Green Options

One of my friends recently attended the Treasure Island Music Festival in San Francisco and texted me about their awesome green initiatives. From the show. Yes, I’m sort of a nerd for this kind of thing.

We’re all about musicians lightening their footprints around here. According to the folks at Live Earth: “A single concert event can produce as little as 9,000 kilos (close 20,000 lbs) to as much as 90,000 kilos (197,000 lbs) of solid waste in a single day.” That’s a ridiculous amount of waste and doesn’t even take into account things like CO2 emissions from concertgoers driving to the venue or indirect emissions from the food and whatnot.

The folks at Treasure Island Fest set out to do things a little differently. Not only did they have a kickass lineup that’s making me more than a little bit jealous, they implemented all sorts of impressive green initiatives. Check our their greening and sustainability statement:

Not only is VerTerra’s dinnerware all natural, it’s biodegradable and compostable, too!

The holidays are coming fast, and that means you’ve probably got some shindigs in the works! Sometimes, especially with a lengthy guest list, it’s just so much easier to use disposable dinnerware rather than deal with a mountain of dirty dishes at the end of the night. VerTerra wants you to toss those plates, bowls, and serving trays while feeling guilt-free!

In just five weeks, San Francisco residents will face fines if they fail to separate their food scraps from their aluminum cans.

My earlier blog about greenhouse gas emissions from composting generated a lot of good discussion so I am writing to respond.

• Yes, composting is certainly better than some outcomes like food scraps going into a garbage dump which does not do anything to capture the methane

• Yes, an anaerobic digester would be a very good thing to use for most waste streams.  A recent example

Composting is a really green thing to do, right? I’ve always thought so since my Grandfather taught me to do it in the early sixties. Large-scale composting is getting to be quite the rage. The City of San Francisco attracted a great deal of attention with it’s mandatory food scrap recycling program and lots of local wineries are bragging about their use of that compost to fertilize their vineyards.

I just read today about how the Langley Parish Council in England is setting up a village compost and “set an example to small villages as the UK strives to battle climate change.”  Unfortunately, I recently learned that they and San Francisco and the Napa wineries might actually be doing is contributing to climate change.

Climate change science often ends up challenging things we think we know.

Inconvenience

The idea of composting is to provide plenty of moisture and oxygen so that microbes will digest the easily available organic matter and generate a great deal of metabolic heat in the process.  What is left at the end is a sterilized source of more resistant organic matter that can enrich a soil. 

Composting

of wastes is done with very good intentions, but there is the inconvenient truth that even a very well run large-scale compost operation emits some methane.

But if you stop to think about it, as much as you intend to have oxygen available to the whole pile (aerobic conditions), there are definitely going to be micro-sites that are going to lack oxygen (anaerobic conditions) particularly when there is huge oxygen demand during the peak of the process. That is where methane gets made.

Last month, we launched our first iPhone app based on a city feed to help San Franciscans recycle 75 percent of the materials that would otherwise go to the landfill by 2010. Today, we are kicking off a new online effort (www.RecyclingMoments.org) to get us over this green goal line and help our city save resources, energy, and reduce pollution.

In San Francisco, we have led the country in creating ambitious yet achievable programs to help residents and businesses decrease the amount of waste going into our landfill. Our modern curbside program began back in the 80s with the crazy idea that people could recycle their newspapers.

This column highlights the top economic stories of the week.

Hopes for an accelerated recovery during the second half of 2009 were diminished this week as most of the economic headlines turned negative after several months of encouraging signs. Job losses exceeded economists’ expectations, with the nation’s unemployment rate now standing at a new 26-year high. More on this story here.
