This paper examines the environmental impacts of climbing ropes using life cycle assessment (LCA). An online survey was conducted to evaluate users’ behaviour and potential an open loop recycling project for old ropes. The results LCA study show that production base material, polyamide 6, has, at 50%, highest impact on total global warming 46.6 kg CO2-eq. per rope most other issues. At present,...

waste is a by-product of our daily activities, which poses a serious threat to societies all over the world. in this study, life cycle assessment (lca) methodology was used to determine municipal solid waste (msw) management strategy for minna, niger state, nigeria. three scenarios were modelled as alternatives to the current waste management system in minna. the baseline scenario was the exist...

this paper presents the results obtained from the life cycle assessment (lca) of the productionof sicilian artichokes (cynara scolymus) with the aim of reducing impacts, interpreting the results, suggesting possible improvements and enriching the sustainability knowledge already existing in the agro food field. artichokes represent one of the excellent italian agricultural products even if stil...

transportation is an important part of modern community life as well as one of the largest sources of greenhouse gas emissions in urban communities, the population growth of which can increase transportation capacity. monorail systems are relatively new rail transportation systems which are currently being designed and constructed in different countries. we have applied the intergovernmental pa...

background: human echinostomiasis is an intestinal disease caused by the members of family echinostomatidae parasites. the aim of present research was to identify echinos­tomatidae cercariae emitted by lymnaea palustris snails from mazandaran province in the north of iran based on the morphological and morphometrical charac­teristics of the different stages of experimental parasite life cycle. ...

Impacts to groundwater from anthropogenic sources have resulted in numerous occurrences of subsurface contamination plumes. The management of these plumes has resulted in the expenditure of billions of dollars worldwide. The protection of human health and the environment is the primary emphasis driving plume management. Various methods have been proposed to optimize the response action to the p...

in this article, modeling and optimization of power consumption of two–stage compressed airsystem has been investigated. to do so, the two – stage compressed air cycle with intercooler offajr petroleum company was considered. this cycle includes two centrifugal compressors, ashell, and a tube intercooler. for modeling of power consumption, actual compressors isentropicefficiencies and intercool...

A model is developed to minimize the life cycle cost of a system providing availability of services from a constellation of satellites. The model consists of a cost model, and a performance model. The cost model includes the cost of purchasing and maintaining an inventory of satellites and launch vehicles, launch operations, and on orbit operations. The performance model evaluates the availabil...

the supercapacitive behavior of polyaniline/mno2-carbon black (pani/mno2-cb), mno2-cb nanocompositesand cb was studied. mno2-cb made by the in situ direct coating method to deposit mno2 onto cb; then pani coating was coated on it. morphology of the nanocomposite was studied by x-ray diffraction (xrd), fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the el...
