The Curious Case of Paper As Structure
Here are five creative explorations of paper as a building material:
Shredded Paper Board is a new composite material manufactured in the labs of Nottingham Trent University, comparable to MDF in strength. Dr Anton Ianakiev, Hooi Cheah and Dr Anthony Crabbe figured out a way to mix sodium silicate and shredded office paper to create compressed boards, which are currently being explored to build raised access floor panels.
PaperCrete is a form of fibrous cement made of re-pulped waste paper (old newspapers, prints, cardboards etc.) mixed with Portland cement and sometimes with sandy soil as an additive. The inherent hydrogen bonds in the microstructure of the paper give it strength. Its low carbon footprint, recycled nature, and low embodied energy make it a potentially useful alternative to regular concrete with subsequent experiments on its properties, standardization tests, and manufacturing processes.
Paper Brick is a promising building material given its mechanical and thermal performance for a lightweight brick made of recycled paper, binder and aggregate. It essentially involves kneading the binder-paper assembly consisting of sand, cement, and paper pulp powder mixed homogeneously with water in ten minutes - which also makes the material energy efficient while it's prepared.
Newspaper Wood completes the cycle of wood to paper and then from (news)paper back to a form of processed material that has physical properties and the aesthetic of wood. The innovator of the material, Mieke Meijer, uses a unique method of layering to manufacture and fold techniques for reinforcement in this material that has wood-like structures from old and recycled newspapers.
The Honext Board is an incredibly innovative material made from ‘cellulosic waste’ - essentially the fibres from recycled and reused paper waste that would otherwise be disposed of in a landfill or burnt. It’s a highly durable, sustainable, non-toxic, and resilient material that can be crafted with tools and joineries identical to those used for wood.
