While the most common crops used for ethanol throughout the world are certainly corn and sugarcane, there are an increasing number of crops being investigated and used in the industry. Amongst sugar/starch crops, sugarbeet and sweet sorghum have been the focus of much attention; cellulosic crops such as switchgrass, miscanthus, corn stover, poplar, and grass are the subject of increasing interest.
Currently, rapeseed (canola) is the dominant feedstock for biodiesel in Europe, and soybeans are the dominant feedstock for biodiesel …
Jatropha: Biodiesel and More
Jatropha seed oil is used in soaps, and energy for lighting and heating in subtropical and tropical areas where it is planted as living fences to stop soil erosion. Its biodiesel potential is being researched because the seeds contain from 25% to 40% oil.

Safety in Small-Scale Biodiesel Production
Introduction

Although the biodiesel manufacturing process is fairly straightforward, there are several aspects of biodiesel production that need careful attention to detail for a productive, safe, and environmentally sound practice. First, some chemicals used could pose serious risks to the operator or to the environment, unless the proper precautions are taken for storage, process safety, handling, ventilation, and use. Second, disposal of glycerol by-product and waste water generated from biodiesel production could cause environmental harm, unless …
New Uses for Crude Glycerin from Biodiesel Production
Introduction
Glycerol (also known as glycerin) is a major byproduct in the biodiesel manufacturing process. In general, for every 100 pounds of biodiesel produced, approximately 10 pounds of crude glycerol are created. As the biodiesel industry is rapidly expanding, a glut of crude glycerol is being created. Because this glycerol is expensive to purify for use in the food, pharmaceutical, or cosmetics industries, biodiesel producers must seek alternative methods for its disposal. Various methods for disposal and utilization of this …
