BACKGROUND
The production of solid waste continues to increase as the population and standard of living increases. In addition, changes in living conditions can induce significant variation in the quantitative and qualitative characteristics of waste.
OBJECTIVES
The aim of the present study was to examine the impact of the lockdown period on the generation of solid waste produced in the city of Marrakech.
METHODS
The tonnage of household waste, construction and demolition waste and green waste was collected from the landfill and an analysis was made during the lockdown period in 2020 in comparison with the same period in 2019.
RESULTS
The analysis of solid waste tonnage in 2019 and 2020 showed that the lockdown had a significant impact on the various wastes; with a 27.61% decrease for household waste, 6.27% decrease in the case of green waste, and 57.40% decrease for construction and demolition waste.
DISCUSSION
The degree to which the tonnage of household waste decreased depended on the standard of living in each district which was defined by housing type. The tonnage of construction and demolition waste was influenced by the halt in construction activity in the city.
CONCLUSIONS
The results of the present study showed that the tonnage of household waste and demolition and construction waste decreased during the lockdown period.

背景
随着人口增长和生活水平提高，固体废物的产量持续增加。此外，生活条件的变化会导致废物的数量和质量特征出现显著差异。
目的
本研究旨在考察封锁期对马拉喀什市产生的固体废物的影响。
方法
从垃圾填埋场收集了生活垃圾、建筑与拆除废物以及绿色废物的吨数，并将2020年封锁期的数据与2019年同期数据进行对比分析。
结果
2019年和2020年固体废物吨数分析表明，封锁对各类废物产生了重大影响；生活垃圾减少了27.61%，绿色废物减少了6.27%，建筑与拆除废物减少了57.40%。
讨论
生活垃圾吨数下降的程度取决于每个区的生活水平，而生活水平由住房类型界定。建筑与拆除废物的吨数受到该市建筑活动停止的影响。
结论
本研究结果表明，封锁期间生活垃圾以及拆除和建筑废物的吨数有所下降。
