![]() You can simply dump the ash for landfill without any environmental problem. Īnother big advantage of using PKS charcoal is that the ash residue from combustion is not considered as hazardous waste. The complete report on the research can be read here. In addition to that, as CO2 generated from the charcoal is not counted as Green House Gases, use of charcoal has the possibility of CDM project. On the contrary, electrical energy saving was better than the case of coke from the high volatile content. The test use in EAFs showed that no bad effect, which was concerned at first from high volatile matter, was observed. Because of the low sulfur and ash content and high calorific value, PKS charcoal can be said better fuel than coke, so we can consider PKS charcoal is the bio-coke. As auxiliary energy in EAF, PKS charcoal simply outperforms coke. ![]() The research revealed that Palm Kernel Shell charcoal (PKS charcoal) is proven to be a better fuel in Electric Arc Furnaces (EAF). In 2010, Japan Consulting Institute took a bold action in search of a better, 'greener', and even cheaper alternative to replace fossil fuels like coke in steel making. However, this effort unavoidably raised environmental concern about deforestation. The program "Green Steel for the Brazilian Steel Industry" converted wood from Eucalyptus plantations into charcoal that will be used in steel making. Unfortunately, since the beginning of the Industrial Revolution, the burning of fossil fuels like coke and coal has contributed to the increase in greenhouse gases in the atmosphere from 280 ppm to 390 ppm, which caused greatly affect to the Global Warming.Īfter UN Climate Change Conference (COP15) in Copenhagen 2009, steel industry in Brazil proposed to replace coal and coke with charcoal in their high temperature furnaces. The coke is then acceptable for metallurgical purposes. Thus, we need to convert the coal into coke by destructive distillation method so that many of the impurities would come out of the coal. It remains mostly pure carbon with high calorific value which we called "Coke". ![]() Regular coal was tried, but it did not work well due to impurities in the coal, especially sulfur, are transferred to the metal. It takes about 100 kg of woods to make only 1 kg of steel. Charcoal works well but it would be too expensive to use in steel making. Wood charcoal was used in iron production up to about 1750.
