Life Cycle Assessment of Sweet Sorghum as Feedstock for Second-generation Biofuel Production [PDF]

open access: yes, 2017
There exist few life cycle assessments (LCAs) in the literature that focus on the second-generation biofuel production from sweet sorghum, a non-food-source feedstock that offers several advantages in terms of farming requirements compared to corn or ...

Dissecting Extreme Price Fluctuations in Mineral Fertilizers: Regularities and Co‐Movements in Light of Global Food Security

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Extreme swings in food prices can put food security at risk. Fertilizer prices are among the main drivers of food prices. This work explores the recurrent behavior of the extreme global fertilizer price fluctuations underlying food price dynamics.

Washington Biofuel Feedstock Supply under Price Uncertainty [PDF]

open access: yes
Biofuels, as alternative transportation fuels, are now being used globally. Taking advantage of in-state feedstock supply is an efficient way to stimulate in-state biofuel industries and the local economy.

Biofuels are dead: long live biofuels(?) – Part one

open access: yesNew Biotechnology, 2008
Beleaguered by criticisms, and abused by politicians for ecological target-setting, biofuels are in their darkest hour. But their bringing to trial should remind us - yet again - of something else: the highly questionable sustainability of most of modern agriculture. Is this the end of biofuels?

The Role and Impact of Rooftop Photovoltaics in the Norwegian Energy System under Different Energy Transition Pathways

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study investigates the impact and cost‐competitiveness of rooftop solar power in a highly hydropower‐driven northern energy system toward 2050. The role of rooftop photovoltaics (PV) is assessed under different energy transition pathways and through a sensitivity analysis aiming to disclose important barriers to PV investments in the energy system.

Is a Malleable Active Site Loop the Key to High Substrate Promiscuity? Hybrid, Biocatalytic Route to Structurally Diverse Taxoid Side Chains with Remarkable Dual Stereocontrol

open access: yesAngewandte Chemie, EarlyView.
A highly stereoselective, dynamic reductive kinetic resolution (DYRKR) entry into myriad Taxotere‐like side chains with Clostridium acetobutylicum alcohol dehydrogenase (CaADH) enzyme is reported. Follow‐on cross couplings expand the structural diversity of the library (36 total examples).

The Brazilian biofuels industry [PDF]

open access: yesBiotechnology for Biofuels, 2008
Ethanol is a biofuel that is used as a replacement for approximately 3% of the fossil-based gasoline consumed in the world today. Most of this biofuel is produced from sugarcane in Brazil and corn in the United States. We present here the rationale for the ethanol program in Brazil, its present 'status' and its perspectives.

Integrated Green Biorefinery for the Production of Anthocyanins, Fermentable Sugars, and High Pure Lignin from Miscanthus × giganteus

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Integrated production of pigments, fermentation sugars, and pure lignin has been investigated for the creation of profitable biorefinery developments. Choline chloride‐based natural deep eutectic solvents possess unique solvent capabilities to interact with plant cell wall components to disintegrate lignin‐carbohydrate complex.
