This idea can be applied to logistics as well. In the past, logistic cost has been defined in purely monetary terms. However, as not only in the EU but also in the USA and other countries became more and more aware of environmental problems ,for instance because of climate change, air pollution, noise and accidents, environmental considerations has been taken in logistics kfield. This is how Gree

fuel through partial oxidation. The coal is fed into a high-temperature pressurized container along with steam and a limited amount of oxygen to produce a gas. The gas is known as synthesis gas or syngas and mainly consists of carbon monoxide and hydrogen. The gas is cooled and undesirable components, such as carbon dioxide and sulphur are removed. The gas can be used as a fuel or further process

Six million dollars is a small amount in the gasoline market. The United States consumes well over 20 million barrels of oil a day. Replacing some of this oil with ethanol seem, so far, to be the most feasible solution to reducing the country’s dependence on petroleum.
Today, most cars on the road can use a mix of 10 percent ethanol and 90 percent gasoline. But the car industry is rapidly chan
