On December 6, 2016, EPA held a hearing on its proposed Renewables Enhancement and Growth Support rule. The proposed rule would update the regulatory structure to allow biofuel producers to process and convert biomass at different facilities, update fuel regulations to allow for more high-ethanol fuel blends in flex fuel vehicles, and permit cellulosic biofuels to be produced from new feedstock sources. Testimony provided by Growth Energy and the Renewable Fuels Association (RFA) focused on the impact of the proposed rule on the development of the E15 market and strengthening ethanol flex-fuel provisions. Geoff Cooper, the senior vice president of RFA, stated that RFA was opposed to EPA establishing a quality survey program to collect and analyze ethanol flex-fuel samples, and highlighted the different treatment between E10 and E15 regarding volatility. Chris Bliley, the director of regulatory affairs for Growth Energy, also pushed EPA to resolve the vapor pressure relief issue, stating that the proposal would isolate E15 as the only ethanol-blended fuel without Reid Vapor Pressure (RVP) relief in conventional areas. Bliley supported the development of cellulosic biofuels through the use of biointermediates and new pathways, as well. More information on the proposed rule is available in the BRAG blog post EPA Announces Public Hearing For Proposed Renewables Enhancement and Growth Support Rule. The proposed rule was published in the Federal Register on November 16, 2016. Comments are due by January 17, 2017, at 5:00 p.m. (EST).

Increasing Lettuce Coloration with LEDs
Using LED grow lights in plant production is a relatively new branch of science. In vertical farming where artificial light sources are used in closed environment it is important to collect data about the individual plant species to be able to produce the right spectrum and light intensity for vegetative and generative growth. Light spectrums can also be used to manipulate the plants growth cycle for example in plant breeding (see blog post: Light Approaches To Speed Up The Generation Turnover) or secondary...
5 Things you may not know about CO2
There is a lot known about carbon dioxide (CO2) in its natural form as it exists in the Earth’s atmosphere as a trace gas. We know that as human beings we need this colourless, odorless gas to live and breathe. But you might not know, it’s also used in a commercially manufactured form in many products and services we use and see everyday. Paul Kimberley owner of Point Safety has installed many of Analox’s CO2 monitors for several different applications which has opened his eyes to the range...

Transgenic fish are ready for us. Are we ready for them?
After decades of regulatory and legal challenges, AquaBounty aims to bring genetically engineered salmon to U.S. and Canadian markets next year. On a hill above the cold waters around Prince Edward Island, technicians painstakingly create fertilized Atlantic salmon eggs that include growth-enhancing DNA from two other fish species. The eggs will be shipped to ponds in the high rainforest of Panama, where they will produce fish that mature far more quickly than normal farmed salmon. More than 20 years after...
The impact of low-flow season on source drinking water quality, Rosetta branch, Egypt
The present work was conducted to document the problems raised regarding low-flow in the Rosetta branch, Egypt and to develop management options to protect drinking water sources. The water quality was monitored during low-flow periods at four drinking water intakes. Results showed an increase in electric conductivity (EC), ammonium (NH4), nitrite (NO2), phosphate (PO4), and total organic carbon (TOC) during the low-flow period. EC ranges from 454 to 1,062 μS/cm and the mean value is 744. Ammonium ranges from...
