[CEST2019_00838] Contribution to the exploitation of oil by-products for use in the production of quality feed through the fermentation with the fungal strain LGAM P123 of basidiomyces Pleurotus ostreatus
by Karalis J., Αrapogloy D., Chorianopoylos N., Iliopoylos C.

In Greece, large quantities of by-products are produced annually from urban and industrial activities among them very high olive oil production by-products. Thus, the interest of the scientific community has focused on the utilization of olive oil waste mainly as a feed using various microorganisms and fungi, of which only a small number can biodegrade the waste.

[CEST2019_00858] The possibility of recycling of multilayer packaging waste: Reducing Environmental impacts
by Mumladze T., Šleiniūtė A., Denafas G.

Multilayer Packaging Waste (MPW) represents the largest fraction of packaging waste and is mainly composed of multiple plastic films laminated with Al foil (Ec.europa.eu. (2018). Packaging waste statistics). The most produced multilayer film is based on the different polymers, such as polyester (PET), polypropylene (PP), and polyethylene (PE) as main components, and an aluminum layer (European Commission JRC Technical reports). According to Eurostat Statistics Explained, the amount of packaging waste generated in the EU between 2007 and 2016 was estimated at 79 ± 1.25 million ton per year.

[CEST2019_00882] Determining a Probability of the uncontrolled landfills emergence in Georgia's Rural Areas Using Integrated Methodology
by Buachidze N., Dvalishvili N.

In this work, with the support of the local municipality, we’ve collected for each highland region the data showing: the number of population, existence of the main sources causing waste, the quantity of the dumpster, the frequency of the waste removal with the relevant technic etc. Based on all these data by applying our methodology, we count a probability of existence of the uncontrolled landfills that can exist in the particular region. We also use the pictures from a drone.

[CEST2019_00821] Development of Porous Carbon Nanomaterials from Petroleum Waste for CO2 Capture and Mineralization
by Jalilov A.,Albaiz A., Alsaidan M.

Development of in situ preparation method of porous low-density carbon materials from industrial waste is important. Alkali earth metal doped porous carbon materials can serve as a support for CO2 mineralization in pores to generate the final carbonate enriched porous carbons, MCO3-PC, as a composite for potential applications in CO2 capture and sequestration. Herein we report on developing mineral carbonization technology using porous carbons from vacuum residue to generate products that are best suited economically for CO2 sequestration.

[CEST2019_00775] Co-Pyrolysis of Plastic Wastes: Effects of Temperature and Feedstock Ratio on Chemical Composition of Liquid Product
by Özçakir G., Karaduman A.

Co-Pyrolysis of Low Density Polyethylene (LDPE) and Polystyrene (PS) was carried out in a semi-batch glass reactor system. Effects of temperature and feedstock ratio on pyrolytic product yields (gaseous, liquid and solid residue) and chemical composition of the liquid were investigated. All experiments were performed with 15 g feedstock in 25 mL/min nitrogen atmosphere and 60 min duration at specified temperature. Temperature was changed from 470 to 620 °C with 50 °C break by utilizing PID controller which was setted 10 °C/min heating rate.

[CEST2019_00750] Pyrolysis of Waste Plastic Laminates and Coconut Husk: Optimization of Fuel Oil Yield, Higher Heating Value and Energy Value
by Olalo J., Reyes J., Rollon A.

Alongside increasing use of single-use plastics, especially in developing countries is increasing mismanaged solid wastes. There is great need for economically viable processes such as pyrolysis that can convert waste to energy resource. Coconut husk, which is also an abundant waste in tropical countries is a good material for co-pyrolysis with single-use plastic, as both have high energy content. Thus, this study determines the potential of plastic laminates and coconut husk pyrolysis as feedstock for production of pyrolystic oil.

[CEST2019_00521] A novel types of compound for surface treatment of carbon nanotubes for more effective application in polymers
by Hangyási K., Varga Cs., Nagy R., Simon-Stőger L.

Nowadays, beneficial management of plastic and rubber waste from different sources and environmentally friendly ways of recycling is becoming an increasing challenge. A possible solution for that problem could be to produce plastic composites usually consisting of heterogeneous phases. That fact and the interface between phases, and characteristics of components all play important roles in development of properties of end-product. By using a compatibilizing additive a chemical bridge can be created between the plastic composite components requiring reactive functional groups.

[CEST2019_00526] Remarkable role of experimental olefin-maleic-anhydride copolymer based compatibilizing additives in PET bottle recycling
by Nagy B., Varga Cs.

Over the past 50 years demand for plastics drastically increased worldwide resulting in plastic wastes causing serious environmental problems. The main market sector of european plastics industry is the packaging industry most of which is polyolefins and poly(ethythylene-terephtalate). Polymer blends based on waste resources can solve the issues of recycling. We have studied rheological and tensile properties of three types of PET/engineering thermoplastic blends (PET/PC, PET/PA and PET/ABS) produced with different processing techniques.

[CEST2019_00536] Biorecovery of metal sulfides from leachates obtained through zinc-carbon battery recycling
by Retka J., Uhrynowski W., Yang Z., Karczewska-Golec J., Bajda T., Debiec-Andrzejewska K., Drewniak L.

One of the most commonly used methods of recycling of spent zinc-carbon (alkaline) batteries is hydrometallurgical leaching with sulfuric acid. The technology is highly efficient and enables the recovery of the majority of deposited metals. Unfortunately, it also generates highly acidic wastewaters containing significant amounts of sulfates and metal ions, which have typically been considered off-balance material.
The aim of the study was to develop

[CEST2019_00498] A simple and flexible flowsheet process for efficient and selective metal recycling from spent fluid cracking catalysts
by Sadeghi S.M., Jesus J., Pinto E., Almeida A., Soares H.

This paper investigates the recovery of the main metals (La and Al) present in a spent fluid cracking catalyst (FCC) through the hydrometallurgical processes of leaching and selective precipitation. Complete La leaching (99±1)% was achieved under microwave-assisted leaching with the use of 1 M HCl and a liquid-solid (L/S) ratio of 5 for 90 s. Since the main impurity presented in the leachate was Al, an initial process was developed to selectively recover Al by alkaline precipitation.
