Marves – Bontang, Coordinating Ministry for Maritime Affairs and Investment, Ministry of Energy and Mineral Resources, Ministry of Environment and Forestry together with the Indonesian Forest Entrepreneurs Association (APHI) and the Indonesian Coal Entrepreneurs Association (APBI) worked together to prepare a pilot project for biomass and coal exploitation during their visit to the mine reclamation site of PT.Indominco Mandiri, Bontang, East Kalimantan, on Tuesday-Wednesday (24-25 May 2022).Indonesia has committed to reducing Greenhouse Gas (GHG) emissions by 29% from the business-as-usual scenario of GHG emissions in 2030. One of the efforts made is the co-firing of coal-fired Steam Power Plants (PLTU) with biomass to reduce costs. fuel, reducing emissions while still increasing combustion efficiency.Biomass co-firing is also part of efforts to meet the New Renewable Energy (EBT) mix target of 23% by 2025. It is known that PLN is targeting 52 PLTU co-firing locations spread throughout Indonesia.For that, 9 million tons/year of biomass is needed by 2025.Plt.Assistant Deputy for Management of Forestry Products and Environmental Services (PPK and Jasling) Dirhansyah Conbul revealed that the potential resources that should be utilized for blending biomass and coal have not been implemented because there are no policies or regulations governing their use."The market potential is quite wide, in principle, industries that have been using coal can do co-firing with biomass to reduce emissions," he explained.More Plt.Asdep Dirhan said that the Coordinating Ministry for Maritime Affairs and Fisheries initiated the preparation of cross-ministerial Working Groups to encourage the exploitation of biomass and coal to accelerate the achievement of GHG emission reduction targets and EBT mix targets.IMM Mining Coordinator, Era Tjahja Saputra said his party welcomed the efforts of the Coordinating Ministry for Maritime Affairs to encourage the implementation of biomass and coal pilot projects.Currently IMM is transforming to become a green industry, IMM's PLTU has also simulated the use of biomass for co-firing.Currently, wood chip off takers are not only PLTU PLN, but also industries that have independent PLTUs as well as other industries that use coal such as cement and fertilizers.Wood chip biomass will improve the quality of coal boiler exhaust emissions through significant ash reduction.In addition, the negative impact of H2SO4 emissions from the combustion process can be reduced.Forestry Expert Prof.Dr.Dede Hermawan, who is also a member of the Biomass and Coal Working Group, explained that to meet the demand for biomass wood chips from PLN's PLTU participating in the co-firing program, Perhutani will supply wood chips in the form of sawdust."It is planned that the location of the supplier and offtaker is in a location that is close enough to ensure the availability of a sustainable supply of biomass with good economics," he added.On the same occasion, mine reclamation expert Dr.Irdika Mansur said that mining land that is being reclaimed also has the potential to be used for biomass.Mining companies are doing reclamation, requiring regular thinning to ensure the quality of local plants.However, at this time the plants cut down in the thinning process cannot be utilized."Many mining companies that have independent PLTU (mouth of the mine) around coal mines can utilize wood waste from thinning plants to do cofiring with coal, and this does not reduce the existing natural forest into production forest (transfer of function)," said Dr.Irdika.Plt.Asdep Dirhansyah explained that the partnership between forest entrepreneurs and coal entrepreneurs can build an upstream biomass industry, where the HTE production can be used as wood chips with sizes that match the needs of the PLTU boiler and then blended with coal with the appropriate composition.His party encourages the implementation of a pilot project for coal exploitation partnerships in potential locations."The criteria include the location of the power plant which is close to port access to reduce transportation costs, the required licensing criteria, partnerships with existing forestry businesses, and the criteria for utilizing energy wood waste in both the land clearing process and thinning in the reclamation process."concluded Plt Assistant Deputy Dirhansyah.Communication Bureau of the Coordinating Ministry for Maritime Affairs and InvestmentNo. SP-168/HUM/ROKOM/SET.MARVES/V/2022Save my name, email, and website in this browser for the next time I comment.© KEMENKO MARVES RI |made with passion and dedication
