Landfill & Solid Waste Odor Control Solutions

Effective Odor Control for Landfills and Solid Waste Management

Landfills are a major source of unpleasant odors produced by the decomposition of solid waste such as organic matter, industrial waste, and hazardous materials. These odors can contain harmful substances like mercaptans, VOCs, and ammonia, which can result in non-compliance fines from local governments and pose a threat to human health.

In order to avoid fines and stay complaint it is important for landfill operators to combat these odors using effective, and proven odor control solutions that are both safe and cost-efficient.

Air Treatment Solutions

To prevent landfill odors from escaping into nearby communities, Benzaco provides fixed or portable delivery systems. In a fixed system, high-pressure hoses and nozzles are evenly placed around the perimeter of the landfill, leachate pond, or gas treatment system.

The odor-counteractant formula is then dispersed using high-pressurization systems such as vapor-phase and atomization that create a continuous fog that neutralizes obnoxious odors and prevents them from escaping into nearby communities.

Odor-Armor® Distribution Systems for Landfills

Systems for Mobile Atomized Treatment

In a landfill, it can be difficult to predict where an odor might arise. To combat this, Benzaco provides mobile systems that can disperse Odor-Armor® counteractants swiftly throughout the property through portable sprayer systems or water-trucks with mounted dispersal systems.

Odor-Armor® can be applied topically using these systems for spot treatment of problem locations such as exposed landfill and road areas, trucks carrying odorous cargo, or simply spraying down equipment such as scales to eliminate any leftover smells. Dilution rates of as much as 10,000:1 is possible for very economical application rates.

One-size-fits-all solutions simply don’t work in this industry due to the many factors that affect the type of odors that are produced, the age and condition of the landfill, and their proximity to urban areas.
