Revalorization of coastal algae wastes in textile nonwoven industry with applications in building noise isolation
The development of this GP (based on the methodology and results of SEAMATTER project) is detailed as follows:
- First stage to study the current situation of the management of algae and seaweed deposition wastes from the coast (municipalities and companies in charge of the management of the coastal wastes).
- Optimization of the method of management of the seaweed deposition wastes. Collection from Valencian coasts (located in El Campello, Alicante).
- Definition, selection and characterization of the properties of coastal vegetal wastes to obtain nonwovens.
- Wet-laid application to obtain nonwovens that act as reinforcement structures in composites.
- Processing of composites through different technologies with the obtained nonwoven.
Infrastructure (machinery, vehicles, planning, etc.) required for collecting, treating and revalorizing of algae waste through a nonwoven manufacturing process.
In the GP, textile machinery for nonwoven production is wet-laid. Other processes and machinery are referred to production of composite
Evidence of success
SEAMATTER demonstrated that non-woven textile structures made from coastal vegetal wastes can be used as composites reinforcement in noise isolation acoustic panels and other composite structures. Wet-laid technology has been selected as the most optimum technology to transform the algae wastes in nonwovens to be used as reinforced structure.
Potential for learning or transfer
Key success factors for transferring are:
• Possibility of give value not only to the Posidonia Oceanica wastes but also other types of algae-based wastes.
• Acoustic isolation panels to be applied in the building sector can be obtained.
• The nonwovens developed are easily applicable also as reinforcement for obtaining composite materials.
• Public and private entities can be involved, in order to look for benefits that directly impact on the society.
• Specialization of technicians who develop products for new markets/applications. Increasing of knowledge of technicians.
• A full strategy to implement the GP is required, including some funds for implementation, machinery and auxiliary installation devices.
• Technologies to develop new products are well-known.
• Specialization and re-conversion of traditional textile companies that are currently producing nonwovens or isolation products.
