Pioneering new solutions to help reduce environmental contaminants in our water and soil. 

Industrial activities like chlor-alkali plants, chemical manufacturing, munition manufacturing and metal mining can release mercury, contaminating soil and water, and impacting the food chain. This poses a significant health risk to humans and other species, particularly through fish consumption.

Albemarle's remediation technology is a powerful solution that captures and sequesters different forms of mercury, including the element itself, ionic compounds and even methylmercury, which can be particularly harmful. 


Albemarle's MercLok™ technology* can reduce leachable mercury and methylmercury concentration, by up to 99%, strongly reducing accumulation of mercury in biota. 


  • Albemarle’s advanced remediation solutions have been measured by rigorous industry-standard testing, such as the U.S. Environmental Protection Agency (EPA) methods.** 
  • Our solutions have been proven highly effective in cleaning up and stabilizing contaminated sites. 
  • We're committed to developing innovative practices that benefit both humanity and the environment.

MercLok™ Offers a Delicate Ecosystem a Second Chance

Several years ago, the owners of a ranch containing an old, abandoned mercury mine in the hills of California were faced with the prospect of containing the site’s mercury-contaminated mine waste. The conventional options included frequent surface grading, concrete capping, and amendments designed for other heavy metals, but these measures have generally failed to contain mercury beyond a few years. Building a landfill on the site or trucking away contaminated soil to a landfill were other mitigation options, but these were very expensive, and would further damage the ecosystem. 


In 2020, Albemarle secured access to the site for a study of its promising new solution for mercury stabilization and worked with the landowners to resolve the mercury contamination. 

“MercLok™ could totally change how mercury is remediated and really change the world.”
