Life Cycle Assessment Of Polylactic Acid Biopolymer Industrial Waste Management Techniques In Belize, Dennis J. Newby
Life Cycle Assessment Of Polylactic Acid Biopolymer Industrial Waste Management Techniques In Belize, Dennis J. Newby
Theses and Dissertations--Civil Engineering
In January 2020, the Government of Belize enacted an Implementation Strategy and Action Plan to phase-out single-use plastics and to transition to products like bioplastics. This work investigated the environmental effects of using alternative waste management techniques to manage polylactic acid biopolymer (PLA) waste by using life cycle assessment (LCA). The following treatment options were compared: landfill, landfill expansion, cogeneration, and anaerobic digestion. The landfill and landfill expansion processes both had a global warming potential of 0.01 kg of CO2 eq. per kg of PLA waste managed compared to the cogeneration and anaerobic digestion processes -0.03 and -0.06 kg …

Evaluation Of Liquid Ice Melting Additives For Winter Maintenance Applications, Erin Lammers-Staats
Theses and Dissertations--Civil Engineering
Winter weather can often pose difficulties for transportation agencies as they work to clear roads of snow and ice quickly so that motorists can travel safely and efficiently. Kentucky has made efforts to maximize efficiency within its winter maintenance program by focusing on optimized equipment usage and personnel time management. This study’s objective was to evaluate novel anti-icers and calculate how their performance compared to the current performance of brine and calcium chloride mixture. New brine additives claim to offer better results, but there is very little guidance about how to systematically evaluate new anti-icers. The author developed a testing …
