Call For Papers - CFP

I. Green Chemical Engineering

This discipline applies the principles of Green Chemistry and Green Engineering to the design, manufacture, and use of chemical products and processes to reduce or eliminate the use and generation of hazardous substances.

1. Principles and Metrics

The 12 Principles of Green Chemistry:

Prevention of Waste (Atom Economy, Catalysis).

Design for Energy Efficiency (Ambient conditions).

Design for Safer Chemicals (Reduced Toxicity).

Use of Renewable Feedstocks (Biomass, Agricultural Waste).

Design for Degradation (Non-Persistent Products).

The 12 Principles of Green Engineering:

Inherent Rather Than Circumstantial (Materials and energy should be nonhazardous).

Prevention Instead of Treatment (Better to prevent waste).

Design for Separation (Minimize energy and materials).

Maximize Efficiency (Mass, energy, space, and time).

Renewable Rather Than Depleting.

Sustainability Metrics and Assessment:

Life Cycle Assessment (LCA): Cradle-to-grave environmental impact analysis.

Material Flow Analysis (MFA).

Environmental Performance Indicators (EPIs), Atom Economy.

2. Sustainable Reaction and Process Design

Catalysis:

Green Catalysis: Heterogeneous, Biocatalysis (Enzymes), Photocatalysis.

Design of highly selective and efficient catalysts.

Reaction Media:

Green Solvents: Supercritical CO2, Ionic Liquids, Water, Solvent-free reactions.

Alternative energy sources for reactions (Microwave, Ultrasound, Mechanochemistry).

Process Intensification (PI):

Modular and Microreactor Technology.

3. Sustainable Feedstocks and Products

Biomass Utilization (Biorefineries):

Conversion of lignocellulosic and algal biomass into fuels and chemicals.

Production of bio-based plastics and biodegradable polymers.

Circular Economy Approaches:

Waste valorization (Waste-to-Energy, Waste-to-Chemicals).

Chemical Recycling of Polymers and Materials.

Industrial Symbiosis (Sharing waste/by-products between industries).

Designing Safer Materials:

Developing non-toxic materials, flame retardants, and coatings.

II. Energy & Environmental Sustainability

This area focuses on developing and implementing low-carbon energy systems and managing the long-term health of the planet's natural resources.
