Happy Earth Day, Citizens of Minneapolis. Your City government wants you to help make our city a Zero Waste city. On the City website, a page is devoted to ways you can be a "Zero Hero" and reduce environmental waste.
Here
are two of the tips offered on the page, with editorial comments
highlighted in green:
Buy It Durable and Maintain It To Last!
Long
lasting, durable goods cost more at first but save money in the long
run. Zero Heroes find that durable products break down less often
too, meaning fewer repair bills. Like old
houses built with pride from quality materials.
Creatively Reuse
Zero
Hero creativity can play a big role in preventing waste. There are
many things around the house that can have new uses. Like
the house itself.
And
here's a third tip I'd like to add:
Don't
poison the neighborhood with airborne hazardous materials.
The
City is to be commended for its excellent recycling program. But
before we congratulate ourselves on saving the Earth by
recycling pop cans and composting potato peels, we need to look at a very
negative environmental impact that's totally ignored: the demolition
of old houses. While the City concerns itself with recycling plastic
grocery bags, it approves and encourages the demolition of well-built
existing houses. These demolitions--seven in the Wedge alone during
the last couple of years--send toxic particulates into the air and
many hundreds of tons of building materials into the landfill.
But
you don't have to take my word for it. A report produced by the
Preservation Green Lab of the National Trust for Historic
Preservation provides the most comprehensive analysis to date of the
potential environmental benefit of building reuse. This
groundbreaking study concludes that when comparing
buildings of equivalent size and function, building reuse
almost always offers environmental savings over demolition and new
construction.
Some important findings in this study by the National Trust:
The Greenest Building: Quantifying the Environmental Value of Building Reuse
Reuse Matters. Building reuse typically offers greater environmental savings than demolition and new construction. It can take between 10 to 80 years for a new energy efficient building to overcome, through efficient operations, the climate change impacts created by its construction. The study finds that the majority of building types in different climates will take between 20-30 years to compensate for the initial carbon impacts from construction.Scale Matters. Collectively, building reuse and retrofits substantially reduce climate change impacts. Retrofitting, rather than demolishing and replacing, just 1% of the city of Portland’s office buildings and single family homes over the next ten years would help to meet 15% of their county’s total CO2 reduction targets over the next decade.
Design Matters. The environmental benefits of reuse are maximized by minimizing the input of new construction materials. Renovation projects that require many new materials can reduce or even negate the benefits of reuse.
The Bottom Line: Reusing existing buildings is good for the economy, the community and the environment. At a time when our country’s foreclosure and unemployment rates remain high, communities would be wise to reinvest in their existing building stock. Historic rehabilitation has a thirty-two year track record of creating 2 million jobs and generating $90 billion in private investment. Studies show residential rehabilitation creates 50% more jobs than new construction.
Now
to turn to the "Don't Poison the Neighborhood" part. . .

North Side resident Brian Finstad, who recently witnessed a demo on Dupont Avenue with no lead containment (see photo), spent hours contacting various agencies about the toxic cloud spreading through the area. According to Brian, this is "not a problem of permitting, but of practices and enforcement." The negative environmental impact of these lead-spreading demolitions is "one of the great unstudied public health issues of urban neighborhoods." When 2320 and 2316 Colfax Avenue South were demolished, a similar environmental nightmare ensued. One guy wrecked the houses with a backhoe, while another guy walked around with a garden hose. Pathetic.

Until the City takes into consideration the unhealthy and wasteful impact of its market-driven obsession with commercial residential construction, Minneapolis won't be anywhere near achieving "zero waste" status.
The greenest building is the one already built. Period.
