[114] It was not until the introduction of wood pulp in 1843 that paper production was not dependent on recycled materials from ragpickers. [114]

They also note that most of the carbon captured in the U.S. now eventually gets injected into the ground to force out more oil, a process called enhanced oil recovery.
Before the industrialisation of paper production the most common fibre source was recycled fibres from used textiles, called rags. The rags were from hemp, linen and cotton. [7] A process for removing printing inks from recycled paper was invented by German jurist Justus Claproth in 1774. [7] Today this method is called deinking.
