Urban solid waste consists of household waste, construction and demolition debris, sanitation residues, industrial and hospital waste. Industrial and hospital waste are considered to be hazardous wastes as they may contain infections and toxic agents.
Solid Waste Management (SWM) practices have broadly the following components; generation, storage of waste at source, segregation of waste at source, primary collection, temporary storage, transportation of waste and treatment and / or disposal of waste.
As per Tenth Five Year Plan 2002-07, India produces about 42 million tons of urban solid waste annually. The per capita waste generation varies between 0.2 kg. to 0.6 kg. per day, and the current municipal solid waste generation is estimated to be approximately 0.4 kg per capita per day.
It has been estimated that because of the increasing per capita waste generation of about 1.3 per cent per year, and the growth of urban population of between 3 and 3.5 per cent per annum, the yearly increase in the overall quantity of solid waste in the cities is about 5 per cent. Urban waste management by the ULBs is already under stress because of poor resources and inadequacies of the City Development Plan for Dehri-Dalmianagar Intercontinental Consultants & Technocrats Pvt. Ltd. Unless concerted efforts are made to improve the flow of resources to solid waste management and build up systems which incorporate the basic requirements of a proper waste management practice, the problem of urban waste will be further aggravated and cause environmental health problems.
In Dehri, approximately 35.89 tons of garbage is being generated every day. Solid waste management in Dehri is in very poor state and is performed by DNP at present.
Presently the waste is not segregated at the household level. The residents dump the waste in the nearby collection points or on the nearest vacant land.
The sources of solid waste generation in Dehri include:
The waste generated at these places is broadly categorized as organic and inorganic waste. There is a marked variation in the biodegradable component of MSW in accordance with the land use pattern. Industrial areas are considered to generate relatively less amount of biodegradable waste while residential areas, local fruits /vegetable markets, institutional areas and public / semi-public areas within municipal limits generate waste with high biodegradable component. Industrial and hospital waste are considered to be hazardous wastes as they may contain infections and toxic agents. The recyclable constituent includes paper, plastic, glass crockery, clothes, metal, etc. Paper, plastic and rag contributed a major fraction while glass, metal contributed to a lesser extent.
