Advantages and disadvantages of vermicomposting toilets

Decentralized human excreta sanitation systems, which include latrines or composting toilets for example, are among the sustainable methods of dealing with this biological waste. One possible way of dealing with human excrement is the vermicomposting method. This work deals with decentralized caused excreta sanitation using a vermicomposting toilet. The aim of the work was to evaluate the applicability of the vermicomposting method for the sanitation of human excrement and to compare this approach with more widespread methods of so-called dry sanitation, such as a composting toilet. The principles of both methods, the necessary conditions for the successful course of the process and the quality of the resulting sanitation products were described. Attention was focused not only on the presence of pathogenic organisms and the effectiveness of individual systems in their removal, but also on other possible pollutants from the group of personal care products or, for example, microplastics. Their potential effect on earthworm viability was also discussed. Other toilet paper can also be an important source of unwanted contamination. Part of the work was cooperation in the realization of an experimental vermicomposting toilet in the Dvůr Perlová voda complex in Kostelec nad Ohří. I found that...
