Abstract — Waste is an unnecessary input to or any undesirable output from any system comprising of all types of resources. Waste management is those activities required to manage waste from its final disposal process. These include amongst process such as collection, transport, treatment and disposal of waste and monitoring. It encompasses regulatory and the legal framework that related to waste management encompassing guidance on recycling. The amount of waste generated by humans was insignificant due to low population density and societal levels of the exploitation of natural resources. Some Common waste produced during premodern times was mainly ashes and human biodegradable waste and these were released back into the ground locally with …show more content…
Waste is not something that should be disposed of with no regard for future use. It can be a valuable resource if addressed correctly through policy and practice. With rational and consistent waste management practices.

Waste management (WM) is one of the major environmental problems of Indian cities as well as other countries also. Improper management of solid waste (MSW) causes hazards to inhabitants etc. MSW is disposed of unscientifically in open dumps and landfills, creating problems to the environment and public health. Waste management usually relates to all kinds of waste whether generated during the extraction of raw materials the processing of raw materials into intermediate and final products or human activities including sewage, hazardous, agriculture, wastes and municipal. Waste management is extends to reduce adverse effects of wastes on health. Waste Management practices are not uniform among countries, regions and industrial, residental sectors. Waste management is all those activities and action required to manage waste from its inception to its final disposal. This includes amongst other things, collection, transport, treatment and disposal of waste

B. Functional Classification of Waste Management
Above all WM types in the first goal we can generate the operation which is main process for control the wastes and manage the plan for reducing wastes and in second process based on reduce the waste, how we can reduce the waste, have different methods are used and what type of benefits to the industry and other waste are available and in next step we collect the material, machine, men, money, methods for, to manage the waste in that field, after collection of all type of data we gone for next step and main step of waste control is used which is recycle here all worker are used for individual material of individual type and then here less material dispose after recycle and control the waste material. An effective waste management at the quick identification of the waste generated, reduction, collection, handling, optimal reuse and recycling and effective disposal of waste management problems. Waste management can functionally classified into five common elements such as
1. Generation 2. Reduction 3. Collection 4. Recycling 5. Disposal

Each waste stream shall be treated as a potential health hazard. Excessive exposure to these waste streams must be reduced to the lowest possible level by using appropriate
Solid waste is normally collected in a solid waste area equipped with compartments or containers for each type of waste.
Waste management is the operation of how waste materials are handled. The affair of waste management is relevant to everyone world-wide. Wastes are materials that have no further economic use, and when disposed of, are hazardous to humans and the environment. Wastes include solid waste, liquid wastes, and air pollutants created by humans and cannot be naturally recycled. Current waste management techniques need to be completely overhauled because funding in government budget is not enough to meet standards, landfills are reaching their maximum capacity worldwide, and nuclear waste storage must be handled correctly. Waste management has been a highly thought about complication for global authorities. Due to
Many people hold on to the belief that recycling is unnecessary, and even among those
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.
The raw materials are then sent to the production shop to be processed in large containers and under certain conditions for product manufacturing. At this stage of the production cycle, high amounts of energy and water are consumed and wastes are generated. Most of the companies in the industry are aiming to reduce the consumption of energy and water, and production of waste with their sustainability programmes and
The advantages influenced the team to choose this method as a potential solution to the waste management issue affecting Sadhikhola. Some advantages are:
The waste management of a manufacturing company is one of the environmental matters that is mostly concerned by the society. The costs to manage the wastes from production could be very costly to a manufacturing company. Nevertheless, by using ABC system, a company can manage the production wastes in an effective and efficient manner. ABC system provides a road map to the cost reductions on waste management (Joseph & Thomas, 1995). It provides the activity-based information for the management to make better business decisions around sustainability and profit. An example would be Safety-Kleen corporation, a waste-recycling company who wanted to find an alternative to removing and recycle the hazardous wastes at a cost efficient way. It introduced ABC system into its organisation and successfully save costs in its waste management operation. The activity of transfer wastes from the collection points to the vehicles and to the disposal sites can be traced by the ABC system (Joseph & Thomas, 1995). In this way, ABC system helps to facilitate the cost measurement and provides management with accurate cost information of each activity involved in the process to make optimal decisions. Hence, with the utilisation of ABC system, it would help an organisation to have better cost control and management to support its sustainability interests on environmental
A. Recycling is the recovery of useful materials such as paper, glass, plastic and metals from the municipal solid waste stream to use to make new products, reducing the amount of virgin raw materials needed. (http://www.epa.gov/waste/nonhaz/municipal - I plan to cite on PP)
Waste management is obtained through: mapping the process, using the DMAIC methodology to address each identified waste and then using Lean
• Organize and conduct information, education and communication ( IEC ) activities on integrated Solid Waste Management Program such as recycling, Re-use, composting, sanitation, proper collection and disposal of solid.
Traditional methods of waste disposal have proven to be ineffective and have caused harmful effects on the environment. The most popular and inexpensive way to get rid of garbage is burial, but burying your problems does not necessarily mean getting rid of them. Landfill sites pose as severe ecological threats as these mass garbage dump yards overflow with trash and frequently contaminate our air, soil and water with hazardous wastes. About 400 million tons of hazardous wastes are generated each year1. A large-scale release of these materials can cause thousands of deaths and may poison the environment for many years. For example many industrial companies around the world cannot afford to enforce the strict pollution regulations set by many developed countries. This usually forces these types of companies to move to developing countries where pollution regulations are very lenient. These developing countries knowingly accept environmentally hazardous companies usually because they are in desperate need of employment. The harmful effects of these companies were clearly illustrated in the 1960s and 1970s when residents living near Minamata Bay, Japan, developed nervous disorders, tremors, and paralysis in a mysterious epidemic. The root was later found to be a local industry that had released mercury, a highly toxic element, into Minamata Bay. The disaster had claimed the lives of 400 people1. Since 1970 you can bet that a lot more than 400 people have died as a result of waste disposal. If the type of waste disposal were cheaper and effective we wouldn’t have to deal with waste problems, which still plague mankind today.
Further, “In 2008, nearly 13 tonnes of waste were generated by Canadian households. Of this, more than 8.5 million tonnes were disposed of in landfills or incine...
Efficient waste managing approaches help with reducing and avoiding unpleasant impact on the environment and human health, while allowing financial development and progress in the quality of people’s life. People do not even imagine what is the size and capacity of their activities and the impact they produce on the environment. Garbage is an important ecological problem. It is seems amazing that approximately all of the citizens of the world identify rubbish as a major environmental problem and yet these people still litter. According to the Environmental Protection Agency (2008), an American produces 250 million tons of garbage per year (para.2). There are different circumstances that are based on the society, environmental conditions, occupation and size of each of the different family. As Richmond (2010) stated, if no administration organizations has the responsibility or resources to concentrate their efforts on the waste disposal, then the responsibility to do that is on ...
Wastes are the products of our consumptions in our daily life routines such as lunch, work, school and other things we do. Little things such as throwing out a piece of paper, we are producing waste by the seconds. After we consume a product we usually throw out what’s left that can’t be consumed any further. Results in producing waste, substance that are born after it’s been use or consume by us. At the end of each day we throw out a bag full of garbage, all of the materials in that bag (paper towels, cans, leftover foods and many other material’s) all of these are waste. Hospitals produce medical waste such as use needles for treating patients. Corporations produce papers, plastics, tires, steels, cans and many other type of solid waste which contribute to the pollutions that cause health risk and other environmental issues.
