A Basic Study on the Estimation of Greenhouse Gas Emissions through the Analysis of the Properties of Household Waste in Northern Gyeongsangbuk-do

In order to achieve the National Greenhouse Gas Reduction Target, the government and Gyeongsangbuk-do waste sector are planning to significantly expand the waste reduction and recycling rate. Household waste in the northern part of Gyeongsangbuk-do burns household waste from 11 northern local governments at “Clear Nuri Park”, a wide-area waste treatment facility, and close properties and surveys of household waste are needed to reduce greenhouse gases generated by incineration and resource recovery facilities. Constellation analysis investigated a total of 1,110.4 kg of household waste over three seasons (spring, summer, and fall), with paper being the most common with 259.5 kg (23.4%), followed by other 256.8 kg (23.1%) > vinyl 241.6 kg (21.8%) > plastic 99 kg (8.9%). Recycling waste accounted for the largest proportion of household waste in the northern part of North Gyeongsang Province with 695.2 kg (63.0%), followed by incineration with 321.5 kg (29.2%), food logistics with 82.5 kg (7.4%), hazardous waste with 2.4 kg (0.2%), and landfill with 1.8kg (0.2%). According to the estimation of greenhouse gas generation from the incineration of household waste in the northern part of Gyeongsangbuk-do in 2022, the total greenhouse gas emission was 75,052.4tCO2eq, and Andong City was the largest with 28,217.6tCO2eq, followed by Yeongju City with 13,462.3tCO2eq and Sangju City with 7,426.1tCO2eq. Based on the amount brought into Clear Nuri Park in 2022, the total reduction of greenhouse gases was 12,012.94tCO2eq, of which Andong City had the largest reduction with 4,637.52tCO2eq reduction, followed by Yeongju City with 1,938.18tCO2eq and Sangju City with 1,133.48tCO2eq. In the case of reduction by constellation, plastics were found to be the most reduced to 11,779.7tCO2eq, followed by rubber leather 152tCO2eq, paper 59.1tCO2eq, and other household wastes 18.6tCO2eq. It is necessary to check the ratio of properties with high greenhouse gases (plastics and rubber leather) through the analysis of household waste properties by city and county.
