In 2006
California became the first state to pass legislation that directly recognized
the occurrence of global warming. AB32, otherwise known as the Global Warming
Solutions Act, set out to proactively fight climate change by establishing a
comprehensive program to achieve a 25% reduction in greenhouse gas (GHG)
emissions by 2020, essentially returning the state to a 1990 emissions level.
While the legislation was both innovative and laudable, it was also necessary; at
that time California was the 12th largest emitter of carbon worldwide.
Carbon
dioxide (CO2) is the principal GHG in our atmosphere making up 84%
of annual emissions (EPA, 2011). However, when it comes to assessing the harm
of GHGs volume is not the best metric. That is, while methane only accounts for
9% of GHG, it is 20 times ‘better’ than carbon at trapping radiation in the
atmosphere, and thus 20 times more effective at contributing to our planet’s
gradual warming.
Just as
with other GHGs, methane can be released to the atmosphere through natural
causes but human activities such as the raising of livestock, natural gas extraction
and landfilling waste have thrown the planet’s innate cycles out of whack.
With respect
to the latter, when not properly capped landfills release approximately 60%
methane and 40% carbon dioxide. In 2000 the EPA estimated that the ~6,000
landfills across the U.S. were contributing roughly 450-650 billion cubic feet
of methane to the atmosphere per year.
Consequently,
limiting the amount of trash that ends up in landfills is an easy way to reduce
emissions, not to mention conserve valuable resources, prevent groundwater
contamination, avoid community displacement, among other benefits.
While
California currently leads the nation with a 59% recycling rate for all
materials, they want to do better. Specifically, in 2011 Governor Jerry Brown set
a goal for 75% diversion of waste from landfills by 2020. Individually, cities
of San Francisco and Los Angeles have set even more aggressive goals of zero
waste.
This is
where the California Department of Resources Recycling and Recovery (CalRecycle)
steps up. Headquartered in Sacramento, but with regional offices in Los
Angeles, Long Beach, Riverside and San Diego, CalRecycle is the state’s leading
authority on recycling, waste reduction, and product reuse.
In order
to understand just what businesses were contributing, in 2008 CalRecycle hired
Cascadia Consulting group to perform a comprehensive waste characterization
study. The study found carpet to be among the top ten materials going to California
landfills. CARE also has devised a good estimate of the annual flow of
post-consumer carpet going to California landfills based in sales of new carpet
into the state. More information may be found in the CARE Annual Report to CalRecycle
on page 19.
Although
carpet is a small percentage of that state’s total waste, it is big and bulky
and finding ways to eliminate 1.3 million tons from landfills a year is not to
be overlooked. Furthermore, targeting carpet falls in line with CalReycle’s aim
to be as efficient and effective with their time and money as possible. That
is, no matter if you are a single-family home or commercial store, you probably
have bought or disposed of carpet at some point in your life. CARE has made good progress in growing both
landfill diversion (recovery) and recycled output of used carpet as shown in
the following graph.
In
particular, CalRecycle focuses a large portion of their energy on education and
outreach to the commercial sector whose waste makes up about two-thirds of
California’s total waste stream. That said, in the end, any way to reduce the
amount of post-consumer carpet that ends up in landfills is a great way to free
up a vast amount of landfill space. Additionally, since post-consumer carpet is
actually quite a valuable resource, recovered and reused material further
reduces emissions by eliminating the energy required to extract virgin
material.
It is not
surprising then that CalRecycle sees AB2398 as both incredibly important and
exciting. As the overseer of CARE’s development of an implementation plan, CalRecycle
plays a pivotal role in how successful the legislation will be.
With
respect to the legislation’s initial hiccups, in a recent conversation with Mark
Oldfield, Communications Director at CalRecycle, he summarized AB2398 nicely
when he pointed out that all new programs are guaranteed to have challenges but
that without taking the initiative to create them you won’t ever reach goals.
In other words, the age old wisdom that the best rewards come from hard work
holds true.
Overall
Mark said the department “is very happy with CalRecycle’s collaborative
relationship with CARE and the healthy discussions they have been having to
move things along in a positive manner.” He is optimistic that they will
ultimately see a plan that works for everyone and perhaps a great way to
measure the legislation’s initial success will be through the new waste characterization
study CalRecycle hopes to perform in the coming year.
In the
meantime, CARE looks forward to continuing to work with CalRecycle to develop
the most efficient and effective Carpet Recycling Plan possible!
