Along with engaging our suppliers to procure more responsibly sourced materials, we also want to ensure our waste contractors maximise opportunities to reuse and recycle the waste generated by our work.
Willmott Dixon has a prescribed system to assess and audit the waste contractors we appoint. We consider their operations and segregation capabilities. We ensure they meet our data return requirements. We check their documentation for duty of care compliance. We view working conditions for their employees.
All our waste contractors must complete a pre-qualification questionnaire to assess that they meet our standards, before they can become approved and listed within our Supply Chain System. We carry out a detailed on-site audit on their premises before they can remove waste from our projects.
We work with waste contractors who report their performance in accordance with PAS 402 (a specification for performance reporting for waste management organisations) in accordance with our Sustainable Procurement Policy.
In 2012 we worked with industry bodies to encourage a greater number of waste contractors to adopt the standard across England and Wales.
We worked with Kingspan Insulation on a trial takeback scheme at our Landau Forte Academy project in Tamworth. During the trial 230kg of insulation material was returned to Kingspan for closed-loop recycling. The scheme was a success: it cost the same as it would have done to pay a traditional waste management company to remove an equivalent amount of waste. Now this takeback scheme is available on all Willmott Dixon projects. We are also engaging with a number manufacturers and suppliers to develop new takeback schemes for other materials.
Karen Jones, Business Development Manager at Kingspan, said: “By working with Kingspan to help develop takeback scheme, Willmott Dixon not only reduces the quantity of insulation waste it sends to landfill, but also promotes the benefits of the scheme across the industry.”

Engaging the Supply Chain
High performance from our supply chain is critical if we are to achieve the challenging sustainability targets we have set ourselves. So we are providing support and guidance to our suppliers to help them implement environmental management systems (EMS). Possession of an Environmental Management System is just one of the requirements set out in our Sustainable Procurement Policy.
In 2012 we wrote to our entire Category A supply chain manufacturers and asked for details of any takeback schemes they operate. The resulting list provides guidance to design teams on materials where ‘closed loop’ takeback schemes are available, and to project teams on which products and materials they can send directly back to manufacturers. A suite of toolbox talks, posters and guidance notes are available within Willmott Dixon’s Environmental Management System, clearly signposted within the Site Waste Management Plan.
In addition, Willmott Dixon is also a lead partner in the establishment of a ‘Supply Chain Sustainability School’ – a virtual learning environment that aims to help construction suppliers and sub-contractors develop their sustainability knowledge and competence: http://www.supplychainschool.co.uk/
The School provides our suppliers with practical, free support which includes a prioritised action plan and an excellent range of free tools, e-learning and sustainability training, delivered by an independent third party, Action Sustainability. This ensures that clients can trust that all the results and information provided to develop client action plans will remain completely confidential. This commitment is enshrined in a Code of Ethics, signed by all the School’s partners – and is a central principal of the School.
