Plant-Based Dust Suppressants — Arizona
Jenterra supplies and applies plant-based, non-chloride dust suppressants that control fugitive dust without corroding equipment or salting your soil. Derived from renewable sources, they're biodegradable and safe for plants and water — a responsible alternative to calcium and magnesium chloride for haul roads, lots, and construction sites.
How plant-based dust control works
Plant-derived binders — soybean-ester, lignin, and sugar or starch based formulations — coat and bind fine soil particles into heavier agglomerates that stay on the ground instead of lifting into the air. Applied as a dilute spray and worked into the surface, they build a flexible crust that tolerates traffic and re-forms under compaction.
Because the binder is organic rather than hygroscopic salt, performance does not depend on pulling moisture out of the air — an advantage during Arizona's dry pre-monsoon months when chloride products lose effectiveness.
Chloride vs. bio-based
Calcium and magnesium chloride are the default in a lot of Arizona sitework, and they work — but they are corrosive to equipment and rebar, and repeated application adds salt to soils and runoff. Over time that over-salinization damages roadside vegetation and can carry into washes and waterways.
Plant-based suppressants are marketed as non-corrosive, biodegradable, and safe for plants and aquatic life. Longevity and coverage rates vary by product, soil, and traffic load — treat vendor longevity figures as manufacturer claims and confirm the application rate for your soils.
- Non-corrosive to equipment, fasteners and reinforcement
- Biodegradable; breaks down without leaving a salt load
- No chloride contribution to stormwater or roadside soils
- Compatible with revegetation and landscape areas
Rule 310 compliance
Maricopa County Rule 310 requires dust control on construction sites, including stabilized haul routes, disturbed surfaces, storage piles and trackout control at every access point. A stabilized surface treated with an approved suppressant, documented and re-treated on schedule, is a straightforward way to hold compliance between inspections.
We coordinate application with your dust control permit and site schedule, and can pair suppressant application with trackout control and stabilized construction entrances.
Application & re-treatment
Application is a water-truck or distributor spray at a rate set by soil type, traffic volume and surface condition, usually after grading and light watering so the binder penetrates rather than sheets off. Heavily trafficked haul roads take a higher initial rate and a maintenance re-treat; low-traffic lots and stockpiles hold far longer.
We supply product by the tote or tanker for crews that apply their own, or we apply it ourselves — including scheduled re-treatment through the dry season and after monsoon washouts.
Where we work
We supply and apply across metro Phoenix — Phoenix, Scottsdale, Mesa, Chandler, Gilbert, Tempe, Queen Creek, Peoria and Surprise — plus the high-desert corridor of Flagstaff, Prescott and Payson, and south to Tucson.
Frequently asked questions
- Are plant-based dust suppressants better than chloride?
- Yes for most sites — plant-based suppressants are non-corrosive and biodegradable and won't salt your soil, unlike calcium or magnesium chloride, while still binding dust effectively. Chlorides can still make sense on some unpaved road maintenance programs, and we'll say so if that's your case.
- Is it Rule 310 compliant?
- Plant-based suppressants can be used as a surface stabilizer under Maricopa County Rule 310 when applied and maintained to keep the surface stabilized. Compliance depends on your dust control permit, application records and re-treatment schedule — we apply and document both.
- How long does one application last?
- It depends on soil, traffic and weather. Low-traffic lots and stockpiles commonly hold a full season, while active haul roads need periodic maintenance re-treats. Manufacturer longevity claims vary widely, so we set a re-treatment schedule based on your actual traffic.
- Is it safe around plants, animals and water?
- Plant-based products are formulated from renewable sources and marketed as non-toxic and biodegradable, which is why they're used near landscape areas and drainage. We'll provide the SDS and product data for the specific formulation used on your site.
