From Waste to Wellness: Kolkata Startup Spentigo Redefines Sustainable Nutrition

A breath of fresh air is rising in India’s sustainable food sector thanks to Spentigo Sustainability Solutions. Led by founder Radhika Lakhotia and based in Kolkata, this startup is upcycling spent grains from breweries into a high-protein, fiber-rich flour — dubbed “Fit Flour” — making nutrition more affordable and tackling environmental waste at the same time.

What Spentigo Is Doing

From brewery by-product to healthy staple: Spentigo sources the leftover grains that breweries discard (known as spent grain). Instead of letting this go to waste, they process it into flour with roughly 30% protein, 40% fiber, and less than 5% naturally occurring sugar.

Affordable pricing: Their flour is priced at about ₹65 per kilogram, so that consumers don’t have to choose between health and cost.

Wider acceptance: Their product has earned approval from companies like ITC, and is already being used by over 100 bakers. Also, brands such as Bajo Foods are incorporating it into their recipes.

Nutrition + sustainability + social impact: Their model isn’t just about food. It addresses multiple challenges: reducing food waste, offering affordable nutrition especially for protein-and-fiber-deficient populations, and helping rural women by creating work opportunities in sourcing, processing, or distribution.

Why Spentigo Matters

In India, many face two problems at once: lack of accessible nutrition (especially protein and fiber) and huge amounts of food or agri waste. Spentigo is tackling both:

Environmental impact: Breweries produce tons of spent grain which often ends up being wasted. Spentigo’s process diverts that waste and gives it new purpose.

Health implications: Low protein diets and fiber deficiency are serious health issues. Spentigo’s flour offers a boost in both, making it useful not only for conscious consumers, but also in settings where affordability matters most.

Empowerment: The enterprise also weaves in social value — by working with rural suppliers, small bakers, and women in the value chain, it spreads economic benefits beyond just the founders.

Where They’ve Reached & What’s Ahead

Spentigo isn’t just an idea — it’s a working business. They are incubated with IIM Bangalore, which gives them access to mentorship, market connections, and deeper business insights.

Going forward, their goals appear to include scaling up production, expanding reach to more bakeries and grocery stores, and strengthening the supply chain (especially for rural sourcing).

A Real-World Example

Imagine you’re baking bread at a local bakery. Instead of regular flour, you mix in the Fit Flour from Spentigo. The bread tastes great, has more nutrition, costs about the same, and you’re contributing to less waste. That’s what Spentigo wants — to make sustainable, healthy food an easy, natural choice for everyone.
