The _______ process is a type of process mainly used to recover energy from solids in one form or another.

Explanation:

1) Thermal Process:

• Definition: A thermal process is primarily used to recover energy from solid materials, such as waste or biomass, by applying heat.
• Examples: Incineration, gasification, and pyrolysis are common thermal processes that convert solid waste into energy by burning it or converting it into gas or other forms of usable energy.
• Usage: These processes are widely used in waste-to-energy plants to recover energy from municipal solid waste, agricultural residues, and other biomass.

2) Pressure Process:

• Definition: This process involves the application of pressure to materials. It is typically used in industrial applications for shaping, molding, or compressing materials, not for energy recovery.
• Usage: Common in manufacturing processes, such as metal forging, and hydraulic press operations.

3) Biological Process:

• Definition: Biological processes involve the breakdown of organic matter using microorganisms.
• Examples: Composting and anaerobic digestion, where organic material is decomposed by bacteria to produce biogas or compost.
• Usage: While biogas production from biological processes can recover energy, this method mainly relies on biological activity, not thermal means.

4) Chemical Process:

• Definition: Chemical processes involve the use of chemical reactions to convert substances into different forms.
• Examples: Chemical recycling, such as depolymerization of plastics, or the production of biofuels from chemical conversion of organic materials.
• Usage: Although chemical processes can recover energy, they are distinct from thermal processes that primarily use heat.
