Burning gas and propane for cooking, water heating and space heating in California homes and businesses creates 10% of the state's greenhouse gas emissions. It also releases pollutants indoors.
Compostable packaging is a type of biodegradable packaging designed to break down alongside natural waste. It's usually made of plant-based materials, like corn syrup, cellulose, or paper, that decompose without leaving toxins behind.
Researchers at the Norwegian University of Science and Technology and the University of Tokyo have made a prototype of botanical cement made of desert sand and plant-based additives in hopes that it can be used to build houses and roads. Once mixed, the team adds tiny pieces of wood together and presses them all with heat to produce the cement.
Thermal modification is not a new invention, but its relevance has increased as expectations around performance, sustainability, and predictability have tightened. Developers, architects, and contractors are no longer just asking whether timber looks good or performs well initially. They want to know how it behaves after ten, twenty, or thirty years, and how much risk it introduces into a project once the scaffolding is gone.
When you think about building a house, what materials come to mind? Brick, wood and metal all come to mind; there are also some very distinctive glass houses out there. (Even if their occupants should refrain from throwing stones - though honestly, that's a good tip for indoor living in general.) A group of MIT researchers have come up with a very different way of making buildings, and it's one that also addresses an ongoing waste issue."We've estimated that the world needs about 1 billion new homes by 2050. If we try to make that many homes using wood, we would need to clear-cut the equivalent of the Amazon rainforest three times over," explained AJ Perez, who conducts his research in the MIT Office of Innovation. The title of a paper written by Perez and his colleagues - "Design, Manufacture and Testing of Structural Trusses Using Additively Manufactured Polymer Composites" - gives a sense of the solution that they have in mind.
Rather than representing a simple return to the past, this renewed interest reflects a broader reconsideration of how architecture engages with materials, local resources, and environmental conditions.
What began as a modest brief for a young and growing family soon evolved into a considered renovation that reimagines an existing Barwon Heads home. The original house had endured several unsympathetic alterations over the years, leaving it disjointed and built to a poor standard.
