Plantible Foods produces a plant-based protein ingredient called Rubi Protein for other food makers. It grows lemna, an aquatic plant, in its own aqua-farms to create a scalable, sustainable protein that is free from major allergens and has a neutral taste and color. The product is sold as an ingredient to food manufacturers for use in baked goods, plant-based meats, dairy alternatives, and nutritional supplements, enabling them to formulate new or improved plant-based products without worrying about allergen issues. The company differentiates itself by controlling its supply chain through in-house aquafarming and by delivering a neutral, versatile protein that can be incorporated across many product categories. Its goal is to meet increasing demand for sustainable, healthy foods by expanding production capacity and broadening its customer base among B2B food manufacturers.

FDA clears Plantible's RuBisCO protein for commercial use in first for sustainable food ingredient

Plantible Foods has received a "No Questions" letter from the FDA regarding its GRAS notice for Rubi Protein, making it the first company to gain FDA acknowledgment for isolated RuBisCO protein in food applications. The regulatory milestone clears the way for large-scale commercial adoption. Rubi Protein is derived from water lentils grown in enclosed greenhouses and contains approximately 85% protein by weight. The ingredient offers neutral taste, high solubility and strong emulsification properties, suitable for baked goods, beverages, dairy alternatives and plant-based products. Plantible opened its first commercial facility in Eldorado, Texas, last year and plans to expand capacity to meet growing customer demand. The San Diego-based company was founded by Tony Martens and Maurits van de Ven.

Elemental Impact Injects $18.6M Into Climate Technologies Creating Jobs And Local Economic Impact

Non-profit's strategic investment tackles the funding gap between climate innovation and widespread adoption.HONOLULU and SAN FRANCISCO, Dec. 11, 2024 /PRNewswire/ -- Elemental Impact , a leading non-profit technology investor, announced today $18.6 million in investments across 16 companies deploying projects in Texas, Nevada, Oklahoma, Colorado, Tennessee, and international markets.This announcement is part of the non-profit's larger investing strategy that includes initial investments to build a pipeline of critical climate companies and projects, follow-on funding to promising projects with local impact, and the newly announced Greenhouse Gas Reduction Fund (GGRF) program for later-stage commercialized technologies, for which investments are expected to be announced in the new year.These investments represent one of the many ways Elemental continues to tackle the $150B "Scale Gap," a critical challenge and funding shortfall climate companies face during first-of-a-kind (FOAK) and early commercial deployments. While these technologies have proven their potential, this funding gap often results in a lack of necessary capital to scale up these innovations, creating a barrier to the widespread adoption."We are seeing extraordinary demand for capital from entrepreneurs who are ready to scale, but who face a critical funding gap," said Dawn Lippert, CEO of Elemental Impact. "These 16 new investments prove that philanthropy can enable projects in rural towns, Tribal lands, urban areas, and wild ecosystems -- and unlock significant private investment."After vetting more than 7,000 companies this year, Elemental selected companies representing four emerging themes: accelerating the next era of U.S. manufacturing, building a resilient supply chain, strengthening rural and tribal access, and scaling a regenerative food system. They will now join a portfolio of more than 160 companies that have created over 10,000 jobs, all working to scale their solutions and create meaningful economic benefits in local communities
