction is implemented.
- WRAP provide resources on putting in place appropriate procurement requirements to ensure W2L commitments are supported throughout the supply chain. The reason for setting corresponding procurement requirements is to effectively link corporate targets to the project level and supply chain. For construction clients advise is given on how to set procurement requirements on construction projects. For contractors it sets out how to implement requirements down the supply chain. All can use the model wording provided to make corporate W2L targets an explicit criterion in the construction process. Bring this slide to life - speaker to use examples. e.g. The procurement document gives you model wording to ask contractors, SUB-contractors, WMC’s for data to report appropriately. The procurement process and putting in place appropriate and binding contractual agreements is vitally important for the successful delivery of each of the supply chain levels W2L commitment. The project level process of procurement is dealt with in the proceeding presentation.
- MAIN POINTS Opportunities to reduce waste occur at every stage of the construction process, even at the project review stage when lessons to apply to future projects can be identified. The best opportunities to reduce materials use and waste in construction occur in the early stages of the construction process. Decisions made throughout the evolution of a design can have a major impact on the levels of materials used and waste which arises during the physical construction, and future maintenance, refurbishment and end of life phases of a project. Designers therefore play a key role in reducing the amount of construction waste generated.
- The Designing out Waste : A design team guide provides design teams with a systematic approach to identifying opportunities to reduce waste at project level . The guide is based on key principles distilled from extensive consultation, research and work carried out by WRAP directly with design teams. The guide details the Design Review Methodology which should be implemented at a project level to help identify and assign waste reduction design opportunities. The guidance within the document is intended to be adapted to suit the specific requirements of each project. The guidance provides a key reference for design / consultancy signatories and those who are meeting design waste minimisation requirements set by their clients. MAIN POINTS Five basic design principles, which support the process of DfRE by categorising the potential opportunities: Design for Reuse and Recovery; Design for Off Site Construction; Design for Material Optimisation; Design for Waste Efficient Procurement; and Design for Deconstruction & flexibility. All five design principles should be considered The principles give designers, clients and contractors a systematic structure for considering all waste reduction options. WRAP has developed a methodology to assess and prioritise options available. This has been successfully used on the exemplar projects.
- Net Waste Tool has been used to determine the potential savings. Potential savings – refers to the savings possible through moving from baseline practice to good practice site waste management and recycled content. The savings relate to reducing wastage on the top components of the project. Cost to achieve saving – refers to the additional costs incurred in order to realise the potential savings (might include additional skip hire, contractor time to monitor scheme, etc) Total potential savings is a simple net figure derived from the potential savings and costs.
