Toxics-driven projects occupy about 17% of the programme portfolio. The focus of the projects comprises studying the impacts of toxic effluent discharge by industry, inorganic agricultural practices and municipal waste generated by humans.
Some of our recently completed toxics related projects and their final reports are given below.
The coastal area of Karachi receives 472,000m3 domestic and industrial wastewater primarily through Lyari and Malir River and from streams and drainages. Continued disposal of the industrial and domestic waste in to Arabian Sea causes fish to die and reduces marine life in coastal waters and the valuable export of shrimps.
The project was implemented to estimate the level of heavy metals in seawater at hotspot sites at the Karachi and Gwadar coastal area and to determine the amount of heavy metals in the marine sediments and biota of the coastal areas. The study provides a baseline for the impact assessment of disposal of industrial and municipal wastes in the coastal environment.
The main objective to launch this project was purposed to resolve the problem of solid waste management in four abadies of Gujranwala.
Solid waste management techniques were effectively introduced/ demonstrated and included waste separation, collection, disposal, recycling and composting for organic fertilizer. During the project organic and inorganic waste materials were separated and the organic material was converted into organic fertilizer with the BM technology.
The main aim of the project was to present a workable model of organic farming to the farmers of Depalpur in Okara. Farmers were made aware and were introduced to biological methods of farming as safe alternatives to chemical and pesticide use. Four trainings and workshops were organised for local farmers on indigenous practices. The slurry from biogas plants was used as organic fertilizer. Organic pesticides from ‘Neem’ were also found effective. Currently only a few motivated farmers are practicing organic farming in the region. Providing on-hand training on earthworm cultivation and composting was also part of the project plan. Although a model farm with earthworm hatchery and compost pits was established for demonstration, earthworm cultivation was not successful due to the unavailability of the required earthworm species in Pakistan.
