Abstract
Based on the necessity of evaluating composite packaging wastes from both environmental and economic perspectives, it aimed to obtain carbon nanotube (CNT) from the pyrolysis gas product of this material by the catalytic chemical vapor deposition method (CCVD) via an upcycling approach. In the first stage, composite packaging wastes were pyrolyzed. Secondly, the composition of the gas via gas chromatography was determined. In the third stage, CNT production studies were carried out by the CCVD method in a tubular reactor at four different temperatures between 600 and 900 °C with nickel catalyst. The effects of temperature and carbon source feeding ratio on the properties of the obtained CNTs were investigated. CNTs produced in this study were compared with a commercial product. As a result, high-quality multi-walled carbon nanotube of 20–30 nm diameter and in micrometer scale length comparable to commercial products were produced from the gaseous product at 800 °C under Ni-catalysis.
期刊介绍：
Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
