Why take action?
Reduce environmental burdens
 less waste to landfill
less site traffic
lower carbon footprint
Cut costs
lower tender prices if requirements
are set and waste reduction is planned
at an early stage
Maintain reputation
 demonstrate Corporate
Responsibility
 demonstrate efficiency and
sustainable procurement

SWMP Regulation (England)
Legal requirement on all projects in excess of £300k (increased
requirements for those in excess of £500k)
It should include:
 headline information about the project;
 the name of an individual responsible for waste;
 a forecast of the quantity of waste that will be generated;
 a set of clear actions to reduce waste, and to increase the level of
recycling;
 the end destination for each waste stream and the recovery rate that
will be achieved.
Skanska Bristol schools PFI
Cost of waste disposal:
 £42/t well segregated
 £238/t poorly segregated
Cost of waste:
 £274k estimated value of
materials wasted at one school

Overview of waste
forecasting
Benefits of waste forecasting

Estimating waste streams and allows you to identify:
– Opportunities to reduce wastage and save money
– Opportunities to segregate and reduce disposal costs
– Opportunities to increase recovery
Net Waste Tool
Users:
Design team – Quantity Surveyor
When:
RIBA stage C to E (or equivalent)
Inputs:
Basic cost plan data
Cost:
A few hours effort, depending on project size
Benefits:
Identify opportunities to reduce cost of waste
Identify opportunities to increase RC and re-use
Provide waste forecast data for the SWMP
Use results to demonstrate CSR
Example
The principal contractor used the Net Waste Tool to:
• forecast waste arisings
• understand the cost of waste
• set actions to reduce waste arisings
• increase the segregation and recovery of waste
Material selection – Tya, your original title was
Recycled content!
Inputs
Project details
(e.g. value)
Project
quantities
(e.g. floor area)
Programme
Choose component
specifications (e.g. 100m2 of
12mm plasterboard)
Upload actual
waste data postconstruction
Input options
OR enter quantity from cost
plan
Accept the Tool’s quantity
estimates (e.g. based on floor
area entered)
The objective is to produce a ‘best fit’ analysis using the data you have available
Outputs
Graphs showing results as you
work through the analysis
(baseline, good practice and
targeted)
Headline results:
- waste arisings
- waste to landfill
- cost of waste
- recycled content
- KPIs (improvement)

Quick Quiz
•
Does the NW Tool assess recycled content?
•
What other outputs does the Tool provide?
•
If you don’t have a cost plan, can you still use the Tool?
•
What did the Net Waste Tool used to be called?
•
Who should use the Tool and when?


Use your own project data or

SWMP Template - benefits






goes beyond compliance, so can be used for projects across the UK;
clear demonstration of compliance with the SWMP Regulations 2008;
Applicable to all sizes of project and all types of construction;
enable users to progress from Standard to Good and Best Practice
and demonstrate this;
data only has to be entered once and are then taken forward
automatically to subsequent Steps; and
Net Waste Tool waste forecast can be used in the SWMP Template.
Inputs and outputs
WRAP/Envirowise SWMP Template (v2.0)
Users:
Client & Principal Contractor
When:
As early in the project as possible
Inputs:
Waste forecasts
Actual waste arisings
Waste destinations
Cost:
A few hours, depending on project size
Benefits:
Meet the legal requirement (England only)
Identify Good & Best Practice opportunities
Assign responsibilities for waste management actions
Identify areas for improvement & lessons learned

SWMP Tracker
Aggregate and analyse data from multiple SWMPs:
1. upload SWMPs
2. select which SWMPs to aggregate
3. download an Excel based report
4. Send data directly to the Halving Waste to Landfill Reporting
Portal.

Insert a slide covering the reporting
portal – just a link to say where it is.
Hopefully most people will attend the
later session so no need to cover in any
detail.
