Westrand

Founded in 1992, Westrand develops patented active ingredients that neutralize odors rather than mask them. The company's products combine natural and synthetic essential oils with aldehydes to chemically bind with malodorous compounds like sulfates, mercaptans, ammonia, and amines. Applications span wastewater treatment plants, landfills, composting facilities, petrochemical plants, and industrial sites. Westrand holds multiple French and European patents and has passed biodegradability, ecotoxicity, and inhalation tests. The company also offers site-specific remediation services for former gas plants, chemical dumps, and refineries.
