As the building sector is one of the leading responsible for energy consumption and CO2 emissions, criteria of sustainability, availability, and recyclability should be considered for developing materials even in the envelopes. Façade, as the first element against the undesirable external impact, may contribute to building sustainability by reducing the amount of energy consumption and providing indoor environment quality for the inhabitants. The envelope excluding its aesthetic function should fulfill certain requirements such as strength, flexibility, ductility, lightness, thermal and acoustical insulation, durability, and sustainability. Fiber/Textile cement sheets as an interesting architectural material attract great interest during the last decade, especially those reinforced with more sustainable fibers like vegetables or textile wastes. In this sense, this paper presents a novel model to evaluate the sustainability index of façade cladding panel, especially the fiber/textile cement board. To this end, a new model for assessing objectively the façade cladding sustainability was designed and developed based on MIVES according to the value function concept and seminars of experts.

Nowadays, the needs and requirements to avoid infections during surgical operations, require to be
more imaginative than ever. The one-use textiles substrates that are used in hospitals can be, also, a
way to transport the antibacterial effect around the own building. This is the main objective of this
work; to use clothes and textiles surfaces as antibacterial systems using natural components.
Microencapsulation has shown in several occasions the effectivity to protect and vehiculize active
principles that can be used for medical treatments. In this case, essential oils have been used as
antimicrobial agent, that when combined with shell polymers based on Chitosan of different molecular
weight distribution and Arabic gum, allows them to act against Gram (+) and Gram (-) bacteria.
Chitosan has been shown to be a biopolymer with a wide range of applications and is highly
dependent on its molecular weight. The study of the efficiency of the final systems obtained present
high valuable possibilities, due to its character similar to hydrogels. The influence of the molecular
weight of biopolymers used, in a layer by layer approach (LbL), has been demonstrated and shows a
very promising way to state a clear control on the delivery mechanisms. The essential oil used has a
very volatile character formed by more than 40 components and with the help of FT-IR and TGA it has
been possible to corroborate that all its components were encapsulated. The impregnation of the
different samples to the tissue was successful and allowed the antibacterial study to be carried out,
which was carried out in duplicate on each sample and demonstrated that they have bacterial activity.

One of the great advantages of electrospun fibers is the large tridimensional area produced, capable of storing any type of material. The aim of our investigation is to study the electrospinning technique to produce polymer membranes for drug delivery applications, given their large surface area and ability to transport a bioactive compound. A mathematical modeling of the delivery system kinetics was also studied to find the mechanism that controls the releasing process. Results showed that electrospinning could provide regular and smooth membranes suitable for drug delivery processes. The choice of a proper solvent for this process was an important parameter analyzed, because it determined whether fibers were capable of forming, as well as influencing fiber porosity. The mathematical modeling also proved that thicker PLLA membranes exhibited a Fickian diffusion behavior during the drug transport, presenting better control in drug delivery processes

The textile dyeing produces a large volume of wastewater with high salinity and deep colouration. Residual dyes are generally not removed in conventional wastewater treatments and therefore specific treatments are required to remove colour. Sometimes, textile mills are not able to accomplish water discharge regulations as salts cannot be removed in the common wastewater treatments. To face both problems, salinity and colour of effluents, a new system has been designed based on a coupled electrochemical and UV process (EC-UV). It is a fast and simple treatment that enables the effluents colour removal. In addition, the wastewater salinity can also be reduced through the reuse of the treated effluents in new productive processes. The treatment is particularly efficient in the reactive dyeing process, although it can also be used for direct effluents. The implementation of this new system in the textile industry achieves significant benefits. The reuse of effluents containing high amount of salts implies lower consumption of water and salt in the dyeing process, and the removal of colour improves the yield of wastewater treatment plants with less consumption of chemicals. Finally, the reduction of wastewater salinity is also an additional economic and environmental benefit of the treatment, which results in lower wastewater taxes and improvement of the aquatic ecosystems
