Morocco is one of the rare countries which decided an early lockdown against the new Coronavirus. During this period, we offer techniques that allow efficient processing of household waste to avoid or minimize to take out the trash. We are presenting different techniques that make it possible to treat waste. Then, we have modeled the spread of this pandemic in Morocco using the SIR model. Finally, we have shown the effects of waste management on the proliferation of Coronavirus. The results show that it is better to sort the waste, install a composter or a domestic digester in buildings and hospitals (more precisely in the room of the contaminated person) to produce the compost or methane (renewable energy), which may finally contribute in limiting the spread of the COVID-19 pandemic.

Introduction In late December 2019, an outbreak of an emerging disease (COVID-19) due to a new coronavirus named SARS-CoV-2 started in Wuhan, China, and quickly spread to a significant number of countries 1,2 . The epidemic was declared a pandemic by the WHO on March 11, 2020 3 . In Morocco, the first case, reported on March 2, 2020, was a 39-year-old individual who had just arrived from the Italian city of Bergamo 4 . Figure 1.
