Circular economy using biocatalysis (and rotating bed reactors)

The city of Nan in Thailand accumulates 60-70 tons of waste per day. They are spending 10-15 million Baht each year, and the waste has only been going into landfills that are filling up faster than anticipated. Vidyasirimedhi Institute of Science and Technology (VISTEC) researchers Prof. Dr. Pimchai Chaiyen, Dr. Thanyaporn Wongnate, Dr. Nopphon Weeranoppanant and their co-workers in the C-ROS project are presenting an alternative using biocatalysis.

"This microbial community plays a key role in the process of converting food waste into value-added products."
- Dr. Thanyaporn Wongnate

The C-ROS project is changing the way villages handle their waste. The organic waste is converted into biofuels, fertilizers and other value-added biochemical products, and the villages recover the value for the immediate benefit of their own community.

"Food waste is ground into smaller pieces and fed into the fermenter which can be directly connected to the gas outlet that is ready to use. The gas is passed through a scrubber to absorb other impure gases first, while the biofertilizer can be drained from the tap below and is ready to use."
- Dr. Nopphon Weeranoppanant

"Now the people in the communities can sustainably manage the system by themselves, thus this is an integrated circular economy."
- Dr. Thanyaporn Wongnate

"When trash is valuable, trash is no longer waste"
- Prof. Dr. Pimchai Chaiyen


SpinChem are proud to play a role in the efforts as best we can; with our reactor technology being used for biocatalysis.
Over 20 researchers from four different institutions (VISTEC, Burapha UniversityMahidol University and Chulalongkorn University) are collaborating on the C-ROS project.

Do you have a project involving biocatalysis? SpinChem can help you realize an efficient process using our rotating bed reactor technology. Get in touch for a no-obligations introduction.
