In the production of solid recovered fuel (SRF), certain waste components have excessive influence on the quality of product. The proportion of rubber, plastic (hard) and certain textiles was found to be critical as to the elemental quality of SRF. The mass flow of rubber, plastic (hard) and textiles (to certain extent, especially synthetic textile) components from input waste stream into the o...
One environmental problem in most countries is the huge quantities of plastic waste, which has different types polymers such as polyethylene terephthalate (PET), polypropylene (PP)., These plastics become a because their non-biodegradability, toxicity, etc. The recovery waste pavements an ecological technique that contributes to preservation natural resources. In this study, PET was used additi...
Replacing conventional plastics with bioplastics, i.e., that are bioderived and/or biodegradable, does not necessarily solve the issues of resource depletion and plastic waste accumulation. To come to a truly sustainable economy, growing bioplastics production must be paralleled effective end-of-life strategies for bioplastic waste, which is essential all regardless their biodegradability. Whil...
Plastics have become indispensable in our daily lives, but plastic waste has proliferated landfills and oceans since most plastics are non-biodegradable cannot be mechanically recycled. Existing chemical recycling processes such as pyrolysis hydrogenolysis typically use high temperatures, generate unnecessary greenhouse gas emissions, often require expensive noble metals, show limited generalit...
Gasification of plastic waste is an emerging technology particular interest to the scientific world given production a hydrogen-rich gas from material. Devolatilization first step thermochemical decomposition process which crucial in determining quality whole gasification process. The devolatilization polypropylene (a key compound waste) has been investigated experimentally bench-scale fluidize...
Background and Objectives: In recent years, poor industrial waste managements have created many crises in human societies. The aim of this study was to investigate industrial waste management located between Tehran and Karaj zone in 2009-2010.Materials and Methods: This study is descriptive and sectional which was done by site visits, (Iranian environmental protection organization) use of que...
This study analysed the dissolution phenomena of plastic polymers into biodiesel through experimental measurement. The effects of experimental parameters, such as temperature, concentration, agitation, time and feed rate, etc, when mixing two different polymers with biodiesel wereobserved to deduce trends that can be adapted into further exploration. Suchinvestigation is reasonably new in Austr...
