Halving Waste to Landfill Richard Buckingham Head of Construction & Refurbishment WRAP
Commitment made by industry Data on performance was
unreliable Better levels of data were required Landfill levels could likely be
reduced Landfill levels should be reduced
Why Halving Waste to Landfill ?
A Voluntary Agreement
WRAP set up a Voluntary Agreement to deliver the HWTL commitment
Supported by the Strategic Forum for Construction and Government
Steering group of WRAP, Government Agencies and Industry
Open to all actors in the construction supply chain
Branding, marketing and support
Why Signatories Participated
Costs Achieve real cost
reductions
Legislation Achieve legal compliance
Environment Enable clear environmental
benefits
Reputation Achieve clear market
recognition
What is the total cost of waste?
Raw material wastage
Waste collection and transport
Quality losses e.g. rejects
Energy, water and other material losses
Handling and storing waste
Discharge effluent or air emissions
Cost of protective equipment
Workplace monitoring
Spillages, leaks and contamination
Insurance
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
Waste disposal costs are only the tip of the iceberg……
e.g. For 8 cu yd skip:
Skip hire £85
Labour to fill skip £163
Cost of materials put in skip £1095
TOTAL TRUE COST £1343

Opportunities to reduce costs
Cash savings
Waste disposal costs
Materials purchase costs
Avoided purchase
Lower wastage
allowances
Less waste in total
Lower skip rates for
higher value materials
System costs
Lower life-cycle
costs
e.g. D&E reuse,
in-situ
stabilisation
e.g. design,
ordering,
logistics
e.g. OSC,
design for
refurbishment
e.g. on-site
segregation,
efficient MRF
“We commit to play our part in halving the amount of construction,
demolition and excavation waste going to landfill by 2012. We will
work to adopt and implement standards for good practice in reducing
waste, recycling more, and increasing the use of recycled and
recovered materials.
We will:
pursue a reduction in waste to landfill;
embed a specific target within our corporate policy and processes;
set corresponding requirements in procurement;
measure performance relative to a baseline; and
report annually on performance.”

Client & Contractor Signatory Requirements
“We will:
set a target
embed the target within corporate policy and
processes
set requirements in project procurement
measure performance relative to a corporate
baseline
report annually on overall corporate performance.”
Designer & Consultant Signatory Requirements
“We will:
create design solutions that minimise waste and use resources efficiently;
identify for clients and contractors the best opportunities to reduce waste and use more recovered material;
measure the potential improvement at project level;
support our teams in broadening their knowledge of resource efficient design; and
report annually on overall corporate performance.”
With respect to the project objective to reduce waste and use materials efficiently, and specifically to support XXXXXXX Group plc corporate objective to reduce waste to landfill by 70% by 2012 from a 2008 baseline, the Contractor shall be required to:
• implement Site Waste Management Plans throughout the contract period that comply with regulatory requirements (where applicable) and include in such Plans project-specific targets for waste recovery and reused and recycled content (below) and for waste reduction;
• measure and report progress against the corporate KPIs for the quantity of waste produced and the quantity of waste sent to landfill (measured in tonnes per £100k construction value) using the WRAP Waste to Landfill Reporting Portal and guidance;
• aim to generate less construction waste than 7 tonnes per £100k construction value;
• recover at least 70% of construction materials waste, and aim to exceed 85%
Main Construction Contract (general conditions) The Contractor and his supply chain shall carry out and complete the works in compliance with the Employer’s objectives for reducing, reusing and recovering waste materials. Preliminaries These clauses set out the contractor’s responsibilities for achieving and reporting waste outcomes.
