This book looks at chemmotological solutions to important questions surrounding sustainability and environmental safety of transport — both key priorities within the global strategy of sustainable development. Bringing together expanded versions of selected papers presented at the 8th International Scientific-Technical Conference: Problems of Chemmotology – Theory and Practice of Rational Use of Conventional and Alternative Fuels and Lubricants, contributors present solutions to problematic questions, including choosing feedsk and technologies of its processing for manufacturing alternative fuels, development and implementation of measures for improving environmental safety of transport, minimizing exhaust gases emission from transport, introducing new solution or improvements in systems of fuels supply and infrastructure, and changes in legislative and regulatory base for fuels and lubricants use. This collection will be an invaluable reference for researchers, professionals, and students involved in alternative aviation fuels, transport engineering, sustainable transport development, and fuels and lubricants.
