“…Synthetic gas consisting mostly of CO and H2 is the feedstock for many catalytic synthesis systems. [595][596] The synthetic gas mixture can be catalytically converted to methanol and other alcohols. Platform chemicals such as ethylene, propylene, and other alkenes can be produced via the methanol-to-olefins prcoess.…”

Less than 10% of the plastics generated globally are recycled, while the rest are incinerated, accumulated in landfills, or leach into the environment. New technologies are emerging to chemically recycle waste plastics that are receiving tremendous interest from academia and industry. Chemists and chemical engineers need to understand the fundamentals of these technologies to design improved systems for chemical recycling and upcycling of waste plastics. In this paper, we review the entire life cycle of plastics and options for the management of plastic waste to address barriers to industrial chemical recycling and further provide perceptions on possible opportunities with such materials. Knowledge and insights to enhance plastic recycling beyond its current scale are provided. Outstanding research problems and where researchers in the field should focus their efforts in the future are also discussed.

“…A full review on methanation catalysts advancements for SNG production could be found in (Gao et al, 2015). The most common reactor type used in the methanation process is the fixed bed reactor due to its simple and effective design, although several other designs such as the fluidized bed reactor, honeycomb reactor, and microchannel reactor were also considered due to better catalyst exposure (Bolt et al, 2020).…”

“…Another pathway for SNG production is the electrochemical pathway where the electricity generated from renewables was used to produce H 2 via electrolysis, followed by methanation to produce SNG. Comprehensive reviews on SNG production methods could be found elsewhere (Kopyscinski et al, 2010;Fendt et al, 2016;Bolt et al, 2020).…”

Energy security and sustainability are undeniably the main concerns in combatting climate change. While an immediate call for all-green and renewable energy seems to be impossible due to huge financial implications and inadequate supporting energy structure, an alternative to fossil fuels needs to be established. Natural gas, a naturally occurring fossil gas is a cleaner energy source option compared to other fossil fuels such as coal, bitumen, and diesel. Natural gas makes the best fit for a sustainable renewable energy transition in any country around the globe due to its competitiveness towards other fossil fuels such as coal and its ability to aid the integration of renewables. This review highlights the technological pathways of utilizing natural gas in a transition to sustainable renewable energy systems, with a focus on the natural gas components and resources point of view for ASEAN member states (AMS). Policies that support the development of natural gas as a key alternative energy source in sustainable renewable energy transition would also be reviewed. This review aims to provide a thorough guide to researchers, stakeholders, and policymakers to construct and support efficient, reliable, affordable, sustainable, and environmentally friendly energy systems utilizing the abundant inexpensive natural gas.
