Biological Hydrogen Gas Production From Food Waste As A Sustainable Fuel For Future Transportation, Pitiporn Asvapathanagul, Leanne Deocampo, Nicholas Banuelos Jul 2022

Biological Hydrogen Gas Production From Food Waste As A Sustainable Fuel For Future Transportation, Pitiporn Asvapathanagul, Leanne Deocampo, Nicholas Banuelos

Mineta Transportation Institute

In the global search for the right alternative energy sources for a more sustainable future, hydrogen production has stood out as a strong contender. Hydrogen gas (H2) is well-known as one of the cleanest and most sustainable energy sources, one that mainly yields only water vapor as a byproduct. Additionally, H2 generates triple the amount of energy compared to hydrocarbon fuels. H2 can be synthesized from several technologies, but currently only 1% of H2 production is generated from biomass. Biological H2 production generated from anaerobic digestion is a fraction of the 1%. This study aims to enhance biological H2 production …


Evaluation Of Sustainability Determinants To Develop A Sustainability Rating System For California Infrastructure Construction Projects, Joseph Kim, Patricia Mccarthy Jun 2022

Evaluation Of Sustainability Determinants To Develop A Sustainability Rating System For California Infrastructure Construction Projects, Joseph Kim, Patricia Mccarthy

Mineta Transportation Institute

This study evaluates the important sustainability determinants that affect factors’ success in meeting their sustainability goals when conducting infrastructure construction projects in California. The study implemented the online survey method to evaluate the sustainability characteristics that infrastructure industry professionals currently are aware of under the current situation in California. A data set of 25 validated survey responses is used for statistical data analysis using analysis of variables, Kruskal-Wallis tests, and two sample t-tests. The analysis results showed that the median response values for the six major sustainability categories do not show any significant difference. The results also showed that no …
