Sector progress

Assessment of Costs and Benefits of Flexible and Alternative Fuel Use in the U.S. Transportation Sector, Progress Report One, DOE/PE-0080, U.S. Department of Energy, Washington, D.C., Jan. 1988. 

Alcohol sulfates were first obtained either by the reaction of olefins with sulfuric acid or by sulfation of alcohols produced by hydrogenolysis of oils and fats with sulfuric acid. With the advent of petrochemistry and the progress of chemistry and chemical engineering, alcohol sulfates and their derivatives have become one of the most important surfactants and are produced in large amounts using techniques different from those originally used. They are based on a wide range of alcohols and have found applications in almost all domestic and industrial sectors. 

The project will progress in stages, beginning with a waste audit carried out by an audit team. The audit team consists of a waste audit expert, a sector specialist, a financial expert, an economist/ marketing expert, and an expert in product life-cycle assessments. The audit team also supports the project in its different stages. 

Pesticides were created as a new, progressive and effective technology for agriculture and other sectors. At first glance, these expectations were justified to some degree. Today we can say that this advance was a two-edged sword. 

Brazilian cement plants are relatively modem due to the country s more recent industrialization in comparison with many other countries. For example, the average energy consumption per tons of cement produced in Brazil is 112 kWh/t, while in the United States this is around 140 kWh/t. The efforts of companies in the sector have achieved significant progress in terms of more efficient production systems with lower energy consumption. At the same time, the use of additives mixed with clinker, such as blast furnace slag, also has helped reduce C02 emissions per tonne of cement, because this pollutant is formed during the production of clinker. 

There is much technological progress in each of these sectors, but the future lies in their integration. The decisive factors that will give systems the edge over their competitors are...
