“…This result proves that, the higher the consumption of biomass energy source, the more the environmental degradation reduces. This outcome confirms the findings of Gyamfi et al, 35 Sakodie et al, 13 and Shahbaz et al, 42 but is contrary to the findings of Mahmood et al 40 and Solarin et al (2019).…”

“…The data for this analysis were collected from the World Bank Indices (http://www.databank.worldbank.org) to analyze long‐term and short‐term relations regarding economic growth (GDP), energy usage (EC), investment in the energy sector (INVE), and CO 2 emissions in E7 states. In line Danish and Wang 12 and Mahmood et al ., 40 data on biomass energy (consumption) are measured in tonnes per capita and retrieved from the Global Material Flow Database.

Inspired by the Sustainable Development Goals (SDGs), this study focuses on the need for responsible and clean energy consumption, climate change mitigation, and sustainable economic growth. To this end, the study investigates the connection between biomass energy consumption, real GDP, investment in the energy sector, and CO2 emissions in the emerging (E7) countries – China, India, Brazil, Mexico, the Russian Federation, Indonesia and Turkey – for the period 2000–2018. The study uses a battery of techniques, namely Pooled Mean Group‐autoregressive distributed lag, ordinary least square, dynamic ordinary least square, Fully Modified Ordinary Least Squares (PMG‐ARDL, OLS, DOLS FMOLS) and causality estimators, to measure the robustness of the conceptualized relationship among the variables of interest. Empirical results show that conventional energy from fossil fuel sources is a driver of CO2 emissions within the E7 economies. On the other hand, biomass energy consumption and investments in the energy sector decrease CO2 emissions. Furthermore, a feedback causality relationship between biomass energy consumption and CO2 emissions is observed. Similarly, a feedback causality relationship is seen between economic growth and biomass energy consumption. Our study's empirical findings reveal that biomass energy consumption mitigated CO2 emissions in the E7 economies that were examined, suggesting the pivotal role for biomass energy consumption in creating an eco‐friendly environment and environmental sustainability. This requires investment from the private sector, stakeholders, and government administrators in cleaner energy technologies initiatives like biomass. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Growing populations and related energy demand for societies across the world has resulted in great interest and funding for the development of sustainable energy sources [ 1 ]. One tapped source of sustainable energy involves conversion of lignocellulosic biomass into platform chemicals (such as glucose, xylose and furfural) for conversion into bioenergy, biomaterials, or biochemicals [ 2 ]. The viability of this resource derives from the fact that lignocellulosic biomass predominantly comprises carbohydrates of cellulose and hemicellulose [ 3 – 5 ].…”

Background During the dilute acid pretreatment process, the resulting pseudo-lignin and lignin droplets deposited on the surface of lignocellulose and inhibit the enzymatic digestibility of cellulose in lignocellulose. However, how these lignins interact with cellulase enzymes and then affect enzymatic hydrolysis is still unknown. In this work, different fractions of surface lignin (SL) obtained from dilute acid-pretreated bamboo residues (DAP-BR) were extracted by various organic reagents and the residual lignin in extracted DAP-BR was obtained by the milled wood lignin (MWL) method. All of the lignin fractions obtained from DAP-BR were used to investigate the mechanism for interaction between lignin and cellulase using surface plasmon resonance (SPR) technology to understand how they affect enzymatic hydrolysis Results The results showed that removing surface lignin significantly decreased the yield for enzymatic hydrolysis DAP-BR from 36.5% to 18.6%. The addition of MWL samples to Avicel inhibited its enzymatic hydrolysis, while different SL samples showed slight increases in enzymatic digestibility. Due to the higher molecular weight and hydrophobicity of MWL samples versus SL samples, a stronger affinity for MWL (KD = 6.8–24.7 nM) was found versus that of SL (KD = 39.4–52.6 nM) by SPR analysis. The affinity constants of all tested lignins exhibited good correlations (r > 0.6) with the effects on enzymatic digestibility of extracted DAP-BR and Avicel. Conclusions This work revealed that the surface lignin on DAP-BR is necessary for maintaining enzyme digestibility levels, and its removal has a negative impact on substrate digestibility.

[2] This resource's viability is based on the fact that lignocellulosic biomass is predominantly comprised carbohydrates of cellulose and hemicellulose, which can be depolymerized into monosaccharide platform chemicals. [3][4][5] Among the numerous lignocellulosic biomass candidates for conversion, bamboo is almost universally deemed viable because of its extraordinary growth rate, present availability, and high carbohydrate content (cellulose, 35-50% and hemicellulose, 15-35%).…”

Background: During dilute acid pretreatment, pseudo lignin and lignin form droplets which deposit on the surface of lignocellulose, and further inhibit its enzymatic hydrolysis. However, how this lignin interacts with cellulase enzymes and then affects enzymatic hydrolysis is still unknown. In this work, different fractions of surface lignin (SL) obtained from dilute acid pretreated bamboo residues (DAP-BR) were extracted by various organic reagents and the residual lignin in extracted DAP-BR was obtained by milled wood lignin (MWL) method. All the obtained lignin fractions from DAP-BR were used to investigate the interaction mechanism between lignin and cellulase using surface plasmon resonance (SPR) technology in order to understand how they affect enzymatic hydrolysisResults: Results showed that removing surface lignin significantly decrease the enzymatic hydrolysis of DAP-BR from 36.5% to 18.6%. The addition of MWL samples to Avicel decreased enzymatic hydrolysis of Avicel, while different SL samples showed a slight increase to its enzymatic digestibility.

The affinity constant of all tested lignin had good correlations (R2>0.6) with their effects on enzymatic digestibility of extracted DAP-BR and Avicel.Conclusions: This work reveals that the surface lignin on DAP-BR is necessary towards maintaining enzyme digestibility levels, and its removal has a negative impact on the substrate’s digestibility.
