Create a global community that aims to transform Japanese knotweed waste into circular and sustainable materials for different industries.

Long description

The Japanese knotweed plant is considered one of the worst weeds in the world and has caused serious damage to the natural and built environment. 

Due to its ability to spread easily creating a hostile environment, it is classified as an invasive species in more than 15 countries. In the UK, it is considered a controlled waste, so after its removal, it must be taken to a licensed landfill for its disposal. The plant is widely spread in the UK, costing the economy approximately £166 million per year.

In fact, it is a global issue. Native to Japan and China, this “problematic plant” is located in 43 countries. With the aim of reversing the concept of wastage created by humanity, this project aims to reduce the negative impact this species is creating by using design as a tool to turn something negative into something positive. Through a zero waste and circular manufacturing approach whereby nothing is left behind, the plant proved to be a precious local source of raw material for at least 8 industries. By adding value to this abundant source of raw material, more local and self-sustaining production systems can emerge.  With the aim to transform its waste into materials, the project intends to share this model of local and circular production with other cities, thus building an interconnected network capable of acting locally and promoting more self-sufficient cities.
