Abstract

In this study, we analyze the current state of domestic food waste (FW) recycling and propose a management plan for greenhouse gas (GHG) emissions. First, the composting potential of the GW demonstrates considerable promise. In particular, the GW (phytoplankton, periphyton, macrophyte, etc.) as a third-generation biomass shows strong performance as a functional additive that mitigates the disadvantages associated with composting FW and improves the quality of the final composted product. Alternatively, the final product (e.g., soil ameliorant) can be used to produce bio-filters that are effective pollutant buffers, with high applicability for green infrastructure. The proposed ecological approaches create new opportunities for FW as a resource for the reduction of GHG emissions, and are expected to contribute to the establishment of effective net-zero carbon systems in the future.

본 연구에서는 국내 음식물쓰레기 (food waste, FW) 분야에 대한 재활용 현황을 분석하고 green house gases (GHG) 배출 관리방안에 대해 고찰하였다. 연구 결과, FW의 자원 활용성을 향상시키고 GHG 배출을 부가적으로 저감시키기 위해서는 적절한 선순환체계가 필요하다는 결론을 얻었다. 효과적인 퇴비화를 위해서 우선 GW의 활용이 고려되었다. 특히 3세대 바이오매스로써의 GW (phytoplankton, periphyton, macrophyte etc.)는 퇴비화 공정에서 FW의 단점을 보완하고 질적 능력을 향상시킬 수 있는 좋은 기능성 첨가제로 판단된다. 또 하나의 접근법은 최종산물 (예: 토양개량제)을 오염물질 완충이 가능한 bio-filter로 가공하여 그린인프라에 적용하는 방안이다. 이러한 생태공학적 접근과 시도는 안정화된 재활용 산물의 기존 활용 이외에도 FW 자원화에 대한 새로운 적용처를 제시할 수 있으므로 향후 효과적인 탄소 넷제로 (Net-Zero) 시스템 구축에 기여할 수 있을 것으로 판단된다.
