Professor Veena Sahajwalla has spearheaded a groundbreaking initiative at the UNSW Sustainable Materials Research and Technology Centre in Sydney, Australia. She has introduced the concept of 'microfactories' that utilize waste plastics to create competitive products for the construction industry. By emphasizing profitability and performance, the microfactories produce personalized 3D-printed products like clamps, reducing costs and improving efficiency in construction projects. The innovative use of 100% plastic waste showcases a sustainable approach to manufacturing. Additionally, the expansion of the hydrogen revolution is evident in the development of clean hydrogen-powered vehicles like garbage trucks in Adelaide. Scott Brown of pure hydrogen anticipates a significant drop in fuel cell prices over the next decade, with major car manufacturers already investing in fuel cell engineering. This shift towards hydrogen-based clean energy is expected to revolutionize the transportation sector, leading to reduced pollution levels and promoting sustainability. The combination of advancements in 3D printing technology and the adoption of clean hydrogen energy signifies a promising future for environmentally friendly and cost-effective solutions in the construction and transportation industries.
