New Feedstock Options and Trends Boost Biodiesel Production
Special to The Digest In the United States, efforts to replace fossil fuels with biofuels are gaining momentum, supported by growing public awareness, government programs and emerging waste-to-fuel technologies. The Environmental Protection Agency’s (EPA) analysis of the Renewable Fuel Standard (RFS) projected that several types of biofuels, such as biodiesel, could yield lower ...

RFS: There are no lost gallons to reallocate
In the final days before EPA issues the 2020 volumes for the federal biofuel mandate and makes a ruling on the supplemental proposal offered in October, it’s critical to acknowledge that all available data shows there are no “lost gallons” of ethanol that need to be reallocated as part of these announcements. If anything, the Renewable Fuel Standard (RFS) mandates should be ...

Top Products - Avoiding Explosions in the Chemical Industry With Nitrogen
High-Purity Raw Materials from the By-Products of Biodiesel Production Producing diesel from plant-based raw materials creates unwanted by-products. Glaconchemie takes such by-products off of biodiesel manufacturers’ hands and uses them to develop high-purity raw materials. Glaconchemie uses self-produced nitrogen to overlay the production steps during further processing. In Germany, ...

NBB Announces New Report On Biodiesel Benefits
On January 22, 2018, the National Biodiesel Board (NBB) announced that a new study on lifecycle energy and greenhouse gas (GHG) emission effects of biodiesel updates and reaffirms the benefits of using the renewable fuel. The report was published jointly by ANL, Purdue University, and the U.S. Department of Agriculture (USDA). Researchers gathered data on the energy and emissions from farming ...

The effect of mixing on fermentation of primary solids, glycerol, and biodiesel waste
In this study, the effect of mixing on volatile fatty acid (VFA) production and composition was investigated through running five identical bench-scale reactors that were filled with primary solid and dosed with either pure glycerol or biodiesel waste. Experimental results revealed that there was an inverse correlation between the mixing intensity and the VFA production. The total VFA ...

EIA Issues Short-Term Energy Outlook Report
On July 11, 2017, the Energy Information Administration (EIA) issued its June Short-Term Energy Outlook (STEO). EIA considered EPA’s recent rulemakings on the 2017 RFS volume requirements and proposed 2018 RFS volume requirements when developing its STEO for 2017 and 2018. Biodiesel production averaged 101,000 barrels per day (b/d) in 2016, and, according to EIA, is expected to ...

Assessing biodiesel quality parameters for wastewater grown Chlorella sp.
Microalgae are reported as the efficient source of renewable biodiesel which should be able to meet the global demand of transport fuels. Present study is focused on assessment of wastewater grown indigenous microalga Chlorella sp. for fuel quality parameters. This was successfully grown in secondary treated waste water diluted with tap water (25% dilution) in glass house. The microalga ...

How is biodiesel produced?
This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

Biodiesel Companies Can Thank BRAG For Cost Savings On CDR Reporting
As reported in last week's Update, EPA published its final rulemaking expanding the list of chemicals partially exemption from certain additional chemical data under the CDR. This action, which formally amended the list of chemicals that do not have to report the onerous downstream processing and use information under the CDR Form U, Part III, occurred because of the forward thinking actions of ...

Tom Vilsack Responds To Studies On Evolution Of Ethanol Production
On February 16, 2016, Agriculture Secretary Tom Vilsack responded to two recent reports on ethanol and renewable fuels. The first report was published by USDA and is on "2015 Energy Balance for the Corn-Ethanol Industry," and the second report comes from the University of Missouri Food and Agricultural Policy Research Institute (FAPRI) and is a "Literature Review of Estimated Market Effects of ...

Senate passes bill extending energy tax credits
On July 21, 2015, the Senate Finance Committee voted to pass a $96 billion package of tax extenders. The tax credits in the package include Individual Tax Extenders, Business Tax Extenders, and $16.4 billion in Energy Tax Extenders. The wind production tax credit, a $1.01 per-gallon production credit for second generation biofuels, energy efficiency credits, and a renewable electricity production ...

Case study - Managing complex energy systems
Introduction: Campus on a Renewable Mission The Chewonki Foundation owns and runs a school campus in Wiscasset, Maine that supports a high school program, a boys and girls summer camp, and an organic farm. Chewonki is an alternative school with a focus on environmental education and natural history. ch-classroom.jpgAs such, one of the Foundation’s goals is to teach its students about ...

Anaerobic treatment of crude glycerol from biodiesel production
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas ...

Australia reaches agreement to tax biodiesel and ethanol
On June 17, 2015, the Australian government made a bipartisan agreement to tax Australian-produced biodiesel and ethanol. Cleaner fuel grants for renewable and biobased diesel fuels will end by July 1, 2015, as will the Ethanol production grant. An excise rate on biodiesel will be phased in starting in 2015-2016 at zero percent, and will increase annually, eventually reaching 50 percent of the ...

Water-saving analysis on an effective water reuse system in biodiesel feedstock production based on
Chlorella zofingiensis fed-batch cultivationThe micralgae-based biofuel obtained from dairy wastewater (DWW) is considered a promising source of energy. However, this process consumes water due to the concentration of wastewater being normally too high for some micoralgae cultivation, and dilution is always needed. In this work, the cultivation of microalgae has been examined in non-recirculated water (NR) and recirculated water systems ...

Progress toward renewable fuel standard blending mandates
The White House is reviewing EPA's proposed rules to set the 2014, 2015, and 2016 Renewable Fuel Standard (RFS) requirements. The proposals are not currently publicly available, but EPA has committed to propose them by June 1, 2015, and to promulgate the 2014 and 2015 rules by November 30, 2015. EPA is required by law to issue the following year's RFS requirements by November 30 of the previous ...

Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends
Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

GHG balance of biodiesel production and consumption in EU
The promotion of biofuels as energy for transportation in the industrialised countries is mainly driven by the perspective of oil depletion, concerns about energy security and global warming. Nevertheless, the production of biofuels entails emissions to the environment coming from the different stages in the product life cycle. This paper evaluates the environmental impact of pure rapeseed ...
