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.

COVID-19和家庭废物产生:趋势分析

除了健康方面和高死亡人数之外,COVID-19大流行自2020年3月获得官方认可以来,还造成了可能的社会和经济问题。这也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水平提高。

本文报道了一项国际研究,该研究涉及自COVID-19大流行以来消费量的增加以及随后产生的废物量的变化。结果表明,有45–48%的受访者发现包装食品,新鲜食品和外卖食品的消费量增加。封锁期间废物产生增加的主要原因之一是人们在家里花费了更多的时间。此外,餐厨垃圾和塑料包装分别增长了43%和53%。通过对大流行之前和期间产生的生活垃圾数量的比较得出的结论表明,某些特定类型的城市垃圾明显增加,给垃圾管理系统带来了额外压力。这是COVID-19大流行的非预期影响之一。这项研究的结果为城市行政管理部门和市政公用事业部门在紧急情况下的消费模式提供了有用的见解。反过来,这可以支持采取更多的系统性和战略性措施,以减少大流行期间家庭废物的增加。
