2.1 TYPES OF SOLID WASTE
Solid waste can be categorized into different types:
1.Municipal Waste
2.Hazardous Waste
3.Bio Medical Waste
2.1.1 Municipal waste
The term municipal solid waste (MSW) is mostly used to describe most of the non-hazardous solid waste from a city, town or village that requires routine collection and transport to a processing or disposal site, Sources of Municipal waste include private homes, commercial establishments and institutions, as well as industrial facilities.
In 1947 cities and towns in India generated an estimated 6 million tonnes of solid waste, in 1997 it was about 48 million tonnes. More than 25% of the municipal solid waste is not collected at all; 70% of the Indian cities lack adequate capacity to transport

In smaller towns trucks having 5–9 ton capacity are used without adequate cover system. Stationary compactors, mobile compactors/closed tempos, and tarpaulin- covered vehicles are used in the transportation of MSW and about 65, 15, and 20% of waste is transported through these compacters, respectively. The maintenance of vehicles used in for transportation of waste is usually done in workshop run by ULBs but most of these workshops can do minor repairs only. No wonder, in the event of breakdown of these vehicles, the overall collection, transportation, and disposal efficiency reduces drastically. Only few transfer stations can be found in some metropolitan e.g. Mumbai (Joseph, …show more content…
Land required for open compost plants is relatively large. Also, issues of methane emission, smell, and flies from badly managed open properly carried out there is possibility of toxic material entering the stream of SOLID WASTE.
2.2 VERMI-COMPOSTING :-
Vermicompost (or vermi-compost) is the product of the composting process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast.
Vermicompost contains water-soluble nutrients and is an excellent, nutrient-rich organic fertilizer and soil conditioner. It is used in farming and small scale sustainable, organic farming.
Vermicast (also called worm castings, worm humus or worm manure) is the end-product of the breakdown of organic matter by an earthworm. These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting.
Vermicomposting can also be applied for treatment of sewage
The collected solid waste is delivered to one of three solid waste facilities (Kwajalein, Meck, or Roi-Namur) by the solid waste division or by individual departments. Although incineration and landfilling activities occur on Roi-Namur and Meck Islands, the Kwajalein Solid Waste Management Facility is the central receiving area for the majority of solid wastes generated. Waste reduction and waste minimization at USAG-KA is primarily focused on reducing the volume of solid waste generated and increase solid waste diversion to prevent potentially useful material from being thrown
In elementary school, we are taught by our teachers that fruit peels can be composted to recycle nutrients back into the soil where they came from. Composting food scraps is not a new idea by any means, but what if it was to be expanded into something much bigger? Recently, a study outlining the environmental impact of recycling digested food waste in comparison to that of chemical fertilizer was published by the Swedish University of Agricultural Sciences. In the experiment, the scientists found that currently, the two were relatively equal in terms of general environmental impact, and that in order for the food waste fertilizer to prevail, further enhancements will have to be made to
Harmful emissions from the landfills escape into the air we breathe. The soil and water are also contaminated from our
Composted cow manure makes garden plants grow great. It has rich strong fertilizer. Usually it is mixed in with the soil or put on top of the dirt. Sometimes if the fertilizer is too limited it cannot make the right amount of heat to get enough nutrients. Although if it is too big, it can't get air very well. In order to give the manure air, you have to turn the pile a lot.
What is Vermicomposting Vermicomposting is worm composting, it’s a great way to recycle your carrot peelings, eggshells, coffee grinds, and used paper towels. Red wiggler worms can eat their body weight in food each day. As they eat, the worms create castings that are nutrient-rich organic matter. When castings mix with decomposed organic matter, you wind up with compost full of beneficial microbes and nutrients that, when spread in a garden, help feed, nourish, and protect growing plants. According to a 1998 article in Bio-resource Technology, vermicompost is compared with high-grade horticultural compost "has desirable aesthetics, has reduced levels of contaminants and tends to hold more nutrients over a longer period, without impacting the environment.
Solid waste management, the compilation, managing, and disposing of solid items that are neglected because they have failed to function or are no longer effective. Incorrect removal of municipal solid waste can create contaminated conditions, and these conditions in turn can lead to corruption of the surroundings and to outbreaks of vector-borne disease—that is, diseases caused by animals and insects. The tasks of solid waste management present complicated technical obstacles. The local government is responsible for collecting reusable, recyclable and non-biodegradable waste materials from the material recovery facilities and transporting them to the recycling centers and or to the municipal material recovery facility.
... Studies have shown that the presence of pathogens in a final compost may contaminate the food chain with the incomplete compost product provoking the growth of pathogenic microbes or keeping them alive and vigorous. Most notably, human pathogens like Aeromonas, Aspergillus fumigatus, A. terreus, Cryptosporidium and Giardia cysts, Enterococcus faecalis, Geotrichum candidum, GeoBacillus stearothermophilus, G. thermoglucosidasi, Klebsiella, Listeria monocytogenes, Pseudomonas, Saccharomonospora and Saccharopolyspora, Salmonella typhimurium, Shigella, Thermoactinomyces, Thermobifida, and Bacillus sp. being thermophilic and sporulating species still persist in a variety of compost. Studies are going on to give a better and ultimate solution view on the parameters for the eradication of various pathogenic strains activated or evolved during the process of composting.
Compost is an easy solution to eliminating the waste that our environment brings, while at the same time, providing many benefits to us, and the environment. By using compost, it improves our plant growth by enriching the soil that it drinks its nutrients from. It helps us avoid buying soil amendments such as peat, bark mulch and bagged manure. Compost also loosens the heavy clay that is in our soil, while improving the capacity to hold water and adding essential nutrients.
wage and productive work to agriculturists consistently. Poultry compost has high fertilizer esteem and can be utilized for expanding yield of all products.
Also, when soil in and close production ranges turn out to be unclean due to dumping of excess material, such terrestrial cannot be used for farming processes. Pollution is also caused by iron and steel mills; zinc, lead, and copper smelters; municipal incinerators; oil refineries; cement plants; and nitric and sulphuric acid plants. Soil pollution is mostly due to elements in herbicides (wild plant killers) and pesticides (toxins which kill flies and other invertebrate mice). Litter is unused material put in public places such as streets, parks, picnic areas and near shops. The addition of waste intimidates the wellbeing of individuals in housing areas. Waste decays, heartens domestic rascals and goes urban places into unappealing, unclean and unhealthy areas to live in.( (Michael
chemicals. In order to avoid polluting the water we spread the manure and slurry when
Policy is needed to regulate which course of action should be taken and how it should be implemented. Because of this, many plans and policies revolving around the management of solid waste have been put in place. Sometimes however, a particular policy can have its shortfalls, potentially resulting in its negative aspects outweighing the positive ones. According to the Conference Board of Canada Report, “Canadians dispose of more municipal solid waste per capita than any other country” (2013). Solid waste management in particular, involves many aspects, ranging from packaging waste, food waste, etc. (White & Franke 1999), hence, the following analysis revolves around household and commercial waste – referred to as Municipal Solid Waste (White & Franke. 1999) – in the Greater Vancouver Regional District. Municipal waste is a major health and environmental concern as it contributes to numerous problems like habitat destruction, surface groundwater pollution, and other forms of air, soil, and water contamination. Waste disposal methods like incineration create toxic substances, and landfills emit methane, which contributes to global warming. According to the Zero Waste Objective Report, “The impact of climate change and the increasing awareness of the role of “waste” and “wasting” in the production of greenhouse gas emissions is a constant environmental pressure… (2009). This leads to an increasing limitation of government to prevent and control the volume and toxicity of products in the waste stream and a growing need to shift responsibility to the product manufacturer.
Due to the fact that there is a huge problem with garbage disposal, government representatives must contribute to resolving this issue. Efficient waste management approaches help with reducing and avoiding unpleasant impacts on the environment and human health, while allowing for financial development and progress in the quality of people’s lives. People do not even imagine the size and capacity of their activities and the impact they produce on the environment. Garbage is an important ecological problem. It seems amazing that approximately all of the citizens of the world identify rubbish as a major environmental problem and yet these people still litter.
Solid waste can be classified in different types, depending on their source, household waste is generally classified as municipal waste; industrial waste as hazardous waste or hospital waste as infections waste. It quite obvious that South Africa environment is deteriorated by the illegal dumping area that around here. Solid waste is a major problem this country is facing at the moment. The province that is experience this major problem is Gauteng province, this an urban area am taking about, and since it’s clear that over population is the cause of the problem. Gauteng province is an over populated than rural area .solid waste pollution is refuse or garbage that people use in their everyday life in their house, such as plastic
The solid wastes are produce not only by households; it’s contributed by hospitals and corporations. Hospitals throw away bandages, use needles and latex gloves, these items hospitals throw away daily all the time because they can’t be reuse for the safety of its patients. Corporations throw away a lot of waste as well such as papers that they use whether in writing or in projects. All of these leftovers after consumptions are waste that is produced by our daily actions.
