1. Results of the Survey on Mining and Quarrying Waste Statistics
Jürgen Gonser ARGUS, Berlin
Workshop on mining waste, 11./12. October 2011

2. Survey on Extractive Waste Statistics
Intention of the survey:
to gain a better understanding of differences between countries
to identify the need for clarification and guidance
to provide a basis for proposals to harmonise reporting on extractive wastes
Workshop on mining waste, 11./12. October 2011

3. Survey on Extractive Waste Statistics
Information collected from countries:
Problems encountered and need for clarification
Main waste generating activities carried out by extractive industries in the country
Main waste types generated by extractive industries
coverage of national data with regard to:
main waste categories
waste treatment facilities

7. Coverage of waste statistics
Workshop on mining waste, 11./12. October 2011

8. Coverage of waste statistics
Main reasons for complete or partial exclusion from reporting:
Not considered as waste:
mainly for topsoil
also for clean inert wastes (IE, PT, ..)
Waste is managed on the site where it is generated, mostly for recovery purposes (backfilling, etc.)

9. Coverage of waste statistics
Waste generated in NACE B related to population (2008)

10. Problems encountered (1)
Uncertainty about what should be reported:
distinction between waste and non-waste
what is the scope to the WStatR
Uncertainty about definition and classification of treatment operations
Lack of guidance on these issues
Limited comparability even on national level
Management of extractive waste may be regulated under mining law and not under waste legislation.

11. Problems encountered (2)
Lack of expertise in environmental administration or statistical institutes
Problems around estimating tonnages where waste is no weighed (e.g. stockpiled material)
Considerable variation of waste amounts from one year to another
Uncertainty about how to report extractive waste generated under other NACE sections
Workshop on mining waste, 11./12. October 2011

12. Conclusions
In order to achieve harmonised reported the following is necessary:
Clarification of what should be reported:
which materials / waste types?
which treatment operations?
Once these question are clarified guidance should be provided in order to safeguard a consistent implementation
