Description
Mestrado em Engenharia do Ambiente - Tecnologias Ambientais - Instituto Superior de Agronomia Composting is one of the most viable alternatives for effective solid waste management and is an advantageous technology in the treatment, recycling and recovery of biomass. This study aimed to evaluate the evolution of Green Waste Composting in the Composting Plant of Barlavento which belongs to ALGAR S.A., through determination of physical, physico-chemical and chemical parameters in samples of biomass in composting and final composts. Another objective of this study was to assess the phytotoxicity of composts using germination and growth tests with following species: Watercress (Lepidium sativum L.), Lettuce (Lactuca sativa L.) and Tomato (Lycopersicon esculentum L.). Results show some variation for the parameters measured in the samples taken during composting process which can be related to fluctuations in weather conditions, because composting process took place in an outdoor park. Results for germination and growth tests indicate that the final composts have adequate stability and maturation levels.
