Cellulosic Hydrolysis Reactors

Cellulosic materials, such as corn stover, cane, switchgrass, timber waste, municipal solid waste, etc., can be processed into fuels and renewable chemicals. Broadly speaking, there are two main methods: pyrolysis and hydrolysis. The former is relatively independent of feedstock but happens at high temperatures and may have yield losses due to breakdown of the molecules […]

Biotechnology Experts

What does a biotechnology expert or consultant do?  Biotechnology is the use of some biological processes for industrial or other purpose, like the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.  There are many types of bio technologies, including medical (such as vaccines and antibiotics), agricultural (such as pest resistant crops and […]

Biofuels Expert

What does a biofuel expert do? Biofuels are a replacement for petroleum-derived fossil fuels.  They are derived from biomass and made via processes that meet lifecycle requirements to meet the definition so reducing greenhouse gas emissions.  There are currently three generations of biofuels,  the first generation is from sugar derived from food crops like corn and includes ethanol and ethanol along with fuels derived from further […]

Waste-to-Energy Technology Expert

What does a Waste-to-Energy (WTE) Technology  expert or consultant do?  Waste-to-Energy (WTE) is based on thermochemical and biochemical processes to produce alternative/clean energy from the waste feedstocks, such as biomass waste, municipal solid waste (MSW), industrial waste, sewage sludge, used tires, and other. Waste-to-Energy (WTE) technologies relate to Gasification, Plasma Enhanced Gasification, Steam Reformation, Pyrolysis, […]

Emerging Biofuels

Within biofuels, examples of emerging technologies are: torrefaction to produce biocoal slow pyrolysis to produce biochar fast pyrolysis to produce pyrolysis oil and biochar hydrothermal carbonization to produce hydrochar hydrothermal liquefaction to produce biocrude stream treated to produce black pellets gasification to produce producer gas and/or syngas. With such early-stage ventures, an important early task […]

Circular Economy and Waste Conversion

By Zoltan Kish, Ph.D. The increasing amount of waste is one of the most demanding problems facing the world, which creates global environmental challenges. Worldwide, 2.12 billion tons of waste are generated annually, and it is expected to rise at the current trend [1]. The most of the trash ends up in landfills emitting harmful […]

Celebrating Canada’s 150th: A Short History of the Biofuel Industry in Canada

 By Dr. Gerald Kutney, Lee Enterprises Consulting The 150th anniversary of Confederation on July 1st is a time to reflect upon the country’s achievements; this article covers the evolution of the Canadian biofuel industry – including gaseous, liquid and solid biofuels, and biomass power – from 1867 to 2017. The foundations of the biofuel industry in […]

Biomass Pyrolysis Comes of Age

By Dr. Lorenz Bauer, Lee Enterprises Consulting After many years of development biomass pyrolysis is finally maturing as a commercial technology.  Pyrolysis is not incineration.  The goal is to use heat in the absence of oxygen to convert the biomass to a more useful form while preserving as much of the carbon as possible.  The water […]

The King of Biofuels – A Guide to Pyrolysis’ Progress and Prospects

Biofuels Digest recently invited two of our noted biofuels experts, Dr. Lorenz Bauer and Dr. Terry Mazanec, to lead webinars on the field of pyrolysis and to discuss its progress and future prospects.  Dr. Bauer presented Part 1 and Dr. Mazanec presented part two. For Lee Enterprises Consulting, Dr. Bauer handles bio oil upgrading, catalytic […]
