16-09-2017 - Collect, process, generate ,The Hindu Business line:Ramky Enviro Engineers Ltd uses solid waste to generate electricity

Managing urban waste is a major challenge local body and corporations are faced with. What better way than tackling the problem with an integrated waste to energy management project. Ramky Enviro Engineers Limited, a Hyderabad-based company specializing in waste and environment management solutions, has set up a ₹650 crore Municipal Solid Waste Management project in Delhi, which not only tackles tons of waste generated every day but uses the solid waste to generate electricity through a 24 MW power project..

Delhi MSW Solutions Limited, the special purpose vehicle, and a subsidiary of Ramky group bagged the project in 2009 to collect, process and dispose the waste. The processing facility has capacity to treat 2,000 tons per day from select zones of Rohini and Civil Lines in Delhi.

“This is the country’s largest waste to energy plant,” says M Gautham Reddy, Managing Director of Ramky Enviro Engineers Limited. “Most urban bodies require such projects as waste management are a major problem. This can be replicated and urban areas and smart cities will offer big opportunity to set up such projects.” Even today, less than 10 per cent of the 22,000 tonnes of waste generated per day is scientifically managed. The country requires a number of such projects, he said.

In what the company describes as a ‘cradle to grave’ approach, multiple processes have been deployed in the project. These include composting, refuse-derived fuel and thermal processing. Thermal processing involves waste to energy conversion to minimize the waste put into landfills.

The municipal waste is segregated into wet and dry. The wet waste is aerobically treated for compost as a soil conditioner and the dry waste is converted into thermal power. Thus the refuse derived fuel, as it is known, is burnt in a boiler through a process called MSW combustion. The reciprocating grate, referred to as fuel, is burnt and the resultant heat is converted into steam. The steam thus generated runs the turbine, which in turn generates electricity that is then supplied to the grid.

“We have two combustor plants at Bhuvana industrial area in Delhi. They have capacity to handle 4.8 lakh tons of waste per annum. The 24 MW power plants generate 130 to 135 million units per annum. This is supplied to the discoms at ₹7.03 per unit,” Associate Vice President, DBSSR Sastry, explained.

After generating power, the residue is further treated. The gas coming out of the two combustors gets treated with milk of lime and activated to reduce heavy metal pollutants. The neutralized effluent is used to quench the bottom ash and partly used to control dust emission within the waste pit. The process is as required by the Delhi Pollution Control Board, with emissions monitored online.

At the same time, the biodegradable composted material, which is around 150 tons of soil enricher, goes to fertilizer selling units. The plant has residues of about 25 per cent of the waste. This goes as landfill. Efforts are on to explore alternative use of the bottom ash generated from the incinerator.

The environment ministry has accorded clearance to expand the power plant capacity by another 24 MW. Meanwhile, the company is executing another project.

“It will have the potential for 2,400 tons of waste and a 48 MW waste to energy power plant. However, in phase one, which will be completed by end of 2018, 19.8 MW unit is proposed to be operational,” Sastry explained.

16-09-2017 - Ramky Enviro commissions 24 MW waste-to-energy plant in Delhi

Ramky Enviro Engineers Ltd, through its subsidiary Delhi MSW Solutions Ltd (DMSWL), has commissioned a ₹650-crore, 24 MW waste-to-energy plant in Delhi..

The plant has been synchronised with the grid and commercial production has commenced. The Delhi Electricity regulator has fixed the tariff at ₹7.03 per kWh.

The plant combusts 1,200-1,600 tonnes per day of waste incineration with 2 MSW combustors each of 600-800 tonnes and electricity generation capacity of 24 MW.

After the inauguration of the project, Union Urban Development Minister M Venkaiah Naidu said it is aligned to the spirit of the SwachhBharat Mission, the flagship project of Prime Minister Narendra Modi.

Alla Ayodhya Rami Reddy, Chairman of the Hyderabad-based Ramky Group, said the commissioning of the waste-to-energy plant ushers in a new phase in the country’s waste management industry. The technology marks the beginning of a new era in urban waste management, more specifically for large municipal corporations, he added.

The project deploys multiple processes such as composting, refuse derived fuel and waste-to-energy (thermal processing) to derive optimum advantage of processing to minimise the landfill foot print of the residues. The processing facility has a capacity to treat 2,000 tonnes a day. The plant can produce about 150 tonnes per day of city compost which is sold as a soil enricher through multiple fertiliser selling companies.

The plant is equipped with reciprocating grate technology coupled with semi dry type flue gas treatment system and helps control particulate emissions, said the company.

16-09-2017 - India’s largest solid waste-to-energy plant launched at Delhi’s at Narela

North Delhi Municipal Corporation launched India’s largest waste-to-energy plant at Narela-Bawana on Friday. M Venkaiah Naidu, Union minister for urban development, inaugurated the project at the Civic Centre. The project will use 2,000 metric tonnes of waste every day to generate 24 mega watt of energy. The North Delhi Municipal Corporation launched India’s largest waste-to-energy plant at Narela-Bawana on Friday.

Venkaiah Naidu, Union minister for urban development, inaugurated the project at the Civic Centre. The project will use 2,000 metric tonnes of waste every day to generate 24 mega watt of energy.

The plant is expected to provide respite from overflowing landfill sites in Delhi as it will incinerate the waste to generate power. Delhi has four landfill sites, of which three — Bhalswa (North Delhi), Ghazipur (East Delhi) and Okhla (South Delhi) — are overflowing.

The landfill site at Narela-Bawana, which is also hailed as the first “scientifically” engineered landfill in Delhi, is the only one that still has capacity left.

Biodiversity meet generates 9.2 tonnes of trash!

It was generated by over 1,000 delegates from 65 countries in five days

Ramky personnel handling the waste generated at the biodiversity meet in Hyderabad.

Biodiversity is all about the variety of life on earth and how to protect it. But the ongoing global summit on this important subject has generated a variety of trash.

An incredible 9.2 tonnes of solid waste was generated during the five-day Meeting of Parties (MoP) which concluded on Friday. This huge waste was generated by over 1,000 delegates from 65 countries in just five days. It includes paper, plastic, metal, glass and food.

When the conference opened on October 1 the waste was mere 130 kg. The next day it increased to 630 kg and the third day touched 2.1 tonnes. On the fifth day when the MoP ended, a whopping 3.4 tonnes waste was generated.

Ramky Enviro Engineers, who are handling the waste produced in biodiversity event, are surprised at the sheer amount of waste produced. No prizes for guessing how much litter will be generated during the 12 day Conference of Parties 11 (CoP) beginning on Monday.

Two trucks

Blue, green, red, white, terracotta bins can be seen strategically placed at the sprawling HICC and HITEX with paper, food, plastic, glass and metal waste labelled on them. A total of 20 sets are placed. Ramky has deployed two managers, four supervisors and 20 house keeping staff to manage the waste. Two trucks have made as many trips to shift the waste to the GHMC dumping site at Jawaharnagar.

“All this will be recycled to reduce the impact of waste to a sustainable manner,” a Ramky official said. Of course, the whole thing is being done according to the guidelines of Municipal Solid Waste (Management & Handling) Rules, 2000.

Many delegates throw away the left over food along with the paper plate in a bin. “We tell them to dispose the food in the food bin and plate in other bin,” the official said.

In fact, the multicoloured bins are intended to educate delegates and visitors alike about segregation of waste at source. It is a proactive education that Ramky engineers have taken up to create awareness among the participants about collection, segregation and disposal of waste.

Covered by black disposable covers, the filled in bags are carried by the housekeeping staff to designated places for bulk collection through pull push 1100 litre carts at Hitex and HICC areas.
