CHICAGO --
The message rang out loud and clear: everyone in the U.S. solar
industry, from manufacturers to stakeholders, need to get on the same
page to figure out formal plans for end-of-life and take-back rules.
And
they need to figure out a process and plan starting now before it
becomes a really pressing issue — or else regulators and governments
will decide it for them. "Recycling has to be part of what we do," noted moderator John
Smirnow, VP of trade and competitiveness for the Solar Energy Industry
Association (SEIA), kicking off the Tuesday morning panel at Solar Power
International (SPI). "For the solar industry to be truly sustainable,
the whole supply chain has to be."
The solar energy industry "has a great story to tell," agreed Jim
Larson, principal consultant and Clean Tech practice lead at EORM, "but
we also have to deal with the backend of what we're doing."
The U.S. has roughly 10 GW cumulative installed capacity, nearly all
of it in the past three years — why worry about end-of-life issues now?
Larson showed projections of a tenfold surge in annual PV waste between
2014-2017 to 100,000 tons: "This issue is coming," he warned. And not
all modules are making it to their 20-25 year warranty levels, either,
plus there's other types of PV recycling such as manufacturing waste,
damage in the field, etc.
The industry has three choices: be proactive with an industry-led
program, stand back and wait for state legislations to put together
their own programs, or find a middle ground with the industry and states
working together to create a template for everyone. The longer the U.S.
industry takes to formalize its own PV recycling/end-of-life plan, the
higher the risk that they won't be making decisions for themselves. The
state of California already is mulling its own hazardous waste
requirements that would apply to PV waste and a variety of materials.
There are lessons to be learned — and pitfalls avoided — by how
related industries have dealt with end-of-life issues. Rich Vernam,
group manager, corporate environmental department, Panasonic Corp North
America, related how companies selling consumer electronics (TVs,
monitors, other IT gear) have had to wrestle with this. Without a
consistent industry-driven consensus, 25 individual states and Puerto
Rico have created a patchwork of different regulations; as a result
Panasonic has to juggle multiple reporting periods and dozens of
different regulations and deadlines. "It's been a "virtual compliance
nightmare," he said. Any federal effort to supersede states' patchwork
approach would be worse from Panasonic's view because it would default
to the most stringent state rules applicable.
By contrast, Vernam pointed out, the battery industry answered many
states' takeback mandates passed in the 1990s by coalescing a single
national program, a unified collective effort that created a "one-stop
compliance," he noted.
First Solar has long had its own recycling program, which was
explained by Sukhwant Raju, global director of recycling, operations,
and services. A prefunded program was recently updated to be funded with
project cash flows, which fits better with the company's market
sweetspot of utility-scale solar. The company has recycled around 48,000
metric tons to date, and does recycling in all its manufacturing
plants, scalable to accommodate future high volumes. Roughly 95 percent
of the semiconductor material in its modules is recovered, and 90
percent of the glass.
First Solar's first recycling program (circa 2006) processed about 10
tons per day, and the latest one (circa 2011) increased to 30 tons per
day, based on a more chemical-breakdown approach. Raju sees PV recycling
costs going below hazardous waste disposal within two years, and in the
next decade or so the company has plans to churn out 350 tons per day
using smaller mobile facilities to do onsite recycling.
There is value in some of the reclaimed materials that can help
offset the cost of recycling, the panelists noted; tellurium in First
Solar panels, for example has good value, as does glass, and the copper
and steel in the entire system have value. Raju added that their efforts
continue to find an end-market for recyclable laminate materials.
Having more valuable materials going in, such as gold, would help the
recovery cost model, but they'd be more costly up front as well,
panelists agreed.
SEIA's Smirnow noted that SEIA has a working group that's putting
together a white paper on PV recycling, which will help to develop a
policy recommendation for its board of directors. (He separately
indicated results likely will be publicized sometime early in 2014.
All panelists agreed that a consortium approach, inspired by Europe's
PV Cycle program but modified for the unique U.S. market, perhaps with
clear directions for residential vs. utility-scale solar. Raju offered
that manufactures and customers have to be the first ones on board with
the plan, with manufactures taking the lead and training customers to
understand that they'll play a key role, as well.
"It's got to be national, it's got to be voluntary, and it's got to be a consortium," summed up Vernam.
