The sales volume in 2007 is slightly less than in 2006: 7.948 MT vs. 8.122 MT. Given the
quite big uncertainty, this is not taken as relevant; all the more that in the whole, secondary
products on the market have steadily been rising in the last years. Furthermore, one should
consider that there are stockpiles of certain materials, especially of recycled mixed aggregates
and Recycled asphalt aggregates.
A similar listing has been shown in [VSS 2002]. There was given a total of 5.4 MT of
recycling material by the ARV, therefore being much higher than the 3 MT in 2006 and 2007.
Investigations resulted in the supposition that these data probably have been estimated
including materials not following the quality guidelines.
According to Mr Suter, executive of ARV, data of ARV and FSKB account for about 70% to
80% of all recycled materials in the construction sector. The total amount of discharge of
recycled materials can be estimated to be 13 MT per year. This is higher than the mentioned 9
MT in Figure 4; one has always to consider that all data are estimations. Given the total need
of about 60 MT of construction materials in the Swiss market, recycling materials can cover
about 20% of the need, even if the recycling rate is at 80% today. It has further to be taken
into account that, for example, 125% of input material may be required to reach 100% of
usable material [Gellenkemper, et al. 2004]. This means that even if a rate of 100% recycling
would be reached, only about ¼ of the total construction materials market could be provided
with secondary materials. For example, as to [Lichtensteiger 1997], the percentage of
recycled material in the whole stock of Swiss buildings is lower than 1%. Please note that
these calculations can differ much from material to material. The input of secondary gravel
for example is estimated to be at about 10% of total gravel demand [FSKB 2008a].
