This paper explores the environmental impact of super-linear growth trends for AI from a holistic perspective, spanning Data, Algorithms, and System Hardware. We characterize carbon footprint computing by examining model development cycle across industry-scale machine learning use cases and, at same time, considering life system hardware. Taking step further, we capture operational manufacturing present an end-to-end analysis what how hardware-software design at-scale optimization can help...
Abstract Energy conservation in brick production is crucial to achieving net-zero carbon emissions from the building sector, especially countries with major expansions built environment. However, widely disparate energy consumption estimates impede benchmarking its importance relative steel and cement industries. Here we modelled Indian regional by combining a nationwide questionnaire survey on feedstock, process variables practices remote sensing data kiln enumeration. We found large...
Abstract Understanding the climate impact of residential emissions starts with determining fuel consumption various household activities. While cooking have been widely studied, non-cooking energy-consumption activities in sector such as heating and lighting, overlooked owing to unavailability data at national levels. The present study uses from Carbonaceous Aerosol Emissions, Source Apportionment Climate Impacts (COALESCE) project, which consists surveys over 6000 households across 49...
Abstract Estimation of aerosol radiative forcing continues to suffer from large uncertainties, partially a lack observations optical properties. Limited measurements the atmospheric imaginary refractive index (iRI) have been made, especially in some world's most polluted regions. In this study, we measured and micro‐physical properties at regional site, Rohtak, India, representative cities Indo‐Gangetic plains northern India. The average PM 2.5 during campaign was 163 μg/m 3 with...
Emission measurements from agricultural residue burning in India reveal strongly absorbing aerosol emissions with warming potentials larger than those previously estimated.
The incorporation of waste plastic materials such as polystyrene (PS) in asphalt pavement has shown promise to improve its durability and simultaneously help alleviate the environmental problems caused by sources. But addition these introduces issues poor mixability phase separation during paving process. Studies have that inclusion various reactive polymeric additives cross-linking agents may issues. aim present work is examine feasibility using trans-polyoctenamer sulphur based modifiers...
The use of amine-based additives is common practice to improve the stripping resistance and performance properties bituminous mixtures. This study concerned with synthesis derived from waste Polyethylene Terephthalate (PET), investigation its effect as an effective modifier for bitumen. Firstly, two amine functionalised namely bis(2-hydroxyethyl) terephthalamide (BHETA) bis(2-aminoethyl) (BAET) were chemically synthesised using aminolysis process PET. effects BAET BHETA on bitumen mixture...
Abstract. In South Asia, biomass is burned for energy and waste disposal, producing brown carbon (BrC) aerosols whose climatic impacts are highly uncertain. To assess these impacts, a real-world understanding of BrC's physio-optical properties essential. For this region, the order-of-magnitude variability in spectral refractive index as function particle volatility distribution poorly understood. This leads to oversimplified model parameterization subsequent uncertainty regional radiative...
Abstract Emission sources influencing high particulate air pollution levels and related mortality in India have been studied earlier on country‐wide sub‐national scales. Here, we use novel data sets of emissions (for 2019) observations created under the Carbonaceous Aerosol Emissions, Source Apportionment, Climate Impacts network (Venkataraman et al., 2020, https://doi.org/10.1175/bams‐d‐19‐0030.1 ) WRF‐Chem simulations to evaluate drivers PM 2.5 during episodes airsheds with different...

Abstract Renewable energy befits as an attractive and sustainable solution to compensate for the imbalance in supply demand of fossil fuels. Continuous depletion fuels, price variations detrimental effect greenhouse gas emissions are burning issues current scenario. Non-edible vegetable oil can be considered a comparable alternative replace conventional diesel fuel. There some operational with straight oils (SVOs) such their less calorific value, higher density viscosity etc. which may dealt...
In the present day situation, toxicity in municipal solid waste has increased to a very high level leading various problems. The main purpose of study is improve quality mixed by adding locally available biomass. It was observed that feedstock for refuse derived fuel and biomethanation contains 12% 20% toxicity, respectively, as result degrading energy potential waste. By wheat soya bean husk having calorific values 4,100 kcal/kg 4,170 not only reduced but content respective also enhanced

Fired clay brick kiln (FCBK) industry is one of the unorganized and often overlooked sectors in terms its regional air quality health impacts. Approximately 87% 1.5 trillion bricks produced worldwide annually are made Asia. These typically fired small-scale traditional kilns that burn coal or biomass without pollution controls. Clamp most technology manufacturing. It a batch-style produces 10,000-200,000 per batch time period two to four weeks. uses as primary firewood rice husk...
