The main purpose of the project is to develop and demonstrate a waste-to-value approach, to recover pure chemical products from organic wastes to help in the transition toward a fossil-free and sustainable society. The overall aim of this project is to establish a novel bio-based production platform through fermentation of organic waste streams and separation strategy to produce pure and market-ready functional chemicals for application in a carbon-negative process.
This project will seek to produce and purify volatile fatty acids (VFAs) (which is a building block chemical for other bioprocesses) from wastes. The focus will be on the production of ammonium acetate as a target chemical from the VFAs platform, which will be tested for calcium carbonate production from landfilled ashes and captured CO2. The specific purposes are (1) to produce and separate a waste derived VFA mixture into pure VFA flows, (2) to produce and test the ammonium acetate from separated high purity acetic acid. In this way, this project hopes to achieve a new bio-based product for the market, and it will help in the transition to a sustainable society.
