Tesfamariam Mekete, from from the University of Illinois, has said:
- “Nematodes are a part of our soil systems …”
- “However, when it comes to potential crops for biofuel production, we simply don’t know which nematodes are present in these crops and at what levels.”

- “The advantage for our system compared to plants and algae is that all of the captured solar energy is converted to sugars, whereas these organisms must divert a great deal of energy to other functions to maintain life and reproduce …”
- “Our foam also uses no soil, so food production would not be interrupted, and it can be used in highly enriched carbon dioxide environments, like the exhaust from coal-burning power plants, unlike many natural photosynthetic systems.”
- “In natural plant systems, too much carbon dioxide shuts down photosynthesis, but ours does not have this limitation due to the bacterial-based photo-capture strategy.”
- “You can convert the sugars into many different things, including ethanol and other biofuels …”
- “And it removes carbon dioxide from the air, but maintains current arable land for food production.”

- “Biodiesel is a clean burning fuel derived from a renewable feedstock such as vegetable oil or animal fat.”
- “It is biodegradable, non-inflammable, non-toxic, and produces lesser carbon monoxide, sulfur dioxide, and unburned hydrocarbons than petroleum-based fuel.”
Researchers from the State University of Campinas, Campinas, SP, Brazil; have presented an article titled: “Biodiesel production from integration between reaction and separation system: reactive distillation process.” 1
The researchers from the State University of Campinas have also noted:
- “… an efficient process using reactive distillation columns applied to biodiesel production.”
- “Reactive distillation is the simultaneous implementation of reaction and separation within a single unit of column.”
- “Nowadays, it is appropriately called “Intensified Process”.”
- “This combined operation is especially suited for the chemical reaction limited by equilibrium constraints, since one or more of the products of the reaction are continuously separated from the reactants.”
- “This work presents the biodiesel production from soybean oil and bioethanol by reactive distillation.”
- “Different variables affect the conventional biodiesel production process such as: catalyst concentration, reaction temperature, level of agitation, ethanol/soybean oil molar ratio, reaction time, and raw material type.”
- “In this study, the experimental design was used to optimize the following process variables: the catalyst concentration (from 0.5 wt.% to 1.5 wt.%), the ethanol/soybean oil molar ratio (from 3:1 to 9:1).”
- “The reactive column reflux rate was 83 ml/min, and the reaction time was 6 min.”

Dr Timothy Devarenne, AgriLife Research scientist from Texas A&M University’s Department of Biochemistry and Biophysics, has said:
- “Oils from the green algae Botryococcus braunii can be readily detected in petroleum deposits and coal deposits suggesting that B. braunii has been a contributor to developing these deposits and may be the major contributor …”
- “This means that we are already using these oils to produce gasoline from petroleum.”

Finavera Renewables Inc has reported:
- ‘… all four of its wind projects, comprising a total nameplate capacity of 293 megawatts (“MW”), submitted to the 2008 Clean Power Call have been accepted by BC Hydro for award of long term Electricity Purchase Agreements (“EPA”).’
- ‘The four bid submissions were in response to BC Hydro’s Request for Proposals to help make British Columbia electricity self-sufficient by 2016, and meet demand using 90% of all new energy from clean domestic generation sources. The projects will provide clean, renewable power to more than 75,000 homes and are located in the Peace Region of British Columbia.

Vaughn Gangwish from Southwestern Biofuels Association has said:
- “Biofuels are an increasingly important part of our national energy policy as we make the transition from petroleum-based fuels to renewable ‘green energy’ technologies …”
- “The Summit provides leaders in the biofuels field the opportunity to exchange information and research as we collectively build a new industry.”
Southwestern Biofuels Association (SWBA) Annual Policy Summit – scheduled for April 13 and April 14 in Albuquerque, New Mexico.

Han de Winde, Professor of Industrial Microbiology, from Delft University of Technology’s Biotechnology Department has informed:
- “The fact that we now have a process for breaking down furans, not to mention one that can be successfully incorporated into other organisms, paves the way for removing these kinds of compounds during the production of second-generation chemicals and fuels from waste wood.”
- “This enables us to avoid the costly and environmentally unfriendly methods which are currently used to remove furans. That makes using wood waste as a sustainable raw material a much more attractive proposition.”
Scientists from Delft University of Technology have indicated that they have ‘… discovered that the bacterium Cupriavidus basilensis breaks down harmful by-products which are produced when sugars are released from wood. They also managed to incorporate the degradation process in bacteria which are in common industrial use. This breakthrough does away with the need to resort to costly and environmentally unfriendly methods for removing by-products, thereby boosting the appeal of waste wood as a sustainable resource.‘

- “Lignocellulosic ethanol is expected to be commercialised during the next decade as renewable energy for transport.”1
- “Competiveness with first generation bioethanol and with gasoline is commonly considered in techno-economic analyses for commercial stage.”
Researchers from Swiss Federal Institute of Technology, Bioenergy and Energy Planning Research Group, ENAC INTER GR-GN, Lausanne, Switzerland; have presented an article titled: “Techno-economic analysis of lignocellulosic ethanol: A review.”
The researchers from Swiss Federal Institute of Technology, Bioenergy and Energy Planning Research Group, ENAC INTER GR-GN, Lausanne, Switzerland; have also noted:
- “Several existing reviews conclude about the high spread of current and projected production costs of lignocellulosic ethanol due to the significant differences in assumptions concerning the following factors: composition and cost of feedstock, process design, conversion efficiency, valorisation of co-products, and energy conservation.”
- “Focusing on the studies in the United States of America and in Europe, the present review investigates the different natures of the techno-economic evaluations during the development process of the supply chain i.e., standard costing with respect to Value Engineering, and Target Costing based on the projected market price.”
- “The paper highlights the significant contribution of feedstock to the lignocellulosic ethanol production cost and the need to consider competition between different uses for resources.”
- “It is recommended the use of a value-based approach that considers sustainability characteristics and potential competition for resources complementarily to Target Costing and Value Engineering.”

According to a Release dated March 8, sourced from University of York, in England, United Kingdom:
- “… a team headed by Professor Simon McQueen-Mason and Professor Neil Bruce at York, and Dr Simon Cragg at Portsmouth reveal that the gribble digestive tract is dominated by enzymes that attack the polymers that make up wood. One of the most abundant enzymes is a cellulose degrading enzyme never before seen in animals.”
