The Hop Project

This project is an exploration on the use of agricultural byproducts from hop farming as a new material source. After harvesting the hop flower for beer production, the rest of the plant is burnt or composted. The long stems of the plant have been observed to be a rich source of fiber, with high cellulose content.

With a holistic approach to our relationship with natural materials, the project aims to experiment and research all the possibilities - which are many - of this so-called byproduct. Homemade experiments with handmade techniques were conducted with the bark, the bast fibers, the natural dye and the inner pith.

Other experiments are being conducted in collaboration with Wageningen University, where a novel degumming method for hop fibers is being tested.

By using agricultural waste as a material source, no new raw material needs to be planted. There is no deforestation or overloading of the Earth. Using the byproducts from farming as a source of new material is the most sustainable way to go. This project has to goal to show that it is possible to use agricultural waste as a sustainable and accessible material source and make it mainstream.
