“…Given the substantial environmental burdens associated with the ongoing crisis, the current study is aimed at investigating the environmental impacts of medical face mask production using the LCA approach and based on the available data. It should be mentioned that LCA, as a critical tool, could be effectively used to assess the available systems and compare the different systems from an environmental point of view (Prasad et al, 2020). Notably, LCA's role in assessing the environmental impacts of any production systems is vital both in the scientific and industrial communities (Moustakas et al, 2020).…”

the World Health Organization identified SARS-CoV-2 as a public health emergency of global concern. Accordingly, the demand for personal protective equipment (PPE), including medical face masks, has sharply risen compared with 2019. The new situation has led to a sharp increase in energy demand and the environmental impacts associated with these product systems. Hence, the pandemic's effects on the environmental consequences of various PPE types, such as medical face masks, should be assessed. In light of that, the current study aimed to identify the environmental hot-spots of medical face mask production and consumption by using life cycle assessment (LCA) and tried to provide solutions to mitigate the adverse impacts. Based on the results obtained, in 2020, medical face masks production using fossil-based plastics causes the loss of 2.03 × 10 3 disability-adjusted life years (DALYs); 1.63 × 10 8 PDF*m 2 *yr damage to ecosystem quality; the climatedamaging release of 2.13 × 10 9 kg CO 2eq ; and 5.65 × 10 10 MJ damage to resources. Besides, annual medical face mask production results in 5.88 × 10 4 TJ demand for exergy. On the other hand, if used makes are not appropriately handled, they can lead to 4.99 × 10 5 Pt/yr additional damage to the environment in 2020 as determined by the EDIP 2003. Replacement of fossil-based plastics with bio-based plastics, at rates ranging from 10 to 100%, could mitigate the product's total yearly environmental damage by 4-43%, respectively. Our study calls attention to the environmental sustainability of PPE used to prevent virus transmission in the current and future pandemics.

In China, the non-exploitation of bioenergy poses major problems and challenges. To solve bioenergy problems, considerable efforts have been made to expedite the construction of large-scale crop residue utilization projects. In this study, three principal supported modes of large-scale crop residue utilization projects were taken as empirical cases in Hubei province bioenergy planning. In terms of the overall benefit and sustainable development, a third-grade evaluation index system was established. The analysis was carried out using the analytical hierarchy process, principal component projection, and grey relational analysis. The conclusion indicates that according to the evaluation values, the sequence from best to worst was crop residue biogas project, crop residue briquette fuel project, and crop residue gasification project. Nevertheless, there was no remarkable difference in the overall evaluation values. The biogas project had certain advantages in terms of the production cost, soil improvement, and expenditure saving, whereas the gasification project was comparatively insufficient in environmental efficiency, product benefit, by-product disposal, and technical rationality. According to actual evaluation results, the unilateral determination approach of the single weight index can be seen as being overcome through the unified adaptation of the evaluation methods. The research results can serve as a reference for making investment decisions to build large-scale crop residue utilization projects.

“…Bioenergy generation is construed as a viable strategy in crop residue management on account of the factors like increasing generation of crop residues, growing need for renewable energy trajectory and decentralized power generation, and nexus between bioenergy generation and employment opportunities [5,8,19,20]. Bioenergy from crop residues is generated through technologies including but not limited to combustion, biomass gasification, pyrolysis, fermentation and anaerobic digestion [1,21]. Extensive literature is available on the technologies used for bioenergy generation.…”

Crop residues are sustainable feedstock for bioenergy production. The gross crop residue potential generated in India is 696.38 million tonnes/year. Cereal crops generate about 364.27 million tonnes/year of crop residues. Cereal crops (rice, wheat, sorghum, pearl millet, maize), sugarcane and horticultural crops (coconut, areca nut, banana) are found to have immense crop residue generation potential. Crop residues of 209.69 million tonnes/ year are available as surplus and can be explored for bioenergy generation. Cereals and sugarcane account for 75% of surplus crop residues. Spatial variations existing between states in terms of surplus crop residue generation are due to crop acreage and crop productivity. Uttar Pradesh generates 116.69 million tonnes/year of gross crop residues and 41.76 million tonnes/year of surplus crop residues. States like Punjab,
