Inventory review and environmental evaluation of first- and second-generation sugars through life cycle assessment.

In recent years, there has been a great movement towards the generation of knowledge related to the biorefinery concept. First-generation biorefineries bear the stigma of using arable land and edible crops for fuel instead of as sources of food and feed. However, second-generation biorefineries have not reached the level of full technical feasibility.

Assessing the environmental sustainability of glucose from wheat as a fermentation feedstock.

In recent years, the need to substitute fossil fuels with renewable biomass has been a key driver in the development of the biorefinery concept. One of the possible routes towards the development of bioproducts under this scheme is through a sugar intermediate. Sugars, such as glucose, can be produced through starch crops, for instance wheat.

Bottom-up approach in the assessment of environmental impacts and costs of an innovative anammox-based process for nitrogen removal.

In recent decades, the wastewater treatment sector has undergone a shift to adapt to increasing discharge limits. In addressing the evaluation of innovative technologies, it is necessary to determine the scale at which reliable and representative values of environmental impacts and costs can be obtained, ensuring that the system under assessment follows the direction of eco-efficiency. This study has evaluated the environmental and economic indicators of an autotrophic nitrogen removal technology (ELAN) from laboratory conception (1.
