Rather than solely using a bottom line (even a triple bottom line) and largely linear approach to growth and development, we must imagine, analyze and quantify how circular growth augments our conventional business models.
An international team of scientists has devised artificial silk that becomes a slim yet tough fiber, with help from a machine designed to mimic the spinning spiders do naturally. The silk isn’t quite as strong as the real thing, but the researchers have a few ideas for fine-tuning the technology so it can move a step closer to the market.
Carbon Clean Solutions built a plant in Tuticorin in southern India that captures carbon dioxide from its coal-fired boiler and converts it into soda ash. The commercial-scale plant, set to capture 60,000 tons of CO2 annually, does it so cheaply that it did not need any government subsidies.

Following an introduction to the origins of green chemistry and the E factor concept, the various metrics for measuring greenness are discussed. It is emphasized that mass-based metrics such as atom economy, E factors and process mass intensity (PMI) need to be supplemented by metrics, in particular life cycle assessment, which measure the environmental impact of waste and, in order to assess sustainability, by metrics which measure economic viability.
Researchers at Duke University have discovered that silver nanowires are able to achieve the desired level of conductivity for printed circuits without needing to be heated to the point where they would harm the less expensive substrates.
January 5, 2017 | San Francisco Chronicle Hairprint is the first hair care company to receive the Made Safe certification — an independent third-party nontoxic certification program that puts products through a rigorous screening to test for potentially harmful ingredients.
A new catalyst for breaking the tough molecular bond between carbon and hydrogen holds the promise of a cleaner, easier and cheaper way to derive products from petroleum, says a researcher at Southern Methodist University, Dallas.
