The novel coronavirus (2019-nCov) has had significant impacts on almost every aspect of daily life. From 'stay-at-home' orders to the progressive lifting of restrictions, the COVID-19 pandemic has had unprecedented effects on consumer behaviours and waste disposal habits. The purpose of this short communication is to examine time series waste collection and disposal data in a mid-sized Canadian city to understand how behavioural changes have affected municipal waste management. The results suggest that private waste disposal increased during the pandemic. This may be due to people doing home renovations in order to accommodate working from home. Furthermore, it appears that changes in consumer habits destabilized the consistency of waste disposal tonnage when compared to the same time period in 2019. When considering curbside residential waste collection, there was also an increase in tonnage. This may be the result of more waste being generated at home due to changes in eating and cooking habits, and cleaning routine. Finally, the ratio of residential waste collection to total disposal is examined. More residential waste is being generated, which may have environmental and operational effects, especially related to collection and transportation. The results from this study are important from an operational perspective, and will help planners and policy makers to better prepare for changes in the waste stream due to pandemics or other emergencies.
新型冠状病毒(2019-nCov)对日常生活的几乎各个方面都产生了重大影响。从“居家令”到逐步放宽限制,COVID-19 大流行对消费者行为和废物处理习惯产生了前所未有的影响。本简讯的目的是研究加拿大一个中等城市的时间序列废物收集和处理数据,以了解行为变化如何影响城市废物管理。结果表明,大流行期间私人废物处理量增加。这可能是因为人们为了适应在家工作而进行家庭装修。此外,与 2019 年同期相比,消费者习惯的变化似乎使废物处理吨位的一致性变得不稳定。当考虑到路边住宅废物收集时,吨位也有所增加。这可能是由于饮食习惯和烹饪习惯以及清洁习惯的改变,导致在家中产生的废物增多。最后,考察了住宅废物收集与总处置的比例。产生的住宅废物更多,这可能对收集和运输等方面产生环境和运营影响。本研究的结果从运营角度来看非常重要,将帮助规划人员和政策制定者更好地为因大流行或其他紧急情况而导致的废物流变化做好准备。
