Dust Solutions

-80% Water used. -90% Loss of product. 100% biodegradable. 100% safe.



Freko-Crust and EcoCrust is an additive, which uses biodegradable agents that forms a thin crust on stored stocks, sources of dust emissions such as coal, iron ore, sands, tailings, phosphates or sawdust.

  • The crust lasts anywhere from 1 to 90 days; application rates can be tailored to the performance of your location or delivery times.
  • The bark is unaffected by adverse weather conditions, such as high winds, heavy rain, hail or snow.
  • Eco-Crust is based on recycled fibers (EndOfLife) that allow for the addition of a colorant if visual distinctiveness is desired.

Removes dust on demand:

Dry bulk cargoes such as coal, sawdust, phosphates, cements, etc., cause a large amount of dust during storage and handling. External factors such as wind can cause strong impacts and are unpredictable.
Most companies look for solutions using water, mainly water spraying on bulk stockpiles.
Subsequently, this water must be cleaned with chemicals and also entails significant water expenditure and associated costs.


How it works:

  • Freko-Crust uses biodegradable agents that form a thin crust over the dust generated by stockpiled products such as coal, iron ore, sand, tailings, phosphate ore or wood chips.
  • The crust lasts a long time and is not affected by harsh weather conditions such as strong winds, heavy rain, hail or snow.
  • Based on specific needs, the duration of the bark can be adjusted to achieve cost savings.
  • Eco-Crust is based on recycled fibers instead of latex and offers similar functionality.
  • A colorant can be added for visual effect.

Advantages of Freko-Crust and Eco-Crust:

  • Over 90% dust reduction.
  • Water savings of more than 80% (treatment costs and expenses).
  • 90% reduction of product loss during storage and transportation.
  • 100% biodegradable.
  • 100% safe for people and the environment.

Freko-Crust and EcoCrust are aimed at industries such as:

  • Dry Bulk Loads and Logistics Warehouses.
  • Waste and Recycling.
  • Construction and Demolition.
  • Thermoelectric Power Plants.
  • Infrastructure and Civil Engineering.
  • Biomass.

Freko-Crust application demonstration video

In the following video from Wuvio Chemicals, you can see the spraying technique of Freko-Crust and Eco-Crust on stored coal, to avoid emitting dust particles into the atmosphere with the consequent loss of material and air pollution.
