    Wood is a sustainable and renewable material with a lower carbon footprint than other materials. However, its transformation into engineered products industrially, such as glulam, requires kiln drying, which implies energy consumption and loss of wood resources. Recent research has carried out green gluing, a variant of glulam characterized by a reduction of the drying process. Interest in it has increased as a new method of improving the use of wood that does not meet industry standards. It has been accomplished by developing adhesives for wood with high moisture content, but the variables involved are not yet completely understood. Therefore, conducting further research and analyzing the relevant publications is necessary. Bibliometric analysis was the method used, which included documents stored (from 2000 to 2020) in Scopus (Elsevier), Web of Science (Clarivate Analytics), and SciELO Citation Index (Web of Science—Clarivate Analytics) databases. The bibliometric analysis identified three main areas to develop: glue wood, glue properties, and analysis methods. The studies were concentrated on a few countries and research groups. The main progress has been made in synthetic and natural (or environmentally friendly) glue topics. The improvement of technique could enlarge the opportunities for collaboration and innovation in wood material science.

    Native wood revaluation through green gluing: a systemic review
    (2022) Rodríguez Grau, Gonzalo; Pinto González, Francisca; Cortés Rodríguez, Patricio; Marín Uribe, Carlos Rodolfo; Pontificia Universidad Católica de Chile. Escuela de Construcción Civil; Pontificia Universidad Católica de Chile. Bibliotecas UC
    The objective of this study is to identify more representative variables that can be considered during the gluing process of wood from native forests in Chile with the green gluing technique, given that it has the potential to produce structural elements for the construction industry from fine woods that are currently undervalued. In order to do so, the methodology consisted of applying a Systematic Literature Review (SLR) and a bibliometric mapping of scientific publications (2000-2019) indexed in the Scopus database. As a result of the analysis, 3 thematic lines were established: "Environmental Impact", "Performance" and "Variable-Influenced Performance". Based on these lines, the most representative variables that determine the production of wet glue laminated wood, were extracted. These identified variables will be the basis for the elaboration of a green gluing methodology that has been adapted to the native timber gluing process.

    Solerillas de hormigón y plástico reciclado para la conformación de jardineras: hacia un producto más sustentable
    (2021) Valderrama Ulloa, Claudia; Parra Henríquez, Francisco Andrés; Marín Uribe, Carlos Rodolfo; Rodríguez Grau, Gonzalo
    El principal objetivo de este estudio es reutilizar el hormigón de desecho de prácticas académicas y plásticos reciclados tipo PET (Polietileno Tereftalato) para la conformación de jardineras. Se propuso un diseño innovador de solerillas con pesos que oscilan entre 15 y 25 kg. Se caracterizan las mezclas de hormigón (0, 0,5 y 1,0% PET) y se hace un análisis de los aspectos de sustentabilidad de la solución. Los resultados indican que es posible alcanzar la resistencia mínima a la compresión de 15 MPa para todas las mezclas estudiadas. Con esta solución, se reutilizan 6 toneladas de hormigón al año, promoviendo el reciclado de hasta 40 botellas PET por solerilla, evitando anualmente la emisión de 40,66 kgCO2 y el consumo energético de 1.345,40 kWh. Se concluye que la solución de elementos prefabricados tipo solerilla para la construcción de jardineras es una alternativa para reducir hormigones en estado fresco que se desechan y para reciclar plástico del tipo PET.
