EcoBright™ Series

EcoBright Series

  • Cost savings
  • Ecofriendly
  • Reduced chemical consumption
  • Fiber strength
  • Minimized effluents

EcoBright is an optimal source of alkali in pulp bleaching, helping to save costs, reduce chemical consumption, increase fiber strength and minimize effluents.

Pulp bleaching is a necessary process for the production of both graphic paper and some packaging board grades. 

EcoBright is a stabilized aqueous suspension of magnesium hydroxide that is not only environmentally friendly, but delivers cost savings by ensuring optimized use of magnesium sulfate, caustic soda, silicate and/or hydrogen peroxide in the recipes.

EcoBright HP is specially recommended for the use in high performance hydrogen peroxide bleaching. It serves as a multi-function ingredient by providing alkalinity and a buffering effect as well cellulose fiber protection by the magnesia ions. 

Using the EcoBright product series in pulp bleaching can achieve many benefits including:

  • Higher brightness values
  • Less COD/BOD burden
  • Less dissolving of organic material hence higher yield and cleaner water circuits
  • Significantly reduced downtime for process equipment cleaning due to reduction in calcium-based deposits, leading to  improved productivity
  • EcoBright slurries are not classified as hazardous following the harmonised system for CLP

No matter the mechanical or chemical pulp application, let our innovative team help determine or create a solution specifically for you.
