Jakarta (ANTARA News) – PT Semen Indonesia (Persero) Tbk, PT Semen Padang and PT Semen Tonasa utilize biomass as an alternative energy source to substitute the use of coal, as well as gradually reduce electrical energy consumption.
Related efforts to substitute the energy Semen Indonesia won the Primary Energy Award from the Ministry of Energy in appreciation of the company’s efforts to diversify energy by utilizing renewable energy biomass as an alternative fuel, as well as play an active role in the development of new technologies and innovations in the field of energy.
This award once again proves the commitment and real work Semen Indonesia in implementing the concept of sustainable business, said Director of Semen Indonesia, Dwi Soetjipto in Jakarta, Monday.
Dwi explained, the cement industry is an energy-intensive industries, including coal consumption is not a renewable energy source.
“Through the utilization of biomass, we have the dual purpose of maintaining the sustainability of the environment and operating costs while increasing efficiency, which in turn can increase the profitability of the Company,” he added.
According to Dwi, the utilization of biomass is able to provide stimulus to the economy of the local community, as imported from the area around the plant, among others Tuban, Lamongan, Bojonegoro, and Rembang (Central Java).
“Utilization of biomass also serves to reduce greenhouse gas emissions to minimize the impact of global warming,” he said.
Dwi said, every year the company always increase the use of biomass as an alternative fuel to reduce the use of coal. Types of biomass used as an alternative fuel is rice husk, sawdust, coconut powder (cocopeat) and waste tobacco.
PT Semen Indonesia (Persero) Tbk is targeting the use of biomass as an alternative fuel for four-unit plant in Tuban, can gradually be increased to 3 percent of coal fuel needs an average of 2,000 tonnes per day.
The use of biomass can simultaneously reduce CO2 emissions by 15 034 tons of CO2 eq annually.
Another source of alternative fuel is waste being generated from community activities. PT Semen Indonesia in cooperation with the Government of Gresik and Tuban regency government for utilization of municipal waste as an alternative fuel that refuse derived fuel (RDF).
To realize the company took Japan Fero Engineering (JFE) and the New Energy Foundation (NEF) as partners. Potential urban waste that can be used up to 300 tons per day and began to be implemented following the operation of Tuban IV plant.
PT Semen Tonasa developing the use of sorghum as a biofuel. The company cooperates with PTPN XIV planting sorghum in an area of 1.9 hectares.
Gradually sorghum planting area will be increased to 20 in Pangkep, South Sulawesi and surrounding areas. Utilization of sorghum is expected to replace the use of coal, which will reduce the cost of production by 50 percent while reducing CO2 emissions.
Since February 25, 2011, the implementation of the CDM in Tuban and Tonasa factory has been integrated in the United Nations Frame Work Convention on Climate Change (UNFCCC). Furthermore, the verification stage Emmission Certified Reduction (CER) at the end of 2013.
Emissions are calculated by the amount equivalent to the substitution of carbon emissions (CO2) that is compensated through the mechanism of carbon trading credits (carbon credit trading). Potential revenue through transaction Certified Emissions Reductions or Certified Emission Reduction (CER) in 2011-2012 reached 60,000 CER, with a value of 1 CER equivalent of 1-5 euros.
In addition to biomass, currently the Company is developing technologies in the field of renewable energy the project Waste to Zero, utilization of municipal solid waste as an alternative fuel (Refused Derivative Fuel) and pProyek WHRPG (Waste Heat Recovery Power Generator) Tuban, gas use waste heat from the process combustion to generate electricity.
“We do not stop here, this time we are carrying out two projects at once, namely the use of municipal waste as an alternative fuel (Waste to Zero) and the utilization of gas waste heat from the production of a power plant with an output of 30 MW,” added Dwi ,
“The era of business today is the era of the matter and have a sense of belonging (sense of belonging) to the environment. For us in Indonesia Cement principle is a better environment for many, better achievement for the company. It is evident that energy management is well able to keep our nature while enhancing the company’s performance, “he said.
