Eco-Vista, LLC continually invests in the facility to install systems designed to reduce the potential for offsite impacts from the operation. Eco-Vista, LLC engages with a variety of internal experts and third party consultants and contractors to assist in the design and installation of engineered solutions to control off site odors and reduce the conditions that produce them.
We also engage with third party engineers and scientists to monitor the facility and are regulated and monitored by the Arkansas Department of Energy and the Environment, Division of Environmental Quality (ADEE, DEQ).
Landfill Gas Collection System
Landfill gas is formed when waste materials decompose. The gas is approximately 40-60% methane. Gas extraction wells are constructed in the landfill to capture the methane and pipe it to the gas-to-energy plant for processing. The electricity generated from the gas-to-energy (GTE) plant is directly fed into the municipal power grid for use by electrical consumers. This facility can produce approximately 4 megawatts of electricity, which is equivalent to the amount of energy consumed by approximately 4,000 homes annually.
Cover Systems
Cover soils help to control odors by sealing the outside of the landfill so that any gases and odors can be directed to the odor control system. The site is continually placing cover soils on areas that are not actively receiving waste. The slopes that are at a final grade also are seeded to reduce the potential for erosion.
Eco-Vista uses Atmos Daily Cover System (previously RusMar) for class 1 daily foam application. The site is currently one of seven WM locations utilizing foam as an alternate daily cover. In September 2021, DEQ approved long-term use of foam as an alternate daily cover. The product repels vectors, preserves airspace, controls odors, and improves employee safety. It consists of biodegradable protein-based materials. Through innovative environmental practices, Eco-Vista strives to protect the world around us.

Misting System
In December 2021, we upgraded our misting system to a Benzaco Scientific Odor-Armor® System. For more than 25 years, Odor-Armor® products have been used in a wide range of commercial and industrial applications to combat odors. Formulations have been developed with industry specific objectives and then matched to delivery systems that can maximize cost efficiency, reliability and performance. These systems use a water based non-toxic neutralizer to help control any odors that may be generated from the active working area of the landfill.
Odor-Armor® is a proprietary blend of natural plant extracts held together in a stable, homogeneous emulsion with an EPA approved food-grade surfactant. The surfactant then allows the natural plant extracts to be mixed and diluted with water, at a target rate of 500:1 to 1000:1 to manage potential smells.
