A Cool Use for Recycled Glass

0
Some outdoor naturescapes are enjoying a little extra sparkle – with assistance from old beer bottles and other recyclables. Bits of repurposed glass, in jewel-like nuggets, provide a decorative accent at the base of hedges, potted greens and other types of landscaping.

The product, formed by grinding various types of recycled glass, is sold at some landscape shops around the nation, and also via online retailers. In Austin, Texas, the solid waste department gives the stuff away for free.

Depending on the supplier, the glass pebbles are available in an assortment of hues. Also, the product, sometimes referred to as “glass mulch,” is tumbled to round out sharp edges.

ASG Glass in Utah produces landscape glass in a wide variety of individual colors and blends. Some are the natural color of the bottle or window being recycled, others feature added pigment, according to ASG Glass president Berkeley Booth.

According to EnviroGLAS, over 40 billion glass bottles are made every year. Maybe some of them will end up your backyard! - enviroglasproducts.com

Not Just for Your Backyard

The array of colors allows gardeners flexibility for customized designs. A football team ordered a truckload of green and white glass, which probably will be used as a team logo, Booth said. He also noted that often, blue hues (such as the Caribbean mix, featuring soft sea tones and clear pieces) are used to form a faux stream or pond that winds along a portion of the landscape.

At a flower show, someone created a diamond design with pink glass, and an art center in Arizona created a striking look for cactus planters by lining each one with a different color of glass.

The price for the ASG Glass products depends on the color and quantity. The 25-pound bags, for example, are between $20 and $108. Usually, about seven pounds of glass is needed per square foot.

Online supplier is EnvrioGLAS, in Plano, Texas touts another environmental benefit of the recycled product. “Glass mulch does not absorb water like wood mulch, so the water goes where it is intended – into the plants – and even less water is used.” Most of its products are sold in 50-pound bags for around $35.

Charlie Nardozzi, senior horticulturist for the National Garden Association in Vermont, said he regards the product as primarily a decorative feature. Unlike organic mulch, glass doesn’t break down and fertilize the soil. He said he’s not sure if it offers other mulch functions, such as keeping the soil cool and moist. It does, however, offer an interesting aesthetic value.

“It’s really kind of cool,’’ he said. “It’s really more of an artistic expression.”

For those who want to express their artistic personality through glass mulch for free, the city of Austin gives away crushed glass at its landfill. Of course, the pallet is a bit more limited. The city of Austin’s decorative glass is a blend of the containers they collect – clear, brown and green.

    I really wish there was a place to recycle glass in my Alpena MI community! I recycle everything I can, but they don’t take glass.
    Our recycler tells me that they make glass-phalt for paving but he doesn’t have a contract for it. His facility is limited for space so he can’t store enough at his site to make it desirable for a large company to accept his/our glass.
    I like the idea of using glass decoratively, but couldn’t the glass also be melted down and re used for new glass bottles too? Who is doing that & how can I get my recycle center in contact with them.
    Also why doesn’t the government reimburse or help make it feasible for glass to be recycled?

    I have a post about the recycled glass mulch available in Austin on my gardening blog. I love this stuff! I have made two pathways with it through my garden, and I plan to get more this year. It’s a great way to use the recycled glass from the city, and it always gets comments from garden visitors.

    I like to know if there is a place in Michigan to buy the blue recyle glass?

  • Debbie Schur

    What is the process for recycling glass bottles? I have been saving green & blue bottles for years thinking that I could find a way to crush them and smooth the edges to use in my garden for decoration. How is the glass treated so that edges are smooth?

    There is an excellent crusher, made by Andela, that crushes the glass so well that when you squeeze the crushed glass in your hand (by making a fist), you will not get cut. Generally, however, the cost of a “real” crusher is too high for an individual, but not for a larger community. Talk to your Dept of Public Works or Recycling Coordinator about accepting glass and crushing it for decorative purposes. A municipality could probably accept it for recycling and then sell it to landscapers if they kept the colors separate.

    Also, I have high praise for EnviroGlas….they have beautiful products and wish they would start a plant up here in New England!

    does anyone know how to contact the # in Austin about recycled glass? thanks for any info…

  • Carri Pohl

    Looking for more information on Austin’s recycled glass program. I am looking into using this type of material for my garden path.

  • Joyce Horvath

    This is for Caroline.
    There is a place in Michigan that sells the glass. It is called Grand River Recycled Glass. I don’t know exactly where it is, but the website is http://grrecycledglass.com You can probably get more information from that site.

    Does anyone know if it’s possible to commission a sculpture, or an interior design element/feature from recycled glass. If they can be blown into glass pebbles, can they blow them into other stuff?

    This sound like a good idea, and a beautiful one. Probably would use this idea in my garden, but, wouldn’t glass mulch be too hot for the plants, specially during the summer?

    I have buried whole wine bottles (no full!) upside down, leaving about three inches showing, as a border for one of my gardens. It was really cool too.
