New low-cost, one-step path to coffee biodiesel uncovered by UK research team

New low-cost, one-step path to coffee biodiesel uncovered by UK research team

May 14, 2017 |

In the UK, researchers at Lancaster University led by Dr Vesna Najdanovic-Visak have developed a one-step system for making biodiesel from spent coffee grounds.  The team found they are able to combine the processes by using just methanol and a catalyst – removing the need for hexane altogether and saving on chemical waste. In addition, […]

Lancaster University make breakthroughs in biofuel production from spent coffee grounds

May 10, 2017 |

In the UK, although a small number of businesses are using spent coffee grounds to make biofuels, researchers at Lancaster University have found a way to significantly improve the efficiency of the process- vastly increasing biofuel from coffee’s commercial competitiveness. The chemical engineers have consolidated the existing multi-stage process into one step (known as in-situ […]

Breakthrough in biodiesel: Duonix Beatrice reaches commercial-scale, with signature advances in cost-reduction, feedstock flexibility

September 22, 2016 |

The most important technological advance in biodiesel in recent years has reached commercial-scale in Eastern Nebraska, with the startup of the Duonix Beatrice biodiesel plant, which is and the first commercial-scale application of Benefuel’s innovative ENSEL technology. ENSEL technology is capable of converting a range of lower cost feedstocks such as recycled cooking oil and […]

Malaysian researchers develop algae biodiesel using nanocatalysts

Malaysian researchers develop algae biodiesel using nanocatalysts

July 7, 2016 |

In Malaysia, researchers from the Universiti Putra Malaysia have developed a methodology to produce biodiesel from algae using nanocatalysts and synthesized through a calcination–hydration–dehydration technique. The nano-CaO catalysis impact was investigated in a two-step transesterification of triglycerides from crude Jatropha oil as a biodiesel along with other reaction parameters such as catalyst ratio, reaction time, […]

Indian researchers develop smaller-scale UCO biodiesel units

Indian researchers develop smaller-scale UCO biodiesel units

June 16, 2016 |

In India, student researchers at IIT Delhi have developed a small-scale UCO biodiesel unit that will allow individual UCO producers like hotels and eventually households to produce their own fuel affordably. The transesterification time for the batch process system is only about an hour, and can be adapted for using oilseed feedstocks rather than just […]

Where did biofuels technologies come from?

Where did biofuels technologies come from?

June 1, 2016 |

By Gerald Kutney. VP, Lee Enterprises Consulting Special to The Digest In the modern world, fuels are often equated with fossil fuels: coal, oil and natural gas.  However, fossil fuels only came into their own during the 20th century. From the time of the caveman until the early Industrial Revolution, biofuels – namely wood and […]

REG’s Rolling Thunder: What did not kill them (falling oil prices), made them stronger

April 4, 2016 |

At 8:30am, there’s a standing daily meeting of the key traders in Gary Haer’s sales group at REG headquarters in Ames, Iowa. And they’re not kidding. Everyone stands. For 15 minutes there’s the rat-a-tat-tat of rumor, fact, competitors, pricing, spreads, the who’s selling what and where, the buying and selling of diesel, renewable diesel and biodiesel across North […]

Iranian engineers develop biorefinery for castor without need for fossil-based methanol  

Iranian engineers develop biorefinery for castor without need for fossil-based methanol  

September 29, 2015 |

In Iran, chemical engineers have found a way to produce biodiesel from castor oil without the need for extra petrochemical methanol, using a biorefinery set-up. Producing biodiesel from vegetable oils is not completely renewable, as the standard transesterification process requires the use of methanol, which is usually produced from petrochemical sources. The researchers, Hamed Bateni […]
