Rajkot’s Sustainable Model for Dumpsite Remediation: The city turned a decades-old dumpsite, burdened with 16 lakh tonnes of legacy waste
The approach to solid waste management changed significantly with the launch of Swachh Bharat Mission in 2014. The introduction of the Solid Waste Management Rules, 2016, emphasized the goal of zero waste to landfill. SBM-U 2.0 has further strengthened this vision. It promotes sustainable waste management practices. It also introduces the “Lakshya Zero Dumpsite” initiative led by MoHUA. As part of this initiative, several cities across diverse geographies have undertaken the remediation of legacy waste sites.
“Rajkot Transforms 16 Lakh Tonnes of Legacy Waste into Urban Forest”
Rajkot serves as a compelling example of this transformative initiative. The city generates approximately 700 tonnes of municipal solid waste per day. Historically, all of this waste was disposed of at the Nakrawadi dumping site. Over time, the site accumulated nearly 16 lakh tonnes of legacy waste. In response, the Rajkot Municipal Corporation undertook a landmark effort to remediate the site. The goal was both to eliminate the waste and to turn the area into a clean urban forest. This effort led to the reclamation of 20 acre land.
As part of the Nakrawadi site remediation, a detailed survey was conducted to assess the legacy waste. Advanced machinery was then used for processing. This resulted in the segregation of refuse-derived fuel (RDF), semi-compost, and inert materials. “The team transported the RDF to the waste-to-energy plant in Jamnagar. They sent inert materials to a Secured Landfill Facility (SLF). They used over 50,000 tonnes of semi-compost for land leveling and soil enrichment.”
“Nakrawadi Waste Site Transformed into Thriving Green Space with 2.35 Lakh Trees”
To restore the site into a thriving green space, the team planted approximately 2.35 lakh native and fast-growing trees using the Miyawaki technique and laid a 12 km pipeline.
It connects the site to the Gauridad Sewage Treatment Plant. This enables the use of secondary treated water for irrigation. To ensure sustainable water management, they created water-harvesting ponds to recharge groundwater. They installed drip and sprinkler irrigation systems to optimize water use. These systems support the plantation.
The remediation of legacy waste at the Nakrawadi site faced several significant challenges. Managing over 16 lakh tonnes of mixed and compacted waste made segregation and processing difficult, while the site’s heavy contamination required extensive land preparation and soil enrichment. Workers and nearby residents were affected by foul odors and air pollution, posing health risks. Monsoon rains disrupted operations, and the need for a steady supply of treated water for plantation required the laying of a 12 km pipeline.
This project demonstrates a circular economy approach by transforming a degraded dumpsite into a thriving eco-friendly urban space. It enhances biodiversity and promotes sustainability. At the same time, it addresses the challenge of legacy waste. The waste was processed into usable materials and valuable resources for the benefit of the 30-acre green transformation initiative.
“Sustainable Waste-to-Resource Project Driving Circular Economy & Climate Action”
The project has demonstrated significant financial, social, and environmental impacts across various domains. It promotes resource conservation by recycling legacy waste into useful products. This reduces the need for raw materials. It also curbs resource depletion. The initiative uses effective waste minimization strategies like segregation, recycling, and repurposing. As a result, it reduces the volume of waste sent to landfills. This supports a circular economy. It also contributes to water conservation. The project uses secondary treated water from the Gauridad STP for irrigation via a 12 km pipeline. This lessens the dependency on freshwater resources. It enables sustainable water use in the urban forest. In terms of GHG reduction, the project converts waste into RDF for energy generation. It undertakes afforestation efforts. These actions lead to substantial carbon sequestration and climate change mitigation.
“Sustainable Urban Development Through Afforestation, Waste Management & Community Engagement”
The project also ensures health and safety by improving air quality through afforestation and waste processing. This process reduces pollutants and boosts oxygen levels. Creating green spaces contributes to the community’s well-being. It engages local self-help groups (SHGs) and volunteers. This fosters employment opportunities. It also encourages community participation and awareness about sustainable practices. As a result, it enhances social cohesion. On the economic front, the transformation of waste into energy, compost, and other value-added products generates new income streams, supports eco-tourism, and reduces the local government’s financial burden for waste management. Finally, the initiative also serves as a model for sustainable urban development.
The success of this project offers a potential for replication in other cities and regions that are facing challenges with legacy waste management, land degradation, and environmental restoration.
