5. Norwegian authorities - objectives concerning C&D-waste: reduce the consumption of primary raw materials, control handling of hazardous waste, increase lifespan of existing landfills by reducing landfilled volume of waste

6. Building industry: National action plan for C&D waste: By 2005, no more than 30 % of the annually generated waste should be landfilled.

7. Pollution control authorities (SFT), criteria for recycled materials: Material must have a function The material must satisfy specifications There must be a commercial interest The material must be clean

8. Norwegian Public Roads Administration: Recycling R&D program * arrange for more frequent and environmentally safe use of recycled materials in road constructions: 2002 � 2005

MEN: utlekkingstall blir hentet fra de mest relevante metoder. Dette betyr en tidshorisont p� maks 64 dager dersom standard metode skal benyttes. Jeg jobber akkurat n� med � finne ut av hvilke metoder som b�r brukes for cement, slik at dataene kan g� inn i neste trinn. Vi har kommet s� langt at spesifikke metoder b�r nevnes (ikke forklares) Konklusjon: P� lysbildet b�r vi konkretisere med noe av det ovennevnte� will determine the relevant method for determination of leaching charactyeristics Vi pr�ver � spesifikisere hvert av trinnene s� langt vi kan, eks: description of scenario.

23. Methodology for risk assessment Modelling in order to estimate long term release NB! 64 dager er en NEN test. Grunnen til at jeg nevner 64 er at det er en av de lengste standard metodene jeg har sett jmf. time frame i trinn 4 � nevne direkte modeller er nok vanskelig (husk at vi p� en m�te b�r gj�re/pr�ve � gj�re det vi presenterer i et slikt forum. Alle vet at PHREEQE kan benyttes men det er meget tidkrevende), men jobber med � finne enkle modell approach i litteraturen. Har allerede noe i Kosson et al. En l�sning er � si at p� cement based mat s� skal PHREEQE eller basert p� denne modellen benyttes. Modelling in order to estimate long term release NB! 64 dager er en NEN test.
