Enabling Zero Waste
Enabling Zero Waste (EZW) is a CEW initiative designed to work with the construction industry to provide practical, positive and active intervention via professional waste management solutions to assist in enabling zero waste.
The initiative offers collaboration at all stages of the design, development and construction of sites providing mentoring and practical operational assistance, enabling a reduction in waste arisings and producing a detailed evidence base to demonstrate the achievability of zero waste to landfill.
The scheme encompasses problem solving, overcoming behavioural, cultural, practical and where possible, technical obstacles to achieve zero waste to landfill with a circular economy approach.
The objectives of EZW are:
- to establish if zero waste can be achieved
- to identify any constraints and/or barriers to achieving zero waste
- to inform future strategies for industry waste reduction
- to benchmark current industry performance
- to achieve Towards Zero Waste through the application of Wellbeing of Future Generations (WFG) principles
Our targets for EZW are as follows:
|Waste prevented per project total||8,000 tonnes
Year 1 Q3/Q4 2,000 tonnes
|Waste reused per project total||5,000 tonnes
Year 1 Q3/Q4 1,000 tonnes
|Waste recycled per project total||3,500 tonnes
|Year 1 Q3/Q4 500 tonnes
Year 2 1,500 tonnes
Year 3 1,500 tonnes
|Cost savings per project total||£22,500 tonnes
Year 1 Q3/Q4 £2,500
Launched in 2014, CEW has been working alongside four live construction sites to explore the achievability of zero waste.

Enabling Zero Waste Phase 2
Sea Defence Works West Rhyl (Coatech)
Coatech installed approximately 4,500m2 of resin bonded surfacing as part of the continued development of the sea defence and promenade on Rhyl seafront.
Some of the waste management successes of the project included;
Work on the West Rhyl Sea Defence project has been undertaken by Coatech a specialist contractor and applicator of all types of resin. Coatech is working in partnership with CEW and the Enabling Zero Waste initiative to avert waste generated during the surface dressing of the promenade walkway.
- A committed and enthusiastic site team
- Segregation of materials
- Approximately nine tonnes of unbound aggregate prevented from being downgraded through the segregation of the aggregate sweepings
- Material reuse
- Small quantities of waste sent to landfill
WRW Aberystwyth Fire Station
WRW is working in collaboration with Constructing Excellence in Wales and the Enabling Zero Waste project to avert waste generated during the demolition and new build of Aberystwyth Fire Station. As part of the Enabling Zero Waste project the particular focus will be to avert waste generated from demolition and to ascertain whether an unusual design results in the unnecessary generation of waste.
Enabling Zero Waste Phase 3
Torfaen Schools (Willmott Dixon & Torfaen County Borough Council)
Constructing Excellence in Wales (CEW) is working with Willmott Dixon Construction Limited and Torfaen County Borough Council as part of the Enabling Zero Waste initiative.
Willmott Dixon has started the construction of three new primary schools in Torfaen. As part of the £15.6million project Willmott Dixon will build:
- Blenheim Road Community Primary School – replacement on the current site, 315 pupil places
- Ysgol Panteg – replacement of the Griffithstown and Kemys Fawr sites on a new site on Station Road, 420 pupil places
- Llantarnam Community Primary School – replacement on the site of Llantarnam secondary school, 315 pupil places
All three primary schools are based on the same design, giving Blenheim Road and Llantarnam the potential to expand to 420 places in the future. It offers the Enabling Zero Waste (EZW) team at CEW a unique opportunity to directly compare waste production, management practices and site behaviours. The EZW team will work in collaboration with Willmott Dixon and their supply chain throughout construction to help identify any opportunities or solutions to reduce waste.
Loftus Garden Village (Lovell)
The Garden village is situated in the heart of Newport, previously occupied by the former Pirelli Cables factory. The project consists of a four phase plan with the construction of 250 homes for the Seren Group.
CEW will be working alongside Lovell to compare waste data across the phases and look to reduce waste arisings at every opportunity. Building Information Modelling (BIM) will also be used to examine the potential for visualisation, project management, clash detection, improved efficiencies and waste minimisation.
Enabling Zero Waste Phase 4
Willmott Dixon Construction Ltd. are constructing phase one of Menai Science Park, M-SParc. The 5,000m2, three storey BREEAM Excellent building will provide offices, laboratories and workshops for around 200 people. Working with the Enabling Zero Waste team Willmott Dixon are looking to prevent, reuse and recycle as much waste as possible.
• Design Review – to identify potential for resource efficiency
• Material Use – working with Bangor University to identify and develop solutions for problem wastes
• Supply Chain – liaising with suppliers to reduce packaging, or have it taken back
• Site Waste Management – suggesting different methods, data recording and analysis
• Canteen and Office Waste – collections to ensure 100% recovery
• M-SParc ‘Ignite’ – use of waste materials by local artists
Parc y Tywyn
Construction of the new Parc y Tywyn is underway. The project in Burry Port will provide a Passivhaus and BREEAM Excellent primary school to replace the existing Ysgol Gymraeg Parc y Tywyn.
The Dawnus team have been working with the Enabling Zero Waste team to look at how to best prevent, reuse and recycle waste on the Parc y Tywyn site. Efforts include;
• SMARTWaste training – this been given to help with recording waste data
• Canteen and office waste – separate collections have been arranged to avoiding comingling with construction waste
• Advice on site waste compound – fenced, locked, segregated and with skips away from the site boundary.
Pentrehafod Secondary School
Pentrehafod Secondary School is undergoing major refurbishment work which includes aspects of demolition, new build, extension and refurbishment. Morgan Sindall are undertaking the project to a two-year timetable with no decanting of pupils. The EZW team will offer waste management advice and support throughout the project, whilst encouraging a circular economy approach.
The Mill, Lovell
Lovell is working in partnership with Constructing Excellence in Wales. Lovell's second Enabling Zero Waste project is aiming to avert waste generated during the development of an 800 home urban village. As part of the Enabling Zero Waste project the particular focus will be establishing best practice in terms of trades, waste management, procurement and lessons learnt from work undertaken at Loftus Garden Village, Newport.
A £100 million flagship development covering 53 acres of inner city Cardiff, transforming the former papermill into a Urban Village with 800 homes for Tirion Group.
Excellent opportunity to minimise waste streams on a large project, compare waste data across the phases and look to reduce waste arisings at every opportunity.The development is expected to bring up to 1000 jobs during the construction.
The chosen schemes are supported with practical assistance on all aspects of waste management from concept to completion. This will provide the basis for identifying, managing and documenting each type of waste, the possible options and available solutions, together with finding the root cause.
Learning outcomes will be published throughout the duration of each of the live construction projects, with regular updates posted on our @EZWaste_Wales Twitter feed.
At the end of the Enabling Zero Waste initiative, full reports will be produced on the achievements, solutions and lessons learnt.
Angle Peninsula Primary School, WRW Construction
Enabling Zero Waste is under way at Angle Peninsula Primary School Pembrokeshire. A third EZW initiative for WRW, who is the appointed main contractor for the construction of the new school. WRW occupied the site early in October 2017 and anticipates completing the scheme towards the end of 2017.
The EZW team are reviewing possibilities of implementing material take back schemes and waste segregation best practices have been implemented to increase recycling rates and avoid waste sent to landfill. A canteen waste service has been provided on behalf of Pembrokeshire Council, offering a road side collection service for the duration of the project, preventing food and canteen waste from entering mixed waste skips, and helping to increase recycling rates.
WRW has improved their waste performance on each EZW project. A project update and best practices will be reported in due course.
Aberystwyth Innovation and Enterprise Campus
Aberystwyth University and AIEC Limited are working in partnership with Constructing Excellence in Wales to avert waste generated during the upcoming construction of the new Aberystwyth Innovation and Enterprise Campus at Aberystwyth University's Gogerddan site (www.aiec.wales). As part of Enabling Zero Waste, the AIEC project will focus on monitoring waste arising from different activities, identifying any problematic waste streams, establishing benchmarks upon which improvements can be made and identifying opportunities for solutions.
Aberystwyth Innovation and Enterprise Campus (AIEC) will provide world leading facilities and expertise for the agri-tech industry and the bio-science sector. Set between the Cambrian Mountains and the Irish Sea, this £40.5M campus will be a progressive environment to encourage business and academic collaboration to flourish. Aberystwyth Innovation and Enterprise Campus will offer a range of high quality facilities to support innovation, enabling commercial enterprises to grow, prosper and drive economic growth in the food & drink, bio-processing and biotechnology sectors throughout Wales and beyond.
Initiatives planned for the AIEC include:
- Innovation Zone
- Analytical Science Centre
- Future Food Centre
- Bio-refining Centre
- Seed Biobank and Processing Facility
Willmott Dixon Construction Ltd. are the chosen contractor for the scheme. Working with the Enabling Zero Waste team Willmott Dixon are looking to prevent, reuse and recycle as much waste as possible. As part of the EZW initiative CEW will:
- undertake a pre-demolition survey to identify opportunities for reuse/repurposing, material reuse/recycling of the elements identified for demolition.
- carry out a design review in terms of quantifying savings mae between the earlier scopingn site design and current design
- review the final design to examine the material choices with a view to identifying opportunities to increase waste prevented/minimisation, enhance resource efficiency and end of life benefits.
A final planning application for the Campus has submitted to Ceredigion County Council with a decision expected in the Spring of 2017. If planning permission is granted, construction is due to start mid-2017 and is expected to take two years to complete.
Building Information Modelling (BIM)
Building Information Modelling can be instrumental in waste minimisation and best practice. CEW has used Building Information Modelling (BIM) as part of Enabling Zero Waste in the following ways:
- To review the original design with the aim of designing out waste
- To establish whether design changes impact upon material usage and waste production, for example value engineering
- To provide a visual tool to demonstrate design changes, for example the incorporation of additional material, changes to a roof line to clients and regulators
- To develop practical solutions to help designers prevent and minimise waste on future projects
- To identify and prevent clashes from occurring
- To calculate the potential for saving resources by using BIM post design to identify possibilities of reducing waste generated from repetitive items and define processes for future projects
- To deconstruct a building to ascertain how much material could currently be reused and what changes would need to be made to the design in order to maximise the potential for material reuse at the end of the building’s life
- To provide a mechanism to easily identify hidden M&E
By using BIM in these ways we have realised material savings of over 4,600m3 and cost savings of over £96,000 as part of the construction and demolition waste programme, Enabling Zero Waste project.
