Process Description of MSW management in JITF –TOWMCL, Delhi

MSW received at site is dumped into the storage pits, any yard segregation is not envisaged. The

overhead hoists with excavative buckets pick up MSW and deposit it on to the “Vibratory cum Gross

Screening Feeders”. At this stage, while more than 95% material (size less than 300 mm) passes on to

the main belt conveyor, the oversized materials are removed, both mechanically and manually. The

constituents segregated at this stage are suitably disposed off.

The MSW after inspection is fed into a de-dusting cum pre-drying system to remove dust/sand/earth

(10 mm particle size) in a Fines Separation Rotary Screen in which hot air is injected. After the fines

separation, MSW is fed into another Rotary Screen to classify the material into two fractions: Over

size + 150 mm and undersize –150 mm.

Undersize fraction (- 150 mm) will primarily contain organic matter and is directly fed through a belt

conveyor in to the Rotary Dryer. The oversize fraction (+ 150 mm) is fed into a Primary Shredder

through a Magnetic Separator (to separate ferrous material) to reduce its size to - 150 mm. The

output from the Primary Shredder is then fed into Rotary Dryer.

In the Rotary Dryer, the material is dried by using Hot Air generated in a fixed grate in a specially

designed Hot Air Generator (HAG), in which woody biomass segregated from MSW is combusted.

The output from the Rotary Dryer is then fed into the Rotary Trommel to separate the fines through 8

mm screen.

After the screening, the material is subjected to Air Classification in a specially designed Air Density

Separator, in which the lighter components are entrained in the air and collected separately. The

heavy material such as stones, glass falls through the classifier and is separated as Inert. These inert

are then taken to a separate site where its constituents are further manually separated. The light

fraction thus separated comprises biomass, paper, textiles and other combustible material and is

termed as Refuse Derived Fuel (RDF) Fluff, having an average GCV of 2,800 kcal/kg.

The RDF fluff will be available for firing in the specially designed boilers to generate high pressure /

high temperature steam. The steam generated from the boilers is utilized in turbo-generator to

generate 20.9 MW power and exported at 11 kV level.

The turbine is designed for the operation with the inlet steam parameters at 41 ata and 410 °C. For

Turbine, provision is made for uncontrolled extraction steam at 6.5 ata. The balance of the steam

supplied to the turbine flows through the LP section of the turbine into the surface condenser at a

pressure of 0.1 ata.

MSW Management in processing units & landfills of BBMP areas

Terrafirma Biotechnologies:

Terra-Firma Biotechnologies Ltd (TFBL) has established solid waste recycling facility –I and II based at Bangalore Since 1994 in an area of total 130 Acres to process 650 MT per day of MSW generated in Bangalore. Later in 2008, BBMP signed an agreement with TFBL, to supply 1000 MT of MSW to their processing yards for a period of 30 years from the date. TFBL has invested Rs 32.50 crore in 2008, to set up the integrated solid waste recycling facility (after enhancing their capacity to 1000 MTPD) at Gundlahalli, Doddaballapur.

Some of the major observations and salient features of the TFBL are listed below

Until last year, BBMP was transporting around 650 Mt to 1000 MT and MSW processing was smooth. Recently, following protests after the closure of Mandur & other landfill, the TFBL, Gundlahalli has been overburdened by the additional pressure of garbage loads. During the study period, it is handling an estimated quantity of 1,200 MT of MSW per day.

The facility includes composting, bioreactor landfill and biomethanation treatment units with a designed treatment capacity of 465, 285 and 250 TPD respectively with an allied biogas based captive power plant. Apart from it also has plastic-to-RDF and bricks units.

Since 2008, TFBL has been supplying compost to farmers of surrounding villages and also has tie-up with fertilizer companies and KCDC with their brand named products.

TFBL is generating biogas (from bio-methanation), after the segregation of wet waste from their incoming MSW. The biogas is used in their engines to generate power, which has been consumed internally for 3-4 hours during unscheduled load-shedding.

Recyclic of plastic and others with blended additives to manufacture the pipes Final disposal of waste materials to scientific landfill site, followed by extraction of land fill gas

from land fill site at regular intervals.

Karnataka Compost Development Corporation (KCDC):

Karnataka Compost Development Corporation (KCDC) was established in 1975 as one among thirteen MSW to compost plants in India based on World Health Organizations technology as per the directions of Government of India to 22 States in accordance with the recommendation of Shri Sivaraman Committee constituted on the subject. KCDC is floated by Karnataka Agro Industries Corporation, BBMP and Karnataka State Co-operative Marketing Federation Limited with 51%, 24.5% and 24.5% shares respectively.

This is the only plant running successfully unlike other twelve plants, which closed down their operations within one year due to unsuitability of technology to Indian un-segregated garbage conditions and lack of economic viability.

KCDC plant set up in 15.1 acres, is presently processing 200 MT segregated MSW per day by compost method and it will be increased to 500 MTPD after its expansion program over 30 acre. MSW yields 13-15 % compost, rejects are being dumped in adjacent area of the composting unit. KCDC is planning to integrate RDF unit, during their capacity enhancement of 500 MTPD. KCDC is producing city compost – (175 MTPD), and vermi- compost (15 MTPD) granulated organic manure in KCDC Brand name Agri Gold (15-20 MTPD) by blending organic additives. The majority of their products are sold to Dept of agriculture and tied-up fertilizer companies.

MSGP, Doddaballapur.

In October 2014, MSGP Infratech Pvt. Ltd. has established the MSW processing plant of 500 MTPD capacity, over 15 acres of land at Chigarenahalli, Doddaballapur. At present, 500 -600 MT of MSW per day is supplied by BBMP to the site, which are segregated manually & using machineries (trommels). Then the biodegradable waste will be subjected for composting and separate provisions are made for leachate handling & it is used to hasten the composting process. Waste such as plastic, glass and metals are recycled and the remaining waste is converted into RDF unit, which is proposed for installation. The yield of ~12% is obtained during composting of MSW for 21 days. Presently MSGP is selling their bagged compost to local farmers of surrounding villages.

New Processing Plants - BBMP

In the past few years, forced closure of landfills and inadequate operations of earlier MSW processing units in BBMP had resulted in huge amounts of unprocessed garbage lying in various parts of the city, leading to environmental problems. After the High Court direction to BBMP for not dumping any more garbage the way it has been, the state government had planned to establish six new MSW processing units in different locations of the BBMP areas.

The plants were expected to handle around 1,800 tonnes of MSW per day and Karnataka Urban Infrastructure Development and Finance Corporation (KIUDFC) was nominated as the nodal agency for implementing the project. An amount of `440 crore has been invested for the project.

BBMP have set up six new plants at the following locations:

1) Kannahalli - 500 TPD

2) Subbarayappanapalya – 200 TPD 3) Seegehalli - 200 TPD

4) Doddabidarakallu - 200 TPD

5) Chikkanagamangala – 500 TPD 6) Lingaderenahalli - 200 TPD


Appendix – 5/2

Sheet 1 of 7


It was observed that each plant has adopted more or less similar (Composting & RDF) technology and MSW is being transported by BBMP to the new plants on trial basis. So far, each plant is receiving only 100 to 150 MT of MSW at their plant premises and it is expected to take at least 2-3 months for these plants to process waste at their maximum potential. To ensure reliable operation of these six MSW processing units, operators with previous experience of successfully running MSW plants were been selected through tendering process. Payment agreement with the operators was made on the basis of support fee to be paid for the by-products, which the processing units will generate.

The new plants are linked to the different zones of BBMP, to minimise transportation cost and also waste from the respective zones will feed to the processing units. In order to ensure smooth running of these units, the government has ordered escrow accounts to be opened (maintained by BBMP) and the support fee to be paid for the by-products, which the processing units will generate.

The six plants, which are catering one of essential service for BBMP, will be closely monitored to ensure that they function as per the required objectives and environmental regulations. Detailed action plan has been drawn for periodic maintenance, regular up-gradation and troubleshooting problems.

Kannahalli - Bruhat Bangalore Hotels association (BBHA)

The BBMP had asked the bulk generators, especially hotels to establish a plant for scientific management of MSW generated by their hotels in BBMP limits. For the same, Bruhat Bangalore Hotels association (BBHA) had signed a MoU with BBMP and Noble Exchange Environment Solutions (NEX) with requisition for BBMP to provide suitable land for the waste processing unit. Based on that, BBHA had appointed NEX to design, build and operate a 250 TPD food waste – Compressed Bio Gas (CBG) processing plant in 5 acres land at Kannahalli, Magadi road.

At present the plant has started its operations handling only 8-10 MTPD, which is very low, compared to their installed capacity. Making the unit nearly defunct, the investment made to the same is questionable. It was known that the BBHA is citing reasons of cost burdening of MSW collection, transportation of pre-segregated organic waste from their institutional customers.

Maltose Agri- products – Doddaballapura

Maltose Agri Products Pvt Ltd (MAPPL), in collaboration with private firm Carbon Masters India Pvt

Ltd, had recently established a waste-to-energy plant in Huskur, Doddaballapur. The compressed

biogas bottling was developed with the support of the MNRE and the project was backed by BBMP

and BBHA. Plant will process the wet waste for 21 days and produce biogas that are bottled after


Appendix – 5/2

Sheet 1 of 7


purification. It was known that, MAPPL have tied up with around 300 hotels and restaurants located

in north and east Bangalore, for supply of the biodegradable waste to be processed at their plant. The

plant, set up at an estimated cost of Rs 2.5 crore, is capable of processing ~20 MT of MSW per day.

Compressed biogases are either sold to hotels and industrial users.

Mavallipura

In earlier years, some quantity of Bangalore waste was openly dumped in Mavallipura landfill, Later in 2004, BBMP had signed an agreement with M/s Ramky Infrastructure Limited, for setting up a compost unit of 600 MTPD of Bangalore MSW over 100 acres of land at Mavallipura. Due to various issues such as land possession and huge quantity of garbage supply as against the agreement, M/s Ramky was not able to process the waste scientifically at the 300 MTPD processing unit, and received a strict KSPCB notice to close down the facility.

Public Interest Litigation was filed in high court of Karnataka, from public and environmental activists. Garbage crisis in 2012 had forced the BBMP to stop transportation of MSW to Mavallipura, after the high court of Karnataka issued temporary stay and planned for treating the existing waste through bioremediation process.

In 2013, expert committee recommended considering the proposal of BBMP & M/s Ramky Energy and Environment Ltd to establish waste-to-energy plant without revising tipping fee and restricting the concession period to 20 years as per the original agreement. Payment to M/s Ramky was based on the compost products and % of inert that goes to Landfill. However the project did not take off.

In July 17, 2014, Karnataka High Court directed BBMP to reopen the existing processing unit in Mavallipura, and transport upto 300 MTPD of segregated wet waste to be composted, as it was one of the options for scientifically management of MSW in Bangalore.

S. Bingipura.

BBMP has owned 20 acres of land at S. Bingipura¸ the abandoned quarry with 400-500 ft deep was designated to be a landfill for debris, but later it was used as dumping yard. Around 500 -1000 MT of waste generated from Bangalore South zone were transported by 120-140 trucks on daily basis, until Bingipura residents have resorted to protests for dumping the garbage in their area.

Recently, fires breaking out of the garbage accumulation led to methane formation over the years. BBMP has promised that it’ll stop the dumping at Bingipura once the processing unit at Chikka Nagamangala will be ready. Mud-capping will be undertaken soon to control the stench emanating & convert the 20-acre dumpyard into park with provision for drinking water pipes to the local people.

Lakshmipura Landfill

Since 2012, BBMP was transporting 250 MTPD of mixed MSW from Bangalore and dumping to an abandoned quarry spread over 8 acres at Lakshmipura village, near Bannerghatta. A few months ago, the dumping was stopped due to non-compliance of MSW Rules (2000) by BBMP. It was known that ~70 % in the dump yard was organic waste, which was not supposed to dump in landfill sites. Recently, fire broke out because of methane gas continuing to leak out from the dump yard.

Mandur.

Mandur, a small village situated in Bangalore East Taluk, had two landfills - Mandur North and South - measuring up to 135 acres. Since November 2014, BBMP ended garbage dumping at Mandur landfills after the Karnataka High Court ordered BBMP & clean up the waste lying at the dump in the next two years.

Prior to November 2014, on an average, 400-450 loaded trucks were dumping an estimated amount of 2,000-2,250 tonnes of garbage (or half of Bengaluru’s MSW) daily at Mandur. For processing of the same, BBMP had hired two private companies, Organic Waste India Private Limited, a biomining and composting firm, had a pilot project operational in one part of the landfill, while the other part has Srinivas Gayathri Resource Recovery Limited (SGRRL).

Srinivas Gayathri Resource Recovery Ltd (SGRRL) – Mandur South

SGRRL got the approval from KREDL to set up Waste to Energy plant at Mandur on October 14th, 2005. SGRRL had entered into an agreement with BBMP as public-private partnership initiative to generate power of 8 MW from 1,000 MT of MSW per day and will sell the power to state grid. The company had received all approvals from various agencies and obtained term loan assistance from a consortium of banks.

During our visit to SGRRL, Mandur we observed that only few equipments & machineries of the power plant were erected and there was no signs of completion of the work to commence its operations. The reasons for delay in the process were not known, as there was no contact person from SGRRL available, neither on their plant premises nor website.


Appendix – 5/2

Sheet 1 of 7


From the discussion it was known that, BBMP served a notice to the SGRRL asking them to commission the plant by December 2013. But the firm continued to occupy the land, with no significant progress of the WtE plant, even after many deadlines had passed for its completion. KSPCB noted the firm supposed to scientifically process the garbage at Mandur and also failed to set up a power plant till date, as stipulated in the contract (2005) with BBMP. In this regard, BBMP has terminated the contract entered with SGRRL, as the firm has appropriated huge sum for processing fees and borrowed Rs.90 crore by mortgaging the BBMP land allotted to it. Organic Waste India Pvt Limited (OWIPL) - Mandur North.

Organic Waste India Pvt Limited had set up a 300 MTPD compost facility at Mandur and started its operations from July 2013. It was known from OWIPL that, since inception, BBMP had supplied ~4000 MT of MSW to the compost unit and about 1500 MT of organic material were recovered after processing the same.

However, OWIPL had proposed for setting up WtE project that will process 1000 TPD of mixed MSW to generate 8.2 MW of power at Mandur. Firm had signed the agreements with BBMP for an operating period of 35 years. BBMP had allotted 25 acres at Mandur, and firm was waiting for the site clearance of the existing garbage dump to construct the WtE plant at estimated capital of Rs. 150 crores. Due to the stoppage of MSW transportation to the Mandur, following the High Court Direction, the BBMP has made provision for allotting the land to OWIPL at some other location of Bengaluru.

During our visit to the Mandur, the sheds constructed for “composting” the “segregated waste” were not operational. OWIPL had mentioned that BBMP had vocally agreed for the biomining of existing dump at Mandur.

M K Aromatics –

M K Aromatic, Chennai based company had been awarded tender by BBMP, to set up a plant in Bengaluru to convert post-consumer waste plastics into crude oil. After the getting approvals from various departments, the firm is intending to setup a conversion plant of 10 MT capacity over 5 acre land in Bengaluru. The investment is estimated to be 10 crores paying a 2% royalty every month to BBMP. Firm will make their distinctive arrangements to collect plastic material across the city. Pyrolysis technology will be adopted for the waste plastic and needs no drying or cleaning prior to crude oil production. Crude oil can be used to run machines and vehicles.

Giddenahalli – Essel Infra Ltd.

In May 2014, BBMP had signed agreement with M/s Essel Infra projects Limited to set up an integrated waste management unit at Kannahalli on Magadi Road. Plant is intended to process 600 MT of MSW every day on 20 acres of Giddenhalli (BBMP) land and produce 8 MW of power. It is expected to be operational by December 2015 .

Satarem - Gorur halli, Solur Satarem Enterprises Pvt. Ltd had proposed project “Bangalore Alternate Fuel and Energy (BAFE) from MSW” in the Global investors meet 2013. The project intended to process 1,000 tonnes of garbage every day and produces 14.5 power. It was known that, thereafter received various approvals from concerned departments to establish WtE plant in Gorur Halli, Solur of BBMP limits. But the project has not been able to initiate due to stiff resistance from the protesters.
