New materials development from natural resin by-products

Natural Resin

The study compares different formulations based on natural raw materials for plastics production and demonstrates the important role that natural resin derivatives can play in the improvement of biobased and/or biodegradable plastics performance, as an alternative to those derived from petroleum.

The final objective is to provide consumers with biodegradable plastic material of excellent technical qualities for the production of packaging and applications in construction, automotive, electronics or agriculture, in a context of environmental and economic sustainability.

GO PinusResina

Monthly new wounds

The PinusResina initiative aims to identify/establish new value chains for the competitive and safe transformation and recovery of pine resin in high value-added products, with the mission of increasing the competitiveness and sustainability of Pinus pinaster and Pinus pinea forest in Portugal, in particular by enhancing resin constituents for new fine chemistry markets - resin chemical industry as the main economic factor in pine ecosystems; toxicity assessment of derived products; analyze the variability of resin composition, biotransformation and the exploitable...

Study of antioxidant activity of pine resin in Tunisia

Resin flow (Forest center of Sidi Bader - Tabarka)

The exploitation of pine forests in Tunisia which covered up to 50% of the total forest area could contribute and generate additional income sources for forest populations. Until now, the resin extraction knowledge was very limited and outdated. In the present study, the assessment of the biological performance of the resin was the main objective in order to detect the antioxidant activity of three pine species in the Tunisian forest.

Supercritical CO2 extraction technique

Left: resin; center: rosin; right: turpentine oil

After harvesting, the resin takes the form of a homogeneous mixture. Its distillation makes it possible to obtain two products: rosin and turpentine oil. The objective of extraction is to isolate and sample these compounds accurately. In other words, it is a question of having the finest possible selectivity. The second objective is not to alter the molecules and thus take full advantage of its qualities.

STRADIVERNIS: study of an organic source varnish based on colophane of maritime pine and linen oil

Violin, in reference to the famous violin maker Antonio Stradivario

The aim of the project is to develop an industrially producible bio-sourced varnish based on gum rosin and linseed oil, inspired by the ancient know-how of the violin maker Antonio Stradivari (1644-1737). The difficulty is to meet the specifications of an industrial manufacture while achieving high performance of the varnish.
