𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 𝐏𝐁𝐎 𝐅𝐢𝐛𝐞𝐫 Origins and development of fiber Initially developed for military and aerospace applications in the 1980s, PBO fiber was introduced to the market by Toyobo under the Zylon® brand . Quickly adopted for its remarkable properties, it has been used in applications as varied as ballistic equipment, bridge suspension cables, and lightweight structural components. In the 1990s, its uses expanded to industrial sectors such as glass and aluminum , where it effectively replaced heavier or less efficient materials such as asbestos or metals under extreme temperature conditions. Composition and chemical structure of PBO PBO fiber, or poly(p-phenylene-2,6-benzobisoxazole) , belongs to the family of high-performance polymers. Its chemical structure is distinguished by extremely stable covalent bonds formed by benzene and oxazole rings. These bonds give the fiber exceptional molecular rigidity , explaining its superior mechanical and t...

Atlas Building Composites, a spinout of MIT, is on a mission to address both problems with a single solution. The company has developed an AI-powered robotic manufacturing platform capable of turning single-use plastics into durable building materials. The company emerged from MIT HAUS, a research effort in the MIT Department of Mechanical Engineering that’s short for “Home Architecture for Universal Sustainability.” Atlas uses waterless plastic recycling and large-scale composite additive manufacturing technology to make parts like home foundations, decks, and trusses for walls, floors, and roofs. “Our mission is to convert waste plastic pollution into durable composites to build 1 billion homes,” says Atlas chair and co-founder A.J. Perez ’13, MNG ’14, PhD ’23, who is also an MIT research scientist. “You can’t divorce these things from each other. We’re not here just to build homes, and we’re not here just to recycle plastic. The conventional way of building homes involves cutting do...

Omya launches Omyaprene™ 50 C, a new functional filler designed to help rubber manufacturers reduce carbon black consumption, lower the carbon footprint of their compounds, and support more sustainable formulations. "With Omyaprene™ 50 C, manufacturers can take a meaningful step toward reducing carbon black consumption and supporting lower compound carbon footprints, while continuing to meet demanding performance requirements," said Christophe Roux, Commercialization Manager Material Science Polymers - Europe, Middle East & Africa. Omyaprene™ 50 C has demonstrated the capability to replace up to 50 wt. % of virgin and recovered #carbonblack grades N550, N660, and N770 in selected rubber applications, including #EPDMcompounds , NBR/SBR flooring compounds, and #naturalrubber (NR) formulations. Laboratory and industrial evaluations conducted by #Omya have shown that it can maintain critical performance characteristics including tensile strength, compression set, elongatio...

If a foam can biodegrade, shouldn't it automatically be the better choice? Not necessarily. EPS became the packaging industry's workhorse because it's lightweight, durable, insulating and cost effective. Decades of manufacturing improvements have made it incredibly efficient. Biodegradable foams bring exciting environmental potential, but they face some tough challenges: -Higher production costs than conventional EPS -Limited composting infrastructure in many markets -Performance gaps in some insulation and protective packaging applications -Consumer confusion about proper disposal The reality is that sustainability isn't just about what a package is made from. It's about whether the entire system from...

The problem isn’t always workload. It’s how we think about it. Here are 5 laws that shape careers more than any strategy: 1/ Murphy’s Law → Anything that can go wrong, will go wrong  So build buffers. Assume friction. Plan for reality, not perfection. 2/ Kidlin’s Law → Writing a problem clearly solves half of it Most people feel stuck because their thinking is vague. Clarity reduces overwhelm instantly. 3/ Gilbert’s Law  → Ownership of a task means ownership of the outcome  Not effort. Not intent. Outcome. Accountability is what builds trust and reputation. 4/ Wilson’s Law  → Prioritise knowledge and intelligence, money follows Skills compound. Credentials fade. Capability is what sustains careers lon...
