Waste management is the biggest roadblock to a cleaner Chandigarh

The city, which ranked second cleanest in the country in the Swachh Sarvekshan-2016 survey, is struggling

Waste segregation and recycling

Of the 370 tonnes of waste generated in Chandigarh daily, 270 tonnes goes to a garbage processing plant run by a private company which makes refuse-derived fuel pellets. The remaining 100 tonne goes directly to the dumping site. As is the wont of dumping grounds across the country, here too those living around the site have to suffer the most. The private operator has also threatened to shut down the plant if Municipal Corporation Chandigarh (MCC) does not pay the tipping fee. The Corporation on the other hand, refuses any payment on the ground because it transports the waste to the plant. Read more

Waste Management proposes changes to Omaha’s trash and recycling collection

OMAHA, Neb. —Waste Management has submitted proposals to overhaul waste collection in Omaha, Mayor Jean Stothert said in a release Monday.

Waste Management’s current contract with the City of Omaha goes through 2020.

Mayor Stothert said she requested proposals to address “frequent complaints about the current level of service and plan for the future.”  Read more

Gone to waste: How India is drowning in garbage

Travelling from central Delhi towards Ghazipur in the city’s east, the first warning that you get of the approaching landfill is the sight of circling birds of prey. The mound of waste itself becomes visible much before one is assaulted by its stench. Smoke rises steadily from the pile, as the decomposing waste generates highly combustible methane gas. Read more

Cabinet likely to approve policy for producing more compost from municipal garbage

NEW DELHI: In its bid to push production of compost from municipal solid waste, the Cabinet on Wednesday is likely to approve the proposal to provide subsidy to cities that will take up this task vigorously. As per the proposal, the fertilizer ministry will provide Rs 1,500 subsidy to city administration and municipal bodies for selling every tonne of such compost.

The proposal also includes making it mandatory for the urea marketing companies to sell compost from municipal waste. Sources said the norm is likely to mandate selling of 3-4 bags of compost for every 6-7 bags of urea. Read more

BMC CONFIRMS NEW DUMP YARD IN MULUND, LOCALS RAISE A STINK

The BMC confirmed a new dumping ground at Mulund even as city activists are planning to meet Chief Minister Devendra Fadnavis, Municipal Commissioner Ajoy Mehta and Maharashtra Pollution Control Board authorities to discuss the mismanagement of the city’s solid waste.

Thirty-two hectares of land at Mulund, near the Airoli Bridge, has been allocated for solidwaste management. This means that the new proposed dumping ground at Airoli Bridge, and the existing dumping grounds at Kanjurmarg, Chembur and Mulund will take all of the city’s solid waste. The plan is being opposed by locals and Nationalist Congress Party. Read more

Peeping into the Future of Waste

Waste management is an important tool for curbing climate change and for keeping our environment clean and healthy. Methane generated from biodegradable wastes is a powerful greenhouse gas, and when it’s not captured and used as a fuel it contributes to rapid warming of the atmosphere. Estimates suggest that biodegradable waste in dump sites and uncapped landfill sites are contributing far more methane to the atmosphere than previously thought. What’s more, urban food waste is predicted to increase by 44% from 2005 to 2025, and with no proper management in place, will significantly add to global greenhouse gas emissions. Read more

Sop on sale of compost made up of waste

NEW DELHI: Pushing its mission of converting “waste to wealth”, the government on Wednesday approved the proposal to provide financial incentive of Rs 1,500 per tonne on the sale of compost made from municipal waste. The Cabinet also made it mandatory for power discoms to buy 100% power generated from municipal waste.

These decisions aim at reducing the pile up of solid waste in cities aggravating the problem of shrinking dumping sites in and around urban areas. Read more

Pay hefty fine for littering trains, railway stations

New Delhi: When in a Railway station, you may have thrown a banana peel or an empty packet of chips on the railway tracks, and got away without anyone needling you. Not any more!

If you are caught littering the train, railway track or railway premises, you may be charged a fine of up to Rs 500 for the casual act. Read more

Science Behind Deonar Landfill Site Fire

Following satellite images dated January 2016 taken by NASA show the landfill site fire at Deonar, Mumbai. The landfill fire caused serious drip in air quality & smog around the city for several days.

Why Landfill Site Catches Fire?

A landfill fire occurs when waste dumped of in a landfill site ignites & fire spreads. In landfills that do not cover their waste with daily cover of soil, biological decomposition creates substantial heat & methane. This flammable combination of heat and methane gas cause materials in the landfills to spontaneously ignite.

Landfill methane & fire

What most of us do not know is: Municipal Solid Waste disposed of in landfill generates 2 to 15 kg of “landfill gas” per metric ton of waste per year. Landfill gas generally contains 45-60% methane and 45-60% of Carbon Dioxide.[Source] Methane is 25 to 30 times more potent green house gas and contributes marginally to global worming. Methane generated from landfill sites is highly flammable. Typically the landfill site has about 100 to 300 feet height of garbage stacked over area of several hectors. Such a huge mass of garbage generates hundreds of kilograms of methane every day. Thousands of kilograms of methane remains trapped several feet below surface, waiting to ignite.

Large scale landfill fires indicate lack of following preventive measures:

  1. Scientific Waste Management: Effective segregation, material  recovery and composting of daily municipal solid waste. Government of India has established MSW Rules 2000 for effective management and handling of municipal solid waste. Machinery and Technology is now available to recycle up to 80% of municipal solid waste. This ensures that only 20% quantity of waste reaches landfill site & thereby reduce the fire risk and landfill emission by 80%.

  2. Cover the landfill with scientific layer of rock bed, geo-textile and soil. Drill methane capture wells in the landfill sites to collect underground methane to fire/explosion.landfill methane collection
  3. Methane Capture (and Flaring/ Waste to energy): The landfill gas must be captured using a scientifically proven methods to prevent landfill fires. Captured methane can be used for energy generation.

  4. Bio-remediation and scientific landfill site closure: Bio-remediation is the use of biological methods to degrade, disintegrate, transform and/or eliminate contaminants from municipal solid waste. Bio-remediation is a natural process that utilizes the normal life functions of bacteria, fungi & plants. Bio-remediation and scientific closure of landfill site is essential to prevent fire and emission of hazardous landfill gas.
    Landfill site closure

Every day millions of tons of solid waste is sent to landfill sites without scientific measures. In near future, lack of scientific waste management can lead to large scale fires similar to Deonar landfill site across India & globe.

The proposal also includes making it mandatory for the urea marketing companies to sell compost from municipal waste. Sources said the norm is likely to mandate selling of 3-4 bags of compost for every 6-7 bags of urea.

India produces around 62 million tonnes of urban waste annually, but most of it is not recycled. At present, annually about 1.5 lakh tones of compost from such waste is made while the potential is 50 lakh tonnes, sources said.

“The Cabinet proposal is to push the production. Until we have the supply, how can we expect people to buy them? Already as per the Swacch Bharat Scheme 20% viability gap funding can be provided from the sanitation programme to convert waste into manure. This will help the municipal bodies, which are facing huge shortage of space to dump solid waste,” a government official said.

Way back in 2004, the Supreme Court had directed Centre and state governments to take necessary steps and prepare an action plan for management of municipal solid waste in Metro cities and states capitals.
