According to The Australian Financial Review, the Australian start-up makes products from construction rubble otherwise destined for landfill, which is retrieved from building sites and pulverised before being transformed into stone paper.
Karst has since 2017 produced a range of notebooks made from a material known as 'stone paper', which requires none of the tree-felling or intense water use of traditional wood pulp paper.
At $25 for a single A5 size notebook, the environmental savings make Karst costly compared to A5 notebook competitors, available at Officeworks for as little as $2.
However, Karst co-founder Jonathan Tse said that corporate gifting from clients keen to show an eco-friendly face, including Dermalogica, Facebook and WeWork, had become a major revenue driver.
