My reading and Web activities bring me across many interesting and useful sites spanning a range of topics - chemistry, engineering, environmental issues, business, safety and quality. A few of my favorites are listed here to provide useful references, news and amusement for you. I have grouped them into these categories to make them more useful.
Chemistry - top resources for chemistry, organic chemistry, analytical chemistry, software, academic departments and whatever
Chemical Engineering - chemical and other engineering disciplines, academic departments and useful sites for engineers
Plant Safety, Process Safety, Laboratory Safety - leading sites for governement agencies, safety resources, training and guides
Manufacturing Efficiency, Quality and Sustainability - useful sites for energy efficiency, waste reduction, quality improvement and recycling of equipment and materials
Chemistry and Engineering Humor
Additional Resources - sites that have been useful to me, such as search engines, directories and portals, but don't fit any of my other categories
