(i) Location of site

R.s.No- Balaganoor Road Gadag

 (ii) Name of waste processing technology

Windrow composting & Engineered land filling.

The methods as adopted in the state policy on management of municipal solid waste and as per the guidelines of DMA are being adopted, a brief description of which is given below.

Windrow composting (Not yet started)

The daily Waste is dumped on the windrow platform, formed into windrow heaps of approximately 2.5m wide and 2m height. Aerobic Microbial culture is sprayed on the waste and to provide air and to control moisture the heaps are turned once in a week. The waste is let to decompose for a period of 28-30 days, during which the entire organic component is decomposed to form compost manure. Then the waste is fed to screening equipment to separate the compost from the inert non-degradable matter.

Engineered land filling (Started)

The waste is filled in engineered land filling pit of 7m wide X 2.5m depth X 50m long pits, compacted by rolling tractor over it, thereby forming a daily cell. Anaerobic microbial culture is sprayed and covered with little quantity of local soil. The process is repeated until entire pit is filled. Usually compost is formed within a period of 2-3 months. The entire waste dumped into the pit is then re-excavated and the compost is screened by the compost screening equipment.

(Note: Engineered land filling is started since 1-12- 2010 and manure is sent to KSPCB for analysis.)

Compost screening plant (Cost - 2 lakh):

The mixed waste containing compost and other inert matter is fed to the screening equipment where the organic manure is separated from inert materials.

(Note: Process of purchasing a compost screening equipment is under progress.)

  (iv)  (iv) Quantity of waste being processed per day

70.0 Tons

    (v) (v)Details of agreement between municipal authority and operating agency

Operated by municipal authority.

(vi) (  (vi) Utilization programme for waste processed (product utilization)

The organic compost formed by the aforesaid method is proposed to be sold to farmers for agricultural purposes.

(vii)    (vii) Methodology for disposal of waste processing rejects (Quantity and Quality)

After the separation of compost, it is approximated that the waste processing rejects constitute about 40% of the total waste. This comprises of a variety of mixed materials such as plastics, metal, glass, ceramics, etc.

Right now during engineered landfilling activity large size inerts are being picked up and stored separately. It is proposed to retrieve as much as possible recyclable plastics and recyclable material from the rejects. It is proposed to dispose the final/ ultimate rejects which are unusable in permanent sanitary landfill.

(vii)    (viii) Measures to be taken for prevention and control of environmental pollution 

• The Windrow platform is a firmly constructed RCC platform which evidently prevents percolation of leachate.
• The platform is surrounded by leachate collection drains which is routed to a leachate collection tank.
• It is proposed to pump and reutilize leachate from leachate collection tank for windrow composting, thereby reducing pollution loads.
• The base of the engineered land filling pit is covered with stone slabs to prevent infiltration of leachate.

 (ix)   (ix) Investment on project

132.56 lakhs

(x)   ( x) Measures to be taken for safety of workers working in the plant

• The workers engaged for waste processing activity are provided with respirators, hand gloves (both rubber and nitrile type), gum shoes.
• To avoid direct contact during segregation of rejects the workers are provided with punjas etc.
• To handle bulk waste during processing the ULB has its own Tractor-mounted Loader with Backhoe.
• Also, all the transport vehicles have tipping mechanism to avoid multiple handling of waste.

Disposal of waste

  (i)    (i) Quantity of waste to be disposed per day

Approx. 1 MT of inerts

   (ii   (ii) Nature and composition of waste

Biodegradables : 44.76 %

Plastic : 0.62 %

Glass/ Ceramics : 0.44 %

Metal : 0.64 %

Stones / ashes : 41.81 %

Miscellaneous : 11.73 %

(iii)    (iii) Details of methodology or criteria followed for site selection

As stipulated in MSW rules, 2000 and with consent from Karnataka State Pollution Control Board.

          (iv) Details of existing site under operation

• The site is 2 km away from the town.
• The site bears red soil.
• The underground water table is well below the surface.
• The site is surrounded by agricultural lands
• There are no lakes, rivers or any other water bodies near the site.
• There are no monuments of historical importance near the site.

          (v) Methodology and operational details of land filling

As per the state policy and guidelines from the Directorate of municipal administration, it is proposed at first to practice the engineered landfillng method which will be progressively developed to sanitary landfill.

Sanitary Land filling:

The sanitary landfill will be designed for a life span of 5-10 years. A large size pit will be formed and the base will be laid with a clay layer of permeability not exceeding 10^-7 cm/sec. Thereafter geo-membrane will be placed over it, on top of which again a clay layer is paved. Leachate drainage layer will be formed to collect the leachate.

The final rejects from the waste processing and segregation plant are filled in the sanitary landfill in the form of daily cells.

After completely filling the waste again a layer of geo-membrane, clay liners are placed over the entire surface of the landfill. Finally, it is covered with local soil and perennial plants are grown to form a final vegetative layer.

           (vi) Measures taken to check environmental pollution

Overall, all the measures given in the MSW rules are adopted to check environmental pollution.

To monitor under ground water contamination, analytical colorimetric water testing kits are being purchased. Tender is already invited and work order to be issued soon.

         (vii) Man power at landfill site

Proposal for hiring the services of an operator for Tractor-mounted Loader with Backhoe and 3 labours for waste segregation, culture spraying and equipment operation has been sent to DUDC for approval. Approval is awaited.
