THIS RESEARCH AIMED TO SYNTHESIZE FINDINGS ON CORPORATE SOCIAL RESPONSIBILITY (CSR) AND ITS RELATIONSHIP WITH BUSINESS COMPETITIVENESS IN PERU BETWEEN 2020 AND 2024, IDENTIFYING TRENDS AND GAPS TO GUIDE FUTURE RESEARCH. THE PRISMA METHODOLOGY WAS EMPLOYED, CULMINATING IN THE SELECTION OF 25 RELEVANT ARTICLES, WITH 60% SOURCED FROM SCOPUS AND 40% FROM WOS. THE "JOURNAL OF COMPETITIVENESS" EMERGED AS THE MOST FREQUENTLY REFERENCED PUBLICATION (12%), FOLLOWED BY THE "REVISTA VENEZOLANA DE GERENCIA" AND THE "JOURNAL OF CLEANER PRODUCTION" (8% EACH). SPAIN LED THE COUNTRY RANKINGS WITH 12% OF STUDIES, WHILE 2020 WAS THE MOST PROLIFIC YEAR (27.98%), FOLLOWED BY 2023 (24.02%). A BIAS RISK ASSESSMENT REVEALED THAT 70% OF THE STUDIES EXHIBITED LOW RISK, 20% UNCERTAIN RISK, AND 10% CRITICAL RISK.

THE FINDINGS DEMONSTRATE THAT CSR SIGNIFICANTLY ENHANCES COMPETITIVENESS BY INFLUENCING ORGANIZATIONAL PERFORMANCE FACTORS SUCH AS REPUTATION, BRAND IMAGE, AND CUSTOMER LOYALTY. IN ECUADOR'S MANUFACTURING SECTOR, CSR AND GREEN INNOVATION DRIVE COMPETITIVENESS BY FOSTERING EMPLOYEE WELL-BEING AND LEVERAGING FORMAL CSR TOOLS FOR DIFFERENTIATION. SIMILARLY, IN SPAIN'S AGRICULTURAL SECTOR, THE INTEGRATION OF CSR WITH SUSTAINABLE TECHNOLOGICAL INNOVATION HAS PROVEN TO BOOST BOTH COMPETITIVENESS AND SUSTAINABILITY. THESE RESULTS UNDERSCORE THE PIVOTAL ROLE OF CSR IN SHAPING SUSTAINABLE BUSINESS STRATEGIES AND SECURING COMPETITIVE ADVANTAGES IN DYNAMIC MARKETS.

The purpose of this study was to evaluate the efficiency of the use of Opuntia ficus-indica and Caesalpinia spinosa in the partial elimination of turbidity in wastewater. To this end, tests were carried out with different doses of both natural coagulants in wastewater. An experimental design was used with five treatments for each coagulant, evaluating parameters such as turbidity, pH, conductivity and temperature before and after treatment. The values obtained were compiled in a previously validated record card, which allowed the measurements of each parameter evaluated to be recorded systematically and reliably. The results showed that the treatment with Caesalpinia spinosa was the most effective, achieving a turbidity removal of 99.34%, with final turbidity values between 4.29 UNT and 5.09 UNT, complying with the limits established by the Environmental Quality Standards (ECA) of Supreme Decree 004-2017-MINAM. On the other hand, the treatment with Opuntia ficus-indica showed a turbidity removal of 92.2%, but the final values remained above the limit of 5 UNT, placing it in subcategory A2. In addition, pH, conductivity and temperature remained within the allowable limits, suggesting that both coagulants are suitable for wastewater processing in the context of potabilization. In conclusion, Caesalpinia spinosa showed superior efficiency in turbidity reduction, being more suitable for this purpose.

Fuel is an essential substance due to its wide range of applications in different productive sectors. As a result, various environmental challenges have arisen, such as climate change and the increase in global temperature. Therefore, the objective of this research was to evaluate the production of bioethanol from Musa paradisiaca shell waste using different amounts of Saccharomyces cerevisiae. To do so, a quantitative approach methodology was applied with a 3×2 factorial experimental design. The procedure included mechanical pretreatment, hydrolysis and fermentation. As a result, it was found that the highest concentration of bioethanol obtained had a value of 6,85 g/L with two grams of yeast. Regarding the °Brix, an average of 8.20 was reached in all experiments at the end of hydrolysis. Subsequently, after fermentation with one gram and two grams of yeast, these values ​​were reduced to 3 °Brix and 2 °Brix. Similarly, in relation to pH, an average decrease was reported from 5,77 to 4,77 and 3,77, respectively. In conclusion, the statistical analysis showed that yeast, independently, significantly influences the bioethanol concentration, °Brix and pH.

The proposal for the productive use of residual sludge was carried out in collaboration with Servicios Aguas de Comayagua (SAC).

The objective was to characterize and analyze the potential for reusing residual sludge from the water treatment plant as a substitute material for fine aggregate in the production of fired clay bricks and/or as fertilizer in school gardens. This initiative aims to promote sustainability and reduce pollution in the department of Comayagua, Honduras.

For the research development, a total of four residual sludge samples were obtained. Despite containing nutrients and organic matter, the analysis determined that they are not a viable option as fertilizer for school gardens due to the presence of pathogens that hinder seedling growth. However, they were found to be an excellent substitute for fine aggregate in the production of fired clay bricks, as the analyzed results indicate that one of the mixtures possesses characteristics close to the classification of ASTM C62-23 standards.

The presented systematic review analyzes the influence of bioremediation of heavy metals as a water treatment technique from 2015 to 2025. The main and specific objectives were to assess the contribution of bioremediation in the removal of chemical pollutants from water, as well as its impact from a sustainable and effective perspective. An in-depth exploration was conducted in the Web of Science database, using specific keywords and inclusion and exclusion parameters. The results indicate that bioremediation techniques are sustainable and efficient methods, with heavy metal adsorption values reaching up to 100% when using biological organisms, improving water quality for reuse or safe discharge into the environment. However, limitations were also identified, such as the performance of microorganisms depending on the adsorbate or adsorbent biomaterials, which may be affected by factors such as pH, temperature, and high concentrations of toxic substances. The need for the application of nanoparticles or optimized microorganisms may be limited by regulations and have a negative ecological impact. The contribution of this review to the literature is significant, highlighting both the advantages and limitations of bioremediation. Future research is suggested to delve deeper into the optimization of bioremediation execution conditions, to improve the resistance and adsorption capacity of biological organisms, the use of nanotechnology to enhance the process, and the development of strategies for the recovery and recycling of adsorbed metals

In the juice industry, the management of organic solid waste, such as peels and pulp, along with high water consumption, were critical environmental factors. Implementing sustainable practices was essential to minimize these impacts and preserve environmental balance. Inefficient practices, such as excessive water use and improper waste disposal, contributed to soil and water contamination, affecting local ecosystems. To address these challenges, improvement strategies were proposed, including time studies, OWAS, Guerchet, and plant redistribution, optimizing production, reducing costs by 78.48%, and enhancing sustainability in the juice processing industry.
