Solid waste is the term used to describe non-liquid waste materials arising from domestic, trade, commercial, agricultural, industrial activities and from public services. Waste management is a global environmental issue which concerns about a very significant problem in today’s world. There is a considerable amount of disposal of waste without proper segregation which has lead to both economical and environmental sufferings. It is better to segregate the waste at the initial stages when it is generated, rather than going for a later option which is inconvenient and expensive. There has to be appropriate planning for proper waste management by means of analysis of the waste situation of the area. Solid waste management can be bifurcated into mainly two phases. One is the waste management in the area where it is generated and second is the management of waste at dumping grounds. This includes the issues related to the waste generation, their storage, collection and removal from the collection points. There are many drawbacks in the existing Waste Management System. For ex, Allocation of waste bins at improper location, Multiple and manual handling of the waste, No separate bins for recyclable waste, Pollution of natural water streams due to waste bin proximity.
The waste management issues are considered to solve some of the present situation problems like proper allocation and relocation of waste bins, check for unsuitability and proximity convenience due to waste bin to the users, proposal of recyclable waste bins for the required areas and future suggestions. Geographical Information System can be used as a decision support tool for planning waste management.
Manual methods adopted for analysis of many factors would be a lengthy and tedious work. Also there are possibilities of errors while merging the spatial and non spatial data. But in GIS, as the work is carried in layers, there are least chances of confusion or error and the system is capable enough to coordinate between spatial and non spatial data.
There are several areas where the municipal bodies are striving hard to provide best of their services for the betterment of the city. This can be achieved with the help of GIS which can handle different data forms like spatial as well attribute data simultaneously.
Solid Waste management can be handled efficiently in several ways like Identification of exact location of waste bins, either with GPS or surveys and demarcating on the base map. Secondly maintaining a record of the waste bins, identification of existing waste lifting pattern and Location of the waste dumping ground/landfill site and lastly allocating a unique number to all the waste bins so it can be easily and quickly located in case of any complaint registered or planning and maintenance and maintaining a record about the amount of waste being dumped at the landfill site.
