A Global Generic Drug Manufacturer
Increases Productivity and Profitability Implementing a Low Residue Programme


When a global generic drug manufacturer that was generating an annual revenue of $20 billion was utilizing a disinfection process that was hindering production, they sought a new solution that would reduce the amount of residue being left behind.

The site had previously relied on an in-house manufactured chlorine solution for disinfection programmes which lacked the required efficacy, and their main objective was to increase the effectiveness of this solution. A Quat Concentrate from a chemical supplier was also used on site which caused residue issues.

The leadership team reached out to Ecolab to explore and implement a cost reduction and process improvement project, focusing on optimizing the Standard Operating Procedures (SOPs) and disinfection programmes in use across the site. This new process would go on to be analyzed and duplicated across other sites within the organisation.


After a completed site survey with Ecolab’s technical team to review existing processes in place, the organisation came up with the project objective of testing the Klercide Sporicidal Low Residue Peroxide and Klercide Low Residue Quat to evaluate the benefits of these low residue solutions. The goal was to first test these products on the new production line, with a plan to then implement the process across their parenteral lines if successful and proven to show excellent efficacy.

The Klercide Sporicidal Low Residue Peroxide was to be used in rotation with the Klercide Low Residue Quat on equipment and the production line along with daily use in some other areas. For large surfaces, the Klercide Low Residue Quat was used while the Klercide 70|30 IPA was used on small surfaces in all grades of cleanroom (A-D).


On a daily basis, no residue removal step was needed with the Klercide Low Residue Quat for equipment, lines and large surfaces.

Savings were also made using this new solution compared to the previously used Quat Concentrate which was an old formulation that was leaving residues.

Implementing this newly validated strategy and combining the right product with best practice, the pharmaceutical company was able to make significant savings and increase its productivity.
