Environment: Waste production must peak this century. The now-full Jardim Gramacho landfill in Rio de Janeiro, Brazil, received more than 10,000 tonnes of waste per day.
Solid waste — the stuff we send down our chutes, discard at work and put on the curb every week — is a striking by-product of civilization. The average person in the United States throws away their body weight in rubbish every month. When waste management works well, we give it little thought: out of sight and, usually, quickly out of mind. Discarded materials are collected, some are recycled or composted, and most are landfilled or incinerated. But the global view is troubling. Waste disposal facts, information, pictures.

Waste management is the handling of discarded materials. Recycling and composting, which transform waste into useful products, are forms of waste management. The management of waste also includes disposal, such as landfilling. Waste can be almost anything, including food, leaves, newspapers, bottles, construction debris, chemicals from a factory, candy wrappers, disposable diapers, old cars, or radioactive materials. People have always produced waste, but as industry and technology have evolved and the human population has grown, waste management has become increasingly complex. Why is nuclear waste bad? Nuclear waste. Nuclear waste is produced at every stage of the nuclear fuel cycle, from uranium mining and enrichment, to reactor operation and the reprocessing of spent nuclear fuel.
Much of this nuclear waste will remain hazardous for hundreds of thousands of years, leaving a poisonous legacy to future generations. Nuclear waste is often just dumped with little thought to safe storage. Criminal Probe Launched After Toxic Chemical Spill at Colorado Air Force Base. Get short URL Both the Air Force Office of Special Investigations and the US Environmental Protection Agency are investigating the improper discharge, which was discovered on October 12.
Officials have stated that the chemicals ended up in the wastewater treatment system, but did not make it into the city’s drinking water supply. The water was contaminated with perfluorinated compounds, or PFCs, which is used the firefighting foam used on military bases. What has the U.S. government been hiding about the Fukushima nuclear disaster? A massive ongoing gas leak in southern California is being compared to the 2011 Fukushima disaster.
A recently declassified US government report found that the Fukushima catastrophe was far worse than had been originally reported, prompting many to wonder how severe the California gas leak really is. Methane, a greenhouse gas 70 times stronger than carbon dioxide, has been spewing into the air from a natural storage gas site in southern California for almost two months, and it isn’t expected to be fixed until this spring. The Deathly Effects of E-Waste. Trashing our old electronics could be putting millions of people at risk.

According to a recent report by the BBC, e-waste pollution is causing severe health concerns for millions of people around the world, mostly in the developing nations of Africa, Europe and Asia.
