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

Co-Pyrolysis of Corn Stover with Plastic: Optimization Based on Synergy

(Corresponding) Salvilla J., Rollon A., De Luna M.
Topic: 
Environmental biotechnology and bioenergy
The co-pyrolysis of lignocellulosic wastes such as Corn stover with plastic has been found to improve the both the yield and quality of pyrolysis oil and gas products. In this study, the co-pyrolysis of Corn stover (CS) with plastic (LDPE, and PP) were studied through thermogravimetric analysis...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

Evidence of marine plastic particles transfer to the atmosphere through bubble bursting.

Masry M., (Corresponding) Rossignol S., Temime Roussel B., R'mili B., Bussière P., Bourgogne D., Wong-Wah-Chung P.
Topic: 
Emerging pollutants
Plastic debris in the marine environment are the subject of an extensive literature. According to studies dedicated to the determination of plastic litter abundance, models were used to estimate the global plastic debris abundance and to simulate their transfer and distribution. Despite these...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

Detection of Microplastics using Laser-Induced Breakdown Spectroscopy - A first approach

(Corresponding) Sommer C., Schneider L., Nguyen J., Prume J., Lautze K., Koch M.
Topic: 
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The worldwide inability to enforce effective plastic guidelines results in an increasing accumulation of microplastics in natural habitats. Since this problem is in need of human intervention, we propose Laser-Induced Breakdown Spectroscopy (LIBS) as a new tool to identify microplastics. Our...Read more
