Plastics
Task Force Factsheet
Misconception # 1: Plastics that go into a curbside recycling
bin get recycled. Not necessarily. Collecting plastic containers
at curbside fosters the belief that, like aluminum and glass,
the recovered material is converted into new containers. In
fact, none of the recovered plastic containers from Berkeley
are being made into containers again but into new secondary
products such as textiles, parking lot bumpers, or plastic lumber
all unrecyclable products. This does not reduce the use
of virgin materials in plastic packaging. "Recycled"
in this case merely means "collected," not reprocessed
or converted into useful products.
Misconception # 2: Curbside collection will reduce the
amount of plastic landfilled. Not necessarily. If establishing
collection makes plastic packages seem more environmentally
friendly, people may feel comfortable buying more. Curbside
plastic collection programs, intended to reduce municipal plastic
waste, might backfire if total use rises faster than collection.
Since only a fraction of certain types of plastic could realistically
be captured by a curbside program, the net impact of initiating
curbside collection could be an increase in the amount of plastic
landfilled. The Berkeley pilot program showed no reduction of
plastic being sent to the landfill in the areas where the curbside
collection was in operation. Furthermore, since most plastic
reprocessing leads to secondary products that are not themselves
recycled, this material is only temporarily diverted from landfills.
Misconception # 3: A chasing arrows symbol means a plastic
container is recyclable. The arrows are meaningless. Every plastic
container is marked with the chasing arrows symbol. The only
information in the symbol is the number inside the arrows, which
indicates the general class of resin used to make the container.
The attorneys general of 11 states objected to false and misleading
claims about plastic recyclability. The recent settlement that
they reached with the American Plastics Council paves the way
for a first-ever definition of what claims can or cannot be
made about plastic recycling and recyclability.
Misconception # 4: Packaging resins are made from petroleum
refineries waste. Plastic resins are made from non-renewable
natural resources that could be used for a variety of other
applications or conserved. Most packaging plastics are made
from the same natural gas used in homes to heat water and cook.
Misconception # 5: Plastics recyclers pay to promote
plastics recyclability. No; virgin resin producers pay
for the bulk of these ads. Most such ads are placed by virgin
plastic manufacturers whose goal is to promote plastic sales.
These advertisements are aimed at removing or diminishing virgin
plastics greatest challenge to market expansion: negative
public conception of plastic as unrecyclable, environmentally
harmful, and a major component of wastes that must be landfilled
or burned.
Misconception # 6: Using plastic containers conserves
energy. When the equation includes the energy used to synthesize
the plastic resin, making plastic containers uses as much energy
as making glass containers from virgin materials, and much more
than making glass containers from recycled materials. Using
refillables is the most energy conservative.
Misconception # 7: Our choice is limited to recycling
or wasting. Source reduction is preferable for many types of
plastic and isnt difficult. Opportunities include using
refillable containers, buying in bulk, buying things that dont
need much packaging, and buying things in recyclable and recycled
packages
Plastic packaging has economic, health, and environmental costs
and benefits. While offering advantages such as flexibility
and light weight, it creates problems including: consumption
of fossil resources; pollution; high energy use in manufacturing;
accumulation of wasted plastic in the environment; and migration
of polymers and additives into foods.
Plastic container producers do not use any recycled plastic
in their packaging. Recycled content laws could reduce the use
of virgin resin for packaging. Unfortunately, the virgin&endash;plastics
industry has resisted such cooperation by strongly opposing
recycled -content legislation, and has defeated or weakened
consumer efforts to institute stronger laws. Plastic manufacturers
recently decided that they will not add post consumer materials
to their resins used in the USA.
There is a likelihood that establishing plastics collection
might increase consumption by making plastic appear more ecologically
friendly both to consumers and retailers. Collecting plastics
at curbside could legitimize the production and marketing of
packaging made from virgin plastic.
Studies of garbage truck loads during the recent
plastic pick-up pilot program showed no reduction of "recyclable"
plastic containers being thrown away in the pilot areas (in
fact, there was a slight increase). Due in part to increased
plastic use, glass container plants around the country have
been closing, including Anchor Glass Container Corporation in
Antioch, putting 300 people out of work
Plastic recycling costs much and does little to achieve recycling
goals. Our cost/benefit analysis for implementing curbside plastics
collection in Berkeley shows that curbside collection of discarded
plastics: involves expensive processing; has limited benefits
in reducing environmental impacts; and has limited benefits
in diverting resources from waste.
Processing used plastics often costs more than virgin plastic.
As plastic producers increase production and reduce prices on
virgin plastics, the markets for used plastic are diminishing.
PET recyclers cannot compete with the virgin resin flooding
the market.
Increasing the capture rates of glass, paper or yard debris
in Berkeley could divert more resources from landfills than
collecting plastics at curbside. The "recyclable"
plastic to be collected in Berkeley at most would only amount
to 0.3% of the waste stream.
Five Strategies to Reduce
the Environmental Impact of Plastics
1. Reduce the use
Source reduction Retailers and consumers can select products
that use little or no packaging. Select packaging materials
that are recycled into new packaging - such as glass and paper.
If people refuse plastic as a packaging material, the industry
will decrease production for that purpose, and the associated
problems such as energy use, pollution, and adverse health effects
will diminish.
2. Reuse containers
Since refillable plastic containers can be reused about 25 times,
container reuse can lead to a substantial reduction in the demand
for disposable plastic, and reduced use of materials and energy,
with the consequent reduced environmental impacts. Container
designers will take into account the fate of the container beyond
the point of sale and consider the service the container provides.
"Design for service" differs sharply from "design
for disposal".
3. Require producers to take back resins
Get plastic manufacturers directly involved with plastic disposal
and closing the material loop, which can stimulate them to consider
the products life cycle from cradle to grave. Make reprocessing
easier by limiting the number of container types and shapes,
using only one type of resin in each container, making collapsible
containers, eliminating pigments, using water-dispersible adhesives
for labels, and phasing out associated metals such as aluminum
seals. Container and resin makers can help develop the reprocessing
infrastructure by taking back plastic from consumers.
4. Legislatively require recycled content
Requiring that all containers be composed of a percentage of
post-consumer material reduces the amount of virgin material
consumed.
5. Standardize labeling and inform the public
The chasing arrows symbol on plastics is an example of an ambiguous
and misleading label. Significantly different standardized labels
for "recycled," "recyclable," and "made
of plastic type X" must be developed.
