AB  - Production of organic dyes has been constantly increasing in the last decades, hence their us-age leaves a huge environmental impact usually on aquatic biota. Wastewaters carrying dissolved dyes are toxic to all organisms existing in water, therefore such wastewater streams have to be ap-propriately treated before they can be released into the environment. Development of effective ad-sorbents, which can be used in wastewater treatment, is mandatory. Another concern in the produc-tion of sorbing materials is the formation of spent acids or bases since they are commonly used for the activation of adsorbents. Spent acid liquor produced during the activation of expanded vermicu-lite (EVer) is utilized as the start material for the preparation of layered double hydroxide (LDH-EVer) by the method of co-precipitation process at low supersaturation. The prepared adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy with X-ray energy dispersive spectroscopy (SEM-EDS). Fabricated material is utilized as an adsor-bent of methyl orange dye from aqueous solutions. During the experiments, contact time were varied and thus the rate of adsorption is determined. The obtained results show a high adsorption capacity of 63 mg g-1.

AB  - Due to the increasing use and widespread of plastics, poly (ethylene terephthalate) (PET) and poly
(vinyl chloride) (PVC) are becoming one of the major threats to the environment. The aim of this
paper is obtaining plasticizers from recycled PET, and hot/cold mixing thereof with PVC to produce
new materials. Plasticizer was obtained from PET using ethylene glycol (EG) in the presence of
catalyst FASCAT 4100, followed by treatment with maleic anhydride and finally 2-ethylhexanol
(2-EtHex). The obtained glycolysate and plasticizer, individually or mixtures thereof, were used for
the production of polygranulates based on waste PVC in order to obtain an expanded mass of
homogenized PVC with glycolysate/plasticizer. The abovementioned procedures and test results for
the regranulates and products indicate that the proposed technology offers a solution to the problem
of waste PET and PVC through transesterification in order to obtain plasticizer based on PET and
EG, called 2-EtHex/MA/РG/PET/EG/MA/2-EtHex used in the processing of PVC waste and in
regranulate. The obtained regranulates are further processed by injection molding or extrusion into
commercial products such as slippers, footwear, boots, garden hoses, mats, floor mats, etc.
