Biofuel from olive stones

RTE Stuttgart  - Spanish scientists from the Universities of Jaén and Granada have developed a method to gain from olive stones biofuel. The advantage of this method lies in the fact that no processed foods and no additional land will be claimed, the researchers write in the Journal of Chemical Technology & Biotechnology "(published online).

In the processing of olives a year fell four million tonnes of seeds as waste, which could be used for the production of bio-ethanol. "The low costs incurred for the export and processing, the olive stones make an attractive raw material for the production of biofuel," said the researcher Sebastián Sánchez. Made of 100 kilograms of olive stones could be obtained 5.7 kg ethanol.

The researchers acknowledged that the accumulating total quantity of olive stones as compared to other waste materials in agriculture and forestry is relatively low. If you develop for any agricultural waste similar procedures, one could achieve a significant energy gain.

olive oil guide

This thorough investigation and appreciation of olive oil from food writer Krasner (Kitchens for Cooks), encourages cooks to delve deeper into the pleasures of this versatile staple. The author first gives an in-depth summary of olive oil: like wine, olive oil can be classified by type and grade-and, like grapes, the flavor of olives is affected by soil and climate as well as methods of production. Krasner then discusses kitchen basics, equipment and ingredients and tips for variations, substitutions and labor-saving measures, as well as a section of alphabetically arranged resources, mostly Web sites, some with phone or address. While an entire cookbook on recipes for olive oil may seem excessive, Krasner does offer such dishes as Tapenade, and Chickpea, Tuna, Olive, and Goat Cheese Salad. For main courses, she includes recipes for Charcoal Grilled Butterflied Leg of Lamb, Turkish Style, and Seared Scallops on Chickpea Crepes. Illustrations by Krasner and photographs by Ann Stratton enhance this presentation.
