A plasterboard includes a first layer of plaster and a second layer of plaster, wherein the first layer includes activated carbon; the second layer includes a scavenging agent, wherein a content of scavenging agent in the first layer, expressed as percentage by weight of dry matter, is less than a content of scavenging agent in the second layer, and wherein the second layer is free of activated carbon.

Plasterboard

A process for the manufacture of a plasterboard including activated carbon, includes: preparing a main mixed batch including a foaming agent and devoid of activated carbon; preparing a secondary mixed batch including powdered activated carbon; providing a first facing sheet; pouring the secondary mixed batch over the first facing sheet, the secondary mixed batch forming a first plaster layer; pouring the main mixed batch over the first plaster layer, the main mixed batch forming a second plaster layer; providing a second facing sheet on the first and second plaster layers; and forming the plasterboard; wherein the secondary mixed batch has a greater density than the main mixed batch.
