Carbon footprint reduction associated with a surgical outreach clinic

Abstract Background: Healthcare services have large carbon footprints and can be used to minimize greenhouse gas emissions that can be reduced greenhouse gas emissions. Background: Healthcare services produce significant carbon footprints, which can be used to reduce greenhouse gas emissions. Outreach clinics may be able to aid in this reduction by improving patient-related travel. We also wanted to determine the carbon footprint savings associated with a head-and-neck surgery outreach clinic's head and neck surgery outreach clinic. Methods This was a cross-sectional analysis of patient travel habits to a surgical outreach clinic compared to a regional cancer treatment center from December 2019 to February 2020. The majority of patients traveled to the outreach clinic by using their own car. Both the median distance from the clinic and regional center was 29. 0 km and 327. 0 kilometers respectively. The mean carbon dioxide reduction per person was therefore 117,495. 4 g to 143,570. 9 g. Conclusions Compared to continuing care at a regional center, surgical outreach clinics reduce patient emissions associated with patient travel.

Carbon footprint based multi-objective supplier selection problem with uncertain parameters and fuzzy linguistic preferences

We have investigated supplier selection in this paper in terms of carbon footprints that are related to each supplier's activities. The proposed multi-objective supplier selection problem with uncertain value is solved with the help of a fuzzy concept-based goal programming model. The main goal of the proposed model is to deal with human subjectivity by using the linguistic preference-based approach and analyzing the organizational effects of supplier selection in terms of environmental sustainability. We've used Liu's Expected Constraint programming tool to convert the unpredictable parameters into a deterministic one.

A Standardized Method for Estimating the Carbon Footprint of Disposable Minimally Invasive Surgical Devices

In new benign prostatic hyperplasia MISDs, the authors of a standardized method for estimating the tangible carbon footprint of disposable minimally-invasive surgical solutions and their use in new benign prostatic hyperplasia MISDs. The determination of disposable surgical devices' CO2e emissions is essential to improving the healthcare supply chain. The proposed methodology relied on a partial product lifecycle analysis and was limited to a narrow portion of scope 3, which involved the manufacture of surgical device- and non-device-related items, including packaging and user manuals, and non-u2013device-associated products. The seven new disposable MISDs used worldwide for transurethral prostatic surgery were dismantled, and each piece was categorized, sorted into the correct raw material group, and weighed. Our results showed a wide variation in the estimated CO2 emissions of the most recent disposable MISDs for transurethral BPH surgery using this method.

Dynamic Analysis of Industrial Carbon Footprint and Carbon-Carrying Capacity of Zhejiang Province in China

This paper examines the carbon footprint, carbon footprint, carbon-carrying capacity, net carbon footprint, and carbon footprint of Zhejiang Province from 2015 to 2019. The carbon footprint of Zhejiang Province has achieved significant strides, according to the world average, although it does not indicate that the carbon reduction scheme has achieved great strides, but the per capita carbon footprint is much higher than the world average.

Carbon Footprint of Single-Use Plastic Items and Their Substitution

Plastic pollution reduction is a significant worldwide threat, and plastic reduction is a must-take to minimize plastic pollution. In addition, manufacturing, use, and disposal of plastic items also has a significant effect on the greenhouse effect, which can also be estimated in a life cycle framework by measuring their carbon footprint. In this work, a review of the carbon footprint evaluation of various single-use plastic categories has been done, establishing a method to clearly assess the benefits of switching to compostable and bio-plastic containers and materials in this case. The procedure was tested and validated through a case study, where a plastic reduction scheme was introduced and implemented, and the CO 2 equivalent reduction was determined, revealing a reduction compared to a substitute made of equal or other materials equal to 73% and 90%, respectively.

The Impact of the Aggregate Used on the Possibility of Reducing the Carbon Footprint in Pavement Concrete

The goal of this study was to minimize the carbon footprint by using several forms of aggregates that are used for concrete intended for road building. After 150 cycles of freezing and thawing, the permeability of concrete, the frost resistance in salt, and the pore structure in hardened concrete were determined in order to determine concrete's stability. The flexural strength of all series exceeded 5. 5 MPa, and the highest tensile strength results were obtained for a composition based on dolomite aggregate. Besides the reduction of the carbon footprint by 32% thanks to the use of CEM III cement rather than CEM I, as a result of the report, the usage of local aggregates located 80 kilometers away from the construction site reduced the carbon footprint by another 19. 2%.

Carbon Footprint of Away-From-Home Food Consumption in Brazilian Diet

The aim of this report is to see if AFHF consumption is related to environmental sustainability. Carbon footprint coefficients were used to determine carbon footprint coefficients from 20,780 adults from 24 h recalls from the 2017–2013 Brazilian National Dietary Survey. The mean carbon footprint from foods that were not consumed away from home made up 18% of the total carbon footprint. In conclusion, food intake away from home in Brazil's urban areas was associated with atmospheric greenhouse gas emissions regardless of age and wealth. To improve individual and planet health, away-from-home food intake can be considered.

Life Cycle Assessment-Based Carbon Footprint Accounting Model and Analysis for Integrated Energy Stations in China

China has invested heavily in energy infrastructure to achieve its carbon neutrality target, and the new integrated energy stations projects will provide significant opportunities. The procedure is used on a 110 kV wind power IES project in China to investigate and quantify lifecycle carbon dioxide emissions, identify the key influence factors of carbon footprints, and make carbon reduction recommendations. The results can help identify key influence factors and make recommendations for carbon reduction for the construction of IES projects.

Carbon Footprint Assessment of Hydrogen and Steel

The state of the art is determined for current hydrogen production with a focus on hydrogen carbon footprints using the life cycle assessment tool. Direct reduction plants with integrated electric arc furnaces enable steel production, which is almost entirely dependent on hydrogen and electricity, or rather on electricity alone, if hydrogen derives from electrolysis. Hence, an integrated steel site has a demand for 4. 9 kWh of electric energy per kilogram of steel per kilogram. Steel in 2040 was 0. 75 kilograms CO 2 eq/kg steel considering a European sustainable development scenario concerning the electricity mix, with a European sustainable development scenario concerning the electricity mix.

Carbon Footprint for Post-Mining Soils: The Dynamic of Net CO 2 Fluxes and SOC Sequestration at Different Soil Remediation Stages under Reforestation

We investigated the dynamic of C stock in two different post-mining regions, i. e. , the limestone post-mining soil remediated with embankment, and the lignite post-mining soil remediated with sewage sludge. At different remediation methods, the purpose of the investigation was to determine the C sequestration in sewage sludge amended and non-amended post-mining soils. SOCs increased as a result of the soil remediation age, owing to the remediation of the S2's remediation. For both soils, we saw a negative CO 2 leak from the soil under remediation, and the net CO 2 emissions rate has decreased after one year. After 1 year, we saw an increase in nutrient content and a decrease in heavy metals content. Such a positive correlation between the remediation of post-mining soils and C sequestration points to a step toward climate change mitigation.
