Abstract

Domestic limestone industries need to prepare for the introduction of a paid allocation according to The 4th emission trading system. The limestone industry must reduce its greenhouse gas (GHG) emissions through process improvements (such as fuel conversion and increase in kiln efficiency) and system improvements (such as reflecting purity of raw materials and lime kiln dust factors). In addition, the limestone industry is currently classified within the same category as the cement industry. Therefore, when allocating emission allowances for greenhouse gas, it is possible that a low adjustment factor will be applied for the limestone industry due to differences in the industrial scale, raw materials, and product characteristics. The limestone and cement industries should thus be classified as two separate industries. Since unslaked lime and light-burnt dolomite are essential materials in a number of domestic industries, governmental support is essential to become a carbon-neutral and sustainable industry.

국내 석회 소성업은 온실가스 배출권거래제 4기 (유상할당) 도입에 따른 대비가 필요한 상황이며, 석회석 산업에서 온실가스 감축을 위한 방안은 주로 기술적인 것과 제도 개선을 통한 방법이 있다. 공정개선을 통한 직접적인 감축은 연료전환, 신식 소성로 도입 등이 있으며, 제도 개선을 통한 감축안은 온실가스배출량 산정 시 원료 및 제품의 순도를 반영하고, 포집되지 않고 배출되는 석회 킬른 먼지(Lime Kiln Dust, LKD)의 재탄산화율을 고려하는 방법 등이 있다. 현재 석회 소성업은 시멘트 산업와 같은 업종으로 분류되고 있으며 온실가스배출허용량 할당 시 업계 규모와 원료 및 제품의 특성 차이로 낮은 조정계수를 부여받는 문제가 발생할 수 있기 때문에 이들을 별도의 업종으로 구분해야 한다. 소석회 및 경소백운석은 국내 각종 산업에서 필수적인 재료이므로, 탄소중립과 지속가능한 산업이 되기 위해서는 정부나 지자체 차원의 지원이 무엇보다 필요한 실정이다.
