Sustainable Approaches for Biofuels from Waste Materials
The global concerns for energy security have increased immensely due to the rapid depletion of fossil fuel-based energy sources, rapid population growth, and urbanization. Worldwide, sustainable development goals are being achieved for global warming and climate change mitigation with minimizing greenhouse gas emissions. These consequences have led to the sustainable utilization of waste materials for biofuel production. The utilization of waste materials as a biofuel feedstock is an innovative approach towards resolving various global issues related to sustainable waste management, greenhouse gas emissions, and dependency on fossil fuel energy. Biofuel refers to various renewable fuels, including biomethane, biohydrogen, bioethanol, biobutanol, biodiesel, bio-lubricants, and bio-jet fuels. Over the years, biofuels have been produced from different waste materials, including municipal waste, sewage sludge, livestock waste, discarded animal fats, waste cooking oil, lignocellulosic biomass, animal manure, food waste, and agricultural waste residue. However, sustainable approaches to biofuel production from waste materials necessitates state-of-the-art technologies and legislative policies for waste collection and storage. To ensure the environmental and economic viability of biofuels from waste materials, it is crucial to understand the spatial and temporal availability of waste materials, waste characteristics, waste valorization methods, and available technologies. This Topic invites manuscripts focusing on biofuel production from waste materials. The editorial team welcomes researchers, academics, industry leaders, and stakeholders to submit their original research articles, review articles, and case studies dealing with (but not limited to) the following research topics:
- State-of-the-art technologies for biofuel production from waste materials.
- Waste material collection, segregation, and transportation strategies for biofuel production.
- Waste material characteristics and pre-treatment technologies in biofuel production.
- Potentials and differences of waste materials for biofuel production.
- Integrated sustainable waste management scenarios for biofuel production.
Life cycle assessment, environmental impact assessment, and economic viability analyses geared towards biofuel production from waste materials.
