Our journey into market waste management began back in 2017 with a conversation with Mrs. Sandhya, Medical Officer of Health, whom we met during our work in Amruthahalli. She was deeply appreciative of the enthusiasm and energy we brought to our zero waste initiatives there. During our discussion, she mentioned something that stayed with us —
“No one is really working on waste management in markets. NGOs avoid it because it’s messy and complicated.”
That statement struck a chord. It was true — markets were generating enormous amounts of waste every single day, and yet, no one was addressing it seriously, as for people in the SWM sector, the sheer mountain of waste often induces a kind of paralysis. The sight of towering, rotting piles, day after day, makes the problem seem intractable. At Vedan Trust, we understand that feeling. But we also know that volume is just an illusion. You don’t need to see less waste; you need to see a system. We decided to take this as a challenge and an opportunity.
What began as a simple conversation has since grown into a mission — to make every market a cleaner, circular space where waste is treated as a resource, not a problem.
Our team embarked on an intensive, boots-on-the-ground study of the KR Puram market. We didn’t just look at the trash; we studied the entire ecosystem.
Our field study revealed a complex web of activities and understanding of the market ecosystem
The core problem was not the volume of waste; it was the lack of intelligent division and immediate diversion. Everything was being treated as one undifferentiated, unmanageable mess.
The consequence? Unsold produce is quickly dumped into rotting piles. This creates a severe health hazard, pollutes the area, and drives away consumers who prefer the hygiene of supermarkets, leading to huge losses for honest market vendors.
Our response was the GSTAR Model. It’s a simple, systematic framework designed to defeat the perception of “unsolvable volume” by establishing clear roles, clear responsibilities, and clear destination for every single item.
GSTAR proves that when you divide the volume into four distinct streams— Reuse (Recover), Repurpose, Reduce, and Recycle—the “mountain” instantly becomes a series of manageable, high-value resources when collected at the right time and in the right way.
GSTAR is a systematic, five-step resource recovery process that ensures not a single resource is wasted:
The key to GSTAR is simple logistics: The farmer brings produce in crates and bags; the waste is collected in crates and trolleys.
This fresh, unsaleable, but perfectly edible produce is immediately diverted.
Certain items are collected separately for specialized reuse:
The sorted produce that is no longer fit for human consumption but is safe for livestock is diverted.
This is the final-mile strategy for the true remnants:
Developing G-STAR was a journey of relentless adaptation and resilience:
The timeline below shows a clearer picture of our journey in the development of the G-Star Market Waste Management model.
Our success at Madiwala Market reinforced an important lesson: the challenge was never the quantity of waste—it was the absence of a well-designed system to manage it.
Markets operate for long hours, involve multiple stakeholders, and generate diverse waste streams throughout the day. Without a system tailored to these realities, even the best intentions cannot deliver lasting results. The issue was not that the existing system was failing—there simply wasn’t one.
Vedan began by conducting an in-depth study of the market’s operations, mapping waste generation patterns, understanding stakeholder behaviour, analysing material flows, and identifying operational gaps. Based on these insights, we designed and implemented a practical, scalable waste management system that worked with the market’s unique ecosystem rather than against it.
With the support of BBMP and other key partners, this approach transformed waste management at Madiwala Market into an efficient, accountable, and sustainable model—demonstrating that the right system can convert a complex waste challenge into a manageable process.
Building on this success, Vedan is now prepared to replicate and scale this model at KR Market, one of Bengaluru’s largest, busiest, and most complex traditional markets. The commitment from government departments, market stakeholders, and implementation partners is strong. The primary challenge now is securing the financial support needed to bring the project to life.
With the right investment, we can transform disorder into a well-managed system, recover valuable resources from waste, improve working conditions for market stakeholders, and create a model that can be replicated across markets throughout the country.
The challenge is significant—but so is the opportunity. We are ready for the next transformation.
Bring the G-STAR Model to Your Market
We can help you build a functional, scalable waste management system
Transform your market from unmanaged waste to a circular ecosystem.
Work at KR Market has recently begun, focusing on understanding waste flows, stakeholder roles, and operational gaps in one of Bengaluru’s largest markets. Early engagement with vendors and authorities has laid the groundwork for introducing the GSTAR Model in a phased manner. This initiative marks the next step in demonstrating that even the most complex markets can be transformed through well-designed systems.
Kalasipalya Market is a powerful example of how systems—not fines—drive lasting change. When a structured waste collection system existed, roads were clean and drains were protected; once the system was withdrawn, the problem returned. Vendors continue to demand the same system, proving that behaviour change had already happened.
Madiwala Market showed how organic waste can be transformed into a community resource. Fresh produce was diverted for cow feeding, orphanages, and cattle farmers, creating a clean, zero-waste loop. It stands as a fully functional, scalable model for urban markets.
Yeshwanthpur Market focused on diverting edible and organic waste away from landfills through simple, local systems. Wet waste was redirected daily for cattle feed, while awareness and dry-waste systems were introduced in nearby schools. The initiative demonstrated clear impact but could not be sustained due to limited on-ground stakeholder support.
KR Puram Market was Vedan’s first case study, where the G-STAR Model was born. By connecting stakeholders and introducing a simple, coordinated system, the market demonstrated that structured processes—not enforcement—can solve long-standing waste challenges. It became the foundation for all future market interventions.
At Vedan, we don’t just manage problems — we redesign systems, empower communities, and create models that continue long after we leave. Your support helps scale solutions that are practical, measurable, and replicable.
