There’s gold in your gray water

An inside look at the rainwater capture system’s holding tank

Along with a new age of sustainability comes new interest in gray water recycling and rainwater capture systems.  These systems capture water from your house’s bathroom sinks, showers and rainfall then reuse it to irrigate the lawn and flush the toilets.

The engineering behind the effort can be tricky, but in the simplest terms it goes like this: water from the “gray water sources” gravity-flows into a collection basin. A pump in the basin then pushes the water through a filter and disinfection array and into a storage tank.  The water in the storage tank is periodically circulated to keep it clear and bacteria-free. Finally, a pressure controlled pump automatically delivers recycled water to your irrigation system when your irrigation timer activates. It’s simplistically complex.

Whether on a household level or a commercial level, many have decided to invest in the water conservation effort.  Gray water recycling and rainwater capture systems can save 50 to 70 percent of a family’s monthly water usage. You’ll save that same 50 to 70 percent on your water bill.

How much does it cost to install? Do-it-yourself systems start at $3,500.  Systems for average sized homes start at $11,000.

Light recycler helps businesses dispose of fluorescent lights

The following post is by DJC staff:

People and businesses in Washington are now required to recycle fluorescent light bulbs and tubes. The new law covers residences as well as government, commercial, industrial, office and retail facilities.

Fluorescent tubes and compact fluorescent lights (CFLs) save energy but each light contains a small amount of mercury that can be harmful to humans and wildlife if it is not disposed of correctly. The mercury content in fluorescent tubes ranges from 3.5 milligrams to 8 milligrams or more for older lamps.

You can't throw these away now.

The most common types of lights that must be recycled include CFLs, fluorescent tubes and HID (high-intensity discharge) lights, such as mercury vapor, sodium vapor and metal halide lamps. It is now illegal to knowingly place mercury-containing lights in waste bins or landfills. All mercury-containing lights must be placed in a recycling container specifically designed to prevent the release of mercury. Mercury inside a light does not pose a concern while the light is in use and unbroken, but during disposal and waste handling, lamps are broken, releasing mercury vapor and potentially exposing waste handlers or others to mercury.

Mercury in the atmosphere is ultimately deposited back to the earth, rivers and lakes, where it can enter the food chain and accumulate in fish, which humans and other animals eat.

EcoLights was created in 1996 to recycle mercury-containing lights and both PCB and non-PCB ballasts. The company said it is a licensed “final destination” light recycler in Washington state.

Ecolights said almost every component of a fluorescent lamp can be recycled, including metal end caps, glass and the mercury phosphor powder. When lamps are recycled properly, they are crushed and the materials are separated under a continuous vacuum filtration process.

Glass, aluminum and phosphor powder are captured and recycled. Mercury phosphor powder is sent to a mercury retort for recovery of the mercury and rare earth metals in the powder.

EcoLights sells a pre-paid box for recycling. The company ships the box, protective inner bag, and instructions to users, who fill the box with lamps, and return it to EcoLights for recycling. EcoLights then e-mails a certificate of recycling to the user. The company said currently there are no fines or other legal consequences associated with non-compliance.

“EcoLights is committed to being a resource for helping businesses throughout the region understand and comply with the new law,” says Craig Lorch, EcoLights founder. “We want to make sure everyone is prepared for the transition.”

Information about the new law is available on the state Legislature website or at EcoLights.com.

Scrap metal demolition is green, but not always easy

The following post is from Elder Demolition:

About 40 percent of the solid waste produced in the U.S. comes from construction and demolition debris. In 1996, the U.S. Environmental Protection Agency reported that the debris generated from construction and demolition projects totaled 136 million tons. Since then, this figure has increased by 25 percent. Building demolitions are responsible for about 48 percent of this waste, while renovations contribute about 44 percent. Since steel is one of the most popular materials used in construction, green scrap metal demolition is getting a second look.

Scrap metal recycling can reduce disposal fees and demand for raw materials.

Builders are diverting metals harvested during demolitions from landfills for reuse in new projects. Instead of tearing down a building as fast as possible, builders deconstruct them in order to salvage parts they can reuse, recycle or sell. Scrap metal recycling isn’t a new concept in the metal industry. Here’s why:

It reduces demand. Steel and other metals have valuable minerals in them, such as nickel and chromium. By choosing to recycle scrap metal waste, you can help reduce the demand for raw materials and the energy required to refine them.

It saves money. Often you can reuse the metal salvaged during a green demolition, thus reducing disposal fees. If there’s metal that you can’t repurpose, there’s the option of selling it or making a tax-deductible contribution to a non-profit building supply company.

You can earn green points. A green demolition may qualify your project for LEED points or a related certification. Builders can also earn points by planning new construction with a future green deconstruction in mind.

Salvaging scrap metal is a time- and work-intensive process. When dismantling an aluminum plant, for example, our company harvested 35,000 tons of structural steel. This involved using steel shears to cut the larger scraps into smaller pieces for transporting. Then the smaller pieces must be gathered and separated from the rest of the construction debris — in many cases, this requires a crew to comb through the site and separate the materials by hand, which is dangerous as well as time-consuming. We’ve found the use of magnets to be the safest and most efficient way to extract scrap metal from a site.

One rookie error demolition companies commonly make is not properly sorting the different types of metal. It’s usually fairly obvious that any copper, aluminum or other precious metals should be separated. However, once these materials have been removed, many crews will simply gather the remaining metals into one load. That means heavy structural steel often gets mixed together with ductwork, metal wall studs, light fixtures and other less valuable metals. At the scrap yard, just a few pieces of these undesirable materials can diminish the value of the heavy steel as much as 20 percent — that’s $25-50 per ton. When you’re hauling 10-12 tons of scrap metal for resale, this can be a costly mistake.

For more information about scrap metal demolition, and site management, stormwater management and eco-friendly opportunities in the area, the Pacific Northwest Pollution Prevention Resource Center and the EPA provide a list of green building resources and certification programs available in Oregon and Washington.

Portland-based Elder Demolition has experience with scrap metal demolition, scrap metal recycling and LEED-certified green demolitions.

Area’s first commercial building made of cargo containers up for sale

In February of 2010, I wrote this story about an office building in Georgetown that was constructed of reclaimed cargo containers. The owner, Jay Stark, said it was the first project of its kind in the country.  I also produced this video-tour of the space at the time. Here is our story from Dec. 16 about the sale.

Now,  nearly two years later, the space is for sale for $1.5 million. Sadly, it was a foreclosure. I

haven’t spoken to the owners so I don’t know what happened but it’s too bad things likely didn’t turn out as planned.

The slight upside is that it will be really interesting to see who buys the site when it sells. I recently spoke to Evan Lugar of Kidder Mathews, who is representing First Savings Bank Northwest on the sale. He said the bank has owned the property since August. He also said it’s a tricky space to sell because it isn’t typical retail or commercial and is unique. He’s targeting creative businesses.

The building is made of 80 percent recycled materials by weight. The complex has two buildings, which are each made of six cargo containers that came from the Port of Seattle. They have halogen and fluorescent lighting, an efficient reverse-cycle chiller HVAC system, and windows with argon gas sandwiched between the panes for increased insulation. There is a rooftop deck with views of downtown Seattle and Mount Rainier.

Typically – the super green, innovative projects that have been built have been created with the intent of the owner using it for many years. (Houses don’t count). The greenest commercial projects I’ve profiled over the years have been built or are being built by the Bullitt Foundation, the U.S. General Services Administration, a consortium involving the city of Portland, universities or by firms that intend to stay in a space for a long time.

My point is: they don’t turn hands. Because of that, there isn’t much information about the resale value and market for super green projects in the U.S. created for a specific client. People hypothesize uber-green buildings hold their value better and that there’s more demand, but it’s hard to prove – without proof. No matter what, this is just one building. But the more sales we see, the more accurately we’ll be able to guage the true value of innovative sustainable buildings and whether it’s the LEED credential or a building’s inherent sustainability that translates as value.

As a sidenote, this is the second time spaces made of cargo containers or using “cargotecture” has been in the news in a week. Earlier this week, the DJC covered a new pilot project Starbucks drive though in Tukwila made of cargo containers. Here’s our story and here’s the story the AP ran based on our story.

Recycle your bike tubes this weekend and next

Performance Bicycle, a specialty bike retailer, is sponsoring a bike tube recycling drive to coincide with a Seattle expansion, a new store in Tukwila and a new look in the Lynnwood location. The drive runs the weekends of September 17-19th and September 24th-26th.

You know you have some old bike tubes laying around...
During that time, the Tukwila and Lynnwood stores will host the Bike Tube Blow-Out, during which people can bring used or blown-out inner tubes to the store and receive up to three $5 gift cards for the tubes they recycle. The event is sponsored by Performance and Liberty Tire, which will turn the tubes into mulch for playgrounds, athletic fields, railroad ties and highway asphalt. Press materials for Performance say Liberty collects and recycles nearly one-third of the nation’s annual scrap tire material.

The Lynnwood location is at 3225 Alderwood Boulevard. The Tukwila location is at 351 Strander Boulevard in the South Center Plaza.
