Aumund increases its focus on conveying solutions for alternative fuels
The cement, steel and power industries are all energy-intensive, and still predominantly use fossil fuels in their processes releasing carbon dioxide which is damaging to the environment. At the same time these industries have to comply with increasingly stringent domestic and international legal requirements in order to reduce their CO2 emissions. Alternative fuels play a significant role in achieving these targets. The AUMUND Group is therefore convinced of the industry potential of alternative fuels...
At EU-level for example, the “European Green Deal” is regarded as the path to a sustainable EU economy. The overriding aim of the concept is that net greenhouse gas emissions are reduced to zero by 2050, and therefore the EU becomes carbon neutral. One of the most important initiatives of the Green Deal is the climate protection law that was introduced in March 2020. It requires EU emissions of CO2 to be reduced by 50 to 55 percent by 2030 compared to1990. On this journey, the use of all kinds of refuse as alternative fuels in energy-intensive industrial processes will become more and more important.
Alternative fuels can be divided into two groups. The first is biomass, which comprises among other things wood chips, wood pellets, sunflower seeds, coconut shells, soiled straw or hay and sewage sludge. Biomass is carbon neutral because when burnt, it is only re-releasing the CO2 that it had taken out of the atmosphere whilst growing or being produced.
The second large group is comprised of materials such as plastics, tyres, medical refuse, and waste from textile manufacturing, shredded paper or bone meal. In many countries it is no longer permitted to dump plastics, but as the possibilities for recycling are limited, plastic is an appropriate alternative fuel. A particularly suitable application is in the cement industry, where high-temperature processes break up the long chain hydrocarbons which are normally released by burning and can cause health hazards.
