Cost assessment of biomass coal fuel on air pollution and coal consumption reduction

Abstract

The use of coal as an energy source in the industrial sector has been quite massive, but the negative impact has not been a serious concern. We realized that the use of coal had caused pollution, including air pollution from coal-burning processing and water and soil pollution from the coal solid waste (fly ash and bottom ash), which not be appropriately managed. This study aims to assess the beneficiary of utilizing the unburnt carbon as co-firing in boiler industrial compared with air emission impact—the unburnt carbon mixed with municipal solid waste treated firstly to be briquette. The briquette was called Biomass Coal Fuel (BCF), and it was used as coal substitution of 10-15%. The cost of air pollution calculation referred to the Ministry Environmental Regulation Number 13 of 2011. We have compared the cost of air pollution between before and after BCF substitution. Meanwhile, the beneficiaries were calculated from the reduction of coal consumption. The result showed that emissions cost just approximately 4-5% of the beneficiaries due to reductions in coal consumption that about 145.656 – 218.484 million rupiahs per year. The factory can use this beneficiary to improve air emission controlling and support environmental conservation.
