Materials with recycled content
A two thirds reduction in consumption of fossil fuels and virgin materials is needed to achieve a sustainable and globally equitable level

WRAP’s construction focus
To accelerate the transition of construction waste to a useful, recycled material
Waste minimisation and management
Reprocessing C&D wastes
Procurement of recycled content

True cost of waste
Example - 8 cu yd skip
Skip hire £85
Labour to fill skip £163
Cost of materials put in skip £1095
TOTAL TRUE COST £1343

Materials resource efficiency on site
Simple principles:
Re-measure – 5-10% typical wastage
Reject & return – poor specifications & take-back schemes
Reduce – design out waste to start with
Re-use – formwork, site fixtures, reclaimed materials
Recycle – specify recycled and upcycle
Review – ensure procedures are up to date
Training & awareness / Waste Aware Construction

How can SWMPs help?
Manage risks relating to materials and waste on your site
Deal with queries from regulators
Demonstrate to clients how you manage waste, and how you reduce costs and risks to them
Meet the requirements of quality and environmental systems
Comply with likely future contractual requirements
Save money!

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

SWMP stages
9 Key steps:
Step 1 – Identify who is responsible for producing the SWMP
Step 2 – Identify the types and quantities of waste that will be produced at all stages of the work programme/plan.
Step 3 – Identify waste management options (waste hierarchy - on- and off-site options)
Step 4 – Identify waste management sites and registered waste contractors - compliance with Duty of Care.
![Page 14: Materials & Recycling Promoting Resource Efficiency in Construction South Ayrshire Sustainability Forum John Forbes – Scotland Manager. WRAP.](https://reader035.fdocuments.us/reader035/viewer/2022062322/56649cb55503460f94978e6f/html5/thumbnails/14.jpg)
SWMP stages - contd
Step 5 - Training of in-house and sub-contract staff
Step 6 – Plan for efficient materials and waste handling & develop targets
Step 7 – Measure waste quantities and what types of waste
Step 8 – Monitor the implementation of the SWMP
Step 9 – Review the SWMP at the end of the project and identify learning for next time.

The Protocol & demolition (or refurbishment)
• Pre-demolition audit
• Material segregation / recovery methodology
• Recovery target set
• Evidence provided of compliance with target

The Technical Potential
Many mainstream products already include recycled content
A range of products offer above-average recycled content at no extra cost
The potential for diversion from landfill is substantial
