London Wider Waste Strategy - London - Greater London Authority

visit and review specific pages. A recent survey of the registered users was positive and
the website has been recently upgraded to include new EU standards and purchase
orders etc. AggRegain did also explain that the main function of their tool is as a
specifier, and to provide information on case studies, rather than to act as a trading
tool.
5.54. Whilst consulting with construction and demolition contractors, they were asked if they
use tools such as the ones detailed above. All demolition contractors confirmed that
they did not use any of the waste exchange and similar tools. Only one environmental
manager of a construction site responded positively when information on these websites
was distributed amongst sub-contractors. In at least some cases, it is anticipated that
the above sites are too much of a niche market (e.g. fireplaces, interior doors, etc.) or
too small in scale to be of interest to large demolition companies.
5.55. Many of the demolition contractors were also owners of their own treatment facilities
and they use their own facilities where this is practical and feasible in financial terms.
Larger demolition contractors also try and programme in works so that there is a degree
of synergy between sites, for example using the waste from one site on another, or they
transfer waste from a smaller site to be treated at a larger site. It was understood from
discussions that in situations where contractors work remotely from their home area, the
network of associates and contacts available through the supply-chain is used to
identify the locations of facilities. This informal network approach to identifying outlets
for reuse and recycling appears to work well. On the other hand, if there is a supply
problem, contractors will get in touch with the large waste management companies and
pay the premium associated with dealing with them. In summary, a good quantity
surveyor working for a construction and/or demolition contractor will be able to tap into
an extensive network of information and contacts within the industry, and this will be
translated through to winning jobs at the best price, partially based on locating the
destination and source of waste materials.
Recommendation 49: It is recommended that the promotion of waste exchanges for
C&D waste should not be a priority in London at this point in time.
5.56. New and emerging tools to assist best practice with regards to construction and
demolition waste are in the form of demolition audits. One such audit under
development is the Demolition Protocol, published for consultation in November 2003.
This project was funded in the first stage by ICE, London Remade and EnviroCentre, and
in the second stage by WRAP. Discussions with the author of this report revealed that
the protocol had been viewed positively following preliminary consultation, with the
London Borough of Brent having already adopted the Protocol. A consultation
document has been issued, following a re-drafting exercise, and is in the process of
informing the final policy. The demolition of Wembley Stadium is currently being used
as a showcase/case study event for the Demolition Protocol with more events planned
over the next one to two years to promote its adoption.
5.57. The Demolition Protocol has the key aim of encouraging the planning system at local
and national levels to require more efficient use of resources in relation to demolition
contracts and new builds. The Protocol is promoted as a resource efficiency model to
show how demolition materials can be considered as a high value material in new build.
It presents the components of Demolition Recovery Index (DRI) and New Build
Recovery Index (NBRI). The DRI describes potential efficiencies for materials recovery
from demolition while the NBRI covers the potential percentage and quantity of
recovered materials that could be specified in new build. These measures facilitate more
