Abstract

The aim of this study was to assess the feasibility of a landfill project to reduce greenhouse gas (GHG) from La Chureca Landfill in Managua, Nicaragua ("Project"). The feasibility study involved surveying the status and composition of waste on its way in to the landfill and projecting GHG emissions from the landfill. A projection of the GHG emissions with the IPCC model based on the survey results indicated the period 2006 to 2043 would see mean yearly GHG emissions of 290,147 ton-CO2/year with model certainty not considered, and 217,610 ton-CO2/year with model certainty considered. Thus, the result exceeded the corresponding median and mean values of other CDM projects implemented in Central America, even after model uncertainty was considered together with the conservative estimation of carbon capture efficiency. The similar result was produced even with an analysis of sensitivity to error factors. All the findings of the study are expected to be applicable as basic data for deciding about whether & how to proceed with the Project.

본 연구는 니카라과 마나과 La Chureca 매립장의 온실가스 감축 사업을 하고자 매립장 반입현황조사, 폐기물 성상조사 및 온실가스 배출량 산정을 하였다. 반입량과 성상조사를 바탕으로 한 IPCC 모형을 통한 온실가스 배출량 산정 결과 2006년부터 2043년까지 연평균 290,147 ton-CO2/year였으며, IPCC 모형의 불확도를 고려하여 보수적으로 산정한 배출량은 217,610 ton-CO2/year로 나타났다. La Chureca 매립장에서 온실가스 포집 가능량을 모형 불확도를 고려하고 포집 효율을 보수적으로 산정했음에도 CDM에 등록된 다른 중미 사례의 중간값과 평균값을 상회했으며 오차 요인에 대한 민감도 분석에도 결과가 크게 다르지 않았다. 본 연구는 La Chureca 매립장 온실가스 감축 사업의 타당성을 평가하고 이행 방안을 도출하기 위한 온실가스 배출량에 대한 기초자료로 활용이 가능할 것으로 판단된다.
