2.4 Size of the Project & Associated Activities

The Proposed IMSWMF comprises of processing units like receiving yard, Compost Plant, Recycling yard and Secured landfill for catering the BBN Area. The proposed project is designed to handle the present municipal waste along with future increased quantity depending on the population growth of the area.

2.4.1 Land

The proposed project is coming up in an identified municipal dump area by Municipal Authorities and the site will be cleared to certain extent and will be developed in planned manner so that it can be used for further few decades. Details of land break up for present and for catering future needs are given in Table 2.1.

2.4.2 Manpower Requirement

The details of the skilled and unskilled manpower required for the proposed project during construction and operation is given in Table 2.2.

2.4.3 Water Requirement

The water requirement for the proposed facility will be met through the Groundwater / bore wells within the boundary limits of the proposed project. The detailed breakup for various activities is given in Table 2.3.

2.4.4 Power & Fuel Requirement

The details of the power and fuel required for running DG sets for emergency use during power failure are given in Table 2.4.

2.5 Technology and Process Description

The activities planned in the proposed project includes collection, transportation, treatment & disposal of municipal solid waste in compliance to the MSW Handling Rules (2000). The basic concept for the solid waste management of the BBNDA project area is presented in the form of the flow chart in s Figure 2.7. This concept has been developed keeping into considerations the following design criteria, for the design period of 15 years.  Compliance to the MSW handling rules (2000) for waste collection, transportation, treatment & disposal;

 Providing Door to door collection of waste from source in segregated manner with the introduction of 2-bin system (for green waste and dry waste);  Introduction of an efficient secondary waste collection & transportation system using refuse collectors etc;

 Adapting the 4Rs principal of waste minimization through reduction, reuse, recycle and recover. Hence, proposed a mechanism for recovery of recyclables at the processing facility and waste reuse through composting of food waste and other green waste;

 Final disposal of only rejects/inerts at the scientifically developed landfill with an
attempt to dispose not more than 25% of the generated waste quantity at the landfill.

The municipal waste received at the site is processed at waste management facility by segregating the waste into recyclable and composting material. After separation of recyclables the compostable material will be diverted to compost plant. The detailed material balance flow diagram for processing of MSW is described in Figure 2.8. The list of the important major machinery, vehicles, sheds; etc required for the proposed project is given in Table 2.3

2.5 Compost Plant

The compost plant is based on the concept of open windrow aerobic composting of organic (biodegradable) component of solid waste. All activities associated with composting operations need careful selection of design and control to produce good quality product while minimizing environmental impacts. Activities which should be considered for composting include,

 Transportation of raw material/feed
 Raw material handling
 Windrowing of the waste material
 Weekly turning
 Screening, Sorting, Grinding, Blending & Mixing
 Curing, Storage & Packing

2.6.1 Composting Process

Aerobic composting is the process of degradation of biodegradable waste matter into simple organic compounds by certain micro organisms in the presence of air. The process begins at ambient temperature by the activity of mesophilic bacteria which oxidize carbon to CO

, thus liberating...
