DE bottle refund law: Mend it, don’t end it, say advocates

A volunteer poses with the bottles and cans collected at a Massachusetts watershed cleanup.

A month after the governor of Delaware proposed dumping the state’s beverage container refund law in favor of a new tax for community recycling, in-state and national environmental groups have come out against the recommendation.  Delaware is one of 11 states that has a law providing for beverage container refunds, which are strongly opposed by the beverage industry and some beverage retailers.

Is A Pill Take-Back Law in Our Future?

As the product stewardship movement gains steam, attention is turning to the issue of unsafe disposal of residue or unwanted consumer pharmaceuticals.  The widespread detection of pharmaceutical residues in public waters and fish has raised biologists’ concerns.  In Minnesota, the popularity of public-sponsored take-back days and a coming legislative proposal in the 2010 session to create a network of collection facilities, funded by pharmaceutical makers, adds a new twist to the problem.

Asian Carp Near Great Lakes: Are They So Bad?

U.S. Fish and Wildlife Service biologists with a bighead carp, one of two species whose entry into the Great Lakes is sparking widespread concern.

Last week’s edition of Great Lakes Asian carp news brought both a U.S. Supreme Court decision and disclosure of the species’ environmental DNA in Lake Michigan.  But as members of Congress, state officials and Great Lakes advocates scramble to prevent a self-sustaining Asian carp population in the Great Lakes, a Minnesota commentator has challenged the prevailing wisdom, asking whether such a population would really be so detrimental to the Lakes and their resources.  Among other things, commentator Greg Breining argues whether the idea of a “healthy ecosystem” is valid and whether so-called invasive species are often a bad thing.

MN Solid Waste Reform Could Sharply Reduce Greenhouse Emissions


A new Minnesota stakeholder report identifies 38 solid waste reform recommendations that could dramatically reduce the state’s greenhouse gas emissions.

A report submitted December 31 to the Minnesota Pollution Control Agency (MPCA) outlines 38 ways the state could achieve a 20-year reduction of 52.5 million metric tons of carbon dioxide equivalent emissions through changes in solid waste policy and practices.

Coordinated by the Minnesota Environmental Initiative (MEI), a nonprofit organization, the report contains 22 consensus recommendations from a roup of stakeholders and another 16 with majority support in the group.

State E-Waste Laws Successful, But May Be Challenged

Even as more states put e-waste laws into effect, a legal challenge to New York City’s law is raising issues about their future.  E-waste laws are just one example of a growing U.S. movement toward extended producer responsibility (EPR). Nineteen states and New York City have passed electronics EPR laws that require electronics manufactures to pay for and facilitate collection and recycling of their products at the end of consumer use.

But the Consumers Electronic Association (CEA) and the Information Technology Industry Council (ITIC) have sued to block New York City’s law because of a feature requiring door-to-door collection of the waste products. Manufacturers must provide such an option for city residents disposing of electronic devices heavier than 15 pounds.

Barn Owl’s Wisconsin Appearance A Rare Event

The Common Barn Owl is not so common in Midwestern states where it’s considered vulnerable. A recent surprise appearance in Wisconsin highlighted the species’ fragile status in the region.

A raptor listed as an endangered or threatened species in seven Midwestern states made a rare appearance in Wisconsin late in 2009.  The ailing barn owl, which couldn’t fly or stand when rescued in Mequon, is being rehabilitated in the Pine View Wildlife Rehabilitation Center in Fredonia.

Although once abundant in the Midwest — and relatively plentiful globally — the common barn owl has plummeted in population in the seven states since the early 1960s.  A combination of habitat loss from farmland development and the past use of toxic pesticides has depressed barn owl numbers in the region.  Barn owls are more susceptible than other owl species to pesticides, although most of the problem chemicals affecting them are no longer in use.

Michigan Offshore Wind Proposal Stirs Waves

A map prepared for Michigan’s Great  Lakes Offshore Wind Council shows areas of high wind power production potential in the state’s offshore waters.

One of the first proposals for a major offshore wind project in America’s freshwater has surprised Michigan regulators and begun to stir opposition from onshore property owners. But the company behind the proposal says it has the potential to help right Michigan’s struggling economy with new jobs and leadership in wind energy development.

First disclosed last month, the Scandia Wind proposal to install 100 to 200 wind turbines two to four miles offshore in Lake Michigan for a 1,000-megawatt project comes after a September report by the state’s Great Lakes Wind Council.  That report outlined high potential areas in the state’s Great Lakes for wind power, while recommending turbines be placed as least six miles offshore.

Coalition Says MN Climate Solution Includes Nukes

The Prairie Island nuclear plant at Red Wing, Minnesota, on the Mississippi River.  Nuclear power advocates want to repeal the state’s 15-year-old ban on new nuclear plants.

The state that enacted one of the nation’s most farsighted clean energy laws in 2007 may be a battleground over nuclear power in 2010.  A coalition of interest groups wants to repeal Minnesota’s 15-year-old moratorium on new nuclear plants. Like pro-nuke interests elsewhere, the Minnesota coalition is arguing that nuclear power is a clean solution to climate change problems.

The 2007 Next Generation Energy Act mandates that Minnesota generate 25% of its energy from renewable sources by 2025.  It also sets a state goal to reduce electric demand 1.5% per year through efficiency and conservation programs. The law defines renewable sources as solar, wind, small hydro, hydrogen and biomass.

But nuclear power advocates want to add nuclear energy to the mix. The so-called Sensible Energy Solutions for Minnesota says it includes business, labor and environmental leaders, although no organized environmental groups support the repeal. A board member of SESM says calls nuclear “the most sensible and carbon-free base-load electricity source in existence.”

Curbside Vs. Deposit and GHG Reduction

The beverage container industry continues to fight state and national container legislation despite evidence that such laws could contribute significantly to greenhouse gas reduction while providing energy, recycling and litter control benefits. The industry says community recycling programs, which put the cost burden on communities rather than container manufacturers, are a superior system for processing bottles and cans.

The latest weapon in the industry’s arsenal is a report commissioned by itself; the American Beverage Association (ABA) that says bottles, cans and packages made by its members are easily recyclable because community recycling programs that can handle them serve an overwhelming majority of Americans. Getting more consumers to capitalize on the programs, the study suggests, is the best way to recycle the containers.

But it’s not that simple.

Who’s Better at GHG Reduction (and Sustainability?) Your Community Recycling Program or Their Deposit?
