One of the challenges in livestock production is significant volume manure generated, which must be appropriately managed to mitigate its environmental impacts. Untreated poses a potential hazard soil, surface water, groundwater, and human animal health. Based on life cycle assessment (LCA) method, research aims evaluate ecological load composted-pelletized poultry litter (CPPL) maize winter wheat production. Furthermore, loads CPPL applications are compared with those other N, P, K fertilizers. The study utilized openLCA software Agribalyse 3.1 database calculate eleven impact categories.

This research study presents a comparison of an in-person and online conference in terms environmental impact energy efficiency. The main goal our was to prepare complete life cycle assessment two-day (15-h), 200-participant based on different methods. Life assessments focus the numerical determination decarbonization consumption (lunch, dinner, food beverage during breaks), organization (discussions, correspondence, abstract booklet, registration package), travel, infrastructure. meals were examined by connecting stages preparation, cooking, end-of-life as cradle-to-grave analysis. We paid particular attention calculation consumption. After carbon footprint comparisons, areas with highest impacts pie diagrams identified. Lastly, SWOT chart SAP-LAP analysis diagram summarize achievable objectives challenges. In conclusion, there is no outstanding difference between methods for investigation. Travel contributes 57% overall at conferences, while holds second largest share, 8.41 kg CO2 equivalent/person/hour. Excluding calculated 0.362 equivalent/person/hour (only considering effect organization, administration package). Our initial hypothesis that reduces decarbonization, which results confirm.

Abstract One of the pressing issues any country faces is managing solid wastes. Traditionally, several methods have been used in past to manage increasing quantity waste. However, due increase population, urbanization, and various other reasons, there has steady growth The general public's cooperation vital understanding extent wastes, their generation, collection, transportation, disposal wastes safely. Urban local bodies also play a significant role waste as they are ones who can formulate plan per data available them. Infrastructure for another prime factor easy transportation disposal. There different conventional starting from landfills, incineration, etc., advanced methodologies. use incineration primary method now major source health hazards. present study reviews important practical management. review categorized into two sections: Conventional methodologies include thermal energy techniques, bioeconomy, anaerobic digestion valorization second section includes such green architecture, web-based geographic interface system, Internet Things (IoT), optimization artificial intelligence blockchain based management system. provides an overview technologies support system sustainable It discusses knowledge awareness be catered all sections people about

Published: June 22, 2023

In this study, the life cycle assessment (LCA) method has been used to evaluate environmental impacts of various municipal solid waste (MSW) management system scenarios in Banepa municipality, Nepal, terms global warming potential (GWP), acidification (AP), eutrophication (EP), human toxicity (HTP), abiotic depletion (ADP), and photochemical ozone creation (POCP). There are at least six possible MSW Banepa: current or baseline scenario (Scenario 1); composting with landfilling 2); material recovery facility (MRF) recycling, composting, 3); MRF anaerobic digestion (AD); 4); MRF, AD, 5); and, finally, incineration 6). Using both information from Ecoinvent 3.6 (2019) published research articles, a spreadsheet tool based on LCA approach was created. The impact recycling rate each abovementioned evaluated using sensitivity analysis, which showed that can considerably decrease life-cycle emissions system. Scenario 3 found have overall GWP 974.82 kg CO2 eq. per metric ton (t), EP 0.04 PO4 eq./t, AP 0.15 SO2 HTP 4.55 1,4 DB ADP −0.03 Sb POCP 0.06 C2H4 eq./t. By adoption biological treatments such as categories AP, EP, HTP, ADP, POCP, be significantly reduced. findings study potentially serve reference for cities developing world order aid planning operation environmentally friendly systems.
