The Kochi Corporation has announced a plan to reduce its annual expenditure on waste collection, transportation and treatment from about ₹20 crore to less than ₹10 crore within a year, and to achieve net-zero municipal spending on waste management within two-and-a-half years.
Roadmap targets savings through technology, public‑private partnerships and in‑house capacity
The local body, whose own revenue (excluding government allocations) is around ₹160 crore, currently spends roughly 17% of that on waste services. The health standing committee chairperson, Seena Gokulan, said the city prepared the plan after the March 2023 fire at the Brahmapuram solid waste treatment plant prompted a review of handling and treatment systems. She told corporation members the cost of waste management had risen significantly in recent years and the new measures aim to reverse that trend.
Key steps detailed by the corporation include:
- Ceasing payment to an external incinerator operator and switching to the corporation’s own incinerator for sanitary waste, which has already saved ₹3.3 crore per year.
- Adopting black soldier fly technology at Brahmapuram for biowaste treatment, where current treatment charge is ₹2,500 per tonne.
- Pursuing a public–private partnership for a biowaste treatment plant: the corporation proposes leasing three acres to a private firm that would set up the plant and treat biowaste without charging the corporation, while charging ₹200 per tonne for transportation if it handles collection.
- Exploring plastic‑to‑fuel technology by sending a delegation led by Mayor V K Minimol to study a plant run by Gati Shakti Vishwavidyalaya at Baroda.
Financial and operational context
Health standing committee member Henry Austin said the planned PPP model for biowaste would substantially reduce transportation and treatment costs. The corporation has prepared a detailed report on expenses related to collection, transportation and treatment and intends to implement the roadmap during the current council’s tenure.
“If our plan works, the cost can be brought down to less than ₹10 crore in a year. Our aim is to finally generate profit from waste within the tenure of the current council,”
said Seena Gokulan, summarising the council’s target.
The corporation had previously relied on an incinerator run by Kerala Enviro Infrastructure Ltd (Keil) at Ambalamugal; its services were discontinued in August and the corporation shifted to its own incinerator for sanitary waste disposal, accounting for the reported annual saving of ₹3.3 crore.
| Item | Current/Reported |
|---|---|
| Annual waste-management spending | ₹20 crore |
| Target within one year | <₹10 crore |
| Corporation own revenue | ₹160 crore |
| Share of revenue spent on waste | 17% |
| Black soldier fly treatment charge | ₹2,500/tonne |
| Proposed transport charge (PPP) | ₹200/tonne |
Implications for service and environment in Kochi
Officials emphasised that cost reduction should not compromise service levels. The corporation’s strategy combines immediate savings from in‑house operations with medium‑term investments and private participation to scale up treatment of organic waste and address plastic processing. The move follows public concern after the Brahmapuram fire and aims both to improve resilience and to lower the municipal fiscal burden.
Implementation will require careful contracting, monitoring of technology providers (including the black soldier fly systems) and safeguards to ensure environmental compliance. The mayor’s planned study visit to the Baroda plastic‑to‑fuel plant signals interest in diversified waste‑to‑energy solutions beyond conventional incineration.
Municipal finance watchers say success will depend on transparent tendering for PPPs, realistic timelines for plant commissioning and sustained segregation at source to feed biological treatment units. The corporation’s stated objective of turning waste management into a revenue source during the current council’s term marks an ambitious shift from subsidy‑dependent operations to an efficiency‑and‑technology driven model.
