Their pioneering work significantly contributed to King Abdulaziz University being ranked No. 1 in the Arab World in 2019. The Times Higher Education World University Rankings highlighted the group’s innovative approaches and outstanding achievements, showcasing their impactful research on its website.
“KAU’s solid waste research group at the CEES is therefore trying to solve two problems at once by pioneering ways of turning waste into energy. The work harnesses the power of naturally abundant zeolites (minerals formed in volcanic rock and ash layers, and traditionally used in cement and building stones) in waste-to-energy technology applications, making them cost and energy effective. The group is also investigating the use of grass as a raw material for producing biofuels.”

greenhouse gas (GHG) emissions as well as water and soil contamination. The government considers reuse and recycling as optimum techniques for waste management following source reduction. However, the current waste recycling has been carried out mostly by informal sectors and only few recyclable materials such as paper, cardboard, metals and plastics are recycled (10-15% of total waste). The waste pickers or waste scavengers take the recyclables from the waste bins, containers and dumpsites. There is an immediate need to develop public-private partnership (PPP) to improve MSW management system in Makkah city including waste reuse and recycling. It is theoretically estimated that only by recycling glass, metals, aluminium and cardboard, climate will be saved from 5.6 thousand tons emission of methane
(CH4); a major source of GHG emissions and 140.1 thousand Mt.CO2 eq. of global warming potential (GWP) with carbon credit revenue of worth 67.6 million SAR. Similarly by recycling above-mentioned recyclables, a net revenue of 113 million SAR will be added to the national economy every year only from Makkah city. Moreover,
technically, the waste recycling does not require high-skill labour, complex technology and thus can be easily carried out in any urban areas like Makkah city.
and effective solution to waste management and energy issues is the emergence of waste biorefineries. These advanced systems not only provide sustainable waste management and energy solutions, but they also have the potential to reduce poverty and hunger while supporting global economic growth initiatives.
As our world faces critical environmental concerns, such as climate change and serious health issues, a major shift in our production and consumption paradigms seems inevitable. One solution to achieve that would be extending waste-oriented biorefineries, converting waste into energy, power, and useful products in a circular economy context. In light of the above, this Research Topic focuses on the role of waste biorefineries in meeting the SDGs, where respected scientists share their insights on waste biorefineries’ status, advancements, and prospects. Through their contributions, readers can explore how these innovative systems can play a vital role in achieving SDGs, tackling pressing environmental and health issues, and creating a better future. The accepted articles in this Research Topic are categorized under the sections of (1) Technological innovations and advancements in biorefineries, (2) Biomass sourcing, characterization, and valorization, and (3) Sustainable systems, economic growth, and policy implications based on the relevancy of their Research Topic and aims.
cost-effective and efficient biofuel production processes through the application of nanotechnology. The exceptional properties of nanomaterials (nanocatalysts) such as high surface area, catalytic
performance, crystallinity, durability, energy storage capacity, etc. offer great potential for optimizing biofuel production systems. Nanocatalysts could also serve recovery, reusability, and recycling purposes.
This Research Topic is designed to attract the state-of-the-art recent developments in fabrication, modification, and optimization of advanced nanocatalysts and nanostructured materials for biofuel production processes (Figure 1). This Frontiers Research Topic has attracted and compiled 12 top quality research and review articles. The articles have been written by researchers and academics working in institutions at different countries across the world including Australia, China, Egypt,
Greece, India, Iran, Malaysia, Netherlands, Pakistan, Saudi Arabia and South Korea. The editorial team of this research topic is very grateful to all the authors for their excellent contributions and making the research topic successful.
infrastructure and facilities to maintain efficient and practical global standards. As a consequence, the dump-sites or non-sanitary landfills have become the significant sources of greenhouse gases emissions, soil and water contamination, unpleasant odors, leachate, and disease spreading vectors, flies, and rodents. However, waste can be utilized to produce a range of potential products such as energy, fuels and value-added products under waste biorefineries.
A holistic and quantitative view, such as waste biorefinery, on waste management must be linked to the actual country, taking into account its socio-economic situation, local waste sources, and composition, as well as the available markets for the recovered energy and products. Therefore, it is critical to understand that solutions cannot be just copied from one region to the others. In fact, all waste handling, transportation, and treatment can represent a burden to the cities’ environment and macro and
micro economics, except for the benefits obtained from recovered materials and energy. Equally significant is a clear and quantitative understanding of the industrial, and public potential of utilizing recovered materials and energy in the markets as these can be reached without exacerbating the environmental issues using excessive transport.
The book explores new advancements and discoveries on the development of emerging waste-to-energy technologies, practical implementation, and lessons learned from sustainable waste management practices under waste biorefinery concept, which will accelerate the growth of circular economies in the world. The articles presented in this book have been written by expert researchers and academics working in institutions at different countries across the world including Germany,
Greece, Japan, South Korea, China, Saudi Arabia, Pakistan, Indonesia, Malaysia, Iran, and India. The research articles have been arranged into three main subject categories; 1) Resource recovery from waste, 2) Waste to energy technologies and 3) Waste biorefineries. This book will serve as an important resource for research students, academics, industry, policy makers, and government agencies working in the field of integrated waste management, energy and resource recovery, waste to energy technologies, waste biorefineries etc. The editorial team of this book is very grateful to all the authors for their excellent contributions and making the book
successful.
biogas is carried out by a complex microbial process in which an appropriate environment is necessary for the multiplication of microbes and their proper functioning. Biogas generated at low temperatures using psychrophilic enzymes has a low methane content; however, other factors such as pH, oxygen content, and salt concentration also affect microbial activities and hence the quality of the biogas. The electrical energy produced by biogas from agricultural waste feedstock
is carbon zero. In Asia, biogas production is the need of the time and will
not only contribute towards a low carbon economy but also will address the longstanding issue of deforestation and environmental pollution. If increasing energy demands of a growing population in Asia and Africa are addressed through this renewable approach, then it will enhance the energy security and environment integrity of these two continents.
produced from renewable resources including organic waste through biological processes. In the Kingdom of Saudi Arabia (KSA), the annual generation rate of municipal solid waste (MSW) is around 15 million tons
that average around 1.4 kg per capita per day. Similalry, a significant
amount of industrial and agricultural waste is generated every year in
KSA. Most of these wastes are disposed in landfills or dumpsites after
partial segregation and recycling and without material or energy recovery. This causes environmental pollution and release of greenhouse gas (GHG) emissions along with public health problems. Therefore, the scope of producing renewable H 2 energy from domestic and industrial waste sources is promising in KSA, as no waste-to-energy (WTE) facility exists. This chapter reviews the biological and chemical ways of H2 production from waste sources and availability of waste resources in KSA.
