WESTRAND INTERNATIONAL

1. WESTRAND presentation and history:

Westrand invented in 1993 the industrial odour removal profession based on neutralizing products.
Until then, only masking or over-smelling products existed.
Westrand produces and markets a very wide range of reagents (patented).
They are derived from a combination of natural and synthetic essential oils containing a mixture of aldehydes and ketones.

Westrand also design and install the engineering systems to diffuse these reagents.

We have 4 main sectors of activity:

• Garbage sector: household waste or chemical product incinerators, methane fermentations, non-hazardous waste storage facilities, sludge, and green waste composting, …
• Wastewater sector: wastewater treatment plants, gravity-fed sewers, lifting stations, lagoons, …
• Industry sector: Petrochemical, food industry, slaughtering, …
• Soil decontamination: old gas plants, chemical discharges, old refineries, old gas station, …

Westrand is recognized for its effectiveness and responsiveness.

A global company, Westrand is established in more than 25 countries with more than 1 500 references.

2. WESTRAND products:

1. Chemical reactions:

Our products are composed of natural and synthetic essential oils made up of mixtures of:

• Aldehydes
• Ketones

These mixtures neutralize by chemical reactions (see appendix) foul-smelling gases such as:

• Ammonia
• Amines
• Hydrogen sulphide
• Mercaptans
• Other

The use of our neutralizers ensures the decrease of 90 to 95% of the odour concentration.

2. Patents:

The main active principles used are covered by the following patents:

• French patent no. 2 599 257 of 29/05/1986
• Addition certificate no. 2 623 717 of 1/12/1987
• European patent no. 0401140 of 28/05/1990
• Patent no. 06/03903 of 2 May 2006
