由于许多环境和社会因素，预计不同社会经济群体的固体废物产生率会有所不同。本文报告的评估固体废物产生的基础上不同的社会经济参数，如教育，职业，家庭收入，家庭成员人数等进行了问卷调查，在研究区域，以确定不同的社会经济群体，可能会影响固体废物的产生率和组成。该市产生的平均废物为0.41公斤/人/天，其中最大的废物是由中下层社会经济群体（LMSEG）产生的，平均废物产生量为0.46公斤/人/天。废物特征表明，除了灰渣和塑料外，不同社会经济群体的废物组成没有太大差异。灰烬残留物被发现增加，因为我们向下移动的社会经济群体最大（31%）在较低的社会经济群体（LSEG）。研究区域是一个以煤炭为基础的城市，因此在较低的社会经济群体中使用煤和木材作为烹饪燃料是灰分含量高的原因。高社会经济群体（HSEG）的塑料废物最多（15%），LSEG最少（1%）。食物浪费是几乎每个社会经济群体产生的废物的主要组成部分，在HSEG中最高（38%），在LSEG中最低（28%）。这项研究提供了新的见解的作用，各种社会经济参数对家庭废物的产生。(C)2016爱思唯尔有限公司版权所有。
The solid waste generation rate was expected to vary in different socioeconomic groups due to many environmental and social factors. This paper reports the assessment of solid waste generation based on different socioeconomic parameters like education, occupation, income of the family, number of family members etc. A questionnaire survey was conducted in the study area to identify the different socioeconomic groups that may affect the solid waste generation rate and composition. The average waste generated in the municipality is 0.41 kg/capita/day in which the maximum waste was found to be generated by lower middle socioeconomic group (LMSEG) with average waste generation of 0.46 kg/capita/ day. Waste characterization indicated that there was no much difference in the composition of wastes among different socioeconomic groups except ash residue and plastic. Ash residue is found to increase as we move lower down the socioeconomic groups with maximum (31%) in lower socioeconomic group (LSEG). The study area is a coal based city hence application of coal and wood as fuel for cooking in the lower socioeconomic group is the reason for high amount of ash content. Plastic waste is maximum (15%) in higher socioeconomic group (HSEG) and minimum (1%) in LSEG. Food waste is a major component of generated waste in almost every socioeconomic group with maximum (38%) in case of HSEG and minimum (28%) in LSEG. This study provides new insights on the role of various socioeconomic parameters on generation of household wastes. (C) 2016 Elsevier Ltd. All rights reserved.
