Ghazipur Landfill Catches Fire Due To Heat, Here Are 5 Things To Know
The Municipal Corporation of Delhi (MCD) believes that Ghazipur landfill caught fire due to the methane generation at site and high temperature afternoon, a massive fire broke out at the Ghazipur dumpsite (commonly known as landfill), one of the three garbage mountains in Delhi. As quoted by news agency ANI, according to the press release by the Municipal Corporation of Delhi (MCD), the fire broke out at around 1:30-1:45 PM in the afternoon and soon began to spread due to strong winds. “MCD quickly responded to the situation and 8-10 fire tenders from the Delhi Fire Department and 13-14 excavators and 4-5 bulldozers working at the landfill site were pressed into action to control the fire,” added the release. he MCD believes that the cause of the fire was the generation of methane gas coupled with high temperature in the national capital Delhi. However, it was controlled using inert material. Spread across 72 acres of land, Ghazipur, the oldest dumpsite in Delhi, was commissioned in 1984 and crossed the permissible height of 20m in 2002. It has been overflowing since then and stands at around 40 meters, as per the MCD. As per the data received from the MCD, 140 lakh tonnes of legacy waste has been dumped on the Ghazipur site as of July 2019. 5 Reasons Why Landfills Catch Fire: In an interview with NDTV, Ashok Kumar Jaiswal, Divisional Officer, Delhi Fire Services said, “It is summer time and decomposition of organic waste amid heat often leads to chemical reactions and generation of gases like carbon monoxide and hydrogen sulfide. Frankly, during the summer season, landfills catch fire automatically. Yesterday, we managed to douse the fire with the help of 13 fire tenders.” Ghazipur landfill is technically a dumpsite, a mere piece of land where waste is being dumped recklessly. Dr. Richa Singh, Deputy Programme Manager, MSW (Municipal Solid Waste) team, Centre for Science and Environment explains, “While sanitary landfills are scientific structures or containment systems which are engineered and constructed in a way to isolate waste from the surrounding environment, dumpsites are mere pieces of land without any mechanism for pollution control.” Dr Singh adds that sanitary landfills have barriers of high-density polyethylene and mechanisms to collect and treat leachate (contaminated liquid generated when water percolates through waste), alongwith the ability to collect landfill gas, which primarily consists of methane and treat that as well. “Living around dump sites comes with health challenges as people in close vicinity are exposed to gases like the colourless and odorless Methane, trace gases like H2S (Hydrogen Sulfide), as well as high levels of Particulate Matter and Ammonia,” says Dr. Singh. These gases are carcinogenic in nature. Long-term exposure to these gases can result in respiratory disorders, and at times it can lead to cancer as well. On dumpsites, while biodegradable or wet waste decomposes over time, the anaerobic decomposition (breakdown of organic waste in the absence of oxygen) of organic waste generates methane gas, which is flammable and generates heat. That’s the reason why dumpsites in Delhi, especially in summer, often catch fire. If not fire, then these are always smoldering in patches. To prevent such fire outbreaks, Dr Singh recommends an interim solution (till the remediation of all the legacy waste is done) which includes, A gas collection and treatment system for landfill gases. Moreover, landfilling of biodegradable and combustible waste should not be done in the first place to prevent the leachate and landfill gas issue.
