Required regulations for the accreditation of a dynamic olfatometry laboratory in Colombia

Cardona   Achieving the designation of being the first accredited laboratory in Colombia to provide the service of dynamic delayed olfactometry, is the result of a process of innovation and incursion into the environmental diagnosis field, starting from the implementation of different regulations and legal requirements that are applicable at both national (Colombia) and international levels.

   For example, the presidential decree 1600 of 1994, that establishes the compulsory of the laboratories to accredit their technical competence before the Hydrology, Meteorology and Environmental Studies Institute (IDEAM), which is the entity designated to manage and coordinate the environmental information system; the resolution 0176 of 2003, that establishes the accreditation procedure of environmental laboratories in Colombia, and so on...

biological waste odours BREF   The 17th of August, the Decision of the European Commission establishing the best available techniques (BAT) conclusions for Waste Treatment (WT), have been published in the Official Journal of the European Union. This legislative text mentions fifty-three BATs for use in WT. Among those 53 BATs, the BAT number 34 includes 5 techniques: Adsorption, Biofiltration, fabric filter, thermal oxidation and wet scrubbing. This legislation sets a range of 200 to 1000 ouE/m3 as the maximum allowed odour concentration for these BATs for biological treatment of waste.

   The last meeting of the Technical Working Group that discussed the renovation of the former BAT Reference (BREF) Document on Waste Treatment (WT) took place in march 2017. After a few drafts and plenty of discussion, the final draft was published in October 2017. This final draft marked a new milestone in the odour management for twenty-eight (28) countries of Europe, as it was the first BREF that included an odour emission limit. This month the final conclusions of this BREF have been published and this odour limit is now law.
