The project, coordinated by the RIVM, started in 1985 and finished in 1990. The objectives of the project were: - to obtain systematic information of the leaching behaviour of a number of (waste)materials and products made from these materials. - to create a data-base filled with the above mentioned information. - to deliver a contribution to the environmental normalization for the use of (waste)materials and products, made from these materials. This report describes the controling aspects concerning the cooperation between the four institutes. The possibility of exchange of knowledge has played a vital role in the success of this project.74 pnl17projectorganisatieinformatiestructuurprojectomschrijving; projectplanningprojectkostenmammoetprojectReport2012-12-12
