PepsiCo Figures Tropicana's Carbon Footprint - NYTimes.com

Citrus groves use a lot of nitrogen fertilizer, which requires natural gas to make and can turn into a potent greenhouse gas when it is spread on fields.

PepsiCo finally came up with a number: the equivalent of 3.75 pounds of carbon dioxide are emitted to the atmosphere for each half-gallon carton of orange juice.

Nuclear-Age Archaeology

Slashdot | Oldest Weapons-grade Plutonium Found In Dump

Researchers have just identified the first batch of weapons-grade plutonium ever made. The batch was produced as part of the Manhattan Project, but predates Trinity — the first nuclear weapon test — by seven months. It was unearthed in a waste pit at Hanford, Washington, inside a beaten up old safe.

Update: More nuclear archaeology - trucker creates accurate replica of the first atom bomb.

Mexican film star in Tabasco

Mexican film star Hugo Stiglitz will visit Tabasco to scout locations for a film and work with tourism authorities to promote the southern part of the state.

'Me invitó el presidente municipal de Tenosique, para que vayamos a conocer la región, yo ya conozco desde hace muchos años, pero querían que yo fuera otra vez, para que hiciéramos un programa de Turismo y ecología para la zona de Usumacinta y toda la zona del sur del estado', indicó Stiglitz.

He's particularly interested in legends and traditions of Tenosique, including the dance of the Pochos and a tale called "El Duende de la selva", the ghost (monster, dwarf, goblin) of the jungle.

A 42 year-old lawyer and another man, 30 years-old, apparently threw grape juice, oil and some salty substances on 27 out of 33 statues in the La Venta Park in Villahermosa, Tabasco, Mexico. They claimed they were performing a prehispanic ritual. The statues are now stained and discolored, and authorities are devising a cleaning and restoration strategy.

E-Waste

We recycled a number of old computers and printers yesterday in an event sponsored by Tekserve and the Lower East Side Ecology Center. I trust those folks to choose recyclers wisely but I certainly did not check where it was all going.

Slashdot | The Scope of US E-Waste

Update: from the LESEC website FAQ:

What happens to the computers that people bring to this event?
Computer equipment dropped off during our events is loaded into trucks and transported by the our contracted electronics recycling company (Sims Recycling Solutions) to their facility. At the recycling facility all information from the hard drive is erased and the equipment is evaluated and tested for reuse potential. Electronics are then de-manufactured into component parts and recycled. Certain easily reusable components such as memory chips get harvested for reuse or refurbished for resale.

De-manufacturing involves separating equipment into 4 major categories:
1) Plastic
2) Circuit boards
3) Cathode ray tubes (CRT*) glass
4) Scrap metal

Plastic and scrap metal go to respective recyclers. Circuit boards and CRT glass go to metal/lead smelters.

*(A cathode ray tube – CRT – is the video display component of TV’s & monitors, which has lead added to the glass to protect the user from x-rays generated in the CRT)

Is any of the recycled material sent overseas?
No. We share your concern about dumping electronic waste on develping countries. Therefore we require that our vendors recycle all collected materials in the US and provide us with documentation about their down stream vendors. We audit this information to confirm validity.
