Comprehensive Solutions for Kitchen Waste Treatment | MOTIVA

Kitchen waste refers to perishable, organic-rich household waste, including leftover food, vegetable scraps, fruit peels, rotten meat, and other biodegradable materials. It encompasses household kitchen waste, food waste, and other organic residuals.

Key Features of Kitchen Waste

1. High Moisture Content: Approximately 80%-95%, leading to low calorific value and high fluidity, which complicates transportation and treatment.
2. High Organic Matter: Organic content accounts for about 95% of dry matter. It is rich in starch, cellulose, protein, fat, minerals, and trace elements, making it highly perishable.
3. High Oil Content: Contains about 2%-8% oil, which can be recovered and legally utilized.

Kitchen waste is both a pollutant and a resource — a misplaced resource that can be transformed through proper treatment.

Common Treatment Technologies

• Landfilling: Phased out since 2023 in most regions due to unsustainability.
• Incineration: A temporary solution for areas lacking waste classification systems or market acceptance of recovered products.
• Biochemical Treatment: The mainstream and eco-friendly method, including aerobic composting and anaerobic digestion for resource recovery.
