Notweed Paper is the first paper brand that takes advantage of the environmental problem, caused by invasive plants, and turns it into an opportunity for paper-making.
Unexpected solutions for invasive plants
Novel ecosystems across the globe are greatly altered by the thriving nature of invasive plants. Their forceful spread causes big distress to local authorities and land owners. Instead of working towards their eradication, Notweed Paper uses their abundant biomass for creating a unique line of paper products.
Paper that nurtures biodiversity
In order to protect forests and their diverse residents, we need to think of sustainable alternatives to standardised paper production. By replacing virgin wood fibers with the prospering Japanese knotweed plants, we aim to contain the spread of invasive species and foster life in our precious forests.
Together with friends we gather on degraded sites around the city and forage the feral weeds – our local source of plant fibres.
Reviving local production
The harvest is carried to the paper factory, which stands in the vicinity of our picking spots. The fibrous stems are milled into pulp and carefully crafted into paper sheets.
Treat yourself with unique paper products
Notweed Paper is a recyclable and biodegradable paper, made without any bleaching. Its sandy shades and natural textures bring an ideal opportunity to design beautiful stationary, invitations, packaging or artworks that let you expose your environmental responsibility in a distinctive and meaningful way. [ To display your contribution to green paper choices, a certificate of origin and a paper mark are included with your purchase. ]
