The worldwide motivation to reduce environmental emissions through the inclusion and creations of renewable products and process has made that woody biomass play an important part in this change due to it is considered one of the most plentiful and low-cost reserve for biofuels and carbon based materials. The estimation of the environmental, social and economic aspect in bio-based product and companies is a critical and unclear topic. Currently, producers are struggling with the challenges and trade-offs related to different materials that traditionally have been primarily made from fossil fuel. Inquires about the real sustainability performance and conversion economics of bio-products and processes require to be addressed. On the other hand, one of the major challenges faced by bio-based companies is their own estimation of sustainable impacts in accordance to the governmental regulations. To do so, the Environmental, Social and Governance (ESG) attributes are considered as the most suitable indicators of how companies could describe a sustainable research or project development, and how they play a key in the business strategies and economics. Thus, this study intended to evaluate different analytical approaches of sustainability characterization for bio-based systems.The global growth in energy demand with the combination of the existing cumulative levels of environmental pollution, is actually determined to the transition for alternative and renewable energy sources. Torrefied biomass is considered as an alternative material to substitute coal without the need for costly renovations to the current coal operating plant. Hence, the first chapter of this study delivers an economics and environmental life cycle analysis (LCA) of the torrefied biomass at different operational conditions. To do so, this methodology uses an integrated process model to obtain the key parameters for the potential environmental and economic benefits of the product compared with coal and natural gas. Results suggest that as initial view, by torrefaction process with other sources, this is highly affected for the GHG emissions, which are controlled by the combustion process for power generation. Opposite outcomes are presented if biogenic carbon is considered in the analysis. On the other hand, according to the tornado analysis, operational temperature is one of the important parameter that make impact either on the greenhouse gas emissions than variable cost and net present value. This will determine the extra utility fuel and feedstock required.The use of wood for railroad ties has been historically attractive in the United States over the past. Benefits such as their precise toughness and springiness, comparative lightweight, and ease on the manufacturing and installation are the reason for that. Opposite to this, concerns as a natural resource, dimensional instability due to moisture changes, susceptibility to biodegradation, weathering, and fire resistance make the use of wood still challenging. Consequently, wood modifications attempts have been applied over the years in order to overcome these obstacles. On the other hand, the use of concrete material is currently debated due to the high CO2 impacts present during the production process but longer life time and carbonation effect make this material also attractive to use. The application of technical changes is highly dependent on both the features of the technologies themselves and the characteristics of the sustainability context including the environmental, social and economic assessment. Therefore, a complete analysis is required for decision-making process. Environmental full-cost accounting (FCA) is a novel analytical framework that describes ecological and human health impacts of products and processes using financial measures. The main goal of the second chapter was the application of the FCA methodology for the comparison of a series of chemically treated wooden and concrete railroad crossties. For all product, production of the treatment chemicals and the crosstie, use, and disposal phases were involved along with amount of emissions generated, and associated health and environment costs. Two alternative end of life (EOL) scenarios were analyzed energy recovery and disposal in a landfill. Results shows that the EOL scenario for treated crossties govern when environmental and social costs were defined. In contrast to this, concrete crossties, where the production stage is the main contributor. Wood treatment utilizing copper-chrome-arsenic (CCA) signifies a worst case EOL scenario due to the high costs associated with atmospheric emissions of arsenic and CO2. Finally, depending on how biogenic CO2 is treated, concrete or furfuryl alcohol treated wood had the lowest environmental price.
