While these two initiatives have received the support of the Colombian government through plans and strategies, little is known about the involvement of private companies. The aim of this study was to examine the CE and SDGs' implementation in the Colombian private sector. The entities linked with the United Nations Global Compact served as the study population, which was assessed by a semi-structured survey whose data was handled by descriptive and non-parametric statistics. Findings indicate that 75% of the entities are supporting the SDGs and adopting the CE model simultaneously. The food and transportation sectors show the highest levels of alignment towards CE, followed by mining and manufacturing. Waste management is the most implemented type of CE practice (65%), while supply chain management is the least (20%). The SDGs that receive the most attention are SDG 17, SDG 6, SDG 16, and SDG 12. Conversely, SDG 2 and SDG 5 receive the least support.","PeriodicalId":50565,"journal":{"name":"Dyna-Colombia","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135134521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The variables, liquidity risk (dependent) and capital structure (independent), were analyzed, based on a quantitative investigation with a correlational approach. The hypothesis was, H1: There is a positive relationship between the capital structure and liquidity risk. The population came from the accounting database as of December 31, 2016 of the Superintendencia de Sociedades, with a sample of 260 companies. It is concluded that the higher the level of indebtedness, the greater the liquidity risk of the company tends to increase, thus accepting the hypothesis established in the investigation. Derived from the analysis presented, recommendations are offered on the formulation of projects that can contribute to the improvement of the liquidity conditions of the companies analyzed.","PeriodicalId":50565,"journal":{"name":"Dyna-Colombia","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135135425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biogas utilization from landfills (BUL) is a widely adopted technique in the United States and some European regions.

This article aims to assess the electricity generation potential in Colombia's major cities and highlight the significant contribution of BUL in achieving public policies objectives for SD and climate change mitigation. The study underscores that Colombia undervalues the potential of BUL when formulating public policies, overlooking its substantial impact in fulfilling at least 14 of the 17 Sustainable Development Goals (SDGs).","PeriodicalId":50565,"journal":{"name":"Dyna-Colombia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135308272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Gartner Magic Quadrant for Hyperconverged Infrastructure in 2022 was used as a basis to achieve this objective. The leading vendors successfully implementing their solutions in the telecommunications sector were identified. Subsequently, the information gathered by consulting firms, the technology community, and experts in the field was contrasted to corroborate the evolution, advantages, and market trends.
