On November 14, 2018, a new meeting of the VALORCOMP consortium was held to present the progress made within the framework of the project. The partners were kindly invited to attend the meeting at Resíduos do Nordeste facilities in Mirandela (Portugal). As usual, representatives of all partners attended the meeting: Polytechnic Institute of Bragança (IPB, Project manager), CIDAUT Foundation, University of Valladolid (UVa), Resíduos do Nordeste (RN) and Nertatec.

The main objective of the meeting was to share the progress of the work in each of the aspects of use of the compost consider in VALORCOMP project. Thus, within the thermochemical use, the participants of CIDAUT presented their results highlighting the proper compost compaction and the start of the second action of this activity, the pilot scale tests. The IPB presented its results in the context of the use of compost as a material, highlighting the applicability of this material as a catalyst in oxidation processes for wastewater treatment and the possibility of using it as a raw material to be incorporated in ceramics instead of in cements.

For its part, the UVA has obtained a product that meets specifications as a fertilizer in the study of possible agronomic use. The process includes an extraction of organic matter with potassium hydroxide. Germination trials have been conducted using the fertilizer with positive results.

In the course of the meeting, the problem of bio-stabilized residue (composted waste from non-selective collection) was discussed at length. It was focused on the difficulty of using this waste derived from the future regulation of waste reduction to landfill, as well as increasing the percentage of waste prepared for recycling into the treatment plants. Selective collection was analyzed as a solution for obtaining a compost (and not bio-stabilized residue) from the organic fraction, questioning the feasibility of executing it, the cost it would entail for the citizen and if this could guarantee the quality of the compost.

In communication and dissemination activity, it was agreed to undertake a series of actions to strengthen the content of the project’s website and create a private area to encourage communication between project partners. On the other hand, the brochure design was approved to disseminate the project.

Finally, all the partners were summoned to a next meeting in March 2019 in Valladolid.

This project is co-financed by the programme of cooperation INTERREG V-A Spain-Portugal (POCTEP) 2014-2020 and will run until September 2019. Project VALORCOMP aims to contribute cooperatively to solve cross-border problems in the valorisation of waste generated in the treatment of the organic fraction of municipal solid waste.
