More and more couples want to go green for their weddings. According to Pinterest, searches for low-waste weddings are up 235% in the past year.

One popular wedding tradition -- showering the newlyweds with confetti and other festive items -- is getting a sustainable twist.

Dating back to Roman tradition, guests throw rice at couples to symbolize fertility and prosperity. There was a rumor that rice was bad for birds, but that's been debunked, so feel free to use rice to celebrate your I Do's. Consider birdseed, too.

*Confetti

"Couples embarking on beautiful lives together are becoming more and more conscious of the impact of their celebration, and it's a win-win for the environment," says wedding planner and designer Bree Carroll of B Carroll Events. "Sustainable products and practices are taking the spotlight. This includes reducing the amount of waste or using biodegradable, plant-based or recycled items."

One of Carroll's couples, for example, used biodegradable confetti purchased on Etsy, instead of traditional

Eco-friendly confetti breaks down quickly and is available in a variety of colors, shapes and sizes.

*Flowers

Get showered with flowers.

"Lavender is an incredible option as it smells great, travels well when thrown in the air and provides a beautiful color," says Brian Worley, creative director and owner of B. Worley Productions.

He says dried flowers, petals and green leaves are options, too. They can color coordinate with a wedding color scheme, plus they biodegrade back into the Earth.

Plantable seed confetti, available in shapes like hearts and flowers, is embedded with herb or wildflower seeds.

"As the guest throw the seeds, the hope is that the seeds will eventually plant, and you will have flowers," he says.

*Taking Flight

Show your commitment to a sustainable send-off by repurposing old maps as paper airplanes. Enlist your wedding party to help fold and decorate the colorful planes. The designs are perfect for couples who like to travel or who are going on their honeymoon.

*Dance

You can cha-cha-slide out of the party, too! Kristie Hinchman, event sales manager at Hyatt Centric Key West Resort and Spa, says many couples choose to have a send-off song and dance instead of throwing confetti. "It all depends on the personalities of the couples and then figuring out a way to visually or experientially tap into that passion without harming the environment," she says.

*Avoid Balloons

While balloons may be fun, environmentalists don't recommend a balloon arch or balloon release. The Environmental Health Nature Center says mylar balloons are a definite no-no because they're not biodegradable. Some latex balloons are biodegradable, but the breakdown process can take anywhere from six months to four years. Along the way, they're a danger to animals, who can eat the balloons or get trapped by them.

*Bubbles and Ribbons

Make sure you know if your venue has any rules about throwing confetti or participating in other cheerful traditions.

"Before you start discussing what to do, check with your wedding or venue planner to best understand any destination restrictions," says Hinchman, who often sees guests blowing bubbles and waving ribbon wands.

Some venues, such as churches, may require you to not throw anything or to sweep the remnants right away. Get the rules and requirements in writing so you know the specifics. Then you can make a plan for how to say "hooray" visually and salute the happy couple on their special day.

Don't forget to alert the photographer of your colorful send-off. Confetti, bubbles and other tossable fanfare make great photo opportunities!
