Agenda

WRAP’s vision is a world without waste, where resources are used sustainably.

We help businesses, individuals and communities reap the benefits of reducing waste, developing sustainable products and using resources in an efficient way.

About WRAP

To reduce the carbon impact of materials and water use in the built environment by mainstreaming resource efficiency in the design and construction of new buildings, infrastructure, and refurbishment projects.

What is Resource Efficiency?

Energy Water

Operational Impacts

Life-span

Recycled Content

End of Life

Material Quantity

Scarcity Wastage

Embodied Impacts

Waste hierarchy

Re-use – to use something again for the same purpose

Recycle – to process (waste) materials to make into new materials or as part of a new product.

Benefits

Often cheaper than virgin/recycled alternative

CO2 savings

Reduced raw material use

Moves up the waste hierarchy

Diverts waste from landfill

What is re-use?

Demolition/excavation stages

Refurbishment

On-site re-use

Off-site re-use

Cleaning and resale (as re-used product)

Re-use in construction

1998 - 2,967,000 tonnes reclaimed

2007 - 2,233,000 reclaimed

Why has there been a decrease?

Overview of re-use in construction

Woolwich SLAM (Single Living Accommodation Modernisation)

Re-use of aggregate, steel work, brick, doors, sanitaryware.

Re-use in construction – case study

3,500 tonnes of aggregate re-used

Saved between £26,500 and £42,000

350 lorry movements and 11 tonnes of vehicle CO2 emissions.

290 tonnes of doors

380 m2 - composite brick paving

Saved 14 t CO2 and £8 - £11000

Steel - fire escapes, radiators and stair treads (70t CO2)

Moss Side Regeneration, Manchester

Re-use of variety of materials – roof slate, window sills, timber joists, bricks

Bricks – 480m3 / 576 tonnes of bricks salvaged for reuse

Re-using 1,000 bricks: 800kg CO2/kg.

Re-use in construction – case study

Site Swap Shop

Free of charge between sites rather than purchasing new materials – the only cost incurred is transportation.

Examples drainage at Bamford Power station saved £8500 less £50 extra transport cost

Also saved >19t of CO2

South East Electricity Substation Alliance

Launched September 2010

Covers actions for:

Carpets/carpet tiles

Resilient flooring

Hard flooring

Resin flooring

Why?

600kt of flooring waste each year

2% recycled

Costs industry over £45 million

Flooring – A Resource Efficiency Action Plan

First years progress

Carpets

60 small scale collection trials

16.5% carpet diverted from landfill

32 000 tonnes recycled/reused

34 000 tonnes sent for Energy recovery

Manufacturers diverting 85% of carpet waste from landfill (6000 tonnes)

Flooring – A Resource Efficiency Action Plan

First years progress

Carpet tiles

Manufacturers doing trials on increasing recycled content and recyclability of carpet tiles

Refurbish / reuse 800k carpet tiles in 2011 (86% increase from 2010)

Increased outlets for Energy from Waste of carpet tiles.

Carpet Re-use market research and strategy report produced.

Flooring – A Resource Efficiency Action Plan

Typical cost

Re-use within organisation free

Purchase re-use tiles externally £0.50p per tile

Buying new £2.00 per tile

800 000 reused in 2011 would save £1.50 per tile of £1.2 million

Carpet Tile re-use

Abingdon Flooring

Re-use of Packaging

Recently acquired carpet tiles warehouse

Will send carpet tiles for re-use

Quadrant

Take back of any carpet tiles at fit-out

Social enterprise scheme

Usable carpet is given a useful second life

within third sector and deserving communities.

Re-use of Carpet Tiles

Forbo

22,000 tonnes diverted since 2001.

Benefits individuals, communities

and the environment.
