AB  - The aim of this paper is to investigate the application of modified lignin-based adsorbent for
successful removal of dichromate ions and sodium diclofenac (DCF) from aqueous solutions by
adsorption. Modification of lignin-based adsorbent (LBA) was performed by inverse suspension
copolymerization with branched poly (ethylene-imine) using epichlorohydrin as a crosslinker. After
that, the functionalization of LBA was performed by chemical binding of amino modified nanoparticles
of manganese (IV) oxide, in order to improve the adsorption properties. Characterization of
LBA-MnO2 microspheres was performed using FT-IR spectrometer, Scanning electron microscopy,
BET/BJH analysis. The adsorption process was performed in a batch adsorption system. The results
were obtained with the help of kinetic and corresponding equilibrium adsorption isotherms. The
maximum adsorption capacity for the removal of Cr2O7
2- ions and DCF was obtained using the
Langmuir model and amounts to 88.4 mg g-1 and 52.8 mg g-1 at 45 °C, respectively. Adsorption
kinetics was described using a second-order pseudo model. Based on thermodynamic parameters, it
was concluded that the adsorption process is an endothermic and spontaneous. Based on the obtained
results, LBA-MnO2 material possess very good adsorption properties.

AB  - Management of waste polymers (polyethylene - PE and polypropylene - PP) represents one of the major
obstacles in the field of environmental protection, which demands a most efficient and eco-friendly
technological solution. Due to the high use of various plastic materials, the amount of landfilled or
dissipated plastic waste is continuously growing. Therefore, this paper examines the possibilities of
recycling these polymers, alongside obtaining granules of similar or advanced physico-mechanical
characteristics to the commercially available ones. The applied technology consists of several
consecutive processes (collecting, grinding, washing and extruding) where the obtained materials can
later be incorporated into widely applicable products, such as foils, bin liners, bags, among others. In
this way, high-quality products with great market potential are obtained, which will consequently
contribute to lower extraction and less depletion of natural resources. Thus major problems may be
solved optimally, consolidating the efficiency of improved eco-friendly technologies which is in line with
environmental protection and sustainable waste management.

AB  - During a fire, passive fire protection systems are designed to prevent the spread of flames, smoke, and toxic gases. The new fire-retardant (FR) material, used for passive fire protection, is created by combining copolymers (VC-co-VAc) (Slovinyl KV 173) and PVC K70 with expanded graphite and plasticizers/modifiers such as diisononyl phthalate - DINP, diisononyl terephthalate - DINTP, dioctyl adipate - DOA, as well as plasticizers that are synthesized based on tertiary recycling of waste poly(ethylene terephthalate) (PET), 1-hexadecene, azodicarbonamide (ADC), tri(p-cresyl phosphate), epoxidized soybean oil (ESO) and acrylate emulsion (DH50, Ecrylic, or Flexryl, etc.). The obtained material's morphology was examined using an emission scanning electron microscope (FESEM) field. Tensile testing was used to determine the mechanical properties of the obtained samples, as well as Shore A hardness and toughness using the Charpy impact test. All samples obtained were tested according to non-flammability standards. To conform to the new trend of "green economy," the development of novel eco-friendly FRs with improved thermal and mechanical properties will include careful consideration of environmental protection and sustainable development.
