Abstract:

Changes in the agricultural management and climatic changes within the past 25 years have had a serious impact on soil organic matter content and contribute to different carbon storage in the soil. Prediction of soil carbon pool, validation, and quantification of different models is important for sustainable agriculture in the future and for this purpose a long-term monitoring data set is required. RothC-26.3 model was applied for carbon stock simulation within two different climatic scenarios (hot-dry with rapid temperature increasing and warm-dry with less rapid temperature increasing). Ten years experimental data set have been received from conventional and organic farming of experimental plots of Mendel University School Enterprise (locality Vatín, Czech-Moravian Highland). Average annual temperature in this area is 6.9°C, average annual precipitation 621 mm, and altitude 530 m above sea level. Soil was classified as Eutric Cambisol, sandy loam textured, with middle organic carbon content. Its cumulative potential was assessed as high. Results showed linear correlation between carbon stock and climatic scenario, and mostly temperature and type of soil management has influenced carbon stock. In spite of lower organic carbon inputs under organic farming this was less depending on climatic changes. Conventional farming showed higher carbon stock during decades 2000–2100 because of higher carbon input. Besides conventional farming was more affected by temperature.

Abstract:

Carbon dioxide CO2 is a component of air that is responsible for the growing global warning and greenhouse gases emissions. The energy sector is one of the main sources of CO2 emissions in the world and especially in Ukraine. Carbon capture, utilization and storage (CCUS) is a group of technologies that play a significant role along with renewable energy sources, bioenergy and hydrogen to reduce CO2 emissions and to achieve international climate goals. Nowadays there are thirty-five commercial CCUS facilities under operation around the world with a CO2 capture capacity up to 45 million tons annually. Tougher climate targets and increased investment provide new incentives for CCUS technologies to be applied more widely. CCUS are applications in which CO2 is captured from anthropogenic sources (power generation and industrial processes) and stored in deep geological formations without entering atmosphere or used in various products using technologies without chemical modification or with conversion. The article discusses the use of various technologies of CO2 capture (post-combustion capture, pre-combustion capture and oxy-combustion capture), CO2 separation methods and their application in the global energy transition to reduce the carbon capacity of energy systems. Technical and economic indicators of CO2 capture at different efficiencies for coal and gas power plants are given. Technologies of transportation and storage of captured carbon dioxide and their economic indicators are considered. The directions for the alternative uses of captured CO2, among which the main ones are the production of synthetic fuels, various chemicals and building materials, are also presented and described in the paper. The possibility of utilization captured СО2 in the production of synthetic fuel in combination with Power-to-Gas technologies was studied. Keywords: greenhouse gases emissions, fossil fuels, СО2 capture technologies, capture efficiency, synthetic fuel

Abstract:

The oxidized ordered mesoporous carbons of cubic and hexagonal structure obtained by two templating methods (soft and hard) were applied for the first time as delivery systems for paracetamol—the most common antipyretic and analgesic drug in the world. The process of carbon oxidation was performed using an acidic ammonium persulfate solution at 60 °C for 6 h. The functionalization was found to reduce the specific surface area and pore volume of carbon materials, but it also led to an increasing number of acidic oxygen-containing functional groups. The most important element and the novelty of the presented study was the evaluation of adsorption and release ability of carbon carriers towards paracetamol. It was revealed that the sorption capacity and the drug release rate were mainly affected by the materials’ textural parameters and the total amount of surface functional groups, notably different in pristine and oxidized samples. The adsorption of paracetamol on the surface of ordered mesoporous carbons occurred according to different mechanisms: donor–acceptor complexes and hydrogen bond formation. The adsorption kinetics was assessed using pseudo-first- and pseudo-second-order models. The regression results indicated that the adsorption kinetics was more accurately represented by the pseudo-second-order model. Paracetamol was adsorbed onto the carbon materials studied following the Langmuir type isotherm. The presence of oxygen-containing functional groups on the surface of ordered mesoporous carbons enhanced the amount of paracetamol adsorbed and its release rate. The optimal drug loading capacity and expected release pattern exhibited oxidized ordered mesoporous carbon with a hexagonal structure obtained by the hard template method.

Abstract:

AbstractIn the early stages of systems development, Systems Engineers will typically evaluate alternatives based on performance, cost, risk, and schedule to evaluate the solution space of alternatives. While these criteria have proven to be successful, there is growing interest in the analysis of carbon costs as well to contribute to the decision making. These decision criteria are very good to help the decision maker select the best alternative within the solution space in which to develop a system concept. We offer another criterion for consideration in order to account for carbon expenditure throughout the SE lifecycle. We believe that including this dimension can influence decision makers to evaluate a richer portion of the solution space. This approach is developed and exercised with a notional example.

<strong>Abstract</strong><strong>—</strong> Cropping system is an effective agricultural practice which play crucial role in soil carbon stabilization, soil health and fertility as well as in sequestering atmospheric CO<sub>2 </sub>in soil for long period of time. With these considerations in mind, a research was conducted in the Prayagraj district of eastern Uttar Pradesh to evaluate how major agricultural systems affect soil carbon stock. The major cropping system includes Wheat-Wheat, Mustard- Mustard, Rice-Wheat and Rice-Mustard Soil samples were collected from eight tehsil of Prayagraj district randomly from depth 0-15 cm and 15-30 cm depth. The findings show that soil organic carbon store in rice-wheat cropping systems is higher than in other cropping systems.

Full text

Abstract:

Plants are key components of the terrestrial ecosystem carbon cycle. Atmospheric CO2 is assimilated through photosynthesis and stored in plant biomass and in the soil. The use of turfgrass is expanding due to the increasing human population and urbanization. In this review, we summarize recent carbon sequestration research in turfgrass and compare turfgrass systems to other plant systems. The soil organic carbon (SOC) stored in turfgrass systems is comparable to that in other natural and agricultural systems. Turfgrass systems are generally carbon-neutral or carbon sinks, with the exception of intensively managed areas, such as golf course greens and athletic fields. Turfgrass used in other areas, such as golf course fairways and roughs, parks, and home lawns, has the potential to contribute to carbon sequestration if proper management practices are implemented. High management inputs can increase the biomass productivity of turfgrass but do not guarantee higher SOC compared to low management inputs. Additionally, choosing the appropriate turfgrass species that are well adapted to the local climate and tolerant to stresses can maximize CO2 assimilation and biomass productivity, although other factors, such as soil respiration, can considerably affect SOC. Future research is needed to document the complete carbon footprint, as well as to identify best management practices and appropriate turfgrass species to enhance carbon sequestration in turfgrass systems.

Full text

Abstract:

In this paper commercially available activated WD-extra carbon (Gryfskand) which is applied for water treatment was used. Activated carbon was modified by the following chemical agents: H2O2, HNO3 and HCl. Chemical modifications significantly affect the chemical, structural and surface properties of activated carbons. Hydrophobization with ethereal stearic acid was performed on the raw material and samples after chemical modification. Hydrophobic properties of the samples were specified. The relationship of the chemical modification agents with hydrophobization degree was indicated. The thermal effects of wetting by methanol was measured. The heat of wetting was calculated. The purpose of the work was to modify the WD carbon properties to obtain an adsorbent for cooling systems characterized by both good thermal capacity and moisture resistance. The modifying chemical substances applied accounted for an increase in the concentration of the acid functional groups. The hydrophobized and HCl-modified WD(HCl) carbon has the best hydrophobized properties. The results of studies describing such modifications allow to conclude that the use of hydrophobic materials may lead to the production of sorbents with new functions facilitating their storage and use.

Full text

Abstract:

The use of certification systems in agriculture mitigates greenhouse gas (GHG) emissions and promotes sustainable low-carbon practices. Their implementation contributes to the rational use of resources and results in the development of a human-centric economy that prioritizes people’s actual needs towards sustainable economic growth. Some low-carbon certification systems for agricultural products have been developed in European Union (EU) countries and elsewhere; however, their reliability in assessing agricultural emissions at the farm level and the anticipated benefits are not yet adequately justified. This review paper presents and discusses the most important existing certification systems, namely, Solagro, Label bas Carbone/LCL, LEAF Marque Standard, and Wineries for Climate Protection, the one being developed in the frame of the ClimaMED LIFE project, and the one developed almost 10 years ago in the Republic of Korea. The structure of these systems and their benefits and challenges are discussed. More emphasis is given to the EU certification schemes and the impact they may have towards meeting the targets of the Green Deal, which aims to reduce GHG emissions at least 55% by 2030 compared to 1990 levels and make Europe climate neutral by 2050.

Abstract:

Silvopastoral systems (SS) combine productivity with climate change mitigation and improve carbon (C) stocks. The objective of the research was to estimate C stocks in three silvopastoral systems of the high jungle. Three silvopastoral systems were selected for the study: Cedrelinga cateniformis (Tornillo), Eucalyptus spp. (Eucalyptus) and Inga edulis (Inga). Soil samples of 0-15 cm and 15-30 cm were collected and analyzed to determine their physical and chemical characteristics. The estimation of C reserves was carried out from biomass with allometric equations. Statistical analysis was performed using descriptive analysis (means and standard deviation) and ANOVA and use of the Scott Knott test. Soil properties did not show significant differences between SS, except for P, Al and CEC. Carbon reserves were higher in the screw system and lower in the inga system. In general, C reserves in the SS were greater in the soil and represented the main C reserve, surpassing the vegetation. The results highlight the importance of soil as a carbon sink and its role in mitigating climate change.

Abstract:

The aim of this research was to determine the effect the ozonation and sonification processes for post-treatment of coke wastewaters using activated carbons. The tests were carried out in three systems ie. I-AC (activated carbon), II-O3+AC (ozonation + activated carbon) and III-US+AC (ultrasound + activated carbon). In the experiment were used a three types of activated carbons: WG-12, ROW 08 Supra and Picabiol. The sorption process was carried out in static conditions at contact for 24h time of the wastewater with activated carbons. Coke wastewater was oxidized through ozonation at a constant ozone dose of 10 mg/dm3. Sonication of coke wastewater was conducted at vibration amplitude was 61.5 μm, with sonication time of 8 min. Results of removing of COD were estimated on the base of sorption capacity and COD removal efficiency. The second system was the most effective (O3+AC) for carbons WG-12 and ROW 08 Supra, whereas in the case of carbon Picabiol, the best efficiency was found for system I (AC). The lowest efficiency of removal of COD from coke wastewater was the systems III (US+AC) for all three activated carbons.

Abstract:

Helium is a finite global resource, which is becoming vitally important to recover and reuse as it continually diminishes. The helium recovery process uses plant machinery that can consume significant amounts of power and generate a large carbon footprint. Many organizations around the world are actively trying to reduce their carbon footprint and, therefore, lessen the impact of their operations on the climate. Here we have assessed the CO2 produced per litre of liquid helium, when processed by the ISIS helium recovery system, and compared it with the estimated carbon footprint of liquid helium that is supplied by the gas companies. The comparison clearly demonstrates that the carbon footprint of liquid helium from the recovery system is significantly smaller than that of liquid helium supplied by the gas companies.

Abstract <strong>Objectives:</strong> To analyze and justify the significance of yard management and green technology investments for both production and distribution processes in the supply chain along with effects of carbon taxes. <strong>Methods:</strong> A non-linear sustainable supply chain model considering carbon emissions during manufacturing, distribution, storage of inventory, idling during a delivery, idling and unnecessary wandering at a facility is formulated with an incorporation of yard management systems investments along with the effects of carbon taxes. Green technology investment is also incorporated to optimize total cost of systems. Lagrangian method is used to obtain the optimal solution of the problem. <strong>Findings:</strong> The proposed model has been solved with the prescribed method and it gives the total integrated supply chain model cost with yard management systems investment is $108,220.650 and the total integrated supply chain model cost without yard management systems investment is $112,520.340. This shows that the model with yard management systems performs better than the other one. <strong>Novelty:</strong> Yard management systems and green technology investment have been incorporated in a supply chain simultaneously, along with carbon taxes whereas earlier research has predominantly emphasized solely on green technology investments. 2020 Mathematics Subject Classification: 90B05, 90B06. <strong>Keywords:</strong> Logistics, Yard Management System, Carbon emission, Carbon taxes, Green Technology

Abstract:

Carbon footprint is widely accepted as an indicator of greenhouse gas emissions and global warming. Modeling carbon footprints based on life cycle assessment is applied as a way to evaluate the net contribution of greenhouse gases to the atmosphere from orchard production systems over one growing year. This net balance approach considers the sources and sinks of carbon and therefore provides a better reflection of an orchard system's net contribution to climate change. Carbon footprinting of organic kiwifruit and apple production systems in New Zealand indicated that the studied systems had a net sequestration from 2.4 to 5 t of CO2e/ha/year and therefore can be potentially considered as carbon sinks under the Kyoto Protocol. This finding implies that the organic kiwifruit and apple orchardist can gain a monetary benefit by earning carbon credits. However, further research to improve and validate this approach is essential before it can be practically used for decision-making at the orchard level and for policymaking at the national level.

Abstract:

In integrated energy system modeling, extant research predominantly addresses single-energy system optimization or carbon emission flow models, failing to adequately elucidate the mechanisms of combined energy and carbon flow modeling in complex energy systems. This deficiency hampers a thorough analysis of the coupling relationships between energy and carbon flows, thereby posing significant challenges for resource allocation and carbon mitigation within integrated energy systems. This paper presents an innovative energy–carbon coupling model, constructing a unified framework for energy and carbon flow modeling centered on the energy hub, thereby overcoming the limitations of traditional approaches that are unable to model both energy and carbon flows concurrently. The model comprehensively examines the coupling nodes and carbon density correlations among energy conversion devices within multi-energy systems, precisely quantifying carbon emission paths and distribution across devices. This provides a novel methodology for carbon emission management in integrated energy systems. Case studies on typical integrated energy systems demonstrate the proposed model’s efficacy in low-carbon economic dispatch. The energy–carbon coupling model developed in this study offers a high-adaptability solution for integrated energy systems in multi-energy, low-carbon parks, achieving an optimal balance between economic efficiency and environmental performance under dual objectives of energy demand and carbon emission minimization.

Abstract:

Carbon Footprint (CFP) refers to the emission of all greenhouse gases (GHGs) during a given period by any activity or entity. The standard unit for measuring it is the carbon dioxide equivalent (CO2eq), such that the impact of each GHG is expressed in terms of the amount of CO2 that would create the same amount of warming. It is widely recognized that the 2020 global value for average per capita CFP (estimated as 4.47 Mg CO2eq) is not sustainable and that it must be reduced to < 2Mg CO2eq if global warming is to be limited to 20C. Recent estimates show that 31% of human-caused GHG emissions originate from the world’s agri-food systems, the major sources being deforestation, livestock production (from enteric fermentation and manure), food waste disposal, and fossil fuel use (by farms and the food-retail sector). Land application of chemicals such as fertilizers, weedicides, and insecticides is the most significant factor in the AFOLU (agriculture, forestry, and other land-use) sector. Enhancement of the natural process of terrestrial C sequestration in soil and vegetation is a widely recognized approach to reducing the AFOLU sector CFP. The adoption of multispecies agroforestry systems with nitrogen-fixing trees is a promising strategy for accomplishing this goal. Another is integrated silvopastoral systems that combine animal production with deep-rooted grass and trees that could counteract the GHG emission through enteric fermentation in animals with enhanced soil C sequestration.
