  • cradle to grave Assessment of existing lignocellulose pretreatment technologies
    Current Opinion in Biotechnology, 2009
    Co-Authors: Leonardo Da Costa Sousa, Shishir P S Chundawat, Venkatesh Balan, Bruce E Dale
    Abstract:

    Pretreatment is considered to be a central unit process in a biorefinery to convert lignocellulosic biomass into fuels and chemicals, affecting all other operations in the process. A variety of technologies to pretreat lignocellulosic biomass are available today, which encompass a wide range of physical, chemical, and biological based processes. Among these, chemical based pretreatments are considered to be the most promising for future biorefineries. However, several key criteria regarding technical, economical, and environmental considerations should be critically analyzed when adapting these technologies for the nascent biorefinery industry. This review will discuss the most important pretreatment methods available today and will highlight key criteria for the development of a future ideal pretreatment.

  • uncertainty quantification in life cycle Assessments interindividual variability and sensitivity analysis in lca of air conditioning systems
    Journal of Industrial Ecology, 2017
    Co-Authors: Stephen A Ross, Lynette Cheah
    Abstract:

    Summary The life cycle environmental profile of energy-consuming products, such as air conditioning, is dominated by the products’ use phase. Different user behavior patterns can therefore yield large differences in the results of a Cradle-to-Grave Assessment. Although this variation and uncertainty is increasingly recognized, it remains often poorly characterized in life cycle Assessment (LCA) studies. Today, pervasive sensing presents the opportunity to collect rich data sets and improve profiling of use-phase parameters, in turn facilitating quantification and reduction of this uncertainty in LCA. This study examined the case of energy use in building cooling systems, focusing on global warming potential (GWP) as the impact category. In Singapore, building cooling systems or air conditioning consumes up to 37% of national electricity demand. Lack of consideration of variation in use-phase interaction leads to the oversized designs, wasted energy, and therefore reducible GWP. Using a high-resolution data set derived from sensor observations, energy use and behavior patterns of single-office occupants were characterized by probabilistic distributions. The interindividual variability and use-phase variables were propagated in a stochastic model for the life cycle of air-conditioning systems and simulated by way of Monte Carlo analysis. Analysis of the generated uncertainties identified plausible reductions in global warming impact through modifying user interaction. Designers concerned about the environmental profile of their products or systems need better representation of the underlying variability in use-phase data to evaluate the impact. This study suggests that data can be reliably provided and incorporated into the life cycle by proliferation of pervasive sensing, which can only continue to benefit future LCA.
