Siloxanes — synthetic chains of alternating silicon and oxygen atoms — are widely used in personal care products, soaps, pharmaceutical formulations and other products, but are notoriously difficult to manage in production- and waste-fluid streams. Current approaches, including flaring and…
Pharmaceutical residues, particularly from antibiotics, are extremely difficult to fully remove from wastewater using traditional bulk-treatment methods, wherein antibiotic compounds are often only partially broken down. Even at trace amounts, antibiotic fragments can accumulate and wreak havoc on natural ecosystems.…
The widely used plastic polyethylene terephthalate (PET) can be depolymerized by reacting it with sodium hydroxide (NaOH) under strong mechanical impact from metal spheres in a ball mill. This type of mechanochemical route to recycling could alleviate some of the…
Advanced safety-instrumented system features minimize complexity, downtime and costs Chemical process plants must be vigilant when it comes to preventing accidents that have the potential to harm people, assets and the environment. While safety instrumented systems (SIS) reduce risks, they…
Among the major challenges facing efforts to chemically recycle common waste plastics is that many methods require a pure stream of a single type of polymer to be effective. Now, researchers at Northwestern University (NU; Evanston, Ill.; www.northwestern.edu), led by…
