Participation in Naxos2018:  6th International Conference on Sustainable Solid Waste Management

Symborg is taking part in Naxos 2018, the 6th International Conference on Sustainable Solid Waste Management held on the Greek city from 13 to 16 June. Symborg will report on a recent study carried out by the company that expands its research on the involvement of the microbiota in the process of composting waste generated in the production of olive oil.

The aim of the 6th International Conference NAXOS 2018 is to promote improvements in the field of solid waste management through the use of innovative technologies and effective practices. As at the five international conferences already held, this event is attracting the attention of a growing number of academics, local authorities and many companies and professionals.  The Conference addresses all aspects of waste management in various fields closely related to the use of biotechnology, a main area of expertise for Symborg, in the treatment of sludge and agricultural and livestock wastes. Participants learn about the latest advances in biological treatments and the use of biological waste such as biofuels, composting, etc.

Symborg’s study investigated the microbiota in the wastes generated by the production of olive oil and compared the various phases of their composting process. The biotechnological interest in the study of this process was biodegradation of the waste using indigenous microbiota and specially selected strains. During the study, some microorganisms were inoculated to evaluate their influence on the composting process. The resulting identified microbial populations were: nitrogen fixers, recalcitrant degradators, ion solubilizers (P04, Fe), indoleacetic acid producers, etc. Thus the study concluded that after the composting process, the solid wastes obtained after olive oil production are a complete fertilizer and a biofertilizer with the added value of the discovered microbial populations.


One of the products used during the study to activate the microbial population of the waste compost analysed was Vitasoil. Vitasoil is a soil regenerator based on selected rhizospheric microorganisms that increase the microbial population of soils and agricultural substrates. It is particularly effective when revitalising the usually impoverished soils used for agricultural crops. Vitasoil increases fertility and biological activity in the rhizosphere of the crops, improving its microbial balance and preventing soil degradation. Its composition strengthens rhizospheric biotization by the selective use of beneficial microorganisms that increase the quality of the crops and optimise plant production.
