Summary The purpose of this paper is to investigate the perspective of using wood waste, especially the one that resulted from the construction and demolition activities, to produce sustainable bioenergy. The context of this research is characterized by a more accelerated need for development, a growing need for energy to fuel all human activities, and a greater awareness of the pressure on the environment and the negative effects produced. One of the major challenges for environmental protection is the issue of mitigating CO2 emissions, and among the biggest contributors to the CO2 emissions is the construction industry. Given the current rhythm of society development, a decrease in construction activities is not possible so a solution can be better management of the waste produced in various stages. If the need for better waste management is joined with the need for more sustainable energy, then using waste to produce bioenergy seems like a good solution. This study focuses mainly on wood waste and to respond to the research purpose it uses bibliometric literature search, scientometric analysis, and in‐depth discussions. The data were obtained by interrogating the ISI Web of Science database using the keywords “bioenergy”, “wood waste” and “construction and demolition” as search criteria. The extraction of data was done using the PRISMA method and processed with VOSviewer and Bibliometrix software. The processing of the data was done so to obtain information related to the importance of the research topic given by the number of publications, the most studied topics revealed by a keywords co‐occurrence analysis and a trend topic plot, as well as the world scientific productions on the studied topics. The main results indicate a significant increase, in the last years, of the interest in the studied topics, all over the world. Wood waste is considered as a direct combustion fuel or as a raw material for components of fuels used to produce energy, as well as components for new building materials. Given the limitations of other renewable energy sources, wood biomass is a subject that must be considered more in the future. The use of wood waste as biomass for the production of bioenergy can be a very good solution that will bring the advantage of both ensuring a renewable source of energy and at the same time decreasing the impact of the building industry on the environment.

“…The most used way is in the composition of wood particle boards. Particleboards can be obtained by using waste wood formwork, as shown in (Hossain et al, 2018) or in (He et al, 2019), and can be transformed into cement-bonded particleboards using MOC (magnesium oxide cement) as a green cement-based binder (Maier and Manea, 2022), so it presents a practical and environmentally friendly option for the management of construction wood waste. Other materials, such as tire fibers or biomass ash, can be added to the mixture of chipboard in addition to wood waste (Amiandamhen et al, 2021).…”

The purpose of this paper is to investigate the possibilities of implementing the principles of circular economy in the wood construction industry. The general context of the research is characterized by the new and more demanding challenges regarding the environmental protection issues arising from the current rhythm of development of modern society. One way of responding to these challenges is to transform our consumption society into a more sustainable one. The circular economy has recently become a focal point of European Union policy for transforming production and consumption toward a more sustainable and environmentally friendly direction. The circular economy is mainly related to the use of materials after their life cycle and must be implemented at the design stage of a product or system. However, the meaning and implementation of the concept often remain vague and ambiguous. The construction industry is one of the sectors that use a lot of natural resources, put a lot of pressure on the environment, and generates large amounts of waste. The focus of this research is on wood construction and the possibilities of better use of the potential of wood. Through the implementation of the circular economy principles, wood waste can be used furthermore in the product industry and if further research will be carried out it will bring great benefits to businesses, including economic gains in addition to the environmental ones.

“…Magnesium oxychloride cement (MOC) is an environment-friendly magnesia cementitious material prepared by lightly burning magnesium oxide, magnesium chloride and water [15]. Due to its fast-setting speed, high mechanical strength, good wear resistance, salt resistance and halogen corrosion, simple production process, and low cost, it is widely used in construction materials, biological materials, and other fields [16][17][18]. e salt lakes in the Qinghai area of China have sufficient reserves of magnesium salts and high grades [19].…”

Due to the poor performance of ordinary Portland cement (OPC) as a solidified soil road and the large pollution in the production process, environment-friendly magnesium oxychloride cement (MOC) was used as the soil curing agent to prepare the solidified soil, exploring the optimal ratio of various raw materials when MOC is used as a curing agent. Analyzing the properties of MOC solidified soil in the application of road subgrade. This paper tests compaction, mechanical properties, and durability of the MOC solidified soil, simulates the development trend of 7 days unconfined compressive strength of MOC solidified soil, and then analyzes the hydration process and strengthens the formation mechanism of MOC in solidified soil. The study found that the addition of MOC as a curing agent to the soil can effectively improve the compaction and mechanical properties of the soil. Matlab simulation found that when the MgO content is 5.5% to 6% and the ratio of raw materials MgO, MgCl2, and H2O is 2.45 : 1 : 14 to 6.3 : 1 : 14, the performance of MOC solidified soil is excellent. Fitting UCS data, it is found that MOC solidified soil has early strength characteristics. The excellent compaction and mechanical properties of MOC solidified soil are due to the formation of a small amount of phase 5 and layered Mg(OH)2 by the hydration of MOC, and the formation of amorphous gel with SiO2 in the soil. This reaction improves soil compaction and reduces internal porosity from a microscopic perspective. The strength loss rate of MOC solidified soil is higher after immersion in water at the initial stage of curing, but it is still better than that of traditional cement-based solidified soil. Poor performance after immersion in water is associated with disruption of the network-like structure. As an environment-friendly soil curing agent, MOC can be used in engineering practice with low environmental humidity.
