Recyclability and Life Cycle Thinking in the Design of Vehicles and Work Machines

摘要

The main goal of increasing the recyclability of vehicles is to decrease theirenvironmental impact during their life cycle and to take the sustainable development of resources into consideration in the use of raw materials. In the life cycle assessment of a passenger car, its environmental impacts during its life cycle were found to be highest when it was in use. In an effort to cut down the amount and hazardous nature of exhaust emissions, vehicles have been improved technically in a number of ways, particularly through modifications of the engine. Fuel consumption has been decreased by reducing the weight of vehicles, which has led to a decrease in exhaust emissions. In addition to technical improvements, the dissemination of information on a more economical driving style has been a contributing factor in the lowering of fuel consumption. The hazardous nature of exhaust emissions has been mitigated by developing additives that replace lead for use in petrol. Additionally, new technology has been introduced in vehicles so as to curb the detrimental effects of exhaust emissions.
