Solid Waste Primer
Our culture of
consumption and waste is not sustainable.
The millions of
tons of useful materials
we dispose is costly,
consumes limited resources, pollutes our air and water, accelerates
global warming, and
degrades our health and quality of life.
-
Over 12 million tons of solid waste per year
is generated in Massachusetts, including municipal (MSW),
commercial, and construction and demolition (C&D). About half of
it is recovered through recycling, composting and reuse,
including asphalt, brick and concrete, yard waste, metal, paper and
plastic, TVs, car batteries, white goods and tires. Most of these
materials are banned by regulation from disposal, but . . .
-
More than half of our recyclable commodities (paper, metals, plastics, etc), and 2/3 of
compostable organic waste (food and yard waste) still winds
up in the trash. According to a Tellus Institute 2003 report
(“Waste Reduction Program Assessment and Analysis for Mass.”
http://www.tellus.org/index.asp?action=4
), about 2.5 million tons of residential and commercial
recyclable commodities and an additional 1.5 million tons of
compostable organics are still buried or burned on Massachusetts
each year. In the fifteen SSRC member towns, putting recyclables in
the trash costs the municipalities (and residents) an estimated
$3 million/year in disposal costs.
-
Statewide, this cost is well over $100 million. And the
lost commodity value of the wasted materials approaches that of
disposal.
-
Of the >6 million tons of materials disposed in
Mass., over 1.5 million tons/year are exported to other states,
because Mass. doesn’t have the capacity to manage it in state. This
is viewed as an unsustainable practice, so the Mass. DEP’s
Beyond 2000 Solid Waste Master Plan
http://www.mass.gov/dep/recycle/regs.htm set a goal of 70% waste
reduction through less disposal, more recycling and more use of
recycled products , and no net export of trash. Given that 4
million tons of recoverable materials are currently wasted, this is
an achievable goal.

Production, Pollution and Waste
-
Producing virgin products
from raw materials, and disposing in landfills and incinerators
produce much greater amounts of pollutants than recycling and
composting do, especially
greenhouse gasses, but also toxins
such as mercury and dioxin. Recycling also requires far less
energy than producing virgin products. For instance, the
environmental impact of trashing just the 1.8 million tons/year of
paper products that are wasted
in Mass. and making new paper from wood instead of recovered paper,
is as follows:
~ Trees cut from
forest, at 17 trees/ton: 31 million
~ Additional fuel to make
paper from trees (241 gal/ton, 60% more than recycled): 440
million gallons
~ Additional CO2 generated
from manufacture of virgin paper (21 lbs/gal fuel):
4.6 million tons
~ Tons CO2 that
would have been absorbed by the trees that were cut (1
ton/year/tree): 31 million tons
~ Tons CO2 generated
by incinerating unrecovered paper* (1.5 tons CO2 /ton
paper): 2.8 million tons
~ Tons of additional pollutants
released into the water: lots.
* landfilling produces methane, which is 20 X more
potent a greenhouse gas than CO2.

How has the State funded efforts to solve our waste problems?
o
The Clean Environment Fund
(CEF) was created in 1990 by the Legislature (MGL Ch 94 Sec. 323F).
All unclaimed bottle deposits were to go into the CEF. The law
stated that all monies in the Fund were to fund recycling,
composting, solid waste and source reduction infrastructure,
outreach, projects and programs through Executive Office of
Environmental Affairs and Dept. of Environmental Protection.
Funding actually appropriated by the legislature for
recycling from CEF peaked in FY02 at $15.8M (2 line
items, 2010-0100, 2210-0110). The legislature consistently ignored
its own law, which Governor Romney repealed in 2003 (along
with most other “dedicated funds”) to remedy the budget crisis. The
legislature did not overturn the repeal in spite of our pleas.
o
The CEF took in over $37M in FY03, and had a
surplus of $25M at the time of its repeal. The money that was
intended to fund waste reduction efforts was absorbed into the
General Fund.
o
Funding for waste reduction dropped to $3.5M
in FY04, of which $1.4 was earmarked to subsidize
redemption center operations.
o
The earmark for redemption centers was moved to its
own line item (2010-0200) in FY05, leaving recycling line
(2010-0100) at $2.1M. This amount was marginally increased
to $2.4M in FY06.
o
The Recycling line item is used to maintain support
staff of about 25 at Mass. DEP, who set waste policy and provide
technical assistance and guidance to all municipalities, private
sector and nonprofits. In FY05, they distributed about $200K in
equipment grants for such items as compost bins, kitchen scrap
buckets, public area recycling containers, setout bins, Pay as You
Throw startup costs, bin stickers, and wheeled carts. The SSRC
received assistance to place paid ads in the local papers, leveraged
by a larger grant from SEMASS to run concurrent radio ads on the
same topics.
o
DEP has been doing a lot with a little, but the
efforts pale in comparison with what needs to be done to reduce and
manage our trash in state.
o
A report released in 2003 by the Tellus Institute
(“Waste Reduction Program Assessment and Analysis for Mass.”
http://www.tellus.org/index.asp?action=4
), concluded that to achieve the goals of the Solid Waste Master
Plan and achieve sustainable waste management by 2010, funding
would need to be returned to a level of $15M/year through 2010. |
Why should our State's leaders
increase funding for recycling, and revive the CEF?
o
Mismanaging trash by disposing of vast amounts of
useful materials is costly, consumes limited resources, pollutes the
air and water, and adversely affects our health and quality of life.
o
Massachusetts used to be recognized as having the
most progressive recycling programs in the country. Dedicated funds
available through the CEF had made this possible. Examples include:
§
The CRT waste ban and electronics recycling
infrastructure, first developed in Massachusetts, which was possible
because CEF funds were available to support electronics collection
programs in the early stages.
§
MRIP program has been highly effective in motivating
municipalities to improve programs on multiple levels (see below)
§
WasteCap of Mass. and the Chelsea Center provided
practical guidance to businesses, and research on innovative uses
for waste products such as fish guts.
Programs supported by DEP Recycling funding
have been reduced to bare minima or eliminated:
o
Municipal Recycling Incentive Program (MRIP)
required munis to set up proven programs to qualify for no-strings
payments based on recycling tonnage; often paid recycling staff -
GONE
o
Municipal recycling equipment grants –
greatly reduced
o
Technical assistance grants –
hanging on
o
WasteCap Business Alliance –
unstaffed phone number and website now
o
Chelsea Center for Recycling and Economic Development
- GONE
o
Lowell Center for Sustainable Production -
GONE
o
Grants and loans to businesses investing in recycling
equipment and recycled material use in products –
GONE |
What does the SSRC Recommend?
o
Reinstate the CEF - Section 323F,
to revive the development of recycling infrastructure and education.
wise use of this would reduce our generation of burned or buried trash
and increase recovery of useful materials currently disposed by 2.5
million tons per year
o
Increase funding for Statewide recycling programs
to at least pre-2002 levels of $8-9M/year. Ideally,
appropriate the full CEF to its intended target of
sustainable waste management.
o
Raise deposit bottle handling fee
from $.0225 to $.0275 or $.03 per bottle, or provide regulatory relief
and use $1.375M subsidy they now need for other recycling related
programs and services that have greater impact.
o
Update the Bottle Bill to include all on-the-go beverage
containers.
This
would double the recovery rate for nondeposit water, juice and sports
drink containers, and collect more unclaimed deposits to fund programs
to further increase their capture. About 35% of nondeposit containers
are recycled, while about 68% of deposit containers are redeemed. (It
is not known how many unredeemed containers are recycled through
municipal programs).
o
Increase the bottle deposit from a nickel to a dime.
This would increase the redemption rate of deposit containers well above
the current 68%. |

emissions)
What are greenhouse gases? Jean-Marc Jancovici
...in order to be able to compare them
..., it is possible to calculate, for each, a "global warming
potential", or GWP in short, that allows to know how much additional
greenhouse effect we generate when we emit one kg of a given gas.
Here are the relative GWPs of the 6
gases of gas families covered by the
Kyoto protocol (Perfluorocarbons
and Hydrofluorocarbons are sub-famillies of halocarbons),

From
IPCC, 2001
The above table means that if we emit
today 1 kg of methane in the atmosphere, we will increase the cumulated
greenhouse effect, for the coming century, just as much as 23 kg of CO2
(also emitted today). In short, we could say that a kg of methane
"makes" 23 times the greenhouse effect that a kg of CO2
makes, or that methane is a greenhouse gas 23 times more potent than CO2.
In the same idea, regarding the
greenhouse effect, a kg of sulfur hexafluoride equals 23,9 (metric)
tonnes of CO2,
that is the annual emissions of 3 French ! (or of one American).
Fortunately, the emitted quantities remain low for the moment (see
below).
At last, rather than mentionning the
mass of carbon dioxide, engineers and economists often use the
carbon equivalent.
Just as lenghts are measured in meters, greenhouse gas emissions are
measured in carbon equivalent.
By definition,
a kg of CO2
is worth 0,2727 kg carbon equivalent,
that is the weight of the sole carbon in a kg of CO2. For the other gases
gaz, the carbon equivalent is definded as :
carbon equivalent =
relative GWP x 0,2727
It may seem very
complicated, but actually it is very simple, because that
way when we burn one kg of pure carbon, we obtain one kg of
carbon equivalent in CO2.
This then enables to know how much carbon equivalent a
hydrocarbon will produce when burning, by simply measuring the
weight of carbon per kg of hydrocarbon burnt (burning hydrogen
produces water, not taken into account as explained at the top
of the page).
And then the carbon
equivalent of a kg of hydrocarbon that is burnt is simply the
weight of carbon in this kg. Simple, I said !
For our main greenhouse gases, the
carbon equivalents are therefore the following :
