Although a fundamental prerequisite for the successful implementation of any waste management plan is the availability of sufficient and accurate data, there are few available studies regarding the characterization and management of gas distribution company waste (GDCW). This study aimed to characterize the industrial waste generated by the East Azerbaijan Gas Distribution Company (EAGDC) and to present environmental management strategies. The EAGDC serves 57 cities and 821 villages with a total population of more than 2.5 million as well as numerous industrial units. The methodology of this study was based on a checklist of data collected from each zone of the company, site visits (observation), and quantity and quality analysis according to the formal data available from different zones. The results indicate that more than 35 different kinds of industrial solid waste are generated in different industrial installations. The most important types of generated waste include empty barrels (including mercaptans, diesel fuel, deionized waters and oil), faulty gas meters and regulators, a variety of industrial oils, sleeves, filter elements and faulty pipes, valves and fittings. The results indicated that, currently, GDCW is generally handled and disposed of with domestic waste, deposited in companies' installation yards and stores or, sometimes, recycled through non-scientific approaches that can create health risks to the public and the environment, even though most of the GDCW was determined to be recyclable or reusable materials. This study concludes that gas distribution companies must pay more attention to source reduction, recycling and reusing of waste to preserve natural resources, landfill space and the environment.
尽管任何废物管理计划成功实施的基本前提是有足够和准确的数据，但关于燃气分销公司废物（GDCW）的特性和管理，可用的研究很少。本研究旨在对东阿塞拜疆燃气分销公司（EAGDC）产生的工业废物进行特征描述，并提出环境管理策略。EAGDC 为 57 个城市和 821 个村庄提供服务，总人口超过 250 万，还有许多工业单位。本研究的方法基于从公司每个区域收集的数据检查表、现场访问（观察）以及根据不同区域的正式数据进行的数量和质量分析。结果表明，在不同的工业设施中产生了 35 多种不同类型的工业固体废物。最重要的废物类型包括空桶（包括硫醇、柴油、去离子水和油）、故障燃气表和调压器、各种工业油、套管、滤芯和故障管道、阀门和配件。结果表明，目前 GDCW 通常与生活垃圾一起处理和处置，存放在公司的安装场所以及仓库中，或者有时通过非科学的方法进行回收，这可能会对公众和环境造成健康风险，尽管大多数 GDCW 被确定为可回收或可重复使用的材料。本研究得出的结论是，燃气分销公司必须更加注重废物的源头减少、回收和再利用，以保护自然资源、垃圾填埋场空间和环境。
