The IEA estimates that biodiesel production used 17% of global vegetable oil ...
The so-called "third-generation biofuels", similar to second-generation biofuels with an emphasize on the use of algae and cyanobacteria as a source of biofuel feedstocks, have an additional advantage as they take up a relatively small fraction of space when compared to first and second-generation biofuel sources, and may also help to reduce seawater eutrophication.
Public outrage is mounting in China over allegations that a major state-owned food company has been cutting costs by using the same tankers to carry fuel and cooking oil – without cleaning them ...
Algae have very high growth rates compared to plants normally used to produce vegetable oil. Algae could potentially produce much more oil per area of land than current farming methods. [26] Producing vegetable oil this way could result in reduced deforestation and less competition for food production land.
Chinese state media on Monday criticized the state grains stockpiler Sinograin after local media reported that its fuel tankers were allegedly also used to transport cooking oil, sparking food ...
