Resin is a natural product that has multiple applications and is highly demanded in the chemical industry. As a non-timber forest product, exploitation of the abundant pine resin in Tunisian forests (50% of the forest area) can contribute to a bioeconomy and can generate additional income for forest populations.
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.
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.
Assessment of resin tapping in pine forests of Castilla y León considering social and environmental values
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.
The data sheets constitute a small technical manual with the precise information so that traditional blacksmiths and small metallurgical workshops can make the tools used in Europe in the work of resin tapping using the method of bark chipping with stimulation, also known as American method.
Guide to the application of the territorial contract for resin tappers, an innovative institutional support formula for the natural resin sector
The autonomous resin tapper trade is precarious due to factors such as the seasonality of the activity, the fluctuation of resin prices, some resination campaigns are even below the profitability threshold, and the difficulty of accessing complementary sources of income.
To support the sustainability of the resin tapper job, this guide proposes a model of territorial contract tailored to this group of workers, which can be used by public administrations to supplement their income through the remuneration of specific commitments and recognition of the positive externalities generated.
The risk of accident is real for the resin tapper. The objective here is not to protect the worker against the accident but rather to avoid the aggravation of the consequences of an accident by alerting the emergency services as soon as possible. The Lone Worker Device is a function that can be useful for both resin tappers and forest workers.
The traditional method of resin tapping is a very time-consuming activity since it requires the resin tapper to visit each tree every 10 to 15 days during the season. In order to develop more efficient methodologies, the results of the first experiments carried out using the new drilling technique are presented.
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.
The objective is to present the different initiatives that exist at the national level in Spain to characterize resin production and the potential of this resource. These initiatives, framed within the Spanish Forest Statistics defined in the Spanish Forest Law 43/2003, include both production statistics and characterization of the forest resources that either produce or could potentially produce resin.
Describe the key elements constituting the natural resin sector in a historical resinous region, underlining the social, environmental and economic importance of resin harvesting, and its potential as an instrument of local development and environmental conservation.
The ResinApp provides the natural resin sector with a tailored tool that allows the traceability of natural resin from the forest to the factory, endowing the industry of first resin transformation with a practical system for the logistic and administrative management of the supply of natural resin, and to the resin tappers with a tool that allows better working conditions, administrative simplification and greater recognition of their work.
RESINEX Operational Group: Professionalization, knowledge transfer and innovation in the resin sector in Extremadura
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 outreach activities, providing a greater territorial scope.
The Decree-Law nº 181/2015, defines the legal regime for the resin activity and circulation of pine resin in Continental Portugal. The regime requires prior notification to the Portuguese Institute for Nature Conservation and Forestry (ICNF) of resin tapping, resin import and export, resin transportation and storage and resin used by 1st transformation industry. The communication is made online through the Resin Information System (SiResin):
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.
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 relevant to be addressed at present.
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.
