1. Material av restprodukter från hampa till produktdesign
Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)Sammanfattning : This paper is a research through design that answers the question: How can the by-products from hemp production be utilized to create a sustainable material for product design?Hemp is the commercial crop that sequesters carbon dioxide most effectively in the world, but large amounts of bast fibers and hurd emerge as by-products ater cultivation for seeds, flowers, and leaves. These by-products can be difficult for farmers to manage as they require space for storage and often must undergo a lengthy production process before they can be converted into products. LÄS MER
