Dispersing sulfur into urea

A new technology demonstrated by Shell Sulphur Solutions (London; www.shell.com/sulphur) aims to incorporate micronized elemental sulfur (which provides nutrients to fertilized plants) into urea. The technology, UreaPluS, employs a patented emulsification technique that evenly distributes sulfur throughout the urea matrix,…

Making bioethanol directly from starch

Today, the cost of enzymes continues to make bioethanol uncompetitive as a fuel. Eliminating the need for amylases, which are used to hydrolyze starch into fermentable sugars, would be a key step toward reducing the operating costs for producing bioethanol.…
