TechnoSanity #31: A look at Waste Management and landfill gas energy resources

The other day talking with a friend I noticed a Waste Management trash truck roll by and had this sudden reflection "I own a piece of that truck". I own a few shares of WM's stock, hence I "own" a tiny fraction of the truck that rolled by. She was surprised and asked "you don't do socially responsible investing, then?" While I try to select companies with socially responsible thinking my investments are not SRI pure. Take that for whatever it is worth, the stereotype attached to Waste Management is they're an evil corporation just doing the worst thing possible with the trash we throw away while painting their trucks green to pretend they are environmental stewards. Greenwashing, in other words. Turns out that stereotype isn't entirely accurate.

Turns out that Waste Management has a bunch of environmental information on their web site. While putting brochures on a web site doesn't fix the environment it shows they are at least thinking about it and recognizant of their role in environmental stewardship. I don't know how well they do as environmental stewards. However it's clear they have the potential to play a large role due to their position of receiving all the trash people throw out. That trash is potentially a resource stream which can be turned into products.

It's not just Waste Management but every "trash" company in the world, if there were technology whereby they could perform recycling on a huge scale of every item that comes into their hands it would perhaps erase the word "landfill" from our vocabulary. Unfortunately that potential isn't anywhere near being implementable. One small piece to the puzzle is the "landfill gas" that lots of waste companies, Waste Management included, is looking at tapping. This gas is a form of natural gas and can be burned just as natural gas, and being a biogas has some positive environmental benefit over fossil natural gas. It can also be liquified into a fuel to use in trucks.

On November 2, 2009, Waste Management and the Linde Group announced a project at the Altamont Landfill (near Livermore CA) which makes liquified natural gas from landfill gas, the LNG will be used to power Waste Management's trucks. They believe the plant has the capacity to produce 13,000 gallons of fuel per day, from that one plant. Given that it's from just one of Waste Management's landfills, it's mind boggling to think of the quantity of landfill gas emitted from all landfills around the country (or around the world), and how much fuel that represents.

Energy production from landfill gas turns out to be a big deal. Yahoogling for "landfill gas renewable energy" turns up lots of interesting articles and resources. The following is just a smattering of what I found.

The landfill-to-energy process begins with garbage collected and brought to landfill operations. Much of it is organic and is broken down by bacteria in a natural process. Methane and other gasses known as landfill gas is produced. With special wells the gas is captured and piped to a processing facility.
After processing it is the same as natural gas and can be used the same way.

Each landfill gas "well" is just a couple pipes drilled into the ground.

Waste Management Partnering to Find Gas in the Trash: This project at the Altamont Landfill is only one of many which Waste Management plans to launch. They own 477 landfills and have announced intent to open 60 landfill gas projects by the end of 2012. Further there are 1,700 operating landfills in the U.S., and according to the the EPA’s Landfill Methane Outreach Program, they contain enough natural gas to produce 2,643 megawatts of electricity.

CARB tables of landfill gas composition shows the percentages of different constituents to landfill gas. On average it's 44% methane and 35% CO2, both are recognized as the leading components to greenhouse gas.

Clearly averting the emission of those gasses into the atmosphere would abate some greenhouse gas issues. However burning the landfill gas doesn't destroy the carbon. Therefore burning landfill gas cannot avert emission of the landfill gas. What it can do is replace the use of some fossil natural gas or fossil liquid fuels.

Production of 25 MW of Electricity Using Landfill Gas: Describes a project in Montreal (Canada) to build an electricity plant that uses landfill gas as its fuel. The plant cost CAD $37 million to build and produces 25 megawatts of power.

Video: Powering Up with Landfill Gas: Discusses a similar project at the University of New Hampshire. In the video it's mentioned they've been "flaring" their landfill gas, and are now instead using it to generate power. Flaring gas just means they're burning it with no attempt to capture any energy. Turning it from a flaring to power production situation is an improvement by any measure.

Waste-based Renewable Energy: Landfill operators place collection wells that act like straws throughout a landfill to draw out the methane gas. The gas is then piped to a compression and filtering unit beside the landfill. Technicians make sure that the gas is filtered properly before it is piped to its end user. The entire process is carefully managed to prevent odors and leakage of waste material.

California Energy Commission, Renewable Energy Research, Biomass and Landfill is a resource center about landfill gas research in California. When a landfill is capped, landfill gas (LFG) is generated as organic portions of the municipal solid wastes (MSW) are decomposed. Traditionally, landfill is not controlled and the expected period over which landfill gas will be produced may range from 50 to 100 years. But a usable landfill gas production rate that can be utilized lasts for only 10 to 15 years. A bioreactor is a controlled landfill in which water and other nutrient sources are added into the MSW to increase the landfill gas production rate.

The four basic uses of landfill gas is:

1. medium-BTU gas production, 
2. electricity generation, 
3. injection into existing natural gas pipelines, 
4. conversion to other chemical forms. California leads the nation in both the solid waste generation and number of landfill gas to electricity (LFGTE) facilities. The Puente Hills landfill, operated by the Los Angeles County Sanitation District, produces approximately 46.5 MW of power and is the largest LFGTE facility in the U.S.

US EPA Landfill Methane Outreach Program (LMOP): is a voluntary assistance and partnership program that promotes the use of landfill gas as a renewable, green energy source. Landfill gas is the natural by-product of the decomposition of solid waste in landfills and is comprised primarily of carbon dioxide and methane. By preventing emissions of methane (a powerful greenhouse gas) through the development of landfill gas energy projects, LMOP helps businesses, states, energy providers, and communities protect the environment and build a sustainable future.

Instead of allowing LFG to escape into the air, it can be captured, converted, and used as an energy source. Using LFG helps to reduce odors and other hazards associated with LFG emissions, and it helps prevent methane from migrating into the atmosphere and contributing to local smog and global climate change.

Is Landfill Gas Green Energy? Is a study by the Natural Resources Defense Council looking at just how "green" an energy can one get from landfill gas.

• Combustion of raw LFG in a flare, an engine, or a turbine dramatically reduces the overall toxicity.
• Collection and combustion dramatically reduces global warming impacts and toxicity.
• Using LFG to generate electricity further reduces the greenhouse gas impacts and also reduces emissions of nitrogen oxides, sulfur dioxide and mercury. Burying garbage in landfills results in the release of more heat-trapping gases than any other waste-management option.
• Because LFG is a by-product of landfills, and landfills are such a poor way to manage our waste, LFG can not be considered renewable.

TechnoSanity #30: Peak Oil and the UKERC Peak Oil report

In October 2009 the UK Energy Research Centre released an in-depth report on Peak Oil. In this episode of the Technosanity Podcast we go over several articles discussing the report.

Articles discussed in the podcast:-

"Global Oil Depletion" a report on Peak Oil by the UK Energy Research Centre is my summary of the report. Of especial interest is the following two charts.


This shows the rate of oil discovery over the years, and shows that the peak of oil discovery occurred in the early 1960's. The lack of discovering oil is not due to a lack of searching, it is due to a lack of finding. The lack of finding new significant oil discoveries implies strongly that the fossil oil resources on this planet have all been tapped out.



The important wedges in this chart are "Crude oil - fields yet to be developed" and "Crude oil - fields yet to be found". Looking at the chart it appears the IEA expects on the order of 40 million barrels/day will come from those two sources. The first, fields yet to be developed, is oil that's known to exist but hasn't had infrastructure installed to extract the oil. The fields yet to be developed require extensive investment to install that infrastructure.

The fields yet to be found simply aren't known yet. Where are they? We don't know. The IEA is putting a lot of credence in the wish or hope or expectation that those fields will be found. Maybe they'll be found, maybe not.

There needs to be a long lead time to install the infrastructure - something like 10 years to build out an oil field full of oil derricks etc.

• Peak Oil - It's Still Coming, It May Be Delayed Though,
• Whither Resilience and Transition? Why ‘Peak Oil’ Has Yet to Outlive its Usefulness,
• Oil production could peak in 10 years' time,
• Have We Reached Peak Oil? 
• and A post-oil world gets less sci-fi by the day all go over the same UKERC study.

The UKERC study warns that the world society will have to find 64 million barrels/day in production by 2030 to replace the decrease in production they expect by then. This is shown on the above chart. But it's not clear where that oil will come from.

Canadian tar sands? The Canadians doubt they'll ever get more than 3 million barrels/day in production.

There are four key issues about oil production and which together point to a supply crunch sooner rather than later.

• declining output: That's peak oil, once we're past the global oil peak it means oil production is declining
• declining discoveries: Discoveries have been in a decline since the early 60's, it means discoveries do not match the rate of use, and that we're due to run out no matter what
• increasing demand: Population increases and other factors mean continuing demand increases
• insufficient projects in the pipeline: Without oil infrastructure projects to exploit the known fields, the oil production capacity cannot increase even with fields we know about

Reflections from ASPO: Contradiction, EROI, and Future Energy Supplies is a look back at the recent conference of the Association for the Study of Peak Oil. He talks at length about Energy Return on Investment (EROI) in regard to some claims about "Shale Gas" resources. Someone claims there's 200+ years of natural gas available from Shale Gas. However what's missing from that claim is the EROI of extracting that gas, and if it requires a lot of energy to extract natural gas from shale then is it worthwhile to do so?

TechnoSanity #28: Offshore drilling on the U.S. Outer Continental Shelf, an Interior Department hearing, held in San Francisco, April 16, 2009

In the waning days of the Bush Administration they released a draft Continental Shelf 5-year program meant to cover 2010-2015. The current program runs from 2007-2012 and it's curious that there's an overlap. The overlap means that the Bush Administration sped up the 5-year planning process by a couple years. Under the normal schedule the next 5-year plan would have covered the years 2012-2017. To support putting the new plan together the Department of the Interior is holding a series of public hearings, and the following is based on the San Francisco hearing on April 16, 2009.

At stake is oil and gas drilling in the Outer Continental Shelf. You may recall a slogan in the 2008 Presidential Election was "Drill Baby Drill, Drill Here, Drill Now" as if drilling for more oil is what will solve the energy woes faced by the U.S. The U.S. is importing nearly 70% of the oil we use and of course the money spent on that oil undermines the U.S. economy (balance of trade), and is a national security matter (the oil rich countries have power over the U.S.). The Conservative Republican answer is to drill for oil. However anybody who's looked at the data realizes there is very little oil involved, and that it will take decades before the oil can come to market.

It's clear the attendees were overwhelmingly taking a different attitude about the problem. Over and over the presenters and question askers gave a different strategy than "Drill Now, Drill Here". Instead they overwhelmingly opposed drilling for new oil, and advocated instead use of renewable energy. Rather than spend the money on oil drilling rigs etc, spend the money on new technologies.

It's clear that a big event in their mind is the Santa Barbara oil spill in the 1960's. That oil spill put an image in everybody's mind of spoiled beaches, dead birds, etc. FWIW The attendees were overwhelmingly Californians.

The NIMBY aspect of this strikes me. California cities are overwhelmingly designed around the use of CARS and TRUCKS to move around the cities. Overwhelmingly those vehicles require fossil fuels to move around. Hence that oil has to come from somewhere and to deny the possibility of drilling for oil off the California coast means pushing the oil infrastructure fueling California's cars is conducted in someone else's back yard.

At least most of them advocated tying a shift to renewable energy resources combined with a ban on further oil drilling. Tying the two together is more honest than simply denying further oil drilling. However for the most part renewable energy resources are not in the forum of liquid fuels, but in the form of electricity. To continue supporting transportation systems through a renewable fuel is going to mean electrically driven transportation.

Some data presented.. while big oil spills are thankfully rare, there are small spills all the time. It's estimated there are 2 million gallons per year of small oil spills.

Offshore drilling comes with higher risk of disasters. The further offshore the bigger the risk. Off the Pacific coast the oil fields thought to exist are in deep water, and there are doubts over the possibility to safely drill in those deep waters. Further oil drilling causes the release of mercury and other contaminants, simply from the drilling platform.

One of the proposed locations is in an ocean upwelling zone off the Northern California Coast. Upwelling zones are vital places of abundant sea life where upward ocean currents carry nutrients to the surface feeding an abundant array of life. Allowing oil drilling to occur in that upwelling zone would convert it into a dead zone.

A draft proposal has been produced by the government outlining the plan: Draft Proposed Outer Continental Shelf (OCS) Oil and Gas Leasing Program 2010–2015

Technosanity #26: Interview w/ Don Amador at 24 Hours of Electricross

Continued coverage of the 24 Hours of Electricross race, continuing from Technosanity #25: 24 Hours of Electricross - Interview with Neal Saiki. Don Amador is with the Blue Ribbon Coalition, an organization specializing with taking off-highway vehicles (OHV) into the wilderness (mission: "The BlueRibbon Coalition champions responsible use of public lands and waters for the benefit of all recreationists by educating and empowering its members").

He attended the race to measure noise levels to understand the potential for electric off-highway vehicles to address noise issues related to OHV use. With a noise meter he recorded the race as producing 60-67 dB whereas normal motorcycle races produce noise in the 100+ dB range. At 65dB it is the same as regular conversation between people.

Electric vehicles offer more than mitigating environmental damage from burning fossil fuels, and they offer more than a way out of the peak oil mess. They offer a solution to noise pollution in our cities.

After 100+ years of gasoline vehicle use our society has become immunized to the noise coming from them. But they are noisy even if we're not aware of that noise. Think of the potential change to the quality of our cities if there were a preponderance of electric vehicles.

Technosanity #25: 24 Hours of Electricross - Interview with Neal Saiki

On April 4-5, 2009, Zero Motorcycles held the 24 Hours of Electricross race. This was an endurance race for their brand of electric motorcycle, 24 hours in length, 10 teams, three battery packs per team, the winner being the team achieving the most number of laps during that period. I've never been to a dirt bike race, never ridden a "dirt bike" style motorcycle "on dirt", but am an electric vehicle enthusiast and was excited to see this race occur.

I've been to the NEDRA race, the National Electric Drag Racing Association has a goal, shared by Zero Motorcycles, of proving that electric cars aren't boring golf carts. Electric vehicle races are a great way to show electric vehicles can be fast. However the NEDRA race is in the form of a drag race, 1/4 mile, 10-15 seconds, and that's it. The Electricross race just kept going and going and going. What made this possible is a motorcycle frame design which allows for quickly changing the battery pack. I observed several times a racer would come in off the track, the pit crew quickly change out the pack, and within a minute or so the bike is back on the track (with a new rider).

Quick change battery packs are not a new idea. Famously this is a key of the Project Better Place plan, however the idea is very old and goes back to the earliest days of electric vehicles. Zero Motorcycles have simply done a great job of implementing this old idea.
