Apart from the health aspects and the high death toll, the COVID-19 pandemic has, since its official recognition in March 2020 caused may social and economic problems. It has also led to many environmental ones. For instance, the lockdowns have led to higher levels of consumption of packaged products, and of take-away food. This paper reports on an international study on the increased consumption and subsequent changes in the amounts of waste produced since the COVID-19 pandemic. The results show that 45-48% of the respondents observed an increased consumption of packed food, fresh food, and food delivery. One of the main reasons for the increased waste generation during the lockdown was the fact that people have spent more time at home. In addition, increases of 43% and 53% in food waste and plastic packaging. Drawing from comparisons on the amount of domestic waste produced before and during the pandemic, the findings suggest that some specific types of municipal waste have visibly increased, putting additional pressure on waste management systems. This characterises one of non-intended effects of the COVID-19 pandemic. The results from this study provide useful insights to city administrations and municipal utilities on consumption patterns during emergency situations. This, in turn, may support more systemic and strategic measures to be taken, so as to curtail the increase of household waste during pandemic situations.
除了健康方面和高死亡率之外,自 2020 年 3 月正式确认以来,COVID-19 大流行还造成了许多社会和经济问题。它还导致了许多环境问题。例如,封锁导致包装产品和外卖食品的消费增加。本文报告了一项关于 COVID-19 大流行以来消费增加以及随之产生的废物量变化的国际研究。结果表明,45-48%的受访者观察到包装食品、新鲜食品和送餐的消费增加。在封锁期间产生的废物增加的主要原因之一是人们在家的时间增加。此外,食物垃圾和塑料包装的增加分别为 43%和 53%。通过对大流行前后产生的城市垃圾量进行比较,研究结果表明,某些特定类型的城市垃圾明显增加,给废物管理系统带来了额外的压力。这是 COVID-19 大流行的非预期影响之一。本研究的结果为城市管理部门和市政公用事业提供了有关紧急情况下消费模式的有用见解。这反过来又可以支持采取更系统和战略性的措施,以遏制大流行期间家庭垃圾的增加。
