ABSTRACT
The evolution of consumption for decades has intensified the emission of solid and liquid waste, favoring the increase of negative environmental impacts. Thus, studies of the management and reuse of these residues have great relevance in the current world scenario. It is worth noting that the origin of these waste stems from rural areas to large industries, and their complexity is evaluated by researchers throughout the years. Thus, the biological, chemical, and physical properties of these residues are taken into account for their better use. In this segment, biodigestion, pyrolysis, catalysis, composting and combined treatments involving solid and liquid residues are some examples of methods that have contributed to the sustainable management of these waste, either for the generation of energy or adequate disposal of the materials. In the current scenario, it is important to highlight the positive and negative effects of the coronavirus pandemic on the environment, such as the reduction of the emission of industrial waste and polluting gases, and the increase in the generation of household and hospital waste, respectively. In this context, treatments aimed at the proper disposal of solid and liquid residues contaminated with the virus emerge as a new parameter to be evaluated.
