Biomass is the largest material based renewable energy source in the world, including forest and agriculture residues, yard clippings, and wood chips. In addition, tremendous wastes, mainly comprising wasted biomass, are being generated during fast urbanization and population growth, for example, municipal solid waste (MSW) and animal manure. Bioenergy recovery from biomass and wastes is a desirable way for their high-value utilization, sometimes together with waste disposal. Developing the bioenergy might reduce the reliance on fossil fuel and greenhouse gas emissions and increase regional incomes. Thermochemical conversion and biotechnologies for biomass and wastes are the two most important bioenergy conversion methods. In order to track the latest international development of waste to energy (WtE) technologies and bring the global academic communities up-to-date advances in the field of thermochemical conversion and biotechnologies, the journal BioMed Research International aims to call for papers and to publish a special issue on the thermochemical conversion and biotechnologies of biomass and wastes. We invite authors who are leading experts in the field to contribute with original articles that are not yet published.

Potential topics include but are not limited to the following:

• Incineration and combustion of biomass and wastes for energy recovery
• Technologies of pyrolysis and gasification for bioenergy conversion
• Hydrogen production by gasification conversion and catalysis reforming
• Other thermochemical conversions for bioenergy
• Numerical simulation of thermochemical process
• Biorefinery technologies for bioenergy or chemical production
• Biological fuel (e.g., fuel gas, liquid fuel) production technologies
• Biodiesel synthesis chemistry and thermodynamic analysis
• Anaerobic digestion process for biogas and bioenergy production
• Enzymatic catalysis for bioenergy production
