Dear Colleagues,

Many recent research programs based on energy sector are focused on the development of concepts such as renewable resources, sustainable development, green energy and eco-friendly process. Increasing world population and industrial development have all led to serious energy crisis and global warming. It is, therefore necessary to develop ecologically clean and safe energy technologies for a sustainable future.

The scope of the ACE journal covers research in chemistry, biology, materials, and allied engineering fields. Thus, in this Special Issue, we invite articles focused on research regarding the chemistry, biology, materials, and allied engineering firms.

Topics of interest for this Special Issue include but are not limited to:

· Energy saving and waste reduction in production processes

· Design and manufacturing of green products 

· Materials for green production

· Management and policy for sustainable production

· Technologies of mitigating CO2 emissions

· Waste recycling and conversion for fuel production

· Biomass feedstock and (bio)chemical conversion technologies for biofuel production
