Outline
- Why Maximise Reuse?- Some Practical examples - Reuse organisations and CSR benefits
Key Learning: To maximise reuse, write reuse into the contract
Ecological Footprint by Country
UK
A Quick update of where we are now:
Resource use: links waste and climate impact
50% of impact is what we build and buy
Ecological Footprint of average UK resident: 5.45 Gha
CO2 emissions of average UK resident: 11.87 tonnes

What is Reuse and Recycling?Term Definition Examples
Prepare for Reuse(Reclaim)
To recover a product for reuse, originally destined to be a waste
De-nail timber beams.Clean bricks from demolition site
Reuse Reuse of product in original form with minimal reprocessing
Reuse reclaimed beamsBuild wall from reclaimed bricks.
Recycle Recover constituent materials of a product to remake into product of equivalent value
Wood goes to chipboard. Sub-base into aggregateGlass recycled into new glass productRecover
(Downcycle)Recycle product into something of lower grade, in material/economic value.
Wood chips go to energy plant or are compostedBrick or glass turned into aggregate
Reuse helps reduce shared impacts
Reduce Reuse Recycle
Less Stuff Use Again
Zero Waste
Focus on Consumers
Plan to share cuts across all sectors
Plan to reduce CO2 of Construction
Reuse Buildings

Why worry about Embodied Carbon?
Estimates that it is approximately• 1 tonne CO2/m2 office• 9,000 tonnes/km dual carriageway• 56 tonnesCO2/ave. new house (www.censa.org.uk)
• 25 million homes• 50% embodied carbon is to maintain what we already have in the UK
Products = 80% of Construction CO2
Taken from the Low Carbon Construction Innovation and Growth Team Final Report, 2010
Breakdown of construction sector
• Housing Construction 13.9%• Infrastructure 7.6%• Other New Work 30.9%New Construction = 52%
• Housing Repair and Maintenance 24%• Other Repair and Maintenace 24%Maintain/improve existing = 48%
Data: ONS, Construction, 2010

Why worry about Embodied Carbon?
Optimum Resource Use = Reuse?
Embodied carbon means rethinking waste
Case Study 1: Furniture Reuse

Case Study 1: Furniture Reuse
Case Study 1: Furniture Reuse
“Businesses that reuse office chairs and desks are saving over £14 million a year, as well as helping to reduce carbon emissions and increase jobs in the UK”, according to new research by WRAP (2011).
Case Study 1: Furniture Reuse
"Hundreds of community organisations across the country have for many years been quietly salvaging, restoring and redistributing discarded furniture and equipment to provide vital help to families and other people in need, creating employment and training thousands of volunteers in the process."
Reuse creates more jobs

Saves energy + waste
Less energy recovered. More waste.
Reuse cuts carbon emissions
Example: Wood Recycling Enterprise
Case Study 3: Timber Reuse

EfW+CHP ~ -138 EfW ~ +310 Landfill ~ +340
Data: David Weight, ICE Energy Journal, November 2011
Note: Unsustainable source = extra 5-6 tonnesCO2/tonne
Case Study 3: Timber Reuse
Less timber reused: a lost opportunity
•Much Less Reuse. The timber reused in UK fell by 250,000 tonnes in 10 years until 2007. (10 of 16Mt/year imported, 10% comes from outside EU).•Special. We burn elm floorboards we used to reuse, for which you cannot source new. •New enterprises not plugging the gap. 20+ wood recycling not-for-profit enterprises reuse 0.4% of this. •Wasted carbon. The carbon saved by reuse (reducing need for virgin timber) is over twice CO2 on saving from a energy-from-waste plant. CO2 for deforestation average 1tonneCO2/ tonne timber used globally.
Reclaimed timber
• Sourced from reclamation yards• Or taken directly out of demolition jobs• Or from refurbishment
Joists can be:• Reused as joists or• Milled into floorboards
Studwork: not structural or visible54km at BedZEDcarbon benefit, cost neutral
Even best sites have left overs…
New homes for product: Play Association Tower Hamlets, Hackney Children's Scrap project, Hawkwood Allotments, Selby Trust, Arcola Theatre…
Case Study 4: Refurbish + Construction Surplus
Recycling – maximise segregation
•target rate 100% segregation •venues: monthly reporting
Example: Olympics Media Hub
•96% segregation on-site•wheelie bins near workforce•workforce engaged / aware•carrot: logistics team incentive to segregate•stick: subcontractor penalty for cross-contamination
Reuse Onsite – Waste Segragation
on-site materials exchange facility to redistribute material that is suitable for reuse off site.…allow redistribution back around the site of materials suitable for reuse. …develop on site materials exchange facilitymetal off-cut bins to be inspected…for reusable material before being added to the metal recycling for off site removal.
One Example…
‘Arcola Theatre brings the very best of the worlds performing and visual arts to the people of the world living and working in London’ The Guardian
Reclaimed – other examples
Reuse: $ incentive + Community-led
New York – Broadway Musicals done with reuse!
M & E - overcome barriers
Barriers to Reuse
Lead in Creating Solutions
Time and Lack of commitment
Put in Contract
Lack of space and cost of land
Site (lots empty)
Labour Intensive Process
Skills, Training and Social Benefits
Can we fix it?
Yes We Can… in London
Centres to Reuse All Products
Mayor's Office Press Release "£8m to create UK’s first city-wide reuse and repair service." (May 2010)
Yes We Can… in London
Centres to Reuse All Products
Yes We Can… in London
Centres to Reuse All Products
• Bricks, blocks, Paving, flags• Plumbing, drainage• Timber, windows, doors• Paint/decorating supplies. fixing
• Save CO2 emissions embodied in products• Can be significant financial / carbon savings• Efficient Collection Service• Good CSR potential• Links to Trainee and Apprenticeship Schemes
Benefits: Better FM, lower environmental impact
Some Recommendations
• Create a FM 'procurement and reuse strategy' as well as saving on-site energy use. Focus on fixtures, fittings and refurb not just the weekly wastestream
• Use and reuse - via third-sector organisations for furniture and IT; - via exchanges (e.g. recipro) and wood recycling projects for refurbs.
