Case studies tagged with resin harvesting

Explore options in Pinus pinaster stand management with adapted methods to improve compatibility between resin and timber uses.

The aim is to verify whether the 20 cm wide resin tapping wounds, wider than the traditional 12 cm, can lead to an increase in the annual resin production per tree and if this tapping method is compatible with the traditional wood use in Galicia.

The attractiveness of the resin tapper's profession is a key point for the revival of natural resin extraction to be a success. The aim is to adapt the resin extraction method to reduce the difficulty of the resin tapper's work. In creating the Biogemme© method, Holiste has taken this aspect into account. This involves, in particular, the creation of an appropriate tool to mechanize the harvest.

Sometimes, the profitability of a natural resource use depends more on the business model and the entrepreneurial culture on which its exploitation is based, than on productivity factors or technological development associated with the use itself.

An innovative business success case, linked to the natural resin extraction activity, such as Pinaster Servicios Medioambientales, can serve as a reference for private entrepreneurs and public decision-makers and administrators to develop and support efficient business strategies that integrate the resin activity.

Researchers and forest managers interested in the study of the resin resource have difficulties in locating and accessing experimental data generated in previous projects. 

This circumstance means the loss of precious research and management resources and the experimental data, obtained at the cost of significant technical and economic effort.

SustForest Resin Lab is a platform to share experimental and management data, facilitating both the offer of such data, as well as access to data generated by other agents and the possibility to request its use. 

The association "Gemme la forêt d'Aquitaine" was founded on 7 March 2014. Its aim is to revive resin extraction in the Landes de Gascogne forest. It is with this objective in mind that the members of the association have decided to come together in order to pool knowledge, research and initiatives across the entire value chain: from the forest to consumer expectations through processing.

To explore options for the management of pinaster pine stands that lead to increased resin production and therefore improved profitability, thus reducing dependence on the economic conditions of the market.

Along with the latest advances in the resin sector for improving resin production, such as forest tree breeding, innovative harvesting technology, etc, prescribed fire is also analysed as a tool for increasing resin yield in Pinus pinaster stands. The results of this study are summarized below.

The aim of this work was to enhance the extraction technique of pine needles active molecules to valorize the non used needles.

The RESINEX Operational Group (OG) and its innovation project are presented, the aim of the latter being to boost the resin sector in Extremadura. This OG comprises companies, associations and research centres with close links to the Forest Sector. The promotional institutions included in this OG cover environmental management from different perspectives. This diversification enables products and processes that can be improved within the forestry sector to be identified. The beneficiary associations provide a direct link with the workers in the sector, as well as forming part of the...

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...

The wide potential of resin acids as bioactive agents could be considered as very promoting products for new applications of the natural forms and their derivatives.

The objective of the present investigation was mainly focused on the assessment of the biological performance of the resin. Therefore, the evaluation of the antibacterial activity of the three Tunisian pine species Pinus pinaster, Pinus pinea, and Pinus halepensis were conducted in order to control four pathogenic bacteria species.

In order to ensure the sustainability of the exploitation of pine resin and to guarantee that it is guided by good management practices - promoting the vitality of pine forests and forest protection practices, contributing with relevant annual revenues - it was considered necessary, in Portugal, to define a legal regime, simplifying and concentrating all the rules in a single legal document. This legislation is an essential knowledge tool for authorities and economic agents, focusing on the production, exploitation and dynamics of resin from the forest to the industrial processing unit.

The study advances in the socio-labour reality knowledge of the Spanish workers dedicated to the resin extraction, and in the group perception about aspects related to entrepreneurship and sectorial problems.

To this end, three key aspects are elucidated:

• The definition of the typical resin workers profiles, and the socio-labour situations that characterise each one of them.
• The study of the key factors for the incorporation and the abandonment of the resin activity.
• The sounding of sectorial or professional aspects that the workers consider most

The pine forests on the sandy plains of inner Spain represent a singular habitat and ecosystem in very poor site conditions. In addition to economic revenue from sustainable biological resources, resin tapping provides other ecological and social benefits from these forests. The present study, resulting from the SUDOE project SustForest, analyses the inclusion of these factors in the assessment of resin resources.
