FORESPINT - DEVELOPMENT OF COATINGS WITH BIOCIDAL EXTRACTS FROM AGROFOREST WASTE




DESCRIPTION

The FORESPINT project wants to provide a different and closer market outlet for the residual forest and agricultural biomass of the Valencian Community, incorporating bioproducts with antimicrobial activity extracted from certain residues in coatings for the wood, furniture and construction sectors. Currently, a considerable amount of this residual biomass is not revalued or is burned, and most of what is revalued is destined for energy use.
Therefore, one of the novelties provided by the project is to industrially revalue, with a high value in the market, a waste that, in the vast majority of cases, is totally wasted. In addition, the waste to be used in the project is very abundant in the Valencian Community.

OBJECTIVES

The general objective of the project is to provide our companies and end users with coatings that incorporate bioproducts from extracts of agroforestry residues from the Valencian Community with biocidal activity. These coatings, on the one hand, will possess bactericidal and fungicidal activity. On the other hand, they will use biocidal compounds from plants and, therefore, biodegradable and safe, which will replace products generally of fossil origin, which usually require chemical synthesis to obtain them, as well as contributing to the circular economy, allowing reuse of a abundant waste in the Valencian Community, which tends to accumulate untreated at the place of its generation, which increases the risk of fire, pests, etc. or even eliminated by combustion, which contributes to increasing atmospheric CO2.
The specific objectives are:
- Study the results obtained in the AGROFOREF project and select the agroforestry residues of the Valencian Community that have the best biocidal properties in their extracts, with the perspective of their use in coatings.
- Optimize obtaining extracts with biocidal properties from selected waste for the specific purpose of incorporating them into paints and varnishes.
- Incorporate the extracted bioproducts into the coatings, overcoming incompatibility problems and others that may appear.
- Evaluate the mechanical and physical characteristics of new coatings.
- Analyze the biocidal properties of the new coatings.
- Transmit this knowledge to our companies.

RESULTS OBTAINED

Year 2023: The performance of extractive processes has been successfully increased compared to those taken as a reference. The yields of Pinus halepensis and taray extracts have been improved by decreasing the particle size, so this decrease is a general optimization. And in the case of taray, the yield has also been increased by lowering the extraction temperature and using ethanol as a solvent. - HTC extractions show low yields and their use must be understood in the case of carrying them out on a larger scale, with the aim of taking advantage of the solid part of hydrochar for other purposes, and also valorizing the liquid part of the residual biomass. - Purifications of the extracts were carried out using easily scalable and low-cost techniques, characterizing each one using chromatography and spectroscopy techniques, and identifying the substances present. - The bioproducts were analyzed microbiologically and those that gave the best results were selected for incorporation into different coatings. - It has been observed that when extracts are added to a coating, the biocidal capacity of the extract-coating mixture is lower than that of the extract alone, as is to be expected since it is in a lower concentration and embedded within the coating. - The best coating developed from a microbiological point of view was B1 + Taray OP2 at 14% + HTC-1-Ruta-2 at 1%, which gave good results against bacteria. However, the resistance of the coating is lower against fungi. - Most applications especially modify the final aesthetic appearance of the coating. Regarding the physical and mechanical properties, in the selected coating, they are not too affected by the addition of the bioproduct and maintain favorable results.

Deliverables:   


Year 2022: Following the results obtained in the AGROFOREF project, the biomass waste that presented a strong biocidal capacity was selected, specifically the knots of the P. halepensis species (Aleppo pine), wood of the Tamarix species (taray) and the shell of the species Citrus ssp (orange). In addition, other species have been included, such as rosemary, with the aim of continuing to expand the range of chemical substances with biocidal properties.
Modifications have been made to the solid-liquid extraction process, using the Soxhlet process, in order to increase the yield of obtaining the extract (Figure 1 and Figure 2).
Also, work has been done to obtain new extracts, using the hydrothermal carbonization (HTC) technique.
Of the extracts obtained through the optimizations specified above, their biocidal capacity has been evaluated through microbiological tests. It was observed that the extract that presented the best antimicrobial properties was that of wood remains of the Tamarix species. This bioproduct also achieved greater optimization in its extraction.
The study of the compatibility of extractive bioproducts on coatings extended on the market has also begun. Specifically, it has been added to a paint formulated from water-based acrylic resin, with different percentages of bioproduct obtained from orange peel. The resulting incorporation and application looked good (Figure 3 and Figure 4).
