Compostagem de lodo biológico e resíduos orgânicos: uma análise bibliométrica usando a base de dados Scopus

Abstract

In recent decades, the management of organic solid waste has become a significant concern for the environment and public health, as the disposal of this waste in landfills, in addition to reducing its useful life ends up generating greenhouse gases. Another environmental problem that has expanded discussions is the impact of the generation of sewage sludge from the treatment of effluents. Agriculture has used Sewage sludge as a source of nitrogen (N), phosphorus (P), and organic matter for the soil. However, some factors such as heavy metals, persistent organic pollutants, and pathogens can affect soil microbiota. Consequently, hinder the transformations mediated by microorganisms in biogeochemical cycles. Therefore, this study aimed to carry out a bibliometric analysis and a systematic literature review on global trends in the lines of research that unite composting and sewage sludge management. Using the Scopus database were selected 236 scientific articles, published between 1972 and April 2021. The volume of annual publications on this subject showed a growing trend, especially from the 2014 years, indicating that the interest in the theme continues to grow. Finally, the bibliometric analysis revealed the main research trends and offered potential indicators for a deeper examination of topics related to the topic.
