Waste Transportation Environmental Impact Using Life Cycle Assessment: Bibliometric Analysis and Systematic Review

The transportation stage contributes to greenhouse gas (GHG) emissions, which vary according to collection type and transportation system. The aim of this research is to identify the environmental impact of waste transportation vehicles using various fuels by reviewing the literature in various countries. This study also examines striking research trends and themes, critical elements, and evolution to provide future study direction. The Bibliometric method uses research trends and in-depth content analysis to identify the relevant and most influential articles. This study compares waste transportation using diesel fuel, compressed natural gas, biomethane, and pneumatic collection, finding that vehicles using diesel fuel had the highest environmental impact compared to others. Replacing diesel fueled vehicles with CNG fueled vehicles can minimize GHG emissions. Meanwhile, seen from a renewable electricity perspective, stationary pneumatic collection is a positive step towards more sustainable and environmentally friendly transportation and waste management.
