A US factory worker surviving a malignant disease is reported to be driving his appeal in the court.

Last month, the worker suffering from "popcorn lung" disease was granted $US30.4 million ($A33.4 million) as per the jury’s ruling against a chemical supplier.

The supplier was held because a chemical was found in the butter-flavored microwave popcorn.

Ken McClain, the worker’s lawyer, outlined that the ruling by the court of awarding such a big amount to an individual is the first of its kind that has been witnessed in the country.

Gerardo Solis, 45, had been working in numerous popcorn and popcorn-flavoring plants in Chicago. During his working tenure, he was engulfed by a fatal respiratory disease called bronchiolitis obliterans. The disease resulted in over 75% damaging of the worker’s lungs, consequently landing his life in jeopardy.

His condition is so critical that he now requires a lung transplant, his lawyer claimed.

The lawsuit has highlighted that BASF did not publish warning over the health and safety hazards associated with diacetyl, in a view to caution Solis and his co-workers. Also, BASF has been accused for negligence over the chemical use, as it failed to advise its workers to make use of respirators and chemical suits while working on the plant.
