The extent of ex-coal mining area which reaches around 8 million hectares is an environmental problem itself that needs to be addressed. Energy plantations are an effective solution for the reclamation of the former coal mine land for more details, you can read here. Reclamation of ex-coal mining land is a form of responsibility of the coal mining company. Reclamation should be carried out as well as possible, not only symbolic and ceremonial, so that the effects of environmental damage can be minimized. Efforts to reclaim ex-coal mining land is not an easy thing and requires a lot of time and money, so it is not surprising that many avoid this responsibility. The best solution is to tackle the problem while generating both economic and environmental benefits. The production of wood pellets with wood raw materials from the energy plantation is a surefire solution to overcome this environmental damage as well as economic benefits.Recently, the government launched a cofiring program for a number of coal powerplants in Indonesia. In 2020 the cofiring program has been initiated with a target of 37 coal powerplants and by the end of 2020 it has been reported that 20 coal powerplants have been implemented. While in total there are 114 units of coal powerplans owned by PLN (Indonesia state owned electricity company) that have the potential for cofiring spread over 52 locations with a total capacity of 18,154 megawatts (MW) with a target completion of 2024. Consisting of 13 coal powerplant locations in Sumatra, 16 coal powerplants locations in Java, Kalimantan (10 locations), Bali and Nusa Tenggara (4 coal powerplants unit), Sulawesi (6 locations) and Maluku and Papua (3 coal powerplant locations). Meanwhile, the cofiring ratio ranges from 1-5% of biomass with an estimated biomass requirement of 9-12 million tons per year. Cofiring is the easiest and cheapest effort for coal powerplant to gradually use renewable energy, especially biomass with main purpose of CO2 reduction. Currently, there is also a national standard for wood pellets (SNI wood pellets) for the purposes of cofiring and for more details, please read here. The use of biomass fuels, especially wood pellets, is a carbon neutral scenario that needs to be continuously improved. The biomass fuel will save the environment and not increase the earth's temperature, for more details read here.
