As an alternative to the traditional process based on the use of sulfides, an unhairing process in drum by hydrogen peroxide, named DEPOXO, was developed for the production of high-quality bovine upper leather. A preliminary investigation at laboratory scale has allowed to set out the optimal process conditions, in terms of H2O2 dosage (9 %) and pH (12.5), in order to achieve an effective unhai...

This life cycle assessment (LCA) evaluates and quantifies the environmental impacts of the production of hydrogen and transportation fuels from the fast pyrolysis and upgrading of corn stover. Input data for this analysis come from Aspen Plus modeling, a GREET model database and a U.S Life Cycle Inventory Database. SimaPro 7.3 software is employed to estimate the environmental impacts. The resu...

Carbonization is a newly developed process that converts sewage sludge to biocoal, a type of solid biomass that can partially substitute for coal during power generation. This study presents an assessment of the environmental effects of various sewage sludge treatment processes, including carbonization, direct landfills, co-incineration with municipal solid waste, and mono-incineration in Taiwa...

The construction industry plays a significant role in contributing to various environmental impacts, including climate change, acidification, and ecotoxicity, among others. This research paper presents scientific analysis focused on the evaluation of masonry residential house by life cycle assessment (LCA) methodology. Specifically, it investigates impacts associated with production phase mater...

Abstract A circular economy (CE) is considered capable of being a solution to reduce the use natural resources and waste without harm. system uses products materials at maximum value function. Various strategies were developed for this purpose. However, these efforts often require additional energy create more valuable products. Does increase in value-creation mean than consumption make it happ...

Fuel cell electric vehicles are a promising solution for reducing the environmental impacts of automotive sector; however, there still some key points to address in finding most efficient and less impactful implementation this technology. In work, three electrical architectures fuel were modeled compared terms their manufacturing use phases. The differ number position DC/DC converters connectin...

The study aimed to evaluate the waste impact on environment in fresh milk production activities from dairy cows rearing farms distribution process of a processing factory and selling agents, identify most significant potential for contamination environment, provide alternative improvements based environmental caused by activities. This research was conducted farmer cooperative which is an organ...

The management of solid waste is currently seen as one the most important concerns that national authorities, particularly in south Europe, must address. In recent years, emphasis has begun to be paid Construction and Demolition Waste (CDW) being largest stream European Union produced by renovation repair work on buildings, roads, bridges, other constructions made bulky materials such asphalt, ...

A systematic literature review was conducted to investigate the environmental impact of solar thermal power plants in industrial supply chains. number different collectors like parabolic trough (PT), linear Fresnel (LFR), dish (SD) and towers (ST) were considered analysed. The first observation that PT generate lowest level Green House Gas (GHG) emissions, followed by LFR, DT SD plants. There a...

The objective of this study is to quantify the climate- and environmental impact venison production from six wild life species in Denmark: Red deer, roe fallow boar, mallard pheasant, compare it with commercially produced beef, pork chicken Denmark. method for quantifying applied original LCI data obtained complete cycle Danish all species, supplemented Ecoinvent® LCAFOOD on materials processes...
