ECORKWASTE: Preliminary studies demonstrate the potential of the projects

This September, the fourth follow-up meeting of the Ecorkwaste project was held at the headquarters of the INNOVI Catalan Wine Cluster. All the partners of the project participated in the meeting: Fundació CTM Center Tecnològic, Institut Català del Suro, Grupo TYPSA, Universitat Politècnica de Catalunya and INNOVI.



The meeting focused on assessing the first preliminary results of the start-up of both the gasification plant and the wetland built at the Codorníu facilities in Sant Sadurní d'Anoia.

The gasification plant is operating as planned and work is being done on it at this time efficiency tests with cork particles between 3-7 mm with low beds and high temperatures ranging from 200ºC to 800ºC. In these conditions the plant reaches its optimal operation.

On the other hand, the constructed wetland also operates properly with a daily flow of 4500 l/d. During the month of September, several samples were taken and technical visits were carried out in order to obtain data during the harvest period, a key time of the year in the wine sector and its production centers. The quality of the water being treated is good, although the project partners note that one of the goals of the constructed wetland must be to further refine it to increase its quality.
Once the operability of the two pilot plants has been consolidated, the environmental gain of the two valorization strategies, both material and energy, has been determined using the life cycle analysis (LCA) methodology.

The results obtained so far, despite their preliminary nature, demonstrate the potential of the technologies developed.

It highlights the potential for energy generation through a renewable source exceeds the environmental cost of the gasification process.

And in the case of the treatment of waste water with constructed wetlands, the use of photovoltaic panels helps to
contain the impact of the process.

In both systems, efforts in the coming months will focus on evaluating the benefits and impacts related to toxicity, critical aspects to establish their environmental benefits.
