About
The microbiome, nature's most efficient factory, produces lactic acid — a versatile molecule with the potential to replace traditional oil-based chemicals in the new circular economy.
Learn more
Nature's Principles began as a PhD project at Delft University of Technology, using mixed culture fermentation and the Principles of Nature to make microorganisms productive — without genetic engineering.
Now in pilot scale production, the company aims to make bio-based chemicals viable and truly circular. Our patented fermentation platform is feedstock agnostic — working with sugar beet, waste cellulose, molasses, and other industry residuals.

Feedstock
Side Stream Processing
Sugar beet pulp, molasses, and agricultural residuals are valorized as low-cost feedstocks. Our feedstock-agnostic platform works with traditional sources and sustainable waste alternatives — eliminating reliance on refined crop sugars.
02
Fermentation
Mixed Culture Fermentation
Our patented platform uses mixed culture fermentation — no genetic engineering required. Microorganisms naturally produce L-lactic acid in their optimal environment, creating a more robust and resilient production process than conventional single-strain approaches.
03
Purification
Downstream Processing
Customized upstream, fermentation, and downstream processing solutions tailored for large-scale lactic acid production. We collaborate with clients to optimize every step — from feedstock preparation to final product specification.

Output
L-Lactic Acid & PLA
Food-grade L-lactic acid for preservation, flavoring, and industrial applications. PLA bioplastic building blocks replacing fossil-based polymers. Bio-based chemical solvents and natural disinfectants — all from the same circular process.
