US-based alternative feed ingredients firm Calysta has unveiled a $39 million (€33 million) investment aimed at funding the company's global expansion plans.

The latest funding round was led by oil and gas giant BP's venture capital arm, ChemChina-owned feed giant Adisseo, private equity group Aqua-Spark, WTI and other existing investors.

The expansion of the funding round will support scoping and pre-development of the company’s next manufacturing site outside Asia.

Calysta expects the first phase of its Feedkind single-cell protein plant to start production in China before the end of next year, after investing heavily in research, development and production of its ingredients.
