In a world where deforestation directly leads to biodiversity loss, disrupts the water cycle, and alters rainfall, looking for alternatives to recycle or produce paper is more important than ever.
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a pollen-based paper that, after being printed, can be erased and reused multiple times without any damage to the paper.
The process of making pollen-based paper is similar to traditional soap-making, which is simpler and less energy-intensive. It begins with potassium hydroxide being used to remove the cellular components encapsulated in tough sunflower pollen grains, which are then turned into soft microgel particles.
