Progress and Results

  • Study of the current situation of the management of algae and seaweed deposition wastes from the coast:

In this study, it has been reviewed the procedures for collection, transportation and cleaning procedures. For these tasks has been necessary to contact with the different municipalities and companies who are in charge in the management of the wastes algae.

It is important to mention that nowadays the management of this kind of wastes have high economic costs: as an example, managing 1Tn of algae wastes cost 100€. Regarding the environmental problems, these kind os wastes are accumulated in landfills. 

  • Optimization of the method of management of the algae/plants and seaweed deposition wastes from the coast

In order to define the best solution for collecting the marine wastes from the coast and to suggest techniques for transport and storage the algae wastes, some entities which work on the management and collection of Posidonia has been contacted. Once the process will be well know, a pilot experience will be proposed where the most optimum technological solution for the management of the algae wastes will be fixed up by means of technological improvements that will allow the correct disposal of the generated by-products when collecting the algae and other marine wastes from the beach.

  • Definition, selection and characterization of the properties of algae wastes to obtain nonwovens

The main activities carried out have been the definition of the marine algae wastes collected from the beach and how have to be the presentation of the algae to be used as a raw material for wet-laid process. As well has been defined the mechanical process to get several length of the algae and the characterization of the different algae wastes length has been carried out. Finally the different algae wastes length has been used as a raw material in the development of wet laid nonwovens to study the behaviour during the processing of the different lengths. This material has been characterized in terms of mechanical.

  • Wet-laid application to obtain nonwovens that act as reinforcement structures in composites

In this action has been carried out the collection, management and storage of the algae wastes and the cleaning process and preparation of the raw material to develop wet laid nonwovens in order to optimize the wet laid process parameters. 

From this information and once the non-woven has been optimized  different samples have been obtained by wet-laid technology and will be characterized and used as a reinforcement of the composite material studied.

  • Processing of composites

We worked on the performance of composites reinforced by non-woven materials derived from algae/plants and seaweed wastes. Compression moulding has been considered aas the processing technique to be used to perform this activity. The action started with the selection of the polymeric matrix (PLA) to be used for the preparation of the desired composite materials, moreover mechanical and physical properties of the obtained composites are going to be tested in order to guarantee further applications of them in the acoustic isolation field.


  • Monitoring of the impact of the project actions

With the environmental and economic Information obtained from above actions partners worked in:

    • Study of the current procedures of collection, logistic and disposal of the natural wastes materials.
    • Economical study of the collection, logistic and disposal of the natural wastes materials.
    • Economical study of the raw materials.
    • Economical study of the wet-laid nonwoven production
    • Economical study of the cleaning, drying and cutting processes of the algae wastes.
    • Study of the impact of the dissemination action
