Technical standardization of resin tapped pine wood for structural use

(General description of the picture?)

The standardisation study facilitates the inclusion of wood from resin tapped pines in the Spanish standard UNE 56544 (Visual classification of sawn wood for structural use. Coniferous wood), in order to favour its use and marketing as structural wood.

Simultaneously, the study compares the physical-mechanical properties of resinated Pinus pinaster wood against non-resin wood under the same normative parameters (UNE 56544), so that the technical buyer can evaluate which product is the most suitable for the intended application.More


Green Roof and Water Management in Philippines Government Office Building

Quezon City, Philippines

Rapid urbanisation in the Philippines has given rise to many challenges as increasing infrastructure developments contribute to reduced open spaces and increased energy consumption.

Both the public and private construction sectors are responding by reshaping the cityscape and designing building structures that are as environmentally responsive as they are beautiful and compact. Now, buildings should not only be sturdy and spacious, they should also be efficient in energy consumption and adaptive to the changing environment.

LafargeHolcim Philippines (LafargeHolcim) has...More




Lone Worker Device

An example of Lone Worker Device

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.More



Effect of Short and Long Term Irrigation with Treated Wastewater on Chemical Composition and Herbicidal Activity of Eucalyptus camaldulensis Dehn. Essential Oils

General view of the plot irrigated by treated wastewater since 2005 in the treatment plant El-Hamma and cultivated by Eucalyptus camaldulensis aged around ten years

The aim of this work was  to evaluate the effect of treated wastewater short and long-term irrigation on essential oil composition from E. camaldulensis Dehn in order to detect allelopathic impacts on seed germination and seedling growth of Amaranthus hybridus L, Chenopodium album L, Echinochloa crus-galli (L) Beauv and Lolium perenne L as important weeds on many crops.More



ResinApp: A Web/Android App for logistics and natural resin traceability

Natural resin barrel loading

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.More




Forest management adaptation to the production of equally worth non-wood forest products – a practical opinion

In the new context of multifuncionality, the development of management plans integrating both  the wood  and non-wood forest products (i.e. mushrooms and truffles) for a particular area, aiming to increase the total market value becomes a challenge. In the process of management plan formulation, additionally to the scientific knowledge, also the practical experience of collectors should be taken into consideration.More


An example of good practice in the development of the truffle sector

Truffle hunting in Istria began in the mid 20th century when the first written records were recorded about it. Initially, the local population started collecting truffles as it was actually a great addition to their home budget. At this time, the final destination of the truffles were mainly the foreign markets. More recently, the truffle hunters realized that the value can be increased if the product was placed on the domestic market. Thus, in the 1990s, truffle promotion was promoted as a valued product and they quickly realized that diversification of the offer was needed and that...More



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.More



Valorisation of Ziziphus jujuba fruits

Ziziphus jujuba tree (experimental station-Rouhia)

Ziziphus jujuba, known as Chinese jujube, is a highly valued plant native to China. Three species are known in Tunisia: Ziziphus lotus, Ziziphus spina-christi and Ziziphus jujuba. The Ziziphus jujuba also known as “anneb” is the most popular specie. This tree (Figure 1), with 10 cm of length and 50 cm of diameter, offer a delicious read fruit (jujube) that was consumed fresh, dried and processed (jams, loaf, cakes, etc.). The aim of this study was to attempt, for the first time, the chemical compositions of Z. jujuba fruits...More


Conservation, multiplication and utilization of Lavandula stoechas L.

Lavender plant

The Lavandula is an important species due to medicinal and aromatic properties. The local species population is suffering from Anthropozoic pressure improved by cutting and animal scuttling which made it essential to preserve the species population. Our work aims to test some ways of  specie propagation.More


Reduction of the difficulty of the resin tapper's work with the Biogemme© method.

Gemmage mécanisé

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.More



What are the pros and cons of bred and commercial varieties versus local ecotypes?

Survey of wild populations of Salvia lavandulifolia in Catalonia

With the aim of knowing the quality and geographical distribution of some aromatic and medicinal species used at industrial level of the Spanish autochthonous flora, for some years projects were carried out for prospecting wild populations of Rosmarinus officinalis, Thymus vulgaris, Salvia lavandulifolia and Lavandula latifolia among others.

The purpose of these projects was to find quality plant material of these species with which to start breeding work in order to obtain commercial varieties adapted to our soil and climate conditions and make...More


Three processes for green and eco- friendly extraction of natural substances from three Eucalyptus species

Eucalyptus Intertexta & Eucalyptus Diversifolia

In the present work, four techniques of extraction: microwave-assisted hydro distillation (MAHD), supercritical CO2 extraction (SCE), accelerated solvent extraction (ASE) and conventional extraction (HD) were applied to ground three species of Eucalyptus leaves and compared for extraction duration, extraction yield, and chemical composition of the extracts as well as their biological activities.

Joana: can this be applied to other aromatic or medicinal plants? PLEASE ADD A SENTENCE ABOUT THIS TO CLARIFY!More



Conservation, multiplication and utilization of Medicago arborea L.

Medicago arborea leafs and flowers

Medicago arborea, a naturalized species, was selected for its pastoral and high ecological interest: it is a nitrogen fixer and a cold-, drought- and salt-tolerant plant species (Sibole et al. 2003). It tolerates frost conditions and low temperatures as well as drought conditions and high temperatures. It’s an important species regarding its symbiosis with nitrogen fixation bacteria. The species had always demonstrated its importance as a forage species and its quality in feeding the animal.  The main objective of this work is to master the techniques for multiplying and...More
