Olf-Actions International LEGAL | TECHNICAL | SCIENTIFIC | ENGINEERING | ODOR EXPERTS The heart of our firm is odors and their precise measurement. Contratto, P.E., M.E. | 2026

The creation of Olf-Actions International is the culmination of an entire career dedicated to every dimension of odors, olfaction, quantification, and odor treatment | through all scientific, technical, and legal means available. To illustrate the scope and depth of this commitment, here are the key numbers:

๐Ÿ”ด 5,000+ olfactometric assessments | diagnostic mandates including all forms of sampling,

chemical and olfactometric analyses, and precise measurements such as GC-MS-O.

๐Ÿ”ด 1,200+ atmospheric dispersion studies | mainly modeling of odor and contaminant impacts, plus R&D mandates across many industrial sectors.

๐Ÿ”ด 130+ legal mandates | injunctions, lawsuits, complaint handling, disputes, class actions (19 won at 100% success rate), and expert witness engagements.

๐Ÿ”ด 60+ industrial process installations | absorption, biofiltration, activated carbon, air stripping, purification, gas washing, neutralization, oxidation, photocatalysis, plasma, and more.

๐Ÿ”ด 33+ years of practical experience | a full career accumulating knowledge and recognition before being acknowledged as both a technical-scientific and a regulatory-legal expert.

๐Ÿ”ด 22 countries served | with numerous worldwide assignments meeting industrials, complainants, attorneys, judges, legislators, standard setters, and air quality laboratory directors.

๐Ÿ”ด 20 engineering fields mastered | mineral, organic, analytical, and atmospheric chemistry; kinetics; atmospheric dispersion; law; electronics; computer science; environmental legislation; advanced mathematics; fluid mechanics (Eulerian and Lagrangian); meteorology; climate forecasting; industrial processes; programming; statistics; thermodynamics; and toxicology.

๐Ÿ”ด 15 odor regulations authored | across 15 jurisdictions worldwide, at municipal, state, and national levels.

๐Ÿ”ด 14 international laboratory partnerships and installations | BMW (Germany), CIRSEE/Suez (France), CERTECH (Belgium), ร‰cole des Mines d'Alรจs / Olentica (France), Givaudan (Switzerland), IFF (France), IRSN (France), Ministry of Agriculture (Israel), MKE (Korea), Odotech (Chile), Strenghts (Spain), University of Santa Catarina UFSC (Brazil), and the City of Montreal (Canada).

๐Ÿ”ด 1 expertise firm | Olf-Actions International | a lifetime dedicated to the sense of smell and flavors since the age of four, contributing to the development of patents for 2 atmospheric dispersion software, 2 dynamic dilution olfactometers, 3 generations of electronic noses, and 5 professional odor sampling and quantification instruments now used by consultants around the world. These numbers explain why the term "multidisciplinary" remains the only one capable of describing the skills required to practice our profession as odor experts. Olf-Actions International offers the widest range of scientific, technical, and legal services related to odors on all five continents.

Across the United States ๐Ÿ‡บ๐Ÿ‡ธ, too many municipalities have learned to hide behind the size of a contract.

A multimillion dollar engagement with a household name firm becomes the answer to every council question. We hired the biggest, we are handling it. Meanwhile odor season returns, the complaints pile up, and years later the community sits exactly where it started.

๐—Ÿ๐—ฒ๐˜ ๐—บ๐—ฒ ๐—ฏ๐—ฒ ๐—ฐ๐—น๐—ฒ๐—ฎ๐—ฟ. A contract is not a solution. A model that sits on a shelf is not a result.

I say this with direct knowledge of the field. I have personally trained engineers who now work inside some of the largest consultancies in this space. Scale is not expertise. Volume of billing is not resolution.

Odor is a measurable, solvable engineering and regulatory problem. It calls for independent specialists who own the outcome, not generalists who own the invoice. This is where real accountability begins.

Communities under enforcement deserve a defensible result. Residents deserve to open their windows again. ๐Ÿ‡บ๐Ÿ‡ธ

So here is the honest question for every council and utility board with a stalled odor file. After all that spending, has anyone actually resolved the odor? If the answer is no, it is time for independent and genuine .

Resolution, not invoices. That is the standard.

Working in a niche. A field so specialized, so singular, that you share it with barely a dozen peers across the entire world. That is some of the common ground I share with the talented Sarah Bouasse, journalist and author of "Par le bout du nez" (Calmann-Lรฉvy).

I have rarely felt such a sense of shared experience as I did reading this book. Its olfactory inventories are so many intimate journeys, so many common memories, often generational ones, each carrying you back to the scents of your own childhood and life.

It is a renewed pleasure with every page. And if the sense of smell intrigues you at all, this is, without hesitation, my finest summer reading recommendation of the year.

๐Ÿ”ป FOR FORTY YEARS, AMERICAN OPERATORS HAVE LIVED WITH ODOR SCIENCE THAT BELONGS TO ANOTHER ERA. THAT ERA IS CLOSING.

๐Ÿ”ป While inspectors walk public sidewalks holding plastic-and-rubber field devices, our team deploys sealed dynamic sampling under continuous meteorological monitoring. While outdated dilution-to-threshold readings are reported as defensible measurement, our laboratories deliver certified EN13725:2022 olfactometry with documented panel calibration and GC-MS chemical confirmation. While entire industries are regulated, fined, and litigated on the basis of figures that do not meet the basic requirements of modern olfactometric and atmospheric science, our Lagrangian and AERMOD dispersion modeling, validated over more than five years of hourly meteorological data, withstands regulatory review, peer scrutiny, and judicial cross-examination.

๐Ÿ”ป Cannabis cultivation | Rendering | Pulp & paper | Wastewater treatment | Landfilling | Composting | Pet food. The American operator deserves measurement that is precise, reproducible, and defensible. Today, that operator is rarely getting it.

๐Ÿ”ป Olf-Actions International | the only firm in North America combining certified olfactometry, atmospheric dispersion modeling, engineering mitigation design, and senior legal expert witness testimony in a single integrated mandate. 130+ legal cases. 19 global class actions. All successfully defended.
