The escalating generation of construction and demolition waste (C&DW) owing to the rapid increase in population and the per capita generation (PCG) index as an urban development metric has triggered numerous research endeavors aimed at formulating effective mechanisms and strategies to manage this waste stream. This study aims to assess the efficacy of economic instruments in promoting C&DW reuse and diverting waste from sanitary landfills using the System Dynamics (SD) tool and scenario simulations spanning the period 2020 to 2040 in the municipality of Serra, Espírito Santo (ES). Our findings reveal that the PCG index exerts a staggering 84-fold greater influence on C&DW generation compared to that of population growth. Additionally, we observe that the implementation of a public policy, such as a landfill tax, can substantially augment aggregate recycling by 124 times when comparing the highest tax rates (6%) to the lowest tax rates (2%). Nevertheless, even under the best-case scenario, our analysis demonstrates a potential rise of 76,000 tons of illegal dumping, leading to an approximate cost increase of 10 million dollars for C&DW management until 2040. To enhance future investigations, we suggest the inclusion of penalties and subsidies in the model to comprehensively evaluate their impact on C&DW management alongside the taxation applied to landfill disposal. This multifaceted approach can provide valuable insights for devising more effective waste management strategies.

With the growth of the number and financing scale of green bonds, the economic performance of green bonds has become a hot issue of social concern and academic research. As a policy tool, green bonds can influence the business strategy of enterprises. Taking green bonds as an example, this study tests the inhibitory effect of green finance on corporate financialization using a difference-in-difference model. The results show the following: (1) green bonds can significantly inhibit the financialization level of issuers; (2) research and development expenditure of corporate entities is an intermediary way for green bonds to restrain corporate financialization; and (3) heterogeneity test found that the inhibitory effect of green bonds on the corporate financialization of issuing corporates was mainly reflected in state-owned corporates, heavily polluting ones and those with high equity incentive. The study clearly identifies the causal relationship and mechanism between green bonds and corporate financialization, and provides a new perspective for understanding the formation mechanism and solution path of corporate financialization from the perspective of green finance. Therefore, it is necessary to promote green bonds, ultimately helping to achieve green development.

For many purposes, water is a valuable and necessary natural resource. There are many uses for water. Its application calls for a good quality. The aim of this study is to assess the physico-chemical and bacteriological quality of wells in the area of Al Hoceima, Morocco. A number of 10 sampling points were studied. Several parameters were measured including pH, electric conductivity, dissolved oxygen, sodium, ammoniacal nitrogen, phosphate, temperature, nitrates, nitrates, sulfates, chlorides, and other bacteriological parameters as fecal coliforms, total coliforms, and fecal streptococci. Samples were found contaminated by pollution coming from agricultural origin regarding the concentrations of Clexceeding 2565.7 mg/L. Nitrites and nitrates levels were not of a concern. The majority of the wells were below the standards limits for human consumption.

The pharmaceutical industry has important reasons to adopt sustainability and reduce its environmental footprint. Joining the trend, the Indian pharmaceutical industry is also embracing a cleaner and greener transition and is adopting responsible manufacturing. Adoption of data-driven approaches like Life-Cycle Analysis (LCA) to understand the environmental footprint associated with synthesis of an Active Pharmaceutical Ingredient (API) can help the manufacturers to review and improve their legacy processes. Prioritizing process optimization can result in better environmental performance along with economic, social and competitive advantages. This paper presents a data-driven practical approach for implementing an LCA based method for making the production process greener while comparing environmental impacts under different categories. Accordingly, the approach and methodology adopted and the results highlighted are expected to give an idea to pharmaceutical manufacturing companies to innovate and optimize their approaches to enhance environmental performance within a set of system boundaries. The present study demonstrates 5% improvement in yield for Celecoxib (API) synthesis and the resulting improvement in environmental performance. The framework presents an alternative method to reduce waste, energy consumption and emissions to minimize the environmental burden. Accordingly, the system boundaries cover cradle-to-synthesis stages of the API manufacturing. The effectiveness and potential of using LCA in analyzing and optimizing the pharmaceutical manufacturing process alongside improving the environmental performance with higher yield has been shown. The need to integrate LCA methodology with product and process development has thus been shown. Process optimization through greener methods of API manufacturing can be guided by such framework studies.

Steam reforming is currently the most common process for hydrogen production, but its use is mainly limited to fossil-based fuels such as natural gas. In an effort to diversify the hydrogen matrix, alternative sources have been considered, among which butanol appears as a potentially renewable source. The present study provides a detailed thermodynamic discussion about the operational parameters influencing hydrogen yield and heat consumption in an Aspen Plus® simulated cycle. The effect of key operational variables over hydrogen yield and heat duty was initially assessed through Response Surface Methodology (RSM) and later optimized with the Multi-Objective Lichtenberg Algorithm (MOLA). Results indicated that, for most of the operational range, reducing the steam/butanol molar ratio had a stronger influence on decreasing the heat duty required for optimal hydrogen production. The optimal temperature was kept at 800 °C even after the steam molar ratio reached lower values (4-4.5 mol/mol). At high temperatures and steam ratios, higher water gas shift temperatures were more efficient because they avoided unnecessary heat removal, despite losses in hydrogen production due to chemical equilibrium. The Pareto also presented a nearly vertical region, which indicated that hydrogen yield could not be significantly increased after 94.4%.
