There are several hundreds of different gases in cigarette smoke which are harmful to health. However, without pretending to eliminate all harmful effect, activated carbon placed in cellulose acetate filters of some cigarettes creates an effective barrier, making it possible to trap some of the elements in the smoke.

Manufacturing cigarettes with filters
The use of activated carbon in adapted granular form, acting through adsorption, makes it possible to retain some of the harmful components of smoke.
As one of the leading manufacturers of coconut-based activated carbon specially designed for this purpose, PICA has, since 1960, established throughout the sector a reputation for quality, reactivity and adaptability with regard to the increasing demands placed on the tobacco industry.
Before being incorporated in filters and becoming the main ingredient, carbons are rigorously tested for their chemical properties and the taste of the smoke.
PICA's significant position in this market is due notably to its ability to master the key parameters of activated carbons at the time of their activation: purity, humidity, low dust content, low magnetic scale and particle size distribution. These parameters are essential for the tobacco industry.
La place importante de PICA sur ce marché tient notamment à sa capacité à maîtriser les paramètres clefs des charbons actifs lors de leur activation : pureté, humidité, faible part de poussières et particules non carbonées, ainsi que la distribution en taille de grain. Autant de paramètres essentiels pour les industriels du tabac, mais aussi pour les consommateurs.
