Toxic wastes can be disposed of by depositing them in specially built landfills or by incineration, depending on their chemical type. With land disposal, waste is buried in landfills that should be “permanently” sealed to contain the waste. Landfills may be lined with clay or plastic, or waste may be encapsulated in concrete.

What is the best way to manage toxic waste?
At household level—and at the admitted risk of sounding trite—the best way of managing toxic waste is to not have any in the first place. I.e., buy only as much of a chemical product as you need so that it’s used up—and how to dispose of it becomes purely academic.
What does toxic waste mean?
Toxic waste, chemical waste material capable of causing death or injury to life. Waste is considered toxic if it is poisonous, radioactive, explosive, carcinogenic (causing cancer ), mutagenic (causing damage to chromosomes ), teratogenic (causing birth defects), or bioaccumulative (that is, increasing in concentration at the higher ends ...

How does toxic waste affect humans?
Toxic waste can harm people, animals, and plants, whether it ends up in the ground, in streams, or even in the air. Some toxins, such as mercury and lead, persist in the environment for many years and accumulate over time. Humans or wildlife often absorb these toxic substances when they eat fish or other prey.
What happens if you dump untreated waste?
Violations of the law, like dumping untreated hazardous waste on the ground or in town landfills to avoid paying the fees charged by designated waste facilities, may result in hefty fines or even jail time. Many toxic waste dumps that still pose a threat to communities are holdovers from the era prior to 1976.

These included the discovery of tons of hazardous waste dumped below a school and suburban neighborhood at upstate New York’s Love Canal and a dumping ground in northern Kentucky dubbed “ the Valley of the Drums .”.
What are the three types of toxic waste?
Toxic waste products are divided into three general categories: chemical wastes, radioactive wastes, and medical wastes . Chemical wastes, such as those that are considered corrosive, flammable, reactive (that is, chemicals that interact with others to create explosive or toxic by-products), acutely poisonous, carcinogenic, mutagenic, and teratogenic—as well as heavy metals (such as lead and mercury )—are placed in the first category. Radioactive wastes include elements and compounds that produce or absorb ionizing radiation and any material that interacts with such elements and compounds (such as the rods and water that moderate nuclear reactions in power plants). Medical wastes are a broad category, spanning the range from tissues and fluids capable of harbouring infectious disease -causing organisms to the materials and containers that hold and transfer them.
What is the practice of sitting toxic waste storage or handling facilities in minority enclaves in some countries?
In addition, the practice of siting toxic waste storage or handling facilities in minority enclaves in some countries is considered by some environmentalists to be a form of environmental racism, the disproportionate shifting of environmental hazards to people of colour.

Where is toxic waste sent?
Another approach taken to dealing with toxic waste is to send it elsewhere; much electronic waste produced in the U.S. is shipped to developing countries, risking spillages and the health of local residents, who often lack the expertise and technology to safely deal with toxic waste.
What is medical waste?
Medical wastes are a broad category, spanning the range from tissues and fluids capable of harbouring infectious disease -caus ing organisms to the materials and containers that hold and transfer them. Get a Britannica Premium subscription and gain access to exclusive content. Subscribe Now.

What are the environmental problems of e-waste?
E-waste causes serious environmental problems worldwide. Huge volumes of scrapped computers, monitors, televisions and kitchen white goods are sent to landfill, as there are almost no industry incentives to recycle or re-use. E-waste contains a lot of harmful elements: toxic metals such as arsenic, barium, beryllium, cadmium, hexavalent chromium, ...
How long does it take to recover WEEE?
However, many nations recognise this, and legislation such as the European Union’s Waste Electrical and Electronic Equipment (WEEE) Directive requires domestic collection and recovery rates of 45% within four years, 65% within seven years and bans the export of e-waste outside the EU.
What are the drawbacks of centrifuges?
The drawback is that they are energy-intensive and costly, and hen ce only economically profitable if the products are of reasonably high value.
What is e-waste recycling?
The e-waste is divided into circuit boards, plastic cases, metal frames, glass screens and so on, before being shredded and pulverised. Various methods are then used so that the distinct metallic and non-metallic materials can be individually separated.
What is the fastest growing industry in the world?
The manufacture of electrical and electronic equipment is one of the fastest growing industries in the world, fuelled by increased consumption and by the equipment’s relatively short lifespan.
Is gold reclaimed from circuit boards worth anything?
Although the metal concentrate – copper or gold reclaimed from the circuit boards, processors or memory chips for example – is marketable and suitable for re-use, the non-metallic, powdered remnant is worth little. It tends to be either dumped in landfill, creating further environmental problems, or used as industrial filler in the cement and asphalt industries. But since this residue, chiefly comprised of plastic and aluminosilicates, makes up a considerable amount of the e-waste stream, it’s essential to find a way of adding value to it. This would make the recycling process more profitable, attract more investors and decrease the amount of e-waste that ends up in landfills and incinerators, or pollutes the developing world.
