Biomass Supply Chain Expert – Agriculture

What is an agricultural biomass supply chain expert? Simply put, it is a person that understands the dozens of issues that will affect the production of the tens of thousands of tons of feedstock that a project needs to be profitable as it produces a fuel or chemical.  The expert should know how to get […]

Renewable Energy Expert

What do renewable energy experts or consultants do?  Renewable energy sources (RES) are ones that capture their energy from existing flows of energy, from on-going natural processes like sunshine, wind, flowing water, biological processes, and geothermal heat flows. Unlike fossil fuels such as petroleum that are exploited at rates that may deplete these resources in […]

Hydroprocessing Expert

What does a hydroprocessing expert or hydroprocessing consultant do?  A hydroprocessing experts can design process using hydrogen to upgrade biofuels and renewable chemicals.   Hydroprocessing is used to remove oxygen, sulfur, and nitrogen from biomass-derived feeds and renewables to produce drop-in feeds.  A consultant can aid in the selection of appropriate catalysts, predict yields and hydrogen […]

Advanced Biofuels Expert

What does an advanced biofuels expert or consultant do?  When we speak of “advanced biofuels”, we are referring to second generation biofuels – as opposed to first generation biofuels.  First generation biofuels are generally made from food crops like virgin vegetable oils (soybean oil, canola oil, etc.) or sugar cane. Although there are exceptions, advanced […]

Make Lenders Love Your Construction Contracts

By Charles Loos, Lee Enterprises Consulting By the time a developer seeks non-recourse financing for a biomass project, the contracts for construction and major equipment procurement have usually been pre-negotiated and are on hold awaiting notice to proceed.    Prospective lenders then scour these contracts for defects, paying particular attention to inconsistencies between the various contracts.   Clean […]

Lignocellulosic Biomass Deconstruction

By Dr. Bernard Cooker, Lee Enterprises Consulting Cheap, plentiful lignocellulosic biomass (LCB), consisting of cellulose, hemicellulose and lignin, is deconstructed to release useful chemical intermediates in the bioeconomy. These include glucose from cellulose, glucose and other sugars from hemicellulose, and oxygenated benzene derivatives (OBTX) from lignin. Reviewed here are recent published developments of note in LCB […]

Sustainable Polyurethanes and the Bio Economy

Sustainability has become a key concern in polyurethane industry.   Reducing the environmental impact of polymers by replacing fossil derived carbon, using more environmental friendly processes and reducing and recycling the carbon used either directly or indirectly is a corporate goal of many producers. The use of biomass to produce value added chemicals for polymer synthesis […]

Ionic Liquids: A Key Enabler of Biomass Processing?

By Dr. Lorenz Bauer, Lee Enterprises Consulting Potential Of Ionic Liquids For Biomass Pretreatment The explosion of interest in using biomass to produce chemicals and fuels has motivated a renewed search for improved methods for pretreatment that enable efficient conversion of the raw materials.   The molecules in cellulosic materials, and particularly lignocellulosic material, are intertwined and […]

The Industrial State of Biofuels Technologies

By Dr. Gerald Kutney, Lee Enterprises Consulting A myriad of biofuel technologies exist, but which ones are truly industrial processes? The question is not always easy to answer. And one must define what is meant by an industrial process. To facilitate this task, three classifications of industrial status are utilized: Established – modern facilities are numerous, […]
