Biomass Sourcing, Storage, and Preparation

Many biomass-based projects show that problems frequently occur due to over-simplified assumptions as to the sources, delivering quality and quantity, storage and reclaim requirements, and pre-processing of biomass to meet the process feedstock specifications.  If your region needs an alternative to landfilling and seeks not only recycling of the easy stuff – clean paper, plastics, and…

Heat Transfer Issues in Mechanically Agitated Fermenters

Heat Transfer Issues in Mechanically Agitated Fermenters? Aerobic fermentation generates a significant amount of heat, which must be removed to maintain a constant temperature. The main heat sources are metabolic heat generation, agitator power input, and compressor power input. Removing the heat is made more challenging by the fact that fermenters are operated at mild…

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…

Renewable Natural Gas

Renewable Natural Gas is produced from organic materials at farms, landfills, wastewater treatment plants, and food waste systems.  As an alternative to fossil fuel natural gas, RNG systems with good RNG technology can reduce greenhouse gas emissions. RNG is a manufactured product developed from the raw, methane-containing biogas produced by anaerobic digestion, in turn, a…

Due Diligence in Securing Renewable Feedstocks

Due diligence is an important step for securing feedstock in any type of renewable fuels or renewable chemicals matter.  While due diligence experts in renewable fuels and renewable chemicals projects certainly have a wide variety of functions, the selection, and procurement of feedstock are normally early and high on the list.  This is especially true…

Agricultural Waste Expert

Farming is one of the largest industries in the world and generates significant amounts of agricultural waste. This waste has been targeted as a prime feedstock for the production of energy, fuel, and chemicals. It comes in two broad categories. One of the categories contains the materials left over from the production of crops. These…

Emerging Biofuels

Like any early-stage venture, having a solid pro forma at the beginning is essential for emerging biofuels projects. Some examples of developing and emerging biofuels might include advanced algae-based biodiesel or biofuels created using petroleum-like hydroprocessing or advanced biochemistry. They might also include biogas produced through anaerobic digestion of residues, and maybe even wood pellet…

Ethanol Expert

Ethanol experts are specialists that understand how to produce ethanol by fermentation of corn, milo (grain sorghum), sugar, or cellulose to ethanol.  This type of expert requires knowledge of feedstocks (corn, milo, cellulose), enzymatic conversion of feedstocks to sugars, and fermentation of the sugars to ethanol.  This expert should also be aware of the principles…
