How did it start?

The founder, during her tenure with multinational companies, realized that if she had to set up a manufacturing unit of her own as an MSME, she would not be able to afford the technologies of these MNCs. Keeping that in mind, Royal Bengal Greentech commenced to provide affordable, sustainable solutions to manufacturers.

Quick Overview

Area of Operations

RBG has 3 different verticals so far–bioethanol (conversion to waste broken rice into ethanol) for which they collaborated with Jadavpur University, Kolkata; bioplastics which are the world’s first cost-effective bioplastic and bio-lubricants which is supplied to 7 states in India in both industrial and automotive sectors in India.

Key Innovations

Throughout a year since incorporation, some of the key innovations delivered by us include:

· The world’s first patented agri-waste derived, cost-effective, thermosetting, heat resistant, 100% Made-in-India, biodegradable plastic, using 100% natural ingredients priced at par with petro-plastic relative to three times costlier biodegradable alternatives.

· Patented next-gen bioethanol technology from waste-broken rice at up to 2x profitability – developed jointly in collaboration with the Department of Chemical Engineering, Jadavpur University Kolkata –pilot testing planned in Q4 2023.

· Next-gen cost-effective biodegradable grease–commercially available in 10+ cities in 5+ states across India for various automobiles as well as industrial machinery.

Market Penetration

The penetration has been challenging for Royal Bengal Greentech in terms of finding the right market for bio grease. The startup has already reached the breakeven stage in only 6months of its operation. Companies like Berger Paints and Tata Steels have shown their interest in collaborating with RBG.

Revenue Model

Currently, there are two models of revenue for the startup–Sales and Licensing. The sales part currently is only limited to B2B and licensing to B2B.

Expansion Plans

The sales revenue model is expected to extend to B2C and B2G for RBG. The plan is to cover all the states in India and then go global.

SWOT Analysis

The strength of the company is its product and team. The domain of sustainability is the need of the hour.

The weakness is team building with respect to expansion in the business.

The opportunity is immense since the traction that sustainability has on the world is huge.

The threat is the competition from petroleum majors as they have a monopoly over the raw products.
