Biomass Feedstock Contracting

Biomass feedstock contacting, to determine feedstock availability and reliability, is an essential component of any system of renewable energy production.  A key to success in this component of the operation is knowing the essentials of forward contracting and hedging of the biomass feedstock so that material is continually available and ready to use.  Contracting for…

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…

Anaerobic Digesters Worldwide

Anaerobic digesters worldwide are becoming big business. While implementation is often very capital cost intensive, the benefits of waste remove and greenhouse gas reduction certainly provide long term social and financial benefits.   Anaerobic digestion is being increasingly implemented worldwide as businesses and communities increasingly turn wastes, like animal waste and sewage sludge, into energy to…

Renewable Energy Agricultural Feedstock: Optimum Harvest

Determining which renewable energy feedstock harvesting system is optimal for the agriculture based feedstock is the most important first step in total feedstock logistics system.  In turn, this step must be able to provide the feedstock to the biomass processing plant in the best possible form to enable correct and efficient processing.  Once the harvesting…

Renewable Biofuels

The production of renewable biofuels and advanced biofuels in the U.S. still is in its infancy, with significant growth potential. These fuels —  made from living or previously living substances, such as agricultural products (soybeans, corn, sugar) and fast-growing algae — only represent eight percent of 2017 U.S. transporation fuel use, according to the U.S.…

Renewable Energy

What is a renewable energy?  First, an energy source that is not renewable is finite.  Energy sources like petroleum, natural gas, and nuclear fuel are all finite.  No more is being made.  Once they are used, they are gone.  On the other hand, renewable energy is any form of energy that can be produced from…

Life Cycle Analysis

Conducting a “life cycle analysis” – determining the cradle-to-grave carbon footprint and emission profile of a project and its raw material input and product output streams — is becoming increasingly common for companies that are developing new bioeconomy technologies and products. The benefits of this process go beyond its potential for providing a compelling demonstration…

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…
