“…However, these works mainly focused on the modified fillers' impact on WPCs properties, without the analysis of their environmental impact. Nevertheless, health and safety issues should also be addressed, which will enable the optimization of fillers' modification and development of more environmentally friendly processes in the future (Doustmohammadi and Babazadeh 2019;Keskisaari and Kärki 2016;Quitadamo et al 2019).…”

This study presents an analysis of the structure and properties of different types of lignocellulosic fillers modified by isophorone diisocyanate (IPDI) to provide insights into the possibility of their application to the manufacturing of wood polymer composites (WPCs). Moreover, it deals with the environmental aspects of modified fillers, by assessment of volatile organic compounds (VOCs) emitted during modification, as well as from final products. Three types of commercially available lignocellulosic fillers were modified with different content of IPDI (from 1 to 15 wt%) using the internal mixer. The main compounds detected in the air during modifications were terpenes and terpenoids. No IPDI was detected, which is very beneficial considering its toxicity. On the other hand, IPDI was emitted from modified fillers at a slightly elevated temperature of 40 °C, which was associated with a significant rise in its vapor pressure. Successful modification of fillers was confirmed by FTIR spectroscopy and thermogravimetric analysis. Performed modifications of lignocellulosic fillers with IPDI had a relatively small impact on their particle size and color properties. Such an effect can be considered beneficial for the mechanical performance and appearance of WPCs, which could be potentially manufactured using IPDI-modified lignocellulosic fillers.

“…La incineración de la harina de madera para generar energía no solamente representa un combustible de bajo valor, sino que produce esmog secundario sumamente dañino [2] . Reciclar y reutilizar es uno de los procesos para reducir la contaminación ambiental, siendo este último uno de los objetivos principales de los compuestos de madera-plástico (Figura 2), pues tan solo un fabricante de puertas hechas con WPC previene anualmente la destrucción de tres millones de árboles [20] . Del mismo modo, los residuos de madera como reforzadores de materiales compuestos podrían realizar una importante contribución al reciclado y reducción de emisiones de CO 2 [21] .…”

Los compuestos de madera-plástico han sido objeto de interés por parte de investigadores por sus propiedades mejoradas, en comparación con los productos basados únicamente en plástico o madera. Sin embargo, durante algunos años se han estudiado los efectos de algunos nanorrellenos sobre estos compuestos. La presente investigación tiene como objetivo la revisión de las investigaciones más relevantes en trabajos publicados en revistas científicas sobre los efectos de los nanorrellenos en los compuestos de madera y plástico. El material bibliográfico consultado se encuentra entre los años 2011 y 2021. En este estudio se discuten los beneficios ambientales, la limitación de las aplicaciones y los efectos de algunas nanopartículas en estos compuestos con plástico virgen y reciclado. Se concluye que los nanocompuestos de madera-plástico son una excelente opción de material con aplicaciones potenciales. No obstante, se sugiere visualizar las alternativas que existen para el uso de nanocompuestos madera-plástico en el diseño de producto.

“…The network structure of industrial exchange is particularly relevant to the recent discussion surrounding circular economy . The circular economy aims to make production processes more sustainable (Ghisellini et al., 2016; Webster, 2017) by enhancing reuse, recycling, and process integration within and across value chains (Doustmohammadi and Babazadeh, 2020). This concept was first envisaged in the 1990s, in the domain of sustainable resource and waste management (Pearce & Turner, 1990; Schwarz & Steininger, 1997).…”

Networks of mass flows describe the basic structure of ecosystems as food webs, and of economy as input-output tables. Matter leaving a node in these networks can return to it immediately as part of a reciprocal flow, or completing a longer, multi-node cycle.Previous research comparing cycling of matter in ecosystems and economy was limited by relying on unweighted or few networks. Overcoming this limitation, we study mass cycling in large datasets of weighted real-world networks: 169 mostly aquatic food webs and 155 economic networks. We quantify cycling as the portion of all flows that is due to cycles, known as the Finn Cycling Index (FCI). We find no correlation between FCI and the largest eigenvalues of unweighted adjacency matrices used as a cycling proxy in the past. Unweighted networks ignore the actual flow values that in reality can differ by even 10 orders of magnitude. FCI can be decomposed into a sum of contributions of individual nodes. This enables us to quantify how organisms recycling dead organic matter dominate mass cycling in weighted food webs. FCI of food webs has a geometric mean of 5%. We observe lower average mass cycling in the economic networks. The global production network had an FCI of 3.7% in 2011. Cycling in economic networks (input-output tables and trade relationships) and food webs strongly correlates with reciprocity. Encouraging reciprocity could enhance cycling in the economy by acting locally, without the need to perfectly know its global structure.
