A Case for Decentralised Systems
Bengaluru today spends approximately ₹1,400 crore every year on solid waste management. This is a substantial public investment, reflecting both the scale of the city and the complexity of managing more than 6,000 tonnes of waste generated daily. Over the years, the administration has made important progress in expanding collection systems, formalising operations, and introducing user fees to improve financial sustainability.
However, the current structure of this spending reveals an opportunity. Based on available data and operational patterns, nearly 70–80% of this budget is allocated to collection and transportation—roughly ₹900–1,100 crore annually. In comparison, processing and recovery receive only ₹210–350 crore, while information, education, and communication (IEC)—critical for behaviour change—accounts for just ₹30–70 crore. In effect, the system is designed primarily to move waste, rather than to reduce or recover it.
A circular economy approach does not necessarily require more spending, but it does require rebalancing how existing funds are deployed. If Bengaluru scales 4-way segregation at source and decentralised waste systems, the same ₹1,400 crore can be allocated more efficiently. Collection costs can reduce to approximately ₹420–520 crore, as segregated waste is faster and easier to handle. Transportation costs—currently ₹280–420 crore—can drop significantly to ₹120–180 crore, since a large fraction of waste, especially wet waste, would no longer need to travel long distances.
This shift is driven by a simple but powerful fact: wet waste constitutes 50–60% of Bengaluru’s waste stream. When this is processed within apartment complexes, communities, or ward-level facilities through composting or biomethanation, it is effectively removed from the city’s transport burden. At the same time, better segregation improves the quality of dry waste, reducing downstream sorting costs and increasing recycling value. As a result, only 10–20% of total waste—rejects—requires long-haul transportation and landfill handling.
The savings generated—estimated at ₹300–400 crore annually—can then be reinvested into strengthening decentralised systems. Processing and resource recovery can increase to ₹450–550 crore, not as centralised infrastructure alone, but as a distributed network of community composting systems, biomethanation plants, and high-quality dry waste sorting centres. IEC spending can also expand to ₹120–180 crore, recognising that sustained behaviour change is not a peripheral activity but core infrastructure for any functioning waste system.
Bengaluru already has a strong foundation to build on in this transition. The city’s network of Dry Waste Collection Centres (DWCCs), operated largely by waste picker entrepreneurs, is one of the most established decentralised dry waste systems in India. These centres enable ward-level sorting, aggregation, and recycling, while also providing livelihoods and integrating the informal sector into formal waste management.
Yet, DWCCs today often operate below their potential. Inconsistent segregation at source leads to poor-quality input material, limiting recovery value. Financially, many centres depend heavily on the volatile resale market for recyclables. With better allocation of resources—particularly within the ₹100–150 crore range for dry waste systems—DWCCs can be upgraded with improved infrastructure, assured service payments, and a steady supply of clean, segregated waste. This would transform them from marginal operations into efficient material recovery hubs at the heart of a circular economy.
Even with improved segregation and decentralised processing, however, the system is still dealing with waste after it has been generated. A truly circular approach must also invest in waste prevention. Allocating even 5–10% of the existing budget (₹70–140 crore) toward prevention can have a disproportionate impact on overall system efficiency.
Bengaluru is uniquely positioned in this regard. The city is home to a growing ecosystem of sustainable enterprises working on solutions such as cutlery banks for events, menstrual cups and reusable cloth pad kits, preloved and repair platforms, reusable diapers, and refill-based retail systems. These interventions directly reduce the volume and complexity of waste entering the municipal system—particularly in high-impact categories like sanitary waste and single-use plastics.
Despite their potential, many of these enterprises operate without stable institutional support. Integrating them into the city’s waste management framework—through procurement, partnerships, and programmatic funding—can simultaneously reduce municipal costs and create a reliable demand pipeline for circular businesses. In this sense, public spending becomes not just a service cost, but a market-shaping tool.
At the community level, the economics are equally compelling. A typical 100-flat apartment can implement decentralised wet waste (~50% of total) management at approximately ₹120 per household per month, while the implicit cost of centralised municipal handling ranges between ₹1,500–2,500 per household. When communities take responsibility for segregation and local processing, the city saves on collection, transport, and landfill costs—creating a clear case for co-funding and policy support.
The pathway forward for Bengaluru, therefore, is not about replacing existing systems, but about strengthening and complementing them. A layered approach—combining waste prevention, 4-way segregation, decentralised processing, and an upgraded DWCC network—can significantly improve both environmental and financial outcomes.
Bengaluru has already invested heavily in building its waste management system. The next step is to ensure that this investment delivers maximum value. By reallocating even a portion of the current ₹1,400 crore toward decentralised infrastructure, behaviour change, and waste prevention, the city can move from a system that primarily manages waste to one that actively reduces, recovers, and reuses resources.
Such a transition would not only lower costs and environmental impact, but also strengthen livelihoods, support local enterprises, and position Bengaluru as a leader in urban circular economy practices.
