Solid Waste Management
Solid waste being generated from the Korangi tannery cluster is about 117 tons/day on an average basis. It contains dusted salt, raw trimmings, fleshing, wet blue trimmings, shavings,buffing dust etc.
The waste was thrown in the waste bins constructed at the various locations in Sector 7-A. PTA managed a system comprising of tractors and trolleys to dispose the waste from bins to a near by dumping site. The existing system did not address segregation of wastes at sources, proper transportation, reuse/recycling issues and safe disposal. In order to improve the condition a comprehensive Solid Waste Management Plan (SWMP) was required. – Low capital and energy costs.
Thus, scope of SWMP was defined as the designing of an efficient system for management of solid waste in an individual unit and also at the cluster level. The program focused on
To evaluate the existing practices for waste collection and to develop more effective alternate options to reuse and/or final disposal of solid waste taking into account for technical, environmental, organizational and financial aspects. - To assess the current situation and the environmental impact of the different options.
To establish the requirements of environmental protection for the disposal of solid waste.
To establish the design criteria of the different options.
Design the recommended option including organizational aspects of solid waste collection, reuse and disposal system.
Goals
The overall objective of the solid waste management program was to minimize the adverse environmental affects caused by the indiscriminate disposal of solid wastes, especially of the hazardous wastes.
Activities
Following activities were executed to establish a proper SWMP
1.Assessment of the existing situation of solid waste generation and the current disposal .
2.A quantitative and qualitative analyses of the solid waste.
3.The design of the system for segregation of the solid waste within the tanneries.
4.Feasibility for the collection, transportation and disposal facilities for solid wastes.
5.Identification and selection of suitable dumping sites.
6.Identification and selection of suitable machinery and equipment for collection and.
7.Review of different technologies for re-use and then selection of appropriate technology.
8.Preparation of financial feasibility for reuse options
9. Preparation of implementation strategy.
10.Initiation of Implementation.
