Palm oil production a source of heat-trapping methane

are a climate concern, CU-Boulder study says
In recent years, palm oil production has come under fire from environmentalists concerned about the deforestation of land in the tropics to make way for new palm plantations. Now there is a new reason to be concerned about palm oil’s environmental impact, according to researchers at the University of Colorado Boulder.
An analysis published Feb. 26 in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. But the researchers also present a possible solution: capturing the methane and using it as a renewable energy source.
The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22,000 passenger vehicles in the United States, the analysis found. This year, global methane emissions from palm oil wastewater are expected to equal 30 percent of all fossil fuel emissions from Indonesia, where widespread deforestation for palm oil production has endangered orangutans.
“This is a largely overlooked dimension of palm oil’s environmental problems,” said lead author Philip Taylor, a postdoctoral researcher at CU-Boulder’s Institute of Arctic and Alpine Research (INSTAAR). “The industry has become a poster child for agriculture’s downsides, but capturing wastewater methane leaks for energy would be a step in the right direction.”
The global demand for palm oil has spiked in recent years as processed food manufacturers have sought an alternative to trans fats.
For now, the carbon footprint of cutting down forests to make way for palm plantations dwarfs the greenhouse gases coming from the wastewater lagoons. But while deforestation is expected to slow as the focus shifts to more intensive agriculture on existing plantations, the emissions from wastewater lagoons will continue unabated as long as palm oil is produced, the researchers said.
However, the climate impact of the leaking methane could be mitigated by capturing the gas and using it to fuel power plants. Biogas technology has been used successfully for decades and it can produce renewable electricity at a cost that’s competitive with traditional fuels, the authors said.
The amount of methane biogas that went uncollected from palm oil wastewater lagoons last year alone could have met a quarter of Malaysia’s electricity needs. Tapping into that unused fuel supply could yield both financial and environmental benefits, the authors said.
Capturing methane at wastewater lagoons could be encouraged by making it a requirement before palm oil products can be certified as sustainable, the authors said. Current sustainability certifications do not address wastewater emissions.
Taylor, whose research typically focuses on carbon cycling in old-growth tropical forests, was inspired to do the analysis by undergraduate researcher Hana Fancher, who also is a co-author of the journal article. Fancher and Taylor were doing research in Costa Rica, where palm oil production is spreading, when Fancher became curious about how the oil was being processed.
“She has a wastewater background,” Taylor said. “She ended up doing an honors thesis on palm oil agriculture and wastewater emissions. This paper is an extension of that thinking.”
Other co-authors from CU-Boulder include Associate Professor Diana Nemergut, doctoral student Samantha Weintraub and Professor Alan Townsend, in whose lab the work was based. Other co-authors include Cory Cleveland of the University of Montana, William Wieder of the National Center for Atmospheric Research and Teresa Bilinski of St. Edwards University.

Food replacement available to those receiving assistance
Sep 17th
Federal program allows replacement of food lost due to flooding
Boulder County, Colo. – The federal program that provides food assistance to those who qualify for it will replace food lost due to the recent flooding in Boulder County. The replacement funds are available to those who are currently receiving food assistance, and covers food purchased using September Food Assistance benefits.
The recent severe flooding has cut off many Boulder County residents’ access to their food supplies, and in some cases has led to the spoilage or destruction of food. Those who purchased some of their food through the Supplemental Nutrition Assistance Program (SNAP) during the month of September and have now lost some of it due to the flooding may fill out an affidavit requesting replacement of the funds.
“It’s difficult enough to get the food and other help you need during a disaster like this,” said Larraine Archuleta, director of the Community Support Division of the Boulder County Department of Housing and Human Services (BCDHHS). “We want to be sure those who qualify for these replacement benefits have every opportunity to receive them.”
The value of the food assistance replacement will be based on the purchases made in September through the SNAP program.
Residents who feel they may qualify for the replacement food assistance should contact BCDHHS’ Community Support Manager Lynn Grey at lgrey@bouldercounty.org or 303-441-1000. Those seeking the replacement will need to sign an affidavit, which can be done via email, mail, or in person at one of the BCDHHS locations in Boulder or Longmont once they have been contact by Lynn Grey.

No more geeky hardware in the trash or go to jail

Many Electronics will be Prohibited from Trash Bins Starting July 1
The Electronic Recycling Jobs Act bans electronics from landfills
Boulder County, Colo. – Effective July 1, Boulder County residents can no longer place computers and many other types of electronics at the curb, or in waste bins, for collection and disposal. The Electronic Recycling Jobs Act, signed by Governor Hickenlooper in April of 2012, intends many benefits for the state including job creation through material recovery, diversion of hazardous material from landfills and reduction of energy and raw material resource demands from mining and manufacturing.
Banned devices include:
- television sets
- central processing units (CPUs)
- computer monitors
- peripherals
- printers
- fax machines
- laptops
- notebooks
- ultra books
- net books
- electronic tablets
- digital video disc players
- video cassette recorders
- video display devices with a screen greater than four inches
The law requires that consumers deliver their electronic equipment to collection facilities or collection events. Boulder County will no longer accept waste electronics at the Nederland or Allenspark transfer stations or county recycling drop off centers. Residents of Nederland and Allenspark can expect county-organized collection events on or around Labor Day weekend.
Electronic devices contain a number of hazardous elements that can migrate if disposed in a landfill, potentially contaminating groundwater and soil. Brokers and recyclers with an e-Steward or R2 certification have demonstrated that they meet specific environmental standards and safely manage used electronics. Residents of Boulder County can find a list of certified electronics recyclers and local collection events atwww.bouldercounty.org/env/recycle/pages/ewaste.aspx.
