Recycling your Christmas tree

Christmas tree drop-off sites are becoming more common.

So you’ve put away all the ornaments and the lights and the tinsel... and you have that bare tree in your living room... what now?  It’s not illegal in Michigan to throw your Christmas tree away... but a lot of cities and counties do recycle them... and chip them up into mulch.  The recycling website Earth 911 lets you type in your zip code to find tree drop-off sites near you.

I talked with Marsha Gray - she's the executive director of the Michigan Christmas Tree Association. She says the first thing you should do if you want to recycle your tree is call the people who pick up your trash.

“You want to ask them if they do a separate collection for the trees. If they’re collecting them separately from your regular trash, that means they’re most likely recycling, probably chipping those trees into mulch. If they’re collecting at the same time and they’re going right into the bin that means they will go to the landfill."

Marsha's tips for recycling - or reusing your tree:

  • If your waste hauler won't recycle your tree... call your city or county park department.  There's a good chance they offer a drop-off site for the first few weeks of January.
  • Stand your tree up next to the birdfeeder for a little perching spot for birds while they wait their turn at the feeder.
  • Use the branches as plant stakes
  • If you're really ambitious, break out the chainsaw and remove the branches (you don't want to burn these in a fire - they can spark!), cut the trunk into logs, and add them to your log pile to season for a year.  Free firewood for next Christmas!

Supreme Court Gives You the Right to Sue the State

The Michigan Supreme Court says anyone can sue the state if they believe it's acting in a way that harms the environment. 

Michigan Radio's Jennifer Guerra talked with Nick Schroeck with the Great Lakes Environmental Law Center to find out what this decision means. He says if a company wants to do something like discharge treated wastewater into a creek or a river, for example, it needs a permit from the state to do so:

“The way our environmental law works, you have to have a permit to pollute, as it were. That means that the state regulates the amount of pollution that’s allowed into the waters of the state.”

New construction, expansions in Kalamazoo must furnish bike racks

New or expanding businesses in the City of Kalamazoo will be required to include space to park bicycles.

Mayor Bobby Hopewell says it is part of a broader plan to promote sustainability.

 “We talk about wanting to attract young people and keep young people; we talk about wanting to be a vibrant urban core community. These are the things that urban communities do. They recognize that we can’t only be about the automobile, we have to be about how everyone gets around in the community.”

Only new buildings or those that are expanding are mandated to accommodate bike racks. The number required depends on how many people will use the building, with a maximum of 25 spaces required. Existing public and private entities will be encouraged to add places for their customers and employees to park their bikes.

Crews working this summer to collect to oil in the Kalamazoo River near Battle Creek.

This week the energy company involved in an oil spill that reached the Kalamazoo River is revising the amount of total oil that leaked from a ruptured pipeline near Marshall. Enbridge Energy submitted the update to US Department of Transportation Pipeline and Hazardous Materials Safety Administration this week.

A House of Straw

Step aside, Three Little Pigs. 

Strawbale buildings have come a long way from the flimsy huts a wolf could blow down.  The Trumpey family in Grass Lake, Michigan, built their 2,000 square foot home from straw, clay, field stones all sourced locally - and timber salvaged from trees killed by the emerald ash borer. 

They're living off the grid - everything they do: washing laundry, firing up the sawmill, watching TV -  is powered by their solar panels (with a small backup generator for those cloudy weeks in the winter).

Joe Trumpey says fire is a considerable risk before you seal up the straw walls with adobe. 

“When you’re building the building all the open straw is a huge fire hazard at that point so we were really careful not to have any smokers around and no open fires. Once it’s coated with mud the fire proofing is really in place.”

You can hear Joe and Shelly talk about the experience of building with straw.

The stats:

  • 1500 bales of straw
  • the 18-inch thick walls are insulated with the straw, plastered on either side with adobe mud - giving the Trumpeys 2-3 times the insulation value of a conventional home
  • 50 tons of field stones, dug from their own farmland
  • 7 years of planning, 2.5 years in the making
  • Cost: about $75 per square foot - but the family did 99% of the labor themselves

I was hoping to get to this post sooner, but the day just got away from me.

Today seemed unusually short. That's because it IS the shortest day of the year.

And soon, very soon, the days in the northern hemisphere will start to get longer.

Oldest Net-Zero House in America

The Environment Report has been following an effort to make a Michigan house the oldest net-zero house in America. That means in a year the home will produce as much energy or more than it uses. Lester Graham reports... the owners are at the point where they can reach that goal.

Matt and Kelly Grocoff bought an old house in a historic neighborhood in Ann Arbor a few years ago. Matt wanted to show that making an older home an energy efficient showcase made more sense than building new.  Kelly was just a little skeptical.

“When we first bought the house and Matt was talking about what he wanted to do and what some goals might be, part of me was sort of like yeah, yeah, you know. Matt’s a dreamer. He likes to think big. And it’s really happening.”

 

Find out how to assess your own home's energy efficiency.
