Coal waste is excluded from the list of hazardous and toxic waste categories (B3 Waste). This abolition is contained in Government Regulation (PP) Number 22 of 2021 concerning the Implementation of Environmental Protection and Management and is one of the derivative regulations of the Job Creation Law. The hazardous waste category is Fly Ash and Buttom Ash (FABA) or solid waste generated from the coal burning process in steam power plants, boilers and industrial furnaces for raw materials, as well as for the construction sector. "Utilization of non-hazardous waste as raw material, namely the use of special non-hazardous waste such as coal fly ash from PLTU activities with minimal CFB (Ciraiating Fluidi" zed bed) boiler technology is used as a construction raw material to replace pozzolanic cement, "the regulation reads as quoted by Merdeka.com, Friday. (12/3/2021).

Article 459 paragraph 3 (C) explains that coal fly ash from the steam power plant (PLTU) and other activities is not considered B3 waste, but non-hazardous. Meanwhile in Article 54 paragraph 1 letter a PP 101/2014 concerning B3 waste management, it is explained that coal dust from PLTU activities is categorized as B3 waste. "Examples of the use of hazardous waste as a substitute for raw materials include the use of B3 fly ash from the coal burning process in the steam power plant (PLTU) which is used as a substitute for raw material for alumina silica in the cement industry," the regulation said. However, the Beleid was revoked through PP 22, along with four other PPs. It is known that the PP was signed by Jokowi on February 2, 2021.

Previously, Pertamina Energy Institute (PEI) Vice President Hery Haerudin said electricity demand in Indonesia was projected to increase to 4.5 percent per year in the Green Transition or GT energy development scenario (focusing on renewable energy). Based on the results of the PEI analysis, electricity demand will increase by 3.7 percent per year in the Business As Usual (BAU) scenario, or in a stable business condition of the energy business actors in Indonesia. "The installed electricity capacity also has the potential to reach 268 Giga Watts by 2050, in the GT scenario, with the share of renewable energy reaching 56 percent," Heru said in the Pertamina Energy Webinar 2020, Tuesday, December 8, 2020. Heru explained, the greatest potential for additional renewable energy capacity comes from the types of heaven and wind energy which reach 34 GW in the Market Driven scenario (MD and 67 GW in the Green Transition (GT) scenario in 2050. Meanwhile, geothermal energy is projected to reach 10 GW and 17 GW. in each of these scenarios. "This is due to solar and wind energy because in terms of cost, it is the cheapest at this time, followed by hydro and geothermal energy," he explained. With the projected increase in electricity and gas demand, the addition of coal generating capacity is predicted to slow down, or grow with a minimal value of only 8 GW in 2050 (GT scenario). The gas generator will continue to increase with a potential capacity of up to 70 GW in the GT scenario. "Electricity production from EBT (new and renewable energy) also increases up to 56 percent in the Green Transition scenario," he said.
