The US AF evolution
While alternative fuel use in the USA has risen at a significantly lower rate than its European counterpart, the increasing awareness and support for circular economy principles and alternative ways of disposing of various types of waste are resulting in an important change. This enables an increased flow of alternative fuels to the cement industry and generates a call for high-quality process engineered fuel. By Evolution Environmental Group, USA.
The past 25 years have seen a considerable increase in alternative fuel (AF) use in cement kilns. In 1990 the United States cement industry was using about the same amount of AF as its European counterpart (see Table 1). Since then, Europe’s cement industry has led the way in several areas, including average thermal substitution rates (TSRs) and technological development.
