Cigarette butts: A small but hazardous waste, according to European regulation.

The emergence of companies collecting cigarette butts (CB) leads to a new waste stream, exclusively made of butts, whereas they were previously mixed with household and municipal waste. In order to conclude on the classification of this new stream, according to the Waste Framework Directive, three cigarette butts samples were analyzed and submitted to ecotoxicological tests. Hazard properties HP 4 (irritant - skin irritation and eye damage), HP 5 (specific target organ toxicity/aspiration toxicity), HP 6 (acute toxicity), HP 7 (carcinogenic), HP 8 (corrosive), HP 10 (toxic for reproduction), HP 11 (mutagenic) and HP 13 (sensitising) have been assessed by calculation, thanks to the analytical results.

Assessment of four calculation methods proposed by the EC for waste hazardous property HP 14 'Ecotoxic'.

Legislation published in December 2014 revised both the List of Waste (LoW) and amended Appendix III of the revised Waste Framework Directive 2008/98/EC; the latter redefined hazardous properties HP 1 to HP 13 and HP 15 but left the assessment of HP 14 unchanged to allow time for the Directorate General of the Environment of the European Commission to complete a study that is examining the impacts of four different calculation methods for the assessment of HP 14. This paper is a contribution to the assessment of the four calculation methods. It also includes the results of a fifth calculation method; referred to as "Method 2 with extended M-factors".

Hazard property classification of waste according to the recent propositions of the EC using different methods.

Hazard classification of waste is a necessity, but the hazard properties (named "H" and soon "HP") are still not all defined in a practical and operational manner at EU level. Following discussion of subsequent draft proposals from the Commission there is still no final decision. Methods to implement the proposals have recently been proposed: tests methods for physical risks, test batteries for aquatic and terrestrial ecotoxicity, an analytical package for exhaustive determination of organic substances and mineral elements, surrogate methods for the speciation of mineral elements in mineral substances in waste, and calculation methods for human toxicity and ecotoxicity with M factors.
