The document discusses the challenges and advancements in environmental sustainability within the consumer products sector, particularly focusing on energy use, recycling, and the use of sustainable materials in electronics. It highlights the impact of information and communication technology on carbon emissions and reviews significant strides made in eliminating hazardous substances from electronic products. The conclusions emphasize that while there has been progress in recycling and energy efficiency, further improvements are needed in renewable chemistry and reducing standby energy loss.

How big are the impacts of
consumer products
In the big picture?

3. Bringing a little more focus
to Information and Communication Technology (ICT)
•In 2007, ICT accounted for
830 MtCO2e, about 2% of
estimated total emissions
from human activity
•A typical cell phone
produces 25kg of CO2/yr, or
93 Mt in 2008 = 11% of of
total ICT
•Handsets are 0.2% of
global carbon footprint

ITXPO conference, April 2007.

4. 1. Substances of Concern
Successes
•Elimination of RoHS substances (EC Directive July 2006)
•Spill-over effect to US and other regions applies to most
consumer products
•Voluntary elimination of PVC, phthalates, TBBPA, etc.
•Substance reporting now standard practice
•Materials Databases now contain wealth of data
Pb
Cd
Hg
Cr(VI)
PBB, PBDE

5. So we’re done with substance
replacement, right? (Wrong!)

10. Changing Expectations
•38% of 1000 consumers in the US polled in October 2009 claim to have
recycled outdated mobile handsets.
•Nearly 70% donated their old handsets to charity organizations
and received charitable contribution tax deductions.
•Fewer than 5% recycled their handsets without receiving compensation
of any kind.
•Of those who had not yet recycled a handset, 98% were prepared to
return handsets to a store, charity, refurbishing company or the
manufacturer –
•But only in return for cash, store credit, or tax deduction.
“Many consumers in the US are prepared to help the environment by
recycling their old handsets, but only if there is a financial incentive
to do so.”

11. End of Life Recovery & Recycling
B. Renewable Plastics – Green Chemistry Needed
for Fullcycling not just Recycling
Unlike metals, plastics cannot recycle repeatedly
(thermoplastics), or really at all (thermosets).
So… Observations on two plastics key to electronics:
•Thermoplastic – polycarbonate
•Used in housings, doors, lenses
•Thermoset - epoxy
•Used in PWB’s & molded component packages

15. Emerging Sources of Propylene
• Catalytic conversion of synthesis gas from natural gas, coal,
biomass or other hydrocarbon source
• Oxygen-blown natural gas reforming, synthesis and
methanol to propylene conversion
• Sugar cane to methanol to propylene
• Commercialization remains to be realized

16. Recycled Thermoplastics
A ‘worry list’ for Engineering applications
• Mixing polymer types, grades, manufacturers
• Unknown additives, catalysts, other composition variations
• Foreign material: metals, inorganics, adhesives, coatings
• Chemical changes in functional groups, oxidation
• Molecular weight degradation
• Branching, cross-linking, initiator site creation
• Change in mechanical properties (modulus)
• Change in physical properties (density, color)
• Change in processing behavior (melt flow)
• etc.
Plastics recycling must be carefully implemented.
A renewable source of virgin resin would be preferred.

Ed., p. 976, (Munich: Hanser, 2001),

18. Standby Energy Drain Was Significant

Schematics: STMicroelectronics
Analog Supply Switch Mode Supply
•Analog supply: power drain
remains even with no load
•Switch mode supply: able to
dynamically control vs. load

19. Power Consumption Keeps Going Down
while functionality continues to increase
Computer display 15 yr. trend
Same trend applies to cell phone features,
media players, memory chips, etc. etc.
Electronics is driven by power efficiency – examples from author’s 2009 scrapbook:
•1-milliohm RDSon 30V FET for power supplies
•Low power 8051 microcontroller, 10 nA in sleep mode
•30% reduction in power consumption using GaN for power amplifiers
•10X reduction in CMOS transistor leakage through process annealing
•TechAmerica Innovator Award to CEO of power controller chip maker
“Low-power IC’s and low-power designs are…not just for “environmental/green”
reasons… The simple fact is that low-power designs enable longer product run
times from a given battery pack.” Bill Schweber, Power Management DesignLine, 11/30/2009.

20. Beyond the Handset
Infrastructure, network, cloud, grid…
“Cloud Computing…a new paradigm…shifts the location of this infrastructure
to the network.” L.M. Vaquero et. al., A Break in the Clouds: Towards a Cloud Definition, ACM SIGCOMM Computer Communication Review, 39(1):50-55 (Jan. 2009)
Life Cycle Assessment of ICT Products more complex than ever

21. Network Improvements
Predicted to yield 42% drop in carbon emissions by 2013 through
•integration of clean energy sources: solar, wind, and fuel cells
•more energy-efficient network equipment (base stations and RF power amplifiers)
•more efficient network architectures and topologies
