Producing diesel fuel from vegetable oil has been a boon to the transportation fuel industry. A drawback is that glycerol is left over after the conversion of triglycerides in the oil to the fatty acid methyl esters that make up the fuel. Researchers have been on the lookout for ways to use the now abundant glycerol, which does not burn well itself and is usually treated as waste. Using a life-cycle analysis approach, a team . . .
