An Aspen plus process simulation model for exploring the feasibility and profitability of pyrolysis process for plastic waste management.

Plastics, integral to various human activities, have led to a surge in production, posing substantial challenges in waste management. The persistent non-biodegradability of plastics, taking over a century to decompose, necessitates exploration into technologies for their conversion into sustainable fuels. Pyrolysis, an oxygen-free thermal decomposition process, emerges as a promising avenue for producing liquid fuels from plastic waste.

Hydrodynamic performance assessment of photocatalytic reactor with baffles and roughness in the flow path: A modelling approach with experimental validation.

Purification of wastewater is essential for human being as well as for the flora and fauna, and sustainable environment. Photocatalytic reactor with TiO coated layer can be used to degrade the pollutants but without proper pollutant mass transfer in the reactive surface, photocatalytic reactor decreases its effectiveness. The baffles and rough surface in the flow path can improve the fluid mixing to enhance pollutant mass transfer to improve the reactor's performance.

End-of-life tyre conversion to energy: A review on pyrolysis and activated carbon production processes and their challenges.

The number of end-of-life waste tyres has increased enormously worldwide, which is one of the non-biodegradable Municipal Solid Waste (MSW) piling up in an open space for a long time. Every year, various types of tyres are released in the environment from different vehicles, such as trucks, buses, cars, motorcycles, and bicycles, which negatively impact the environment. Nowadays, waste tyres are treated in several ways, whereas thermochemical conversion is one of them, including combustion, gasification, incineration, and pyrolysis.

Advancements in algal membrane bioreactors: Overcoming obstacles and harnessing potential for eliminating hazardous pollutants from wastewater.

This paper offers a comprehensive analysis of algal-based membrane bioreactors (AMBRs) and their potential for removing hazardous and toxic contaminants from wastewater. Through an identification of contaminant types and sources, as well as an explanation of AMBR operating principles, this study sheds light on the promising capabilities of AMBRs in eliminating pollutants like nitrogen, phosphorus, and organic matter, while generating valuable biomass and energy. However, challenges and limitations, such as the need for process optimization and the risk of algal-bacterial imbalance, have been identified.

Waste plastics pyrolytic oil is a source of diesel fuel: A recent review on diesel engine performance, emissions, and combustion characteristics.

Most waste plastics can be converted into automobile fuel through the pyrolysis process. Plastic pyrolysis oil (PPO) has a heating value comparable with commercial diesel. The properties of PPOs depend on parameters such the plastic and pyrolysis reactor types, temperature, reaction time, heating rate, etc.
