Material Utilization of Organic Residues

Area of Science:

• Biotechnology
• Sustainable Chemistry
• Waste Management

Background:

• Massive global generation of organic waste, including food and lignocellulosic materials, presents environmental and resource challenges.
• Current disposal methods like composting, burning, and biogas conversion often overlook the inherent value of organic residues.
• Organic residues are rich in carbohydrates, lipids, proteins, and phosphorus, representing untapped resources for the bioeconomy.

Purpose of the Study:

• To review microbial processes for converting organic residues into high-value bioeconomy compounds.
• To highlight the challenges associated with downstream processing in decentralized organic residue utilization.
• To propose a future process for lactic acid production from organic residues.

Main Methods:

• Literature review of microbial valorization techniques for organic residues.
• Analysis of challenges in downstream processing for decentralized bio-based production.
