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

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

Valorisation of polyolefins into magnetic carbon nanotubes: application as catalysts in wet peroxide oxidation of paracetamol
Sanches L., (Corresponding) dos Santos Silva A., Fontana Roman F., Diaz de Tuesta Triviño J., Alves da Silva F., Gomes H.
Topic:
Advanced oxidation processes
This work deals with the application of magnetic carbon nanotubes (MCNTs) in the catalytic wet peroxide oxidation (CWPO) of paracetamol (PCM), a pharmaceutical compound selected as model contaminant of emerging concern (CEC). MCNTs were synthetized by catalytic chemical vapor deposition (CCVD) at...Read more
Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol
(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.
Topic:
Advanced oxidation processes
Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...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
UTILIZATION OF AGRICULTURAL AND URBAN PLASTIC WASTE REVIEW: INTRODUCTION TO PYROLISIS AND HYDROCARBON REFORMATION
KOUMPAKIS D., (Corresponding) VLACHOKOSTAS C.
Topic:
Waste-to-energy
Agricultural and urban waste consist of large quantities of biomass and petroleum originated waste. These two categories are rich in hydrocarbons which can be utilized again after their first life cycle. Pyrolysis is a thermochemical process in which solid hydrocarbons decompose in conditions of...Read more

Plastic waste utilization: Challenges and opportunities for waste-to-energy in Baguio City, Philippines
(Corresponding) Duran J., Victoriano J., Lunag Jr. M., Diccion Jr. A., Putiyon P., Solijon J.
Topic:
Waste-to-energy
Amounts of residual wastes, such as plastics, paper, and textiles, in urban areas have drastically increased over the years, which hence requires sustainable waste management schemes. Refuse derived fuel (RDF) provides a solution in addressing minimizing waste disposal in landfills and providing...Read more
