The rapid growth of urban populations has led to a dramatic increase in urban waste generation with environmental and public health problems associated with water contamination, emission of toxic and noxious fumes, soil contamination and introduction of disease vector populations.
The aim of the present study was to assess solid waste disposal practices and challenges of solid waste management in Woldia town, northeastern Ethiopia.
A descriptive research design was employed, using a survey method and naturalistic observational methods. A total of 236 households were surveyed, including waste collectors and cleaners, waste pickers, and 20 students and ten teachers from Woldia secondary and preparatory schools. A purposive sampling technique (made up of municipal officers, scavengers (waste pickers), waste collectors and cleaners and a simple random sampling technique (of teachers, students and of the study area) was employed, then proportional allocation was made for each randomly selected based on population size to determine the sample. Finally, survey questionnaire, interview, focus group discussion and observation were used as data collecting tools. Bivariate and multivariate analyses were also employed.
The current study revealed that educational status (AOR = 10.92, 95% CI = (3.12-38.27)), occupational status (AOR = 8.08, 95% CI = (2.08-31.31)), monthly income (AOR = 5.72, 95% CI = (1.55-21.13)), and age (AOR = 2.53, 95% CI = (1.04-6.19)) were found to be the major factors associated with solid waste management practices. Additionally, shortage of storage materials, lack of alternative waste disposal options, household attitudes, and lack of awareness were the major challenges for low performance of solid waste management practices of the local government and households. The focus group individuals and interviewed participants indicated that solid waste management practices were poor.
The present study revealed that solid waste management practices in Woldia town remain inadequate. Therefore, efforts by the municipality and other stakeholders are needed to mitigate the problem of waste management and disposal practices.

城市人口的快速增长导致城市垃圾产生量急剧增加，带来了与水污染、有毒有害气体排放、土壤污染以及病媒种群引入相关的环境和公共卫生问题。
本研究旨在评估埃塞俄比亚东北部沃尔迪亚镇的固体废物处置做法及固体废物管理面临的挑战。
采用描述性研究设计，运用调查法和自然观察法。共对236户家庭进行了调查，包括垃圾收集者和清洁工、拾荒者，以及来自沃尔迪亚中学和预科学校的20名学生和10名教师。采用了立意抽样技术（由市政官员、拾荒者（垃圾捡拾者）、垃圾收集者和清洁工组成）和简单随机抽样技术（针对教师、学生以及研究区域），然后根据人口规模对每个随机选取的对象进行比例分配以确定样本。最后，使用调查问卷、访谈、焦点小组讨论和观察作为数据收集工具。还采用了双变量和多变量分析。
当前研究表明，教育程度（调整后比值比[AOR]=10.92，95%置信区间[CI]=(3.12 - 38.27)）、职业状况（AOR = 8.08，95% CI = (2.08 - 31.31)）、月收入（AOR = 5.72，95% CI = (1.55 - 21.13)）和年龄（AOR = 2.53，95% CI = (1.04 - 6.19)）是与固体废物管理做法相关的主要因素。此外，储存材料短缺、缺乏替代废物处置选项、家庭态度以及缺乏意识是地方政府和家庭固体废物管理做法表现不佳的主要挑战。焦点小组人员和受访参与者表示固体废物管理做法很差。
本研究表明沃尔迪亚镇的固体废物管理做法仍然不足。因此，市政当局和其他利益相关者需要努力缓解废物管理和处置做法的问题。
