Anotec provides specialised odour control solutions across a wide array of industries, focusing on eliminating malodours rather than merely masking them. The company's core product, Anotec 0307, is a concentrated blend of nature-identical components, plant oils, emulsifiers, and non-ionic surfactants, designed to be diluted with water for various application methods such as atomising, fogging, misting, or drip-feeding. Anotec's technology works through a combination of physical adsorption, surfactant-induced absorption, counteraction, and condensation, breaking down odorous molecules into non-volatile forms that biodegrade naturally without causing secondary pollution. Anotec also offers PRO5L, a highly concentrated water-soluble liquid (also available in oil phase) formulated as an additive to reduce the volatility of odorous compounds in liquid mixtures.
Here's a summary of Anotec's odour control applications across various industries:
- Furniture Manufacturing Factories
- Odour Sources: Diverse volatile compounds including sulphides, alcohols, aldehydes, ketones, esters, freons, chlorinated hydrocarbons, and alkanes.
- Anotec's Approach: Applied as a treatment to factory exhaust.
- Effectiveness: Demonstrated a significant reduction in total odorous compounds, with concentrations dropping from 27,394.41 ppb to 296.53 ppb. Odour Dilution Units (ODU) were reduced from 55,000 to 2,050.
- Industrial Emissions (General)
- Odour Sources: A broad spectrum of volatile organic compounds (VOCs) and other industrial components.
- Anotec's Approach: Utilises its Odour Control Products (OCPs) which are designed to remove 90% or more of volatile organic compounds. These solutions are efficient for treating low concentrations of odorants (under 20 ppm) and importantly, do not create secondary pollution.

- Poultry Farms
- Odour Sources: A wide range of malodorous compounds, notably hydrogen sulfide, methyl mercaptan, ammonia, and acetone, typically from livestock and poultry sheds.
- Anotec's Approach: Uses Anotec 0307, with applications including wet scrubbing of exhaust air and spraying an oil phase product onto waste surfaces. Additives can also be introduced to deep pits.
- Effectiveness: Demonstrated high removal efficiencies: 95% for hydrogen sulfide, 99.86% for methyl mercaptan, and 98.12% for acetone. The ODU was drastically reduced from 22,569 to 894. Wet scrubbing can achieve 66-98% odour reduction, while surface spraying of oil phase products showed 70% reduction. Additives to deep pits provided approximately 32% year-round ammonia reduction.
- Sewage Treatment Plants / Installations
- Odour Sources: Common malodours include hydrogen sulfide, methyl mercaptan, dimethyl sulfide, and various other volatile organic and sulfur compounds resulting from anaerobic decomposition.
- Anotec's Approach: Anotec 0307 is specifically formulated for sewage installations and can be applied via atomising, fogging, misting, or drip-fed systems. Products like "EcoEnzyme Efficient odour control for septic systems" and "ANOTEC SFTY-100 ANOTEC BLUE" for portable toilets are also offered. The Cirrus Misting System is used for "scrubbing" malodours from emissions.
- Effectiveness: Achieved remarkable reductions: 99.86% for hydrogen sulfide and 99.96% for methyl mercaptan at a pumping station. ODU at a pumping station was reduced from 6,214 to 139, and at the Taree Sewage Treatment Plant, it dropped from 94,235 to 1,284. For general sewage stack emissions, many compounds saw over 99% removal, and hydrogen sulfide was reduced by 92.26%.
- Landfills (including composting windrows)
- Odour Sources: General malodours from putrescible waste.
- Anotec's Approach: Anotec 0307 is formulated for these applications, available in various container sizes for manual spraying or portable systems.
- Effectiveness: Designed to control and eliminate odours in these environments.
- Site Remediation (including ex-gasworks & service stations)
- Odour Sources: Odours from contaminated soil and sites.
- Anotec's Approach: Anotec 0307 is used. Additionally, ANOGUARD SOIL BINDER, a polymer-based soil binder, can be applied for odour control at remediation works and contaminated sites.
- Effectiveness: ANOGUARD SOIL BINDER works by forming a micro-film barrier on the surface to minimise or prevent erosion and control odours.
- Foundries (Ferrous & Non-ferrous)
- Odour Sources: Complex mixtures of compounds (e.g., amines, aldehydes, phenols, xylenols, triethylamine, formaldehyde, sulphur dioxide) emanating from mould preparation, casting, knocking out, and sand reclamation. These are typically nuisance odours rather than health hazards at ambient concentrations.
- Anotec's Approach: Anotec 0307 is recommended for controlling fugitive emissions. It combines chemical, counteraction, condensation, adsorption, and absorption technologies. Anotec employs chemical fingerprinting (GC/MS) to identify specific odorous components for tailored solutions. Application is often achieved by atomising the solution into exhaust stacks.
- Effectiveness: In a case study at Tyco Water Foundry, Anotec 0307 significantly reduced concentrations of major odour annoyance sources like ethanol, acetone, methyl acetate, toluene, m,p-xylenes, and benzene, achieving an overall reduction greater than 80% when atomised into the exhaust stack. Overall removal efficiency across various parameters was between 87-98%.
