Recycling of Polyurethanes Containing Flame-Retardants and Polymer Waste Transformed into Flame-Retarded Polyurethanes
PublikacjaThe growing number of polyurethanes (PUs) produced every year has developed methods for their mechanical and chemical recycling which yield valuable products like substitutes for commercial polyols or flame-retardants. PUs can be produced in different shapes and forms (i.e., elastomers, flexible or rigid foams, coatings, etc.) using several different components (i.e., di- or polyisocyanates, ester- or ether-based polyols, low-molecular...

Preparation and characterization of monometallic (Au) and bimetallic (Ag/Au) modified-titania photocatalysts activated by visible light
PublikacjaThe Au-TiO2 and Ag/Au-TiO2 nanoparticles have been prepared using a water-in-oil microemulsion system of water/AOT/cyclohexane and water/Triton X-100/cyclohexane. The obtained photocatalysts were subsequently characterized by a BET method, DRS spectroscopy, X-ray photoelectron emission spectroscopy (XPS), scanning transmission electron microscopy (STEM) and X-ray powder diffraction analysis (XRD). For gold-doped titanium (IV) oxide...

Chapter 21. Investigation on sorption of 1-methyl-3-octylimidazolium chloride on sewage sludge in wastewater treatment
PublikacjaNiniejsza publikacja stanowi opis zjawiska sorpcji chlorku 1-metylo-3-oktylo imidazolu w wysuszonym osadzie czynnym pochodzącym z oczyszczalni ścieków. Uzyskana w toku badań izoterma sorpcji potwierdza wielowarstwową adsorpcję długołańcuchowych cieczy jonowych. Stosunkowo wysoki współczynnik podziału KD wynika z pH w jakim prowadzony był eksperyment oraz wysokiej zawartości węgla organicznego w sorbencie (50,49%) i potwierdza,...

Speciation of heavy metals in stabilized sewage sludge according to innovative technology with reed basins application in Denmark
PublikacjaObecność metali ciężkich w komunalnych osadach ściekowych, obok innych zanieczyszczeń toksycznych i skażeń mikrobiologicznych, stanowi podstawowe kryterium oceny ich przydatności do przyrodniczego wykorzystania. Większość światowych uregulowań prawnych dotyczących dopuszczalnych stężeń metali ciężkich odnosi się do ich całkowitych stężeń. Jednak w celu określenia zachowania metali ciężkich w środowisku przyrodniczym należy oznaczyć...

Efficiency of landfill leachate treatment in a MBR/UF system combined with NF, with a special focus on phthalates and bisphenol A removal
PublikacjaIn this study, a pilot-scale membrane bioreactor (MBR) was operated at a municipal solid waste plant (MSWP) to treat a mixture of landfill leachates (LLs) obtained from modern (MP-LLs) and previous (PP-LLs) waste cells. The MBR unit combined anoxic and aerobic zones with external ultra- and nanofiltration (MBR/UF and MBR/UF/NF, respectively). In addition to the removal of macropollutants, special attention was given to phthalates...

Odour Perception Using a Sniffing Team at a Municipal Solid Waste Treatment Plant: A Case Study
PublikacjaThe monitoring of odour intensity, generated by a landfill area, is a difficult activity since it is a multi-source problem with discontinuous odour emissions. A modified sniffing team method is described here and applied to determine the main odour sources in a landfill located in Pomerania, Poland. Four consecutive test sessions were performed during the following months: August, December, April, and June. It was found that the...

An experimental assessment on a diesel engine powered by blends of waste-plastic-derived pyrolysis oil with diesel
PublikacjaThe utilization of plastic solid wastes for sustainable energy production is a crucial aspect of the circular economy. This study focuses on pyrolysis as an effective method to convert this feedstock into renewable drop-in fuel. To achieve this, it is essential to have a comprehensive understanding of feedstock composition, pyrolysis process parameters, and the physicochemical characteristics of the resulting fuel, all correlated...

Assessment of the devulcanization process of EPDM waste from roofing systems by combined thermomechanical/microwave procedures
PublikacjaEthylene-propylene-diene rubber (EPDM) is a elastomer widely used in common industrial applications. EPDM can be shaped into sheets and employed as isolating material for roofing systems. In this study, scraps of EPDM from commercial, industrial and residential roofing systems were treated by combined thermo-mechanical and microwave devulcanization processes including peroxide of benzoyl (BPO). The devulcanized EPDM (Dev-EPDM)...
