Characteristics of solid wastes Corrosive: wastes that include acids or bases that are capable of corroding metal containers Ignitability: waste that can create fires under certain condition, e.g. waste oils and solvents Reactive: the waste that are unstable in nature, they cause explosions, toxic fumes when ated . /Toxicity: waste which are harmful or fatal when ingested or absorb
Impacts on health e It helps in breeding various types of insects and infectious organisms which cause various diseases. Is in waste, such as metal cans and broken glass, can cause cuts from sharp edges, which may lead to infection Toxic substances may leach or percolate to contaminate the ground water
Burning of batteries, e-waste etc. produces dioxins, furans and polychlorinated biphenyls, which have the potential to cause various types of ailments including cancer. e Solid waste heap up on the road due to improper disposal system causing accidents.
Impacts on environment e biodegradable materials decomposed under uncontrolled and unhygienic conditions produces foul smell. They also produce toxic gases like methane. These gasses contribute to the enhanced greenhouse gas effect and climate change. toxic metals and hazardous wastes spread on land causes changes in physiochemical and biological characteristics thereby affecting productivity of soils
Large quantities of wastes can block watercourses, leading to flooding Direct dumping of untreated waste in seas, rivers and lakes had adverse on the marine plants and animals. Degrades water and soil quality o high algae population in rivers and sea is due to dumping of untreated sewage.
PREVENTIVE MEASURES Proper solid waste management have to be undertaken to ensure that it does not affect the environment and not cause health hazards to the people living there I proper segregation of waste has to be done and it should be ensured that all organic matter is kept aside for composting. Organic waste can be composted and then used as a fertilizer.
Promoting the production of goods which minimize waste generation after use. Material recycling and recovery should be increased Promoting the use of plastic recycling identification codes and labels in order to make sorting and recycling of plastic packaging easier Educating the producers, the public and people who work in the waste sector should be increased.
Promoting the use of less hazardous alternatives to hazardous chemicals during production of goods Legislation in the waste sector should be improved . Collection of hazardous waste at collection points shall be safe, secure and performed in an environmentally sound manner.
The liner protects the ground water from being contaminated due to percolation of leachate Leachate from bottom is pumped and sent for treatment When landfill is full it is covered with clay, sand, gravel and top soil to prevent seepage of water Methane produced by anaerobic decomposition is collected and burnt to produce electricity or heat. e
Disadvantages Large area is required and it will be a source of insects Pollution of the local environment (such as contamination of groundwater and/or aquifers by leakage and residual soil contamination during landfill usage) e Leads to bad odour if landfill is not properly managed Causes fire hazard due to formation of methane in wet weather
Advantages . Residue is only 20-25% of the original and can be used as clinker after treatment Requires very little space Costof transportation is not high if the incinerator is located within city limits Bafest from hygienic point of view An incinerator plant of 3000 tonnes per day capacity can generate 3MW of power.
Disadvantages Its capital and operating cost is high Operation needs skilled persons. ormation of smoke, dust and ashes needs further disposal and that may cause air pollution.
