Bangladesh is a developing country and now it is facing a huge number of growing unmanageable population bomb. A significant number of the population is being migrated from countryside to urban cities each year. This migration is creating unplanned urbanization and mushrooming of slum that produces a lot of unmanageable solid waste in all major cities of Bangladesh.
More over as a typical developing country, Bangladesh is experienced with mushrooming factories, tanneries and industries in the industrial areas and other unconventional areas; are contributing a significant amount of solid waste. Thus we need proper solid waste management with associated facilities and strict ...view middle of the document...
But this report is not free from shortcomings. While preparing this report I faced some problems. These are as follows:
2.Limited data regarding waste management as in Chittagong there is only one recycling plant;
3.Communication problem as the plant is in a backward place;
I, therefore, hope that the study will be judged considering the above-mentioned shortcomings.
Solid waste management concept
Solid waste can be defined as material that no longer has any value to the person who is responsible for it, and is not intended to be discharged through a pipe. It does not normally include human excreta. It is generated by domestic, commercial, industrial, healthcare, agricultural and mineral extraction activities and accumulates in streets and public places. The words “garbage”, “trash”, “refuse” and “rubbish” are used to refer to some forms of solid waste.
Solid waste management is the collection, transport, processing (waste treatment), recycling or disposal of waste materials, usually ones produced by human activity, in an effort to reduce their effect on human health or local amenity. A subfocus in recent decades has been to reduce waste materials' effect on the natural world and the environment and to recover resources from them.
Recycling means to recover for other use a material that would otherwise be considered waste. The popular meaning of ‘recycling’ in most developed countries has come to refer to the widespread collection and reuse of various everyday waste materials. They are collected and sorted into common groups, so that the raw materials from these items can be used again (recycled).
In developed countries, the most common consumer items recycled include aluminium beverage cans, steel, food and aerosol cans, HDPE and PET plastic bottles, glass bottles and jars, paperboard cartons, newspapers, magazines, and cardboard. Other types of plastic (PVC, LDPE, PP, and PS) are also recyclable, although not as commonly collected. These items are usually composed of a single type of material, making them relatively easy to recycle into new products.
In many areas, material for recycling is collected separately from general waste, with dedicated bins and collection vehicles. Other waste management processes recover these materials from general waste streams. This usually results in greater levels of recovery than separate collections of consumer-separated beverage containers, but are more complex and expensive.
