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...

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...

Workshop ini berisikan mengenai bagaimana cara melakukan penilaian dampak lingkungan, yang dihasilkan oleh sebuah produk di sepanjang proses produksinya. Penilaian lingkungan dilakukan menggunakan metode life cycle analysis (LCA) dengan bantuan software Simapro. Peserta dari workshop yaitu para pengusaha IKM dan masyarakat umum. Saat ini, pelaku usaha belum banyak menyadari timbul dikonsumsi ma...

The forestry sector in Portugal faces important challenges, resulting an increased incidence of fires and the action pathogens, which puts sustainability forest resources at risk. Due to economic, social, environmental importance forests, this work assessed land use impact maritime pine eucalypt standing Portuguese forests. SimaPro software was used translate inventory table results into catego...

Today, an important part of paved surfaces in the world uses asphalt mixtures. This practice increases use aggregates and fossil fuels, availability which is limited. Most studies referring to mixtures reported compared mechanical performances without detailing environmental impacts different technologies proposed. The objective this study was present compare through a life cycle assessment usi...

Food production involves both agricultural and industrial activities which consume several resources among which: water, energy, land, minerals chemicals. The efficiency in the use of depends on type food is produced adopted processes. In any case if discarded or lost at step supply chain this represents a waste energy resources. For reason, LIFE project irexfo, coordinated by University Perugi...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

Globally, as the population and living standards expanded, so did use of energy materials. Renewable resources are being used to help address issue reduce greenhouse gas emissions (GHG). Because lignocellulosic biomass widely available renewable, various processes convert these into bioenergy. In current study, two production were evaluated, namely transformation vine shoot waste value-added bi...
