Waste reduction final report -4 - Test Input

a recommendation and its application is voluntary. However, there are a number of standards
which are mandatory because they are referred to by legislators or authorities laws or decrees
[SNV 2009].
For economic people it is essential to gain safeness through reliable standards so that they
consider the application of recycled materials in their constructions. The appendix shows a
compilation of the current standards concerning sustainable construction and construction
waste.
The most important standards in view of construction waste reduction are:
- SIA 112/1, SIA 162/4, SIA 430
- SN 640 141 to 144, SN 670 062
Notions as to the guidelines and standards:
According to the Excavation Guideline, the Guideline for the Utilization of Mineral Waste
Material and SIA 430, construction and demolition waste is grouped into four different types
as follows:
Excavated material (“Aushubmaterial”) is all material coming from the activities of
excavation, quarrying and spoil (Aushub, Abbruch, Abraum). It stems from soil horizon C
(parent rock material). Excavated material is denoted “not contaminated” when no
anthropogenic change of the natural chemical or substantial composition can be identified.
The material can therefore be reused or landfilled without constraints. If excavated earth is
denoted as “tolerable” or “contaminated”, it has to be treated according to the TVA [FOEN
1999].
This term is used as a synonyme for mineral construction waste and is therefore set in the
guideline for the utilization of mineral waste [FOEN 2006]. This kind of waste has to contain
at least 90 % in weight of materials similar to rock. Construction and demolition debris is
further differentiated into:
- Road construction waste (“Strassenaufbruch”): This includes material generated by
breaking open or milling of uncombined layers of foundations or base and binder
courses. This waste is constituted out of road planings (top layer as waste) and road base
waste (lower layer waste).
- Asphalt waste (“Ausbauasphalt”): Asphalt waste is obtained through cold milling or
through breaking open of bituminous layers.
- Concrete waste (“Betonabbruch”): Breaking down or milling of reinforced or nonreinforced
concrete constructions or coatings results in concrete waste.
- Mixed C&D waste (“Mischabbruch”): As the name implies, this is a mixture of mineral
construction waste stemming from massive building elements such as concrete or
bricking.
Bulky construction waste (“Bausperrgut”) is other construction waste which can’t be
allocated to the above groups, e.g. wood, metals or plastics. These should be separated into
reusable and non-reusable waste [SIA430 1993].
Special waste (“Sonderabfälle”) has properties which can become dangerous when handled
without care. As a result, it has to undergo special treatment and is subject to the VeVa
mentioned above [SIA430 1993].
