1.1.2 Hazardous waste
Industrial and hospital waste is considered hazardous as they may contain toxic substances.
In terms of hazardous waste, something is considered toxic if it is harmful to human health when a person is exposed to the substance through inhalation, ingestion or touch.
The largest amount of hazardous waste is created in industry, in particular the petroleum and chemical industries, which produce around 70% of all hazardous waste in the United States. The most common examples of hazardous waste from industries in general include solvents used in cleaning, wastewater from petroleum refiners and ash produced from incinerators or coal-burning power plants.
Hospital waste contaminated by chemicals used in hospitals is considered hazardous. These chemicals include formaldehyde and phenols, which are used as disinfectants, and mercury, which is used in thermometers or equipment that measure blood pressure. Most hospitals in India do not have proper disposal facilities for these hazardous wastes.

However, majority of ULBs do not have appropriate action plans for execution and enactment of the MSWR (CPCB Report, 2013). Unfortunately, no city in India can claim 100% segregation of waste at dwelling unit and on an average only 70% waste collection is observed, while the remaining 30% is again mixed up and lost in the urban environment. Out of total waste collected, only 12.45% waste is scientifically processed and rest is disposed in open dumps (CPCB Report, 2013). Existing and future land requirement for disposal of MSW along with growth in population and MSW generation is shown in Figure 3. Environment friendliness, cost effectiveness, and acceptability to the local community are major attributes to achieve efficient solid waste management system. Critical examination of important parameters of MSWM practice with respect to Indian Scenario is delineated
Junkyards use compact machines that will smash a vehicle into a flat piece of metal or into a cube, then they are placed into an auto shredder. The material or residue from the shredder has various toxins in it like copper, rubber, plastic, chrome, mercury to name just a few. This material is then used to cover landfills, but recently it has been used in kilns as feedstock (renewable, biological material) used for fuel, which can potentially put these toxins into the air.
The piece of legislation that is responsible for enforcing and regulating the production of hazardous waste, its type of management and disposal methods is known as The Hazardous Waste (England and Wales)Regulations 2005. According to The Hazardous Waste (England and Wales)Regulations 2005 part 1 of the legislation it states in article 4 of the waste directive is that the waste must be disposed of in a way that doesn’t harm human health or resorting to ways which would degrade the environment such as the surrounding surface such as soil, the natural flora in the area and the local fauna of the surrounding environment.
Stan 's plan to operate a toxic waste disposal business as a sole proprietorship raises two significant concerns. As a sole proprietor, Stan will assume unlimited personal liability for all business obligations as there is no legal or practical separation between the business and the owner. Any financial obligations or legal torts would apply to the business, and also, his personal assets. Secondly, Stan, as sole proprietor, can only borrow money directly, limiting growth, and could be considered a risky investment for lenders when they assess his ability to repay the debt, and the nature of the business.
According to science, it might be proper to dispose of these substances to the environment, but it
E- waste contains many heavy metals which are highly dangerous to human health. These include cadmium, chromium, mercury and lead. Cadmium is known to cause kidney and liver dysfunction, hypertension, pulmonary edema and immune depression. Furthermore, cadmium has been identified as a potential carcinogen. Chromium can penetrate membranes with ease and cause allergic reactions as well as harm DNA. In addition, all chromium compounds are possibly carcinogenic. Mercury and its compounds are extremely toxic as they can quickly circulate in the bloods...
Hazardous waste is the waste that poses substantial or potential threats to health or the environment a hazardous waste is a waste. The properties of the hazardous waste are very dangerous and capable of harming human and as well as the environment, in order to protect the human as well as environment we have to develop a regulatory framework capable of ensuring adequate protection,
Each hospital produces daily a considerable amount of waste, and the process of management infectious waste could introduce hazards to the surrounding environment, causing additional environmental, economic, and disease burden. Small hospitals generally constitute a problem due to being either far from management sites or lack needed infrastructure even for using the minimal standards. Dumping in public water systems, leaching from landfills, or heavy use of incineration, are examples of management process that poses direct risks to the water, soil, and air.
9. What are some of the risks that hazardous waste can have on one's health?
Municipal Solid Waste Management in India falls under the public health and sanitation and hence as per the Indian Constitution is a State responsibility. This service has always been within the public domain until very recently, that the waste management services started being
The radioactive wastes are by-products of the radioactive materials of their processing or usage that often decays naturally after period of time .whoever, they contain unstable components (radioisotopes) that emit an ionizing radiation which haveenormous harmful aspects to the environment.Radioactive wastes comprise less than 1% of total toxic wastes in countries with nuclear power, so all toxic wastes need to be dealt safely.beta partials and gamma ray emitters are the most common radioactive medical wastes .but, in industry as a waste source it usually contain alpha ,beta, neutron or gamma emitters.
Hazardous waste management is defined as the collection, treatment and disposal of unwanted material that poses the threat to the environmental chemical under managed conditions. In the hazardous management system, the treatment technologies are an inevitable method for a waste management stream. Treatment process is a significant method used to minimise the amount of hazardous waste produced and recover useful products. It can be classified into chemical, physical and biological methods. One of the best ways to get rids of waste is through chemical treatment process. Chemical treatment methods mostly use different properties of chemical to alter the characteristic of hazardous element into less hazardous elements. It is usually required an
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.
As humanity develops new technology, the magnitude and severity of waste increases. When computers were developed, it widely was believed that the need for paper would be eliminated. On the contrary this was widely proven false and we are now utilizing more paper than ever. Canada is not an exception as the typical Canadian generates an average of three pounds of solid waste each day1. This alone shows what a careless species we have become- using and disposing materials without even considering the damage we are causing. With half a trillion tones of waste around the world, only 25% may be reused for a second or third time and less than 5% can be renewed limitlessly1. These facts are true only in developed countries. Since these traditional waste reduction methods have been proven inefficient, we must endorse new innovative technology to arrive at a solution.
Pollution is a massive problem that the earth faces. Pollution is the action or process of making land, water, air, etc…, dirty and not safe or suitable to use. Pollution of air, water, and soil are the most complex issues. Various types of gases and toxins that are released by industries
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.
