Equipment Requirements to Study Mixing of Fibrous Materials

by Gregory T. Benz Introduction There are many sources of organic fibers that can be used as feedstock for biofuels and renewable chemicals. The author has tested many lignocellulosic materials for fluid flow and mixing characteristics. Examples include corn stover, ground wood, switchgrass, various types of cane, beet pulp, paper mill waste, municipal solid waste…

Feedstock Evaluation & Risk Analysis

As feedstock is the single largest expense in any biofuels operation, feedstock evaluation and the risks associated with the different feedstocks must be carefully delineated.   As opposed to other types of agricultural based operations, biofuels sees new feedstocks being constantly introduced to the  renewable energy market.  The risks, costs and benefits of each feedstock must…

Biofuels Overview

The terms “biofuels” and “renewable biofuels” refer to a fuel produced by some biological process like agriculture or anaerobic digestion, as opposed to fossil fuels (coal and petroleum) which are produced through a geological process which come from prehistoric biological matter. After years of research and development, many biofuels now exist. They are normally classified…

Landfill Consultants

What do landfill consultants do? In 1986, there were 7,683 MSW landfills in the United States. By 2009, there were just 1,908 active MSW landfills nationwide: a 75 percent decline in disposal facilities in less than 25 years.[15] However, this number is deceptive. Much of the decrease is due to the consolidation of multiple landfills…
