About us

Tech-enabled. Data-driven. Service-first. It's a better way to manage waste.

Company

We are Waste Harmonics Keter—your partner in handling complex waste operations.

What started in 2001 as a regional tech-focused waste services company, has evolved into a national partner to some of the largest companies in the country.

Growing steadily for nearly 25 years, we have become the choice provider for managed waste services by pairing high-touch, white-glove customer service with data-driven, tech-enabled programs. From developing proprietary monitoring technology to linking arms with other industry leaders to strengthen our operations, we have a storied history of doing what's needed to serve our customers well.

Today, we are honored to support more than 70,000 sites across North America with full-service waste and recycling solutions. Now with a refreshed brand launched in 2025, we remain focused on what we’ve always done best: listening to our customers, solving problems proactively, and delivering smart, sustainable waste solutions that scale.
