>> So who knew? The manufacture of cooking oil involves hexane, a  
>> solvent that separates the oil from crushed seeds.  Hexane is a  
>> volatile organic compound found in gasoline.  Hexane is also a  
>> degreaser used in the printing industry.  It dissolves glues,  
>> varnishes, and inks.  Aside from the ick factor of having the same  
>> compound used to dissolve glues and inks pop up in the production  
>> of your bake sale items, hexane is a pollutant that contributes to  
>> smog and greenhouse gas emissions.
>>
>> This is where Queens University of Ontario, Canada comes in.   
>> Researchers there have discovered a new energy efficient way to use  
>> the greenhouse gas carbon dioxide to help separate oils from seed  
>> and vegetable crops including corn, canola, peanut safflower,  
>> sunflower, and soybean.  That’s the sustainable twofer we’re so  
>> fond of: a new twist on a conventional process that reduces  
>> negative impacts while providing a remedy for additional problems  
>> as well.
