Original story at MIT On the Indian subcontinent, the widespread burning of firewood, coal, agricultural waste, and biomass for energy disperses black carbon particulates into the atmosphere. These manmade aerosols not only pollute the air, but also form an “atmospheric brown cloud” that’s disrupting the local ...
Protective garments for medical, civilian safety and military applications range from disposable lightweight fabrics to multilayered fabrics and laminated barrier materials, depending upon the nature of the contamination that threatens the wearer. Usually, only full barrier garments, such as the Level A liquid splash protective garments provide full protection from aerosols, and this is due to ...
With World Environment Day approaching, I decided I really should poke my head above the parapet. As an environmental engineer it behoves me to add my bit about waste. Let me explain where I fit in. I work in the oil and gas business (boooo I hear you say). Well that aside, someone needs to work there to keep them as clean as possible! My forte is waste and water management and zero waste is the ...
When gas was discovered in the mid Sahara areas of North Africa in the 1990s Andy Ive was asked by BP to help set up the water and waste infrastructure for what amounted to four small towns 600 km into the desert. No local infrastructure at all existed for the waste and water to be produced by 2-3000 workers. IVE overcame sandstorms, extreme heat, poisonous snakes and patented a novel solution to ...
Chemviron Carbon have pioneered the use of specially selected activated carbons for the storage and delivery of compressed aerial gases such as carbon dioxide and nitrogen. There are many potential gas storage/delivery applications relating to this technology, including as an environmentally friendly alternative to traditional aerosol propellants - see attached article. The technique can also ...
There are over three billion aerosol cans manufactured in the U.S. annually, 60% of which are consumed by households. Many of the products contained in these cans, such as paint products, light lubricants, starting fluids, polishes and waxes, and cleaners, contain substantial amounts of volatile organic compounds (VOCs) as solvents and include flammable propellants. As a result, partially empty ...
Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...
