Waste management strategy:
The entire strategy should be geared towards “Shrinking of the Kachra Kundis”. I.e. fewer and fewer items should enter the garbage dumps. This can only be done if the principal of separation at source is applied. When less and less wastage will have to be removed there will naturally be a saving of vehicles, their petrol and their maintenance.
- Children’s pampers are one of the biggest hurdles and these must be discouraged.
- Shopping bags should not be thrown around indiscriminately
- Garbage burning should be stopped forthright
- Fresh and sweet water should not be used in lawns gardens, parks and nurseries. Gutter water should be used instead.
- Factory effluents should not be allowed to enter rivers and seas.
Livestock from wet garbage:
The media especially the Sindhi media, KTN and Sindh T.V must explain to the people the importance of organic waste to agriculture and animal husbandry. It should be explained to the people that religion forbids waste and even the vegetable waste should be handled with care. I.e. either given to livestock or used for organic fertilizer. Wet garbage should not be thrown on cemented ground. Instead it should be thrown on unpaved land without plastic bags. Sites should be reserved in the cities especially for grazing of livestock called “Chara Ghar”. Over here separated vegetable and fruit peals may be collected on plastic sheets to keep them in good condition. Every town must have a “Chara Ghar” where lambs and sheep may come to graze. Here there must be enclosures of some kind where each animal may be charged for grazing. These charges would help in the overall maintenance of the enclosure. Timings of the enclosure should be between 6:00 a.m and 8:00 p.m. Livestock raring may be inextricably connected with the organic waste that is coming out of the cities and which is more than 50% of the total waste.
New items in wastage are being introduced frequently. Thanks to rapid industrialization. Cottage industries and informal sectors have become very innovative as far as recycling goes. “Machar Colony” and “Godara Colony” are two places where a good deal of the city’s wastage is being collected, bought and sold. The “Machar Colony” deals with shopping bags while “Godara Colony” deals with all kings of textiles. An information pool may be made to show what kind of wastage is being bought and sold. Linkage between waste management and cottage industry can be improved with the introduction of research workers from different discipline of science and arts.
Gul Bahao has succeeded in making building blocks and pre-fabricated housing from shopping bags and other industrial waste. The housing industry and others could learn from this research which will have a deep impact on both environment and construction industry.
Factory effluents may be used to grow biomass or trees. Apart from dilution, chemicals may be put into them to neutralize their toxicity. Since the wood will not be used for eating purposes there will not be any danger to human beings even if the wood contains high levels of toxic substances.
Research workers and academicians from the universities and colleges must be encouraged to conduct research work on different aspects of waste management and utilization.
