“…The development studies identified in the literature on CU could be used to improve the concept of CE as well [10,51,54,58] and vice versa. Hence, we suggest that CU should be considered a basic concept within CE and particularly in the circular bio-economy, in which investigations are performed on raw material efficiency performance over multiple-use phases.…”

“…A method for estimating the expected utilization time for a material has been proposed by Yamashita et al [52]. Mantau [10] introduced the method wood resource balance, and Knauf [53] questioned whether the model accurately reflects reality, proposing enhancements for the original wood resource balance model. Mellor et al [54] developed a model for supporting decision-making on which material/product could be best used for specific additional purposes, and Vogtländer et al [55] presented an LCA-based model that could be used to run integrated analyses of the product chain, its recycling systems, and its waste treatment systems at the endof-life of a product.…”

Purpose of Review The aim of this study was to analyze the differences and similarities between the concepts circular economy (CE) and cascading utilization (CU) and the interactions between these concepts. The method chosen for this study was a qualitative content analysis, which was conducted on academic CU publications that appeared between 1990 and 2016. To identify connections between CU and CE, the findings of this study are compared to the results of a recent review on CE. Recent Findings From the perspective of the broader goals of CE and CU, both concepts promise to increase resource efficiency by supporting the multiple use of a resource. Research conducted on both concepts has included analyses of the environmental impacts of the CU or CE systems and descriptions of frameworks and tools used to develop cascade chains or measure the circularity of a given resource. Even though the concepts have many similarities, the research has mostly been conducted independently, and the number of connections between the two concepts is surprisingly low. Summary In general, the results of the analysis supported the hypothesis that CU and CE have many parallels and similarities. The CU concept addresses primarily resource management whereas CE provides a more holistic approach. Practically, the publications on CE include considerations of many kinds of resources, whereas publications on CU include a stronger focus on bio-based materials. Despite these differences, CU was shown to clearly fit into the CE concept in that it provides a specific focus on the utilization possibilities (e.g., reuse, recycling, and up-cycling) of a given resource. The term CU may be used whenever one or more of these measures are used.

The results of experimental studies of various geometric shape wood biomass single particles ignition processes (on the example of a cylinder and a cube) are presented. According to the results of the experiments, it has been stated that the shape of the fuel particle can influence the characteristics and conditions of ignition, but it is insignificant. It has been demonstrated, that in most cases cylindrical particles ignite faster than cubic particles. However, in this respect, two ignition modes are set: high temperature (the cube fires up faster) and low temperature (the cylinder ignites faster).

“…At the moment reliable data on wood flows and indicator values are not available, but considering a growing amount of related studies [37][38][39][40], it would be worthwhile to use regional or European scale averages to estimate such effects. The ToSIA methodological framework could be used to estimate those effects, if robust enough data on wood flows were available.…”

Climate change and transition towards a bioeconomy are seen as both challenges and opportunities for the forest-based sector in Europe. Transition towards a bioeconomy will in most cases rely on intensified use of renewable resources and/or advancement in technology. However, how can the intensified use of renewable resources be combined with climate change mitigation measures to increase carbon sinks in the forest-based sector? Additionally, what are the possible socio-economic and environmental impacts of intensified wood use? In this study, we examined the impacts of increased wood utilisation in Lithuania. The objective of this study was to assess the effects of increased domestic wood utilisation on: (i) employment; (ii) the economic performance of the sector; (iii) carbon in forest biomass and soil; and (iv) carbon in harvested wood products (HWP). The system boundaries were set in accordance with international greenhouse gas reporting to include only domestic wood flows. We assessed alternative wood utilisation scenarios using a forest resource model and a tool to assess sustainability impacts of (wood) value chains, using country specific data on wood (carbon) flows. Our results indicate that increased wood use could lead to trade-offs between six selected indicators. Opportunities for employment and the economic performance of the forest-based sector improved in all scenarios due to increased wood utilisation. However, when forest fellings increased, the carbon stored in forests decreased, the carbon stored in HWP increased, but overall the total carbon stored in forests and HWP decreased. When considering also additional substitution effects until the year 2100, the scenario with reduced wood exports generated larger total climate change mitigation effects than the baseline. Our results suggest that increased wood utilisation might support Lithuania's bioeconomy through increased socio-economic benefits. National positive climate change mitigation effects could be gained only if additional actions to utilise more domestic wood for long-life HWP will be taken.
