The accumulation of plastic wastes in landfills and the environment threatens our public health, while leading to loss potential carbon resources. urgent necessary lies developing an energy-saving environmentally benign approach upgrade into value-added chemicals. Artificial photosynthesis holds ability realize upcycling by using endless solar energy under mild conditions, but remains initial s...

Plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. People’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. This study aims to determine community’s perception of usage and disposal of plastic bags in Eastern Ethiopia. A quantitative cross-sectional study has been condu...

Fast pyrolysis of five post-consumer plastic waste materials was studied using coupled with gas chromatography/mass spectrometry (Py-GC/MS) technique. Prescription medicine bottles, landfill liners, and one type industrial represented polyolefin-based polymers, whereas packaging material polystyrene, other polyurethane. The noncatalytic catalytic degradation mechanisms all wastes were elucidate...

The need for an automated sorting system cannot be overemphasized due to the growing needs for high throughput and accuracy. Manual sorting method may achieve good accuracy, but at the expense of throughput. This study formulates an automated plastic wastes identification model to overcome the limitation of the manual sorting method. The proposed identification model employed singleton Sugeno f...
