Amid the global momentum toward sustainability, bioenergy startups are increasingly focused on converting organic waste into valuable green energy resources. However, the sector continues to face significant challenges around scalability, system integration, and achieving net-zero goals. Rigel Bioenviron Solutions Pvt. Ltd. stands out as a leader in this space championing the ‘waste to wealth’ concept through a fully circular, zero-waste model that converts organic waste into biodegradable plastics, biofuels, electricity, and compost.
Dr Sanchita Mukherjee, Director
Backed by deep bioprocess engineering expertise and strong government collaborations including international projects in Mauritius and Africa, the firm delivers a comprehensive, legally compliant Bio Resource Management System. The company’s innovative technology seamlessly integrates with both municipal and industrial infrastructures, effectively eliminating landfill dependence and water waste.
More than just waste management, Rigel Bioenviron is engineering sustainable, scalable solutions for a cleaner, greener future.
Balancing Affordability
At Rigel Bioenviron Solutions, cost-effectiveness and environmental responsibility go hand-in-hand. By transforming organic waste into high-value green products like biodegradable plastics, biofuels, and compost, the firm significantly lowers production costs, since the raw materials are essentially waste, not high-cost pure feedstock. “Our proprietary continuous process is not only efficient but also retrofittable to existing facilities such as sewage treatment plants and ETPs, enhancing value without heavy infrastructure investment.
As global demand for eco-friendly solutions grows, economies of scale are driving prices down, just as we’ve seen with mobile phones or RO systems”, speaks Dr Partha Chakravarty, Director, Rigel Bioenviron Solutions. With government policies favoring biodegradable alternatives and environmental mandates increasing, Rigel Bioenviron Solutions is positioned to deliver sustainable innovation that's both economically viable and ecologically essential.
Despite early client hesitation, often rooted in uncertainty or capital concerns, Rigel Bioenviron Solutions has established itself as a true catalyst for change. With government mandates and incentives increasingly pushing for biodegradable alternatives, market interest has gained strong momentum. By lowering capital barriers and building client confidence, the company makes the transition smoother and more accessible. Especially in industrial sectors, where waste streams are abundant, Rigel Bioenviron Solutions' model delivers high-value returns, producing biodegradable plastics and biofuels from what was once discarded material.
Customer-Centric Solutions
At Rigel Bioenviron Solutions, customer feedback is at the heart of innovation. Every project, whether a government-funded pilot or a large-scale deployment offers valuable insights. With variations in waste types, climates, and industrial needs, the firm conducts detailed feasibility studies and customizes its technology for specific substrates, industries, and energy goals. This feedback-driven approach has led to patent-worthy design improvements and more robust systems capable of handling diverse biomass sources.
The firm is a government-backed clean-tech startup on a mission to transform organic waste into high-value, biodegradable products. Currently the company is committed to cutting carbon emissions and helping its clients earn carbon credits. Through its DBOM (Design, Build, Operate, Maintain) models, the firm provides complete, end-to-end support to ensure long-term performance and innovation. Its patented technology, India’s first that turns organic waste into green plastic, has firmly positioned the company as a market leader. Strong partnerships with top academic institutions like the IITs fuel its ongoing research and development efforts.
Recognized with major honors, including the Best Startup Award from BIRAC, DBT (2024) and a finalist spot at the 15th Aegis Graham Bell Awards (2025), Rigel Bioenviron Solutions is on track to become market leader within the next five years. With its groundbreaking solutions, the company is playing a crucial role in shaping India's circular economy and sustainable energy future.
