When people talk about making their home energy independent, they often talk about solar panels and wind turbines. But before all of that, a home has to be tight. That’s not as exciting, but necessary. Lester Graham is following Greenovation.tv’s Matt Grocoff as he tries to make his home the oldest net-zero-energy house in America.

When people talk about making their home energy independent, they often talk about solar panels and wind turbines. But before all of that, a home has to be tight. That’s not as exciting, but necessary. Lester Graham is following Greenovation.tv’s Matt Grocoff as he tries to make his home the oldest net-zero-energy house in America:

The note on Matt’s door told me to come on in and head for the basement. Matt’s 110 year old home has what’s called around here a “Michigan basement.” Basically, cement floor, stone walls, low ceilings. Not glamorous.

Matt is spraying expanding foam insulation up in that area where the floor framing sits on the foundation. The sill plate… which is basically nothing more than one-and-a-half inches of wood between inside your home… and the great outdoors.

“There’s no insulation between your house, or your living part, and the foundation itself.”

Maybe you’ve been in the basement of an old house and sometimes you can actually see daylight through the sill plate in places. Those leaks need to be sealed. That could be done with caulk. Then the area needs to be insulated. That could be done with fiberglass insulation.

“What we decided to do is to do both at the same time, seal and insulate, is to use a do-it-yourself spray foam insulation kit from Tiger Foam. There’s plenty of professionals out there, and for most people, that’s what I’d recommend you do, go to the professional. If money is an issue or if you’re a really handy person, these spray foam kits are fantastic.”

The foam insulation kit costs about 300-dollars. It’s basically two tanks -each about the size of a propane tank you’d use for an outdoor grill. A hose from each tank is attached to a spray gun that mixes the chemicals. The chemicals mix as they come out and the make a sticky foam that expands into nooks and crannies and then hardens after several minutes.

“Way easier than I thought they were going to be, by the way. I was actually terrified. I went back and read the instructions three – four times. And when I started spraying, it wasn’t that bad.”

“You still ended up with a goof, though.”

“I did have a goof. There was a little bit of foam there, dripping, when I forgot to turn on one of the canisters, but what ya– c’mon Lester.”

Matt’s goof means he’s going to have to wipe up some of the mess and spray again. But it’s not a disaster.

If you’ve got a big job… maybe new construction or a remodel that takes it down to the studs… you might want to consider a professional.

John Cunningham owns Arbor Insulation in Ann Arbor, Michigan. He says, sure, if you’re up to it… do it yourself.

“You could assume that it’d be cheaper to do it yourself and the kits are a really good option, especially for people that have smaller projects or they’re looking to do the work in a very specific time frame or in a distant location for instance.”

But the professionals are recommended for those big jobs. And right now there are federal tax credits for spray foam insulation– 30-percent up to 15-hundred dollars. That credit is limited though.

“The tax credit is available for the material only, so the contractor should be separating out the material and the labor. Also, there are additional incentives from some utilities and more incentives coming down the pike.”

Some states and even municipalities are considering incentives.

One final note… to use the spray foam, Matt Grocoff is decked out in a white haz-mat suit, latex gloves, goggles and a respirator…

“You’ve got to take all the safety precautions. You’ve got to wear your goggles, your suit. And it also can be messy too. Any overspray that gets in your hair will stay in your hair.”

And as he zips up, I get the hint that Matt has to get back to work.

“I do. I’ve got 30 seconds before this nozzle sets up. So, Lester, thanks again.”

“Sounds like my cue to get out of here. That’s Matt Grocoff with Greenovation-dot-TV. I’m Lester Graham with The Environment Report.”

“Thanks Lester.”

Should We Recycle Everything?

  • Right now, San Francisco is at 72% recycling. They also just passed legislation to make composting mandatory. (Photo source: Tewy at Wikimedia Commons)

Recycling has become the law in
San Francisco. Residents who fail
to recycle and compost will face
warnings and, eventually, a fine.
It’s part of the city’s goal to
eliminate waste altogether. But,
as Amy Standen reports, recycling
and composting can only take us
so far:

(conversation in Chinese)

Janis Peng is a foot soldier in San Francisco’s war against garbage. Today, she’s going door to door in a San Francisco Chinatown apartment complex, trying to convince the mostly elderly residents to make better use of their city-provided compost bin.

In fact, Peng is part of a city-wide effort to eliminate waste altogether. In 1989, California passed a law, which was considered radically ambitious at the time. They wanted to divert away from landfills 50% of the state’s garbage by the year 2000.

For San Francisco, that wasn’t enough.

“We got to 50%, and we said, ‘well we’re here now, what are we going to do next?’”

That’s Jared Blumenthal. He’s head of San Francisco’s Department of the Environment. Today, he’s in the backseat of a Toyota Prius. He’s on his way to a recycling press conference.

“So in 2003, we set the goal of 75% by 2010 and to zero waste by 2020.”

Right now, San Francisco’s at 72% recycling. City officials say that mandatory recycling will bring that number up even higher. But can any city ever get to zero waste?

(sound of trucks and machinery)

“It’s almost 9:45 in the morning and some of the trucks that went out this morning are coming in with their first loads.”

Robert Reed is a spokesman for Sunset Scavenger Company, in San Francisco. Here at Pier 96, dozens of workers stand by conveyor belts, sorting out the contents of an entire city’s worth of blue bins.

“All these materials go to different places, the glass goes to a glass plant, the paper goes to a paper mill.”

Sunset Scavenger sells these commodities to buyers here and in Asia. That generates revenue that helps fund the program. But recycling is expensive, in part because some products – like many plastics – cost far more to recycle than they’re worth.

“We’re dealing with clear plastic and opaque plastic and medium plastics. And many of these containers have three types of plastics.”

Aluminum and glass can be yanked off the conveyor belts with magnets and other machinery. But plastic has to be hand sorted.

Mark Murray is executive director of Californians Against Waste, a Sacramento non-profit group.

“We have seven different types of plastic resins and manufacturers invent new ones every day. And I know it might make us feel good to put those number sevens into the recycling bin, the scrap value is insufficient. It’s not sustainable recycling.”

Murray says he hears all the time from residents who want to eliminate waste all together.

“They recycle everything, but they can’t get their city to take a certain type of number 6 or 7 plastic in their program. And they’re mad at the city. But it’s not just about recycling everything we get. That’s not gonna solve the problem.”

That’s because some things may never make sense to recycle. Like ballpoint pens and plastic razors.

Murray say that maybe if the costs for those items included what cities pay to take them apart for recycling or to dump them in the landfill, maybe people would use less of them, bringing us a little closer to the holy grail of zero waste.

Company Trash, Classroom Treasures

(sound of Anita looking thru boxes)

Anita Gardner is rummaging through boxes of old tile samples. They’re still attached to those three-fold sample books you’d see at a design store. But she’s imagining what else the kids at her community center might make with them.

“You have to see it first, sometimes. Sometimes it doesn’t come. It comes later and then you go, ‘we can do this and we can do that.’”

Gardner is at a special event called ZeroLandfill. Furniture stores, architects and design centers can drop off unwanted materials, and people like Gardner can take whatever they want – for free.

“This has been a godsend to us, because we really don’t have a lot of money to spend on arts and crafts.”

Last year, she found a lot of unused fabric – so she taught the kids at her center to sew quilts.

“And a lot of children in our community have never even threaded a needle. Now they’re learning to use sewing machines. They’re learning to piece all types of fabric together. They’re learning patterns and designs. They have no idea, they’re actually learning math.”

And in inner city neighborhoods, where kids can go to bed cold in the winter, Gardner is especially pleased that she’s started a quilt-making trend. It also warms the hearts of the folks who organize ZeroLandfill.

David Fox helps to run these events in Cleveland.

“A lot of samples end up just being discontinued and then, where does this all go? And it ends up being thrown out a lot of time. Or – they just have so much stuff they just keep hoarding and hoarding and hoarding.”

About five years ago, some folks at architecture and design firms around Cleveland, as well as a carpet company, all started talking about what to do with their unwanted material. They were spending a lot of money to send it to the landfill. So they held a one-day drop-off for companies to recycle it.

Fox says they soon realized their trash might be treasure to artists and art teachers.

“It was a program that started as a one-day thing. Firms were able to come and drop stuff off. But it has turned into a yearly process and now it’s even gone to other cities.”

Fox says they’ve already saved more than 100 tons of material from going to the landfill.

Arts and crafts teacher Anita Gardner says it’s also provided innumerable lessons for kids and teenagers at her community center.

“They see now that anything can be art. Anything can be a craft. And it doesn’t have to cost a lot to be beautiful.”

ZeroLandfill has been training architecture and design firms how to organize these events regularly. They’re now held annually in cities around Ohio – and new ZeroLandfills are being held in Minneapolis, Louisville and Boston this year.
