MetaFor (“Unexplored potential of diverse plant metabolites to enhance sustainable bioeconomy and carbon sinks from forest biomasses”, Academy of Finland project no 372667) is a consortium lead by Maarit Karonen and the latest Academy project of the Natural Chemistry Research Group.
MetaFor promotes a sustainable bioeconomy by finding new, circular‑economy–driven uses for forest biomass. Our focus is on the insoluble metabolites found in forest‑industry side streams—natural compounds that can help stabilize organic carbon and bind nitrogen in soils. These processes are important for strengthening soil carbon sinks and supporting long‑term ecosystem health.
We investigate the chemistry of these insoluble fractions, especially condensed tannins, and examine how they influence plant growth, soil processes, the breakdown of organic matter, and nitrogen cycling. We combine advanced chemical analyses with plant growth experiments to understand their full potential.
A key goal is to explore whether forest‑industry residues could replace peat in various applications. By doing so, we aim to reduce the carbon footprint of soil products, improve carbon sequestration, and create new value from existing side streams. Ultimately, the project seeks to turn scientific knowledge into practical innovations that help mitigate climate change while supporting healthy soils and biodiversity.
