Pyrolysis of Waste Plastic Laminates and Coconut Husk: Optimization of Fuel Oil Yield, Higher Heating Value and Energy Value
(Corresponding) Olalo J., Rollon A., Reyes J.
Topic:
Solid waste management
Operating parameters such as percentage composition, process temperature, and particle size affects the outcome of the co-pyrolysis of coconut husk and plastic laminates. Highest yield of 31.17% occurred at 600oC, 5cm particle size and 32% of coconut husk. The corresponding energy value was 1.89688...Read more
Co-Pyrolysis of Plastic Wastes: Effects of Temperature and Feedstock Ratio on Chemical Composition of Liquid Product
(Corresponding) Özçakır G., Karaduman A.
Topic:
Solid waste management
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...Read more

The possibility of recycling of multilayer packaging waste: Reducing Environmental impacts
(Corresponding) Mumladze T., ŠLEINIŪTĖ A., Denafas G.
Topic:
Solid waste management
Multilayer Packaging Waste (MPW) represents the largest fraction of packaging waste and is mainly composed of multiple plastic films laminated with Al foil. Most produced multilayer film is based on the different polymers, such as: polyester (PET), polypropylene (PP), and polyethylene (PE) as main...Read more
Preparation of carbon nanotubes from plastic solid wastes over magnetic nickel ferrite catalysts
Lopes J., Roman F., Santos Silva A., (Corresponding) Diaz de Tuesta J., Lenzi G., (Corresponding) Silva A., (Corresponding) Faria J., Gomes H.
Topic:
Solid waste management
This work presents the development of magnetic carbon nanotubes (MCNTs) from plastic solid waste (PSW). For this purpose, diverse catalytic nanoparticles based on Fe, Ni and Al were prepared by impregnation of alumina or co-precipitation of Ni, Fe and Al nitrate salts with NH4OH, followed by...Read more

An overview of the plastic waste and recycling status in Qatar
(Corresponding) Hahladakis (Chachladakis) J.
Topic:
Solid waste management
The State of Qatar has recently launched its national vision (QNV2030) underlining, therein, its full commitment to retain harmony between the main three pillars of sustainable development: economic growth, social development and environmental management. However, rapid development and "mega...Read more
