Abstract The hazardousness of waste could be soon assessed in Europe by the hazard properties of its constituents. A quasi exhaustive knowledge of its constituents will therefore be necessary. A conceptual scheme of waste composition is proposed for analysis purpose, including unresolved pools of probably higher molecular weight organic substances supposed to be less bioactive and less hazardous ('non extractible organic compounds', 'unidentified volatile compounds' and 'unidentified semi-volatile compounds'). Screening ICP methods are used for major elements, and screening GC MS methods are used for volatile and semi-volatile organics. 32 laboratory samples of different industrial wastes have been tested following (with differences) this protocol by two (routine) service laboratories, with about 7 000 parameter results. A satisfactory analytical balance of 90 % is reached for 20 samples (63 % of the samples) during this first run, with identified reasons for most of the unsatisfying results. A first exploratory classification of the wastes for their hazardousness according to the Seveso legislation was performed based on data from the (chemical) CLP regulation. Using the CLP data, out of 32 samples, 27 (84 % of the samples) were classified identically by the two laboratories (23 not hazardous and 4 hazardous). Using additional EC50 data, out of 32 samples, 27 (84 % of the samples) were classified identically by the two laboratories (13 not hazardous and 14 hazardous).
