Composting of kitchen waste and pet feces: quality and effect on vegetable germination and growth
Keywords:Capsicum baccatum, compost, organic waste, Raphanus sativus
The rates of urban growth and urbanization indicate a projected increase in waste generation. In developing countries, the organic fraction constitutes approximately half of the total waste, leading to the production of leachate, toxic gases, and the emergence of vectors. Composting emerges as a straightforward and cost-effective solution for organic waste recovery. This study focused on evaluating the quality of compost derived from organic waste (CRO) and pet feces (CM). The research aimed to investigate the impact of these composts on the germination and growth of selected vegetables. The primary quality parameters were assessed, and different mixtures of CRO and CM were implemented as experimental treatments. The majority of the fertilizers examined complied with the quality standards. However, the germination percentage of CRO (18%) and CM (10%) fell below the required threshold (80%), and CM surpassed the recommended maximum level of total coliforms (1100 NMP/g compared to the recommended 1000 NMP/g). Notably, a higher germination percentage (84%) was observed for both CRO and CM at a 25% compost addition. In terms of growth trials, the control group exhibited the tallest plants (13.88 cm), followed by the 10% CRO treatment (13.22 cm) and the 25% CM treatment (11.50 cm). The findings underscore the potential of urban organic waste, including pet waste, for composting and its positive impact on plant growth.
