Inside The Factory
What sixty years of production actually looks like.
Photographed on-site at Bhagowal — the rotary kiln, the raw activated carbon, and the testing bench, exactly as they run today.
Pinex Chemicals has manufactured activated charcoal carbon since 1963, refined through British-technology processing and tested batch by batch for the pharmaceutical and bulk drug industries.
Began working in activated charcoal manufacturing in 1963, building Pinex Chemicals into a specialist producer trusted for consistency across every grade.
What started as one man's expertise in activated charcoal has grown into a manufacturing operation built on the same principle he started with: every grade tested before it leaves the factory.
Pinex Chemicals uses British-technology processing to produce charcoal activated carbon suited to demanding, high-purity applications — most notably for the pharmaceutical and bulk drug industries, where consistency isn't optional.
The factory in Hoshiarpur, Punjab remains where it began, running an advanced testing laboratory alongside production so quality is verified in-house, on every batch, before dispatch.

Manufactured for high-adsorption use cases where purity of the final product depends entirely on the quality of the carbon used to refine it. Available in unwashed and acid-washed grades.

Purification steps within pharmaceutical and bulk drug production, where adsorption quality directly affects final product safety.
Removing colour bodies and impurities from process liquids that require a clean, consistent finish.
Every batch produced against the same tested standard, so formulations relying on this carbon don't have to be re-validated each time.
An in-house lab dedicated to verifying every grade of activated carbon produced.
Manufacturing built on established activation technology, refined over decades of operation.
Decades of hands-on expertise, carried from the founder through to today's operations.
