Kuusakoski Group today<br />
Founded by Donuard Kuschakoff in Vyborg in 1914 as<br />
Karjalan lumppu- ja romuliike<br />
Now Kuusakoski Group recycling <strong>and</strong> foundry businesses<br />
Leading industrial recycling company in northern Europe<br />
Forerunner in developing recycling technology<br />
One of the largest suppliers of recycled metals in the world<br />
New businesses:<br />

Demolition services<br />
• Services for companies, local authorities <strong>and</strong> consumers<br />
• Recovered materials refined primarily for industrial use<br />
• Group turnover 978 M€ <strong>and</strong> personnel 3200 in 2011<br />
• Operations in Finl<strong>and</strong>, Sweden, Denmark, United Kingdom,<br />
United States, Russia, Estonia, Latvia, Lithuania, Pol<strong>and</strong>,<br />

”Environmentally Sustainable Buildings: Challenges <strong>and</strong> Policies” (OECD 2003)<br />
http://www.oecd.org/document/28/0,3343,en_2649_34289_37251036_1_1_1_1,00.html<br />
“It is important to note that a sharp<br />
increase in C&DW is predicted for this<br />
century. /…/<br />
As it is difficult to reduce the quantity<br />
of materials used for buildings,<br />
promoting the reuse <strong>and</strong> recycling of<br />
building materials <strong>and</strong> components<br />
could be emphasised for waste<br />
minimisation in this sector.” (p. 27)<br />
In other words, re-use of construction<br />
materials will be improved eventually, but it<br />
takes time to remove the obstacles –<br />
economic, practical, <strong>and</strong> legislative<br />
The challenges have produced attempts to<br />
solve the problems in reducing C&DW, for<br />
example in Nordic countries…<br />

”Assesment of initiatives to prevent waste from building <strong>and</strong> construction sectors”<br />
http://www.norden.org/en/publications/publikationer/2011-533<br />
“The present report has identified <strong>and</strong> evaluated waste prevention initiatives for the<br />
building <strong>and</strong> construction sector. In total 32 initiatives have been identified <strong>and</strong> grouped<br />
into seven categories. The categories are:<br />
Reuse of building materials<br />
Information <strong>and</strong> awareness campaign<br />
<strong>Waste</strong> prevention guidelines<br />
Voluntary agreements<br />
Identification of hazardous substances<br />
Tools for registration of non-hazardous building materials<br />
Certification schemes<br />
Seven case studies, one from each category, have been described <strong>and</strong> assessed<br />
individually. The study has shown that waste prevention measures only to a<br />
limited extent appear to be an integrated part of the building <strong>and</strong> construction<br />
sector.<br />
Most of the activities named waste prevention by the stakeholders are in fact<br />
established in order to reduce l<strong>and</strong>filling.<br />
The main focuses of the activities identified by this study are related to<br />
recycling, whereas actual waste prevention is a minor part of the initiatives<br />
only.” (s. 9)<br />

C&DW as raw material for <strong>SRF</strong><br />
Previous choices in design <strong>and</strong> construction<br />
define the possibilities of recycling<br />
Recycling only the residue material that is not<br />
re-used in construction<br />
Amounts require industrial scale processing<br />
Incoming material source-segregated or<br />
presorted in various ways<br />
Recovery <strong>and</strong> recycling within technical <strong>and</strong><br />
economic limits<br />
Feedstock to MRFs<br />
Mostly from renovation<br />
Mostly mixed C&DW<br />
Varies according to source-segregation<br />
practices <strong>and</strong> weather conditions<br />
Portion of fines or ”unders” remarkable<br />
Controlling dust emissions in <strong>production</strong><br />
Controlling concentrations in <strong>SRF</strong><br />
Structural use in l<strong>and</strong>fills reduced in 2016<br />
at the latest<br />

Drivers <strong>and</strong> hurdles in producing <strong>SRF</strong> from C&DW<br />
CEN/TC 343 & EN 15359 provide clarity<br />
St<strong>and</strong>ards <strong>and</strong> quality controls<br />
provide a framework<br />
Actual <strong>production</strong> modified further<br />
by end-user specifications<br />
Co-operation of producers <strong>and</strong> users by<br />
integrating facilities<br />
Amount of C&DW high in near future<br />
<strong>SRF</strong> still classified ’waste’<br />
