“…The results are in line with the study conducted by Thahir et al 49 They investigated the pyrolysis of waste polypropylene (PP) in the range of temperature from 500°C to 650°C using ZSM-5 catalyst. They also reported that the increase in reaction temperature also accelerates the breaking of polymer bonds, and then undergoes a hydrogen chain transfer reaction between molecules thus, it results in more liquid than gas.…”

The main objective of this study is to enhance the valuable octane booster aromatics benzene, toluene, and ethylbenzene (BTE) and reduction of styrene in the fuel oil obtained from the pyrolysis of equally mixed waste expanded polystyrene (WEPS) and waste high density polyethylene (WHDPE). This research article, demonstrated the pyrolysis of equally mixed (50 wt.%:50 wt.%) waste expanded polystyrene (WEPS) and waste high-density polyethylene (WHDPE) followed by in situ-hydrogenation and aromatization in a small laboratory scale reactor for the production of value added commodity and gasoline octane boosters mainly benzene, toluene, and ethylbenzene (BTE). Three reactor arrangements i.e., liquid phase/L-type, vapour phase/V-type, and multiphase/M-type were used for conducting the catalytic pyrolysis of feedstock using ZSM-5, ammonium powder as a catalyst. The maximum liquid yield of 87.41 wt.% was obtained for thermal pyrolysis at a temperature of 650°C and at a heating rate of 15°C/min. Whereas, the maximum liquid yield of 82.65 wt.% was obtained for liquid phase/L-type catalytic pyrolysis at a temperature of 600°C, and at a heating rate of 15°C/min. On the other side, vapour phase/V-type and multiphase/M-type catalytic pyrolysis produced a maximum liquid yield of 78.62 wt.% and 74.07 wt.%, respectively at a reaction temperature of 550°C and at the same heating rate. The pyrolysis oil obtained from thermal pyrolysis contained lowest BTE content of 10.43 wt.% and highest styrene content of 66.25 wt.%. Whereas, the highest BTE content of 30.16 wt.% and lowest styrene content of 53.32 wt.% was found in pyrolysis oil obtained from multiphase/M-type catalytic pyrolysis. The quantitative measurement of BTE and styrene content in the pyrolysis oil was made by the gas chromatography (GC) in a flame ionization detector (FID) mode.

“…The composition of the feed stock also has a great effect on the product (Miandad et al, 2019;Mibei et al, 2023). Pyrolysis tends to require a lot of energy, therefore the use of a catalyst helps to reduce the temperature required, increase the rate of reaction, and ultimately reducing the long chain in products from the pyrolysis process, thereby reducing its boiling point (Thahir et al, 2021;Mibei et al, 2023). In recent times.…”

Plastics have become a modern-day nuisance to the environment and man due to improper management at their end-of-life. The structure and additives in fossil-based plastics make them non-biodegradable and, therefore, can persist in the environment for hundreds of years. Since a small percentage of plastic waste is recycled annually (9%) most of this plastic waste is being managed by open-air incineration or disposal in landfills where these additives can easily contaminate the air, soil, and water apart from the fact that a lot of these plastic waste find their way into our water bodies resulting to a lot of harm to the Eco-system. Recycling of plastic is an effective means of tackling the menace of plastic pollution, with chemical recycling as the most effective recycling process as it completely removes the waste plastic from the environment. Manufacturing and use of bioplastics like Polylactic acid, a good substitute for fossil-based polymer polyethylene terephthalate (PET), is a welcome development with the People’s Republic of China championing in the production. Legislative tools have been enacted in countries across the globe banning the use and manufacturing of single-use plastic bags. The implementation of this legislative move has been effective in some countries like the People’s Republic of China, Morocco, and Rwanda. Nigeria enacted the Plastic prohibition bill banning the manufacturing, use, and importation of all plastic bags in May 2019. This ban does not affect the behavioral and plastic management system in Nigeria as plastic bags are still used in cities across the country, littered in waterways and landfills. Therefore, there is a need to review the bill to include waste generation and management. Emphasis should also be placed on the production, and use of cost-effective bioplastic polymers and products

Design of Zr- and Al-Doped *BEA-Type Zeolite to Boost LDPE Cracking

Nowadays, the increase in plastic waste is causing serious environmental problems. Catalytic cracking has been considered a promising candidate to solve these problems. Catalytic cracking has emerged as an attractive process that can produce valuable products from plastic wastes. Solid acid catalysts such as zeolites decompose the plastic waste at a lower temperature. The lower decomposition temperature may be desirable for practical use. Herein, we synthesized both Zr- and Al-incorporated Beta zeolite using amorphous ZrO 2 –SiO 2 . The optimized Zr content in the dry gel allowed the enhancement of Lewis acidity without a significant loss of Brønsted acidity. The enhancement of Lewis acidity was mainly due to Zr species incorporated into the zeolite framework. Thanks to the enhanced Lewis acidity without any significant loss of Brønsted acidity, higher polymer decomposition efficiency was achieved than a conventional Beta zeolite.
