Casella Waste Systems Inc. has purchased a mobile renewable power station for mobile power and clean energy marketing at Casella promotional events.

Rutland, Vt.-based Casella purchased the station from Rochester, N.Y-based Arista Power Inc., which makes custom-designed power management and renewable energy storage systems, the company said in a news release.

The stations are designed to replace diesel generators in remote locations in a cost-effective manner with clean energy. The stations are customized to optimize available renewable energy.

"We recognize that our industry is evolving toward a model that rewards an approach to resource renewal and sustainability," John Casella, Casella Waste chairman and CEO. "We are creating value from this shift by performing at the highest operational level today, and developing resource transformation business opportunities beyond the traditional waste consumption model that meet the emerging environmental sustainability needs of our customers today and tomorrow."
