This study aims to investigate the emanating challenges in urban and healthcare waste management in Isfahan, after the new Coronavirus outbreak. Production of 'dry wastes' in Isfahan, with a population of more than 1.9 million, has increased during the pandemic. Personal protective equipments (PPEs) including face masks, single-use gloves and face shields are an emerging group of materials in Isfahan's waste stream. On average, Isfahanian residents have daily discarded over 1.49 and 2.98 million pieces of facemasks and plastic gloves, respectively, after the new Coronavirus pandemic. Overall production of hospital wastes in Isfahan slightly decreased during the pandemic. COVID-19 related wastes in hospitals are mainly treated by wet autoclave method, then collected and transferred to the Sejzy site to be landfilled. Waste separation, recycling and composting programs have been banned due to the COVID-19 pandemic, and all collected MSW are directly disposed of at Sejzy disposal site. Composting as the main disposal method for 60%-70% of the MSW in Isfahan has been terminated; therefore landfilling of urban wastes has dramatically escalated by 3.6 times. Appropriate urban waste management protocols must be provided to restart safe separation, recycling and composting programs to reduce pressure on land for disposal, while practicing safe waste management measures to minimize the possibility of the spread of the viral disease.
这项研究旨在调查新型冠状病毒爆发后伊朗伊斯法罕市在城市和医疗废物管理方面面临的挑战。在拥有 190 多万人口的伊斯法罕,“干废物”的产量在疫情期间有所增加。个人防护设备(PPE)包括口罩、一次性手套和面罩,是伊斯法罕废物中的一个新兴材料群体。自新型冠状病毒疫情爆发以来,伊斯法罕居民平均每天丢弃超过 149 万和 298 万片口罩和塑料手套。在疫情期间,伊斯法罕的医院废物总产量略有下降。医院中与 COVID-19 相关的废物主要通过湿式高压灭菌器法进行处理,然后收集并转移到 Sejzy 场地进行填埋。由于 COVID-19 疫情,废物分离、回收和堆肥计划已被禁止,所有收集的 MSW 都直接在 Sejzy 处置场进行处置。作为伊斯法罕 60%-70%的 MSW 的主要处理方法,堆肥已经停止;因此,城市废物的填埋量急剧增加了 3.6 倍。必须提供适当的城市废物管理方案,以重新启动安全的分离、回收和堆肥计划,减轻处置土地的压力,同时采取安全的废物管理措施,最大程度地减少病毒疾病传播的可能性。
