TAIPEI (Taiwan News) — Feng Chia University has developed a technology that converts food waste into biochar, CNA reported Thursday.

The university unveiled an integrated energy conversion system using high-temperature atomized hydrolysis to break down oils and salts in the waste. The system offers high efficiency and rapid deployment.

Feng Chia University Professor Chu Cheng-yung (朱正永) explained that most food waste-to-energy facilities handle scrapers through anaerobic fermentation, per Liberty Times. Cooked waste, however, contains oils and salts that require pre-treatment and operational risks, he added.

The new system uses atomized hydrolysis to break down fats and complex organics. The resulting liquid hydrolysate feeds the system for hydrogen-methane biogas generation. Solids are fed into National Chung Hsing University’s gasification system.

Chu said the integrated approach eliminates the need for building new large digesters and accelerates deployment. He said the technology can be installed within nine months and process 300 tonnes of waste daily.

The system offers a practical model for local governments to promote organic waste utilization, Chu said. Feng Chia University and Riqian Limited signed a collaboration and scholarship agreement to promote the technology.
