Abstract

The furniture industry has a high possibility to create value-added and a high potential to create new occupations due to the characteristics of the industry, which mainly consists of small and medium-sized enterprises (SMEs). However, the used furniture, which has sufficient reuse value, is also crushed and used as solid refuse fuel (SRF) recently. Besides, the number of waste treatment companies continues to decrease, and it occurs congestion of wood waste. As a way to solve the issue, a business model development of remanufacturing used furniture can be suggested as an alternative due to its high circular economic efficiency. Remanufacturing business including furniture industry creates positive effects in various aspects such as economic, environmental and job creation. In other words, remanufacturing is an effective recycling way to reduce input resources and energy in the production process. The results of economic analysis show that the expected annual revenue from the single worker furniture remanufacturing site was 104 million won which is 3.11 times more than the average income of a single-worker household in Korea and its B/C ratio was estimated about 30 which means high business feasibility. Revenue through furniture remanufacturing also showed 320 times higher than that of SRF production from the perspective of weight. In addition, it is shown that the GHGs reduction from the furniture remanufacturing is 2.2 ton CO2-eq. per year, which is similar to the amount of GHGs absorption effect of 937 pine trees or 622 Korean oak trees annually. Thus the results of this study demonstrate that it is important to adopt an appropriate recycling method considering the economic and environmental effects at the end-of-life stage.

가구 산업은 부가가치 창출의 가능성이 높고 중소기업이 주축이 되어 있는 산업 특성상 일자리 창출 여력이 크다. 그러나, 최근 사용 후 가구의 처리 동향을 살펴보면 재사용 가치가 충분한 사용 후 가구마저도 파쇄되어 고형연료(SRF)로 활용되고 있는 사례가 많으며, 폐기물 처리업체는 지속적으로 감소하면서 폐목재 적체 현상으로 이어지고 있다. 이 같은 문제를 해결하기 위한 방안으로, 순환이용효율성이 높은 사용 후 가구 재제조 비즈니스 모델을 제안하고자 한다. 재제조는 자원 및 에너지 절감 효과가 크고, 고용창출 효과가 높다는 점에서 사용 후 가구에 적용 시 산업경제적 파급효과가 클 것으로 사료된다. 이에 본 연구에서는 해외의 사용 후 가구 재제조 과정을 분석하여 그 특성을 파악하고 이를 바탕으로 경제성 및 환경성 분석을 수행하였다. 경제성 분석 결과, 1인 사업장 기준으로 사용 후 가구 재제조를 통한 연간 예상수익은 약 104백만원, B/C 분석결과는 30으로 높은 사업성을 확보하는 것으로 나타났다. 이는 우리나라 1인 근로자 가구 연평균 소득의 3.11배(연평균 소득은 33백만원)에 달하는 수준이며, 같은 중량의 SRF로 재자원화할 경우의 수익 325천원보다 320배 높은 수준이다. 또한, 환경성 분석결과, 기존의 목재펠릿으로 가공하는 재자원화보다 재제조함으로써 얻을 수 있는 연간 온실가스 저감효과는 연간 2.2 tCO2-eq.이며, 이는 소나무 937그루 또는 신갈나무 622그루가 연간 흡수하는 온실가스의 양과 유사한 수치이다. 이러한 연구결과는 폐기단계에서 경제적 환경적 효과를 고려한 재자원화 방법을 우선 적용하는 것이 중요함을 시사해준다.
