“…Two types of forest feedstocks are available for bioethanol production: those are hardwoods and softwoods. Softwoods, such as pine, spruce, cypress, fir, and others have lower density and can grow on a higher rate, while hardwoods, such as oak, willow, poplar, cottonwood, and others are angiosperm and mostly deciduous [ 48 ]. Cottonwood is believed to be the most suitable woody feedstock for bioethanol production, since it is the most productive tree with several important advantages, such as a large amount of clones, restoration possibility by multiple cuttings, and uniformity in planting material quality [ 49 ].…”

As the need for non-renewable sources such as fossil fuels has increased during the last few decades, the search for sustainable and renewable alternative sources has gained growing interest. Enzymatic hydrolysis in bioethanol production presents an important step, where sugars that are fermented are obtained in the final fermentation process. In the process of enzymatic hydrolysis, more and more new effective enzymes are being researched to ensure a more cost-effective process. There are many different enzyme strategies implemented in hydrolysis protocols, where different lignocellulosic biomass, such as wood feedstocks, different agricultural wastes, and marine algae are being used as substrates for an efficient bioethanol production. This review investigates the very recent enzymatic hydrolysis pathways in bioethanol production from lignocellulosic biomass.

“…The general characteristics of the plants, i.e., combustion type and temperature, and the type of wood biomass are given in Table 2 . The combustion technologies and the type of biomass used affect the chemical composition of the WBA [ 13 , 22 ], which directly affects the possibility of mortar hardening and thus the applicability of WBA as a lime substitute.…”

“…The compliance of the tested binders with the criteria listed in Table 1 , taking into account the WBA content in the binder, was carried out as follows [ 22 ]: X i = X CFA × (%/100) CFA + X WBA × (%/100) WBA where: X i expressed value of observed physical or chemical property X CFA value of the physical or chemical property for CFA X WBA value of the physical or chemical property for used WBA (%/100) CFA content of CFA in the mixture, expressed in percentages (%/100) WBA content of WBA in the mixture, expressed in percentages …”

“…The chemical composition of WBA is also highly variable and depends on the combustion technology. Therefore, quality control is essential in the production and application of biomass ash, even compared to coal fly ash, which is widely used regardless of the variations in its chemical composition [ 17 , 22 ]. Table 1 shows the requirements for HL according to the standard EN 459-1 [ 23 ], i.e., the properties of binders, pastes and mortars that must be met for the material to be classified as HL.…”

“…Inspired by a small number of research studies conducted on cementless mortars using WBA [ 13 , 22 ], the overall objective of this research was to produce mortar using WBA and coal fly ash (CFA) and presents a continuation of research reported at [ 25 ]. Specific objectives were: (a) selection of suitable WBAs by analyzing their chemical composition, (b) preparation of an alternative binder system by combining WBA and CFA, (c) analysis of the setting rate and volume stability of such systems.…”

Reducing greenhouse gas emissions and dependence on fossil fuels is the cornerstone of all European climate and energy strategies. Consequently, renewable energy sources are becoming more competitive with fossil fuels. The largest source of bioenergy in the European Union is biomass-fired power plants. Therefore, the European coal phase-out strategy led to an increased use of wood biomass as a sustainable fuel, generating large amounts of wood biomass ash (WBA). In the research studies reported so far, WBA has been mainly used in cementitious composites. However, given the similarities between the chemical composition of WBA and hydraulic lime (HL), this research focused on its potential classification as a building lime. Overall, three different sources of fly WBA were considered for the preparation of binders as mixtures of WBA and coal fly ash (CFA) in different ratios. The contribution of each binder mixture on the paste and mortar properties was analyzed based on the chemical composition, setting time, volume stability, and contribution to the mortar strength (compressive and flexural). In general, it can be concluded that the studied binders can meet the criteria of EN 459-1. However, special attention should be paid to the volume deformations and the setting time.

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.
