In a recent article published in Advanced Sustainable Systems, researchers developed an all-natural alternative to plastic straws using a top-down molecular welding approach. This straw is made from de-lignified natural wood infused with chitosan, resulting in a flexible, moldable material that can be shaped as needed.​​​​​​​ Plastic straws are widely used consumer products, prompting significant efforts to develop biodegradable alternatives to replace petroleum-based plastics. However, existing options like polylactic acid and paper straws come with notable drawbacks, making them less-than-ideal substitutes. To effectively replace plastic straws, there is an urgent need for biodegradable, environmentally friendly materials that offer both mechanical durability and water resistance. …Overall, the researchers successfully prepared microplastic-free, ultra-strong, hydro-stable, and biodegradable all-natural bendable straws through a top-down method using earth-abundant natural wood and edible chitosan.

A 13-storey high-rise approved for development in Sydney is slated to become the tallest commercial mass timber building in New South Wales. The building has been designed by architecture and urban design practice Tzannes for property developer NGI Investments. …The weight of the building was a significant consideration during the design process. The structure needed to be lightweight as the site is located above subterranean railway tunnels. Tzannes’s approach for addressing has involved transferring the load from the building’s western side to a central core using a hybrid concrete and steel structure. This system then supports 12 timber commercial floors, with 11 levels rising above the load transfer structure and one suspended below. According to a communique issued by Tzannes, “all timber and steel elements will be crafted for future disassembly and reuse.”

A designer and former technology scout, PaperShell cofounder and CEO Anders Breitholtz sought to unlock solutions for steering the design industry toward a circular economy. …Following some exploration with advisory service Material ConneXion, Breitholtz teamed up with fellow PaperShell cofounder Mathieu Gustafsson in 2018 to begin tests on a new paper alternative. PaperShell’s material possesses a superior strength to wood through intensive compression molding that merges and cross-links paper fibers and bio-resin. The process reintegrates hemicellulose into the substrate to create a dry prepreg that is then cut into blanks and stacked under a large steel press for shaping and trimming. Production waste is turned into biochar as well, setting the basis for a circular economy. “You get a component which is 100 percent biogenic. There’s no fossil carbon inside. It’s just natural materials,” Breitholtz says. “By pressing it really, really hard the paper sheets become a homogeneous material.” 

BRISBANE, Australia — A new Gabba, built right across the road from the old cricket ground, could break records as the world’s largest timber stadium. Architecture firm Kirk Studio’s proposal appeals to the 2032 International Olympic Committee’s sustainability strategy by using renewable construction material. The result would be a 60,000-seat “Gabba West” stadium across Main Street from the existing Gabba. …Speaking to this masthead, architect Richard Kirk said using timber would make Gabba West one of the most environmentally friendly stadiums in the world. “The commitment made in the bid for the Olympics is that it would be six-star Green Star, and a core part of that is we should be replacing up to 40% of the structure with renewable materials,” he said. “And the only renewable building material is timber.” …Using timber would also reduce the stadium’s weight – allowing it to sit more easily above both the Cross River Rail and Clem7 tunnels.

Unveiling its new design, the Indore Nagar Parishad Assembly Hall in India illustrates a thoughtful approach to modern civic interior design through the use of western hemlock – blending aesthetics, functionality, and environmental consciousness. …Recognizing the various benefits of wood and its aesthetic appeal, Ar. Puneet Pandey of VIMA sought a material that could contribute to the intended atmosphere of the space, particularly by incorporating natural elements which can reduce stress and improve cognitive performance through biophilic design principles. The hall needed to be more than just a meeting space; it needed to be aesthetically appealing and contribute to the overall environment, maintaining the sanctity of its purpose. Having established a prior relationship with FII India through trade events and educational seminars, Ar. Puneet Pandey sought the expertise of the FII India team to assist with material selection and project implementation.

Architecture studio PPAA has unveiled the first building in the country with a structure constructed predominantly of mass timber, claiming it is a “milestone in Mexican architecture”. Located in an industrial complex in Querétaro, Mexico, the building has a structure made almost completely from engineered wood products, prefabricated and assembled on-site, with only the stairwells made of metal. PPAA founder Pablo Pérez Palacios told Dezeen that he chose mass timber for its sustainability, reduced labour costs and the speed of construction, though he noted that mass timber is currently more expensive in Mexico than other common building materials such as steel or concrete… The facade was made from polycarbonate sheets called Danpal, which were chosen to increase the project’s light diffusion, weather resistance and energy efficiency.

Swedish startup Adsorbi has secured €1mn to ramp up production of a cellulose-based material that sucks up pollutants from the air. Bordes and Grenda, the chief researchers, originally wanted to develop new ways to protect works of art from harmful pollution. But in the process, they discovered a way to turn cellulose from Sweden’s abundant forests into an air purification material with wide-ranging applications… The substance — which looks like little, white pieces of sponge — promises a better, greener alternative to activated carbon, the current market standard. Adsorbi claims its product lasts longer, doesn’t release any hazardous organic compounds back into the air, and is water and fire-resistant. Plus, the material has half the carbon footprint of activated carbon, the startup said.

One of the amazing things about plants is their ability to change shape in response to environmental stimuli such as light and moisture, even without a brain or central nervous system. Now, a new generation of biomaterials is similarly able to respond to environmental cues… The research started off with cellulose – a material found in plants that changes size in line with humidity levels around it… In terms of borrowing from nature, this adaptive material ticks all the boxes. First, it is made from plant raw materials. Cellulose is an abundant natural material found in the cell walls of plants, fruits, leaves, and vegetables. Second, the cellulose is processed in ways that are inspired by the makeup of biological organisms. In short, it is both a biomaterial (made from biological stuff) and a bio-inspired material (designed based on biological mechanisms).

STOCKHOLM, Sweden — A yellow crane hovers above a building site in Sickla, a former industrial neighbourhood that’s home to one of Stockholm’s biggest real estate projects. But instead of delivering concrete, it’s manoeuvring giant chunks of wood to construction staff working in sub-zero winter temperatures. This is the beginning of what Swedish property developer Atrium Ljungberg describes as “the largest mass timber project in the world.” On the outskirts of Sweden’s capital, construction of ‘Stockholm Wood City’ began in October and is set to provide 2,000 new homes by 2027. The company’s core goal is to improve the sustainability of construction projects. Building with wood instead of concrete and steel would… help offset half of Europe’s construction industry emissions. …Atrium Ljungberg also hopes the wooden buildings themselves will boost locals’ wellbeing. There is already a small but growing body of academic research linking wooden materials with lower stress levels.
