Opportunities from second-generation biofuel technologies for upgrading lignocellulosic biomass for livestock feed por Blümmel, Michael, Steele, B., Dale, B.E.

“…The work on second-generation biofuels (biofuels derived from lignocellulosic biomass) was motivated by reasons very similar to those of the early animal nutritionists: the abundance of lignocellulosic biomass and its content of polymerized sugars. …”

Emission balances of first -and second- generation biofuels: Case studies from Africa, Mexico and Indonesia por Frieden, D., Pena, N., Bird, D.N., Schwaiger, H., Canella, L.

“…This report examines and compares the greenhouse gas emissions of alternative first-generation and second-generation biofuel production pathways. The emissions balance analysed include greenhouse gas emissions from cultivation, land use change, processing and transport of biofuels. …”

Energy requirement assessment of bioenergy combine scenarios for cellulose based biofuel production : Version 1.0 por Perrino Martin, Elena

“…Second generation biofuels are a good alternative to replace fossil fuel in the transport sector, such as ethanol production from lignocellulose. …”

A global analysis of deforestation due to biofuel development por Gao, Y., Skutsch, M., Masera, O., Pacheco, P.

“…The report deals only with agriculture-based feedstocks such as sugarcane, soya, palm oil and jatropha, known also as first generation biofuels, because second generation biofuels from wood or other lignocelullosic materials have not yet been produced on a commercial scale. …”

Biomass use trade-off in cereal cropping systems in the developing world : overview por Erenstein, Olaf, Gérard, Bruno, Tittonell, Pablo Adrian

“…There is also increasing advocacy for second generation biofuels (ethanol production from hemi-cellulosic material) – albeit that for now these are unlikely to have substantial short term implications for most smallholders across large swathes of the developing world as biofuel use is primarily limited to traditional biofuel uses and mainly informal and small scale…”

A systemic study of biofuels in complex agriculture markets por Hilbert, Jorge Antonio

“…Carbon emitions of first and second generation biofuels need to be revised and closely look at in order to compare them in a fair way.…”

Evaluating the potential of culms from sugarcane and energy cane varieties grown in Argentina for second‑generation ethanol production por Ousmane Kane, Aissata, Arnoldi Pellergini, Vanessa, Espirito Santo, Melissa, Diop Ngom, Balla, Garcia, José María, Acevedo, Alberto, Erazzu, Luis Ernesto, Polikarpov, Igor

“…Herein culms from two different sugarcane (SC384 and SC724) and two energy cane varieties (EC3116 and EC3118) bred in Argentina were evaluated for sustainable production of second-generation biofuels and green chemicals. Changes in the biomass crystallinity, structure, and morphology introduced by pretreatments were investigated using X-ray diffraction (DRX), confocal laser scanning microscopy (CLSM), and scanning electron microscopy (SEM) techniques. …”
