Green logistics (GL) is the main development trend of modern logistics. an inherent condition and a basic system circular economy (CE). Circular means as realization closed loop material flows in economic system. concept which links between resources products, products consumers. helpful for closing economy. important tool The first section article explains term green second part paper presents relationship logistics, using practice practices on example sludge management.

The bioconcentration factors and the translocation index have been determined for assessment of level phytoextraction in plants. bioaccumulation factor, as quotient content a given metal plant to its soil, defines ability accumulate heavy metals. index, Ti, is measure capacity This provides useful means quantitative description relative differences biological availability metals paper presents results studies on effect fertilizing soil translocate cadmium, zinc, lead, nickel from roots, then...

The water and sewage sector is responsible for approximately 3.5% of energy consumption in the European Union (EU). Leaks causing losses distribution systems (WDSs) are 24% EU, which contributes to additional emissions greenhouse gases (GHGs). implementation Directive Parliament EU Council on quality drinking (Directive (EU) 2020/2184) introduces obligation report by large utilities Member States. reported indicator will be infrastructure leakage index (ILI) ratio between current annual real...

The aim of the work was to evaluate possibility using commercial and modified activated carbons for removal oxytetracycline from aqueous solutions. kinetics statics adsorption as well effect carbon dose solution pH on efficiency were analyzed. Based study isotherms, ranked in following order: F-300 > WG-12 Picabiol ROW08 WACC 8 × 30 F-100 WAZ 0.6–2.4. most effective characterized by large specific surfaces. best matching results obtained for: Redlich–Peterson, Thot Jovanovic models, lower...

The purpose of this article is to analyze and compare the benefits barriers implementation Environmental Management Systems (EMS)—International Standard ISO 14001 Eco-Management Audit Scheme (EMAS)—by organizations. This paper attempts answer following research questions: 1. Does either or EMAS bring same organizations? 2. system functioning duration in company influence internal external resulting from EMS implementation? 3. Are economic aspects adoption as important for entrepreneurs...

AbstractAdsorption of Cd(II) and Ni(II) ions on the modified activated carbon (WG-12) was measured. Two methods modification, i.e. a traditional method in rotary furnace developed by author reactor that uses Joule's heat, were analysed. The effects performed modification evaluated based surface area, water vapour adsorption, volume micro-, meso- macropores, number oxygen groupings measured with Boehm method. application these two resulted increase adsorption Ni2+ Cd2+. most favourable...

The presented research investigated the removal of chloramphenicol from water solutions on selected activated carbon available in three grades with different porous structure and surface chemical composition. Two models adsorption kinetics were examined, i.e. pseudo-first order pseudo-second models. For all examined cases, results tests higher value coefficient R2 described by equation for kinetics. was also carbons modified ozone. measurements taken pH values 2 7. Chloramphenicol most...

Companies using water distribution systems to reduce the operating costs and increase reliability of supply systems, as well protect disposable resources, must search for ways losses. The article points out economic environmental aspects possibilities international loss assessment standards have been analysed. reflections presented in paper refer current trends world field management. presents results analysis losses network operated by Water Supply Sewerage Company Gliwice (Przedsiębiorstwo...

The article presents the results of studies on effects fertilization with (1) sewage sludge, (2) compost produced from mixture sludge and forestry waste (3) green Dano technology bioaccumulation heavy metals in Miscanthus giganteus biomass. were obtained pot experiment semi-natural conditions during period April 2007 to November 2010. testing concerning third year (the plant crop 2010). soil used for cultivation M. was sampled area close vicinity steel works. mineral fertilizers...

The possibility of using activated carbon for the removal salicylic acid andiibuprofen sodium has been explored. These compounds are observed in crude and treated sewage surface water. effect pH on adsorption efficiency was assessed. Tests were carried out from solutions with ranging 2 to 10 (salicylic acid) 6 (iibuprofen sodium). It found that higher pH, lower tested. Salicylic most efficiently adsorbed a solution = 2, which it occurred mainly an undissociated form. achieved pH=2 91%, while...

Abstract The article presents the results of life cycle assessment different scenarios biomass use to produce energy in a selected company. study is made on case Lesaffre Polska S.A. and its facility Wolczyn which one most modern plants Central Europe. company leaders using environmental criteria strategic decision-making. Its goal avoid any waste form own circular business system. One recent investments fired steam boiler that uses agricultural woody energy. Previously, was sold power plant...
