Waste management
is a key part of many of our operations from the office through
to the building and facilities management sites.
The use of resources, and the
generation and disposal of waste materials are key areas of
concern for Carillion and the Construction to Services Industry.
The Construction Industry alone is responsible for 70 million
tonnes of waste per year and it is estimated that this includes
13 million tonnes from unused materials.
Our control of resources and
waste will in part be achieved by implementation of the fundamental
steps involved in the waste hierarchy, Reduce, Reuse and Recycle,
as detailed in the diagram below.
Carillion is committed to greatly
reducing the amount of waste materials that it generates.
This will in part be achieved by the following;
Objective (2002-2003) - Reduce
waste production across Carillion
Target (2002) - Produce guidance
for the development of waste management plans to enable two
sites per Business Group and four major offices to have commenced
adoption of a plan by year-end.
2001 saw the establishment of
a waste
recycling scheme in our Head Office facilities.
In order to decrease the amount of waste sent to landfill
due to our office activities the following wastes were recycled
by our Head Office Facilities:
25.85 kg of
paper
160 lamps
291 toner
cartridges
17 sacks of
disposable cups
11 sacks of
drinking cans
This is the first year of the
recycling initiative and it is hoped that during 2002 more
materials will be recycled and a more detailed analysis of
the information will be undertaken.
Our office activities generate
waste, however, when compared to our on-site and facilities
management activities these levels are of a lesser magnitude.
Waste generation at site level is an area in which we are
continuing to improve our management and understanding. For
example, the first detailed study of waste patterns during
construction was undertaken at the Dartford and Gravesham
Hospital Contract. This provided figures on the level and
type of waste generated throughout the project lifecycle.
When work started on the Princess Margaret Hospital in Swindon,
a target to reduce waste levels to 50% of those generated
at Dartford was set. The graph below indicates the level of
achievement to date.
We have demonstrated our improved
understanding of waste management by comparing the two contracts
rather than year on year reductions for individual projects.
This is because levels of waste generated over a project lifetime
will change depending on the activities on site and the project
programme. Therefore, to compare the waste generation figures
in 2001 to those in 2000 for a single project would not provide
an accurate representation of the reductions achieved.
As the diagram indicates, the
Princess Margaret Hospital Contract is more than achieving
its target.
We have been able to utilise
our design expertise to help the government meet its target
of utilising 10% of electricity from a renewable source by
2020 by designing and constructing Waste
to Energy Plants. Crown House Engineering has designed
and installed Landfill Gas Fuelled Power Generation Plants
which convert landfill gas into electricity, which is then
sold onto the National Grid. To date the plants have generated
over 30MW. This reduces the use of fuel (a natural resource)
and ensures the maximum usefulness is captured from waste
that is disposed of to landfill sites.
Our procurement department reviewed
the supply chain control for procurement of waste services
that is in operation throughout the group. This highlighted
that the control over procurement of waste services needs
to be strengthened throughout the group.

minimisation;
