1 Site Waste Management Plans and the Code Dr Mervyn Jones, WRAP

2 WRAPs seven programmes WRAPs construction focus: Waste minimisation and management Materials recycling Procurement - (Recycled Content)

3 Materials resource efficiency Overall material consumption by construction industry (>400 Mt per year) M tonnes Quantity of construction and demolition waste generated (~100 Mt per year inerts) Waste construction materials that are recycled / re-used (~60 Mt per year) Overall waste generated (>150 Mt per year) controlled waste (~20 Mt per year)

4 Materials efficiency as part of sustainable construction Sustainability goals EnergyMaterialsWater Waste avoidance and minimisation Segregate, recover, reclaim and recycle Return surplus materials Specification of materials with low enviro. impact Use local C&D waste / reclaimed products Use less material Material selection Waste management Minimising environmental damage Efficient use of finite natural materials Use products with higher recycled content Demolition Protocol DTI Site Waste Management Plans Green Guide Ecopoints RC Toolkit

5 Code for Sustainable Homes (2006) 'Where the site waste management plan includes procedures and commitments that minimise waste generated on site in accordance with WRAP/Envirowise guidance'

6 Waste Management Hierarchy Reduce the generation of waste Reuse materials for the same or a different purpose Recycle the materials to recover value Dispose, using the best practical environmental option

7 True Cost of Waste The original purchase price and transportation costs of the materials + The cost of their handling, storage, transport and disposal + The loss of income from not salvaging the materials e.g. 8 cu yd skip Skip hire£120 Labour to fill skip£163 Cost of materials put in skip£1095 TOTAL TRUE COST£1378 (Source: AMEC)

8 True cost of waste Extraction of raw material for block Energy for block manufacture Stored for transport Delivered to site Stored on site Delivered to point of fix Broken whilst being laid Taken to waste container Disposed of Embodied energy at all stages! Example – Concrete Block

9 Potential savings Case studies have shown savings of: 3% of build costs 20% of materials on site 0.2% of total project costs saved through segregation (Source: Taylor Woodrow)

10 Residential Waste Streams The top five waste streams for residential, in terms of arisings are: Concrete & bricks Packaging Timber Plasterboard Miscellaneous

11 Waste per average newbuild house Typical 80m 2 housing unit = 15.36m 3 waste Approx 5 skips 9.6 tonnes £6,715

12 Waste Segregation Basic waste segregation into: General Waste (Non-hazardous) Inert Waste Mixed Metals (+ Hazardous waste separated out)

13 £90 £0 £90 £258 £90

14 Waste Segregation Housing development (30 skips /week): Mixed waste system =£4,970 Segregated waste =£1,935 Ca 60% saving

15 SWMP format 3 elements: Guidance Checklist (35 questions) Data recording sheet Guidance covers: Waste and legislation Duty of care Waste minimisation Training materials Reporting requirements

16 Message of SWMP Pre design stages Part of early project planning process as a framework introducing other tool & requirements such as demolition protocol, duty of care etc Design stages The design is a key factor in influencing waste arising during construction. Encourage design team to reduce waste at source. Construction stages Implement on site at all levels of construction activity. Communication and training to all site staff, where necessary.

17 Site Waste Management Plans: Current Practice Activity not carried out Activity carried out occasionally or at low level Activity carried out thoroughly on all sites

18 Housing Sector SWMP Support Sector specific suite of tools, requirements and guidance Provides model templates, requirements and clauses for incorporating into new and existing SWMPs based on: Standard practice Good practice Best practice

19 Housing Sector SWMP Support Specific elements include: Guidance for commissioning clients and housebuilders Template for developing a waste strategy Model clauses for Trade contractors Waste service providers Requirements for good and best practice implementation of SWMPs
