“…Methane is significantly more potent than CO 2 in the short term, making it a significant concern for climate change. The technical literature has shown that methane emissions associated with fracking can be considerably high if proper management practices are not implemented [148][149][150][151][152]. These emissions can result from leaks in wells, equipment, and pipelines, as well as intentional releases during well purging.…”

This article presents an in-depth analysis of potential environmental risks associated with hydraulic fracturing operations within the “La Luna” formation in Colombia. Using the Conesa methodology, it assesses the environmental impacts of unconventional reservoir production in Colombia, including water usage, chemical additives, air emissions, and the potential for groundwater contamination. This study incorporates comprehensive data on geological characteristics, operational procedures, and environmental conditions specific to the region. This analysis highlights the need for a proactive approach to managing potential environmental risks associated with hydraulic fracturing in Colombia. The findings underscore the importance of implementing robust regulatory measures, comprehensive monitoring systems, and the industry’s best practices to mitigate and prevent adverse environmental impacts. This research contributes to the ongoing global dialogue on the environmental implications of hydraulic fracturing in regions with sensitive ecological conditions. The environmental impacts of unconventional reservoirs are widely recognized as a general consensus; however, the absence of applied studies with the rigor of an explicit methodology in Andean countries highlights the need for specific research in this region. This article addresses this gap by proposing a detailed and structured methodology to assess and mitigate environmental impacts in unconventional reservoirs. Emphasizing the importance of knowing the characteristics of reservoir fluids, this research highlights that this critical information is only revealed by drilling exploration wells and PVT (pressure, volume, and temperature) analysis. Obtaining this data is crucial for shaping specific mitigation measures, thus allowing for the formulation of a robust environmental management plan tailored to the conditions of the reservoirs in the Andean region. This precise and contextualized approach contributes to closing the knowledge gap and promotes more sustainable practices in the exploitation of unconventional reservoirs in this specific geographical context. The methodology used in this study proved its effectiveness by accurately quantifying the risks associated with each of the environmental alterations inherent to the hydraulic fracturing process in the La Luna formation. The results obtained allowed for the identification of the critical points most susceptible to environmental impacts, serving as a solid basis for the elaboration of an environmental management plan. This strategic approach not only enabled the delineation of specific mitigation measures but also facilitated the selection of the most appropriate locations for the implementation of the plan, maximizing the effectiveness of corrective actions. It is noteworthy that the successful application of the Conesa methodology in this unconventional reservoir context evidences the versatility and applicability of this approach, consolidating it as a valuable tool for environmental assessment and effective planning in the hydraulic fracturing industry.

“…However, methane is also a greenhouse gas, contributing to global warming. In view of the above regularities, it seems that the key global challenge is the need to construct an economic model that will allow for the sustainable use of methane (Brauers, 2022). One of the approaches to this goal is to develop technologies that allow for the effective capture and use of methane in energy processes.…”

A significant source of information regarding product quality for a company is the complaints lodged by customers. The analysis of complaints can provide the company with valuable insights. Therefore, the objective of this study is to analyze complaints from a one-month period within a company manufacturing baby strollers. The analysis of complaints was conducted to identify areas within the studied company where discrepancies occur, enabling appropriate corrective actions to be implemented. Design/methodology/approach: The Pareto chart was utilized to conduct the analysis of complaints, illustrating the group of most significant issues. To delve into the root cause of the problem, a task force team employed the 5 Whys method. In the article, based on conducted literature reviews, a theoretical description of quality management tools and methods such as the Pareto chart, the 5 Whys method, Kaizen philosophy, teamwork, and additionally, information regarding product quality and safety can be found. Findings: During the course of our work, the source of failures within the company was identified. The major issue turned out to be haste, affecting both the production staff and an external company collaborating with the enterprise. As part of the corrective actions, a motivational system was implemented for employees, and piecework norms were established within the company. Additionally, an innovative solution was applied in the examined enterprise through the design and creation of pattern books for inter-process control within the company and final inspection at the crossbar flat supplier. The proposed problem-solving methods within the enterprise can be applicable for future endeavors.Research limitations/implications: The study was conducted over a short period of time due to the urgent need to address existing issues within the company. It can be inferred that if a longer time frame were taken into account, it would be possible to identify additional causes of discrepancies. Originality/value: The obtained results can serve as a valuable source of information for other companies manufacturing baby strollers, which are seeking solutions to their own issues.

“…Natural gas is a vital source of energy which accounted for approximately a quarter of the global energy supply in 2020 [1]. However, its main component, methane, possesses a much higher greenhouse gas potential compared to that of CO 2 [2] and is responsible for around 20% of the rise in global temperature since the Industrial Revolution [3].…”

Various techniques were employed to prepare a dual support system of CeZrO2 and H-ZSM-5 (80) including physically mixing, co-precipitation and sonochemical methods, which were followed by the deposition of bimetallic Pd and Pt via wet impregnation to obtain the final catalysts. The catalysts were tested in the total methane oxidation between 200 and 500 °C and the most active is the material derived from sonochemical synthesis. This catalyst achieved a remarkable methane conversion of 84% at a low temperature of 300 °C and high Gas Hourly Space Velocity (GHSV) of 100000 ml g−1 h−1. Characterisation using x-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscope (SEM), scanning transmission electron microscope (STEM), Energy-dispersive x-ray spectroscopy (EDS), temperature-programmed reduction (TPR) and x-ray absorption fine structure (XAFS) techniques revealed the intimate distribution of catalyst components and facile redox behaviour of both Pd and CeZrO2 components. The catalysts based on sonochemical CeZrO2 was proven to be relatively stable with only 7% methane conversion loss after 50 h continuously on stream at 300 °C compared to the corresponding 14% witnessed with the commercial TiO2-based material.
