• TOTAL = 31.8 million tonnes


Demolition figures

• 94% of inert and non-hazardous waste reused/recycled

• 6% is hazardous waste – of which most will be landfilled.


Pre-demolition audit figures


How does it all add up?

2008 Million tonnes (est)

New build 12.9

Refurbishment 10.9

Demolition 32.7

Excavation 53.5

TOTAL 110.0


Reclamation figures

1998

• Total mass = 363 million tonnes

• Total recycled/secondary mass = 65 million tonnes (or 18%)

• Total reclaimed mass = 3 million tonnes (or 0.8%)

2005

•Total mass = 376 million tonnes

•Total recycled/secondary mass = 80 million tonnes (or 21%)

The NFDC Commitment and Action Plan

Howard Button, Chief Executive

25th March 2010

Introduction to NFDC

Dedicated to:

• To a continual improvement of the demolition industry for the benefit of its members, customers, and the general public through training, monitoring and policing of best practices;

• To enhanced flow on information and discussion between the demolition industry and Government, trade and technical organisations; and customers for the betterment of the industry at large

• To raising the profile of the demolition industry to ensure that it receives due recognition for its commitment to training, health and safety, and the improved working conditions it affords its members and their employees.

NFDC: what we do

• Training (National Demolition Training Group)

• Specialist advice

• Information

• Work with Government and other stakeholders

NFDC and demolition waste

• We already do a very good job !

• We have high (over 90%) recycling rates….

• But its not always easy, issues include:

– Time and client‟s awareness

– Products/systems harder to recycle

– Health and safety considerations

– Markets

– Legislation

Background

The target

„The target is to divert at least 90% of non-hazardous demolition waste

arisings from landfill annually. This will be reviewed in 2011.‟

Actions

• Action plan developed

• Support from BRE/CRWP

• Key issues that the demolition industry faces both now and in the future that may affect resource efficiency

• Need to work in partnership with the construction supply chain – we can only influence certain issues

Action 1: Measurement

Establish measurement and reporting system

• Use NFDC annual returns of members

• SWMPs and company reporting (e.g. WRAP Reporting Portal)

Annual Return Form

Action 2: Sign up

Sign up and encourage members to sign up to WRAP‟s ½ waste to landfill commitment

• We have already signed up and a number of members have

Action 3: Environmental thinking

Consider our environmental impacts

• In the future, environment will be important as cost

• Consider life cycle assessment in managing demolition waste including transportation

• Environmental impact of our operations

• Work with the EA

• For example – crushing on site reduces our transport impact

NFDC Environmental Policy

Action 4: Training, guidance and awareness

• Part of NDTG

• Waste will feature as part of the 6 day managers NVQ level 4 course

• Visit to crushing facility and BRE‟s Innovation Park

• Best practice for SWMPs

Provide appropriate training and guidance and to our members

Action 5: Client awareness

• Key issue often is not enough time !

• Work with clients to get our message across

• Use existing guidance

Work with clients to increase their awareness of our needs

Action 6: Recoverability of products

• More innovative construction products being used but can cause an issue at end of life

• Feedback to product designers and specifiers

• Work with key stakeholders in developing a research programme

• Design for deconstruction

Work with key stakeholders to improve recoverability of products and develop new ways of working

Action 7: Encourage reuse

• Work closely with the reclamation industry

• Encourage reuse where possible

• Developed a reclamation salvage operators card

Encourage the reuse/salvage of suitable products

Reclamation card

Action 8: Policy/legislation

• Work closely with Defra and EA

• Work with the Strategic Forum and UK Contractors Group

• Look at upcoming legislation

• Gather evidence from members

We will input in to appropriate legislation and policy

Action 9: Focus on material specific waste streams

• Provide a focus on wastes that may cause issues e.g. hazardous

• Work with other stakeholders e.g. plasterboard voluntary agreement and flooring

Where appropriate, provide input and focus to specific material streams

Action 10: Our own processes

• Report quarterly on action plan as part of the National Council Committee

• Define responsibility

• Look at our site audits and other areas

Embed within our own processes

Next steps

• Publishing of target and action plan

• Continue our work in this area !

Thank you

Howard Button

Managing Waste , the Environment and Legislation

A Contractors View

ISO 14001:2004 Preliminary Environmental Review

1. Decide which of your activities you wish to register

2. Carry out your own audit and note;

a. Legal non-compliances

b. Potential pollution causes etc

c. Environmental aspects and impacts

ISO 14001:20043. Document your significant aspects

4. Make recommendations for improvement

5. Set targets and objectives for;

a. Short term

b. Medium term

c. Long term

6. Carry out a cost analysis including punitive measure costs

ISO 14001:2004

7. Take photos of the site areas as it is now

8. Create a reference document ( consider producing a formal environmental manual – though not absolutely necessary )

9. Work towards improvement

10. Register for external auditing and accreditation

Site Waste Management Plans Statutory requirement from April 2008

Their aim is for;

greater resource efficiency in the construction sector

improved re-use and recycling rates

a reduction in fly-tipping

a reduction in site accidents.

Site Waste Management PlansWho are they likely to affect;

anyone planning a construction project costing more than £300,000

any construction project clients or architects that produce, manage or dispose of waste

suppliers to the construction industry

environmental regulators, ie local authorities and the Environment Agency.

Your plan should therefore;

Site Waste Management Plans identify the different types of waste that will be

produced by the project, and note any changes in the design and materials specification that seek to minimise this waste

consider how to re-use, recycle or recover the different wastes produced by the project

require the company to demonstrate that it is complying with the duty of care regime

record the quantities of waste produced.

Site Waste Management Plans

The intention of the regulation is to make one person responsible for the plan

It should be a standard plan for projects of £300,000 and detailed for projects over £500,000

Failure to apply the principle of SWMP’s will mean fiscal and punitive punishment

The EA are to police the process

The construction industry‟s forum on resource efficiency and waste reduction


Content

• Pre-demolition audits

• Case studies


• BREEAM and Code for Sustainable Homes

• Reducing environmental impact


Life Cycle of Buildings

• Sometimes some buildings have to be

demolished

Built in 1968’s

Demolished 2007

Hackney, East London

Built in 1859, Philip Webb /

William Morris (Arts & Crafts)

Still standing

Bexleyheath, SE

Built in 1968,

Demolished in 2008

London Borough of Hackney


Pre-demolition audits. What are they for?

• Taking stock of what is in the building

• Quantifying Key Demolition products

• Pre-plan segregation and recovery activities prior to work

• Can be done well before demolition work starts (6 months)

• Enables the setting of targets for use in contracts / planning

• Knowing where the materials will end up / how they were used

• Maximising potential for using materials

- Salvage

- Recycle on site / reuse in new development

- Recycle off site / proximity principle

- Stockpile recycled material to use in a new phase of development


Benefits of Pre-demolition audits

• To realise financial benefits from recovering materials

• To quantify the environmental rewards of material recovery

• Show commitment from the client towards resource efficiency

• Feeds into ICE Demolition

Protocol and SWMPs

• BREEAM (credits)


Link with SWMP

• SWMP legally binding since April 2008 in England.

• Legal requirement for both construction and demolition projects costing £300,000 or above

• The pre-demolition audit provides information on types and amounts of materials and waste management options

• This information can be used as part of the SWMP required for demolition work

• On project completion the actual quantities of materials removed can be measured against the predicted quantities

• Gives a clear account and audit trail for demolition materials


Pre-demolition Audit

Stages include:

• Analyse blueprints, sectional &

engineering drawings

• Proposed development plans

•Site visits (surveyor)

• Nature of buildings and Key

Demolition Products:

- Quality

- Condition

- Fixture

•Establish indicative recovery targets


Reclamation valuation / Environmental

quantification

•12 environmental impacts = Ecopoint

•100 Ecopoint = overall impact of 1 Citizen over 1 year

•Savings of CO2

•Reclamation expertise

•Site visits to visualise quality, condition & fixture

•Variable valuations:

• Sold to trade, own dismantling

• Sold to trade at the gate

• Sold on Salvoweb

• Reuse value on site

Climate Change Acid Deposition Ozone Depletion

Human Toxicity to Air Low Level Ozone Creation Fossil Fuel Depletion

Human Toxicity to Water Ecotoxicity to Water Eutrophication

Minerals Extraction Water Extraction Waste Disposal


Examples of results


Example of results


Key considerations

• Time needs to be planned in

• Reclamation can require deconstruction (which may take time and money)

• Reclamation can rely on local markets and may require storage of products

• Include waste recovery targets as part of the procurement process

• Quality of demolition waste onsite (e.g. contamination)

• Potential to reuse on site (need to link back to design phase)

• Difficult materials entering the waste stream – hard to recycle


Case Study:

London Borough of Hackney

• Rebuilding of social housing –Kings Crescent Estate

• Site is located in Stoke Newington - 2.53 ha

• The estate was constructed in 1968 and comprises of 404 units

• The findings and recommendation was included in demolition Contract Documentation

• Demolition contractor had to meet minimum 85% recycling target

• Pre-dem audit estimated amount of demolition arisings was approx 3,500 tonnes

• Recycling the bricks and concrete on site saved 178 number of lorry movements = 17 tonnes CO2

• Savings on virgin material used = 2,680 tonnes

• Potential financial saving by reusing the aggregates on site as backfill and landscaping materials = £12,060

• Off site recycling of metals worth

= £7,500

London Borough of Hackney:

Savings Made


Case study: Pre-refurbishment Audit –

University of Reading

• Refurbishment of artist studios

• Pre-refurbishment audit as part of SE CoRE

• Built in 1904 –University of Reading

• 82% of material were reclaimed

• Slate roof tiles (15 tonnes),

• cast iron school radiators (10 tonnes),

• timber doors (0.7 tonnes)

• Approximate savings £20,000


Croyland Swimming Pool,

Wellinborough


Benefits of Pre-demolition Audits

•Early identification of materials encased in the buildings – more time to

find outlets for reuse / recycling

•Optimises transport movement / resource planning early on / saving on

carbon impact

•Contributes towards fulfilling SWMP requirements for forecasting the

quantity of demolition wastes arising

•Provides documentary evidence on measuring demolition arisings

•Salvageable items replace new products / promotes the value of heritage

•Savings on embodied energy

•Provides good PR


Planning requirements

• Planning authorities

starting to ask for SWMPs

and pre-demolition audits

as part of planning

applications

• Supplementary Planning

Guidance

• Section 106 requirements


• Widely used:• over 110,000 buildings assessed

• nearly three quarters of a million registered

• Respected and replicated throughout the world

• Developed with industry

• Independent governance.

• Regularly updated to ensure best

practice.

• Increasingly used within Europe and internationally.

BREEAM: Waste

• A pre-demolition must be carried out to maximise recovery

• Must be referenced in the SWMP and cover ID of materials and

applications

• Demolition target – 90% (weight); 80% (volume) diverted from

landfill (non-hazardous)

• Exemplary demolition target – 95% (weight); 85% (volume)

diveretd from landfill (non-hazardous)


BREEAM: Other Credits related to

demolition

• Use of reclaimed materials also features in the „Responsible

Sourcing section‟


Environmental Impact

• ‘If the demolition industry relies only on

following the ICE demolition protocol it runs

the risk of using recycling rates as the only

sustainability indicator, which is an

unbalanced approach to integrating

sustainability into demolition and subsequent

construction works (Bjerregaard, 2008 )
