Waste management is the precise name for the collection, transportation, disposal or recycling and monitoring of waste. This term is assigned to the material, waste material, that is produced through human being activity. This material is managed to avoid its adverse effect over human health and environment. Most of the time, waste is managed to get resources from it. The waste to be managed includes all forms of matter i.e. gaseous, liquid, solid and radioactive matter.
The methods for the management of waste may differ for developed and developing nations. For urban and rural populations, industrial and residential areas it does differ as well. The management of waste in metropolitan and rural areas is general responsibility of the local government. While the waste that is produced by the industries is managed by the industry itself, in case it is non-hazardous.
Methods for dumping off waste:
Landfill: This method involves burying off the waste and this is the most common practice for the disposal of waste around the Globe. These landfills are quite often conventional with deserted and vacant locations around the cities. However, not much effectively designed and older landfills can cost a big amount to the government not just in terms of money but also in the environmental and health issues. Apart from the general poorly designed landfill’s common problems like wind-blown debris and generation of liquid, it can also cause production of gas, which is extremely hazardous.
Incineration: This is the dumping off method, which involves combustion for waste materials. This sort of dumping off for waste materials through incineration and temperature is known as “thermal treatment”. This method is utilized to convert waste materials into gas, heat, ash and steam.
Incineration is conducted on both individual and industrial scale. This method is used for disposing off all sorts of matters. This generally is the most recognized practical method for disposing off perilous material. This however, is the conflict-ridden method for it causes the emission of perilous gases.
Incineration is a common practice in Japan because of scarcity of land, which facilitates through not requiring landfill for waste dumping. Two widely used terms, which are facilitating burning of waste material in furnace and boiler for generation of heat, electricity and steam, are (Waste-to-energy) WtW and (energy-from-waste)EfW.
Recycling: Recycling is the process for converting used materials into new products for the prevention of producing waste. A number of materials are included with the list for recyclable products like glass, plastic, paper, textiles, metals and electronics. The materials, which are capable for being recycled are either picked from the curbside or taken to the center, as collections. They are then sorted out and reprocessed and are given new shapes as new products. However, complex products are difficult to treat.
Biological reprocessing: Waste materials, which come in organic nature, are treated through biological reprocessing. The waste materials with organic nature are plant, food and paper products. This reprocessing or recycling of this organic matter is put to biological decomposition which later if recycled in form of mulch or compost for landscaping and agricultural purposes. Additionally, the waste gas, which is collected from the process, is used for the production of electricity. The goal behind biological reprocessing is to control and speed up the natural decomposition for organic matter. A numerous sort of composting techniques and methods for digestion are employed depending upon the requirement as if digestion is required for household heaps or industrial materials. There are diverse methods for biological reprocessing like anaerobic and aerobic techniques.
