Sustainable Chemistry

� Sustainable chemistry builds upon the principles of green chemistry by integrating economic viability and socialbenefits across the lifecycle, for a given application.

� More sustainable products require more efficient use of materials and resources , and must also be profitableand useful to society .

8

Sustainable biocides

� The proper use of biocides is good forsustainable development …

� keeps a hygienic environment� increases durability of products, process fluids� allows use of water-based or natural products� reduces CO2 emission, enhances energy-efficiency

� … but biocides also have an impact on the environment that must be mitigated

9

A Relevant DefinitionA sustainable biocide should:� do its job effectively :

� Control and Prevent nuisance and growth of harmful microorganisms

� And Goes Away :� Degradable� Non-Persistent� Non-Accumulative� Collected and recycled / reused� Destroyed

� does No Harm to :� Workers, products or processes� Downstream users, consumers� The environment� Society

Additional pressure expected on traditional algaeci des

� Terbutryne has been identified by the EU Commission and could join Diuron and Isoproturon on the Priority Substances List under the Water Framework Directive (2000/60/EC).

� The impact of inclusion on the Priority List is 3-fold:

� The EQS (Environmental quality standard) proposed are very low, close to the PNEC.

� Increase monitoring in the European water bodies even at very low level, so priority substances will likely be more detected

� This will negatively impact their evaluation under the BPR for any dispersive uses like PT7 (exterior paints), PT10 and PT21. This together with the fact they are all persistent (so meet 2/3 PBT criteria) will probably make them candidates for substitution (if not directly banned).
