GWT works with waste collection sites, municipalities and others to process their nonhazardous green waste swiftly.

Troubled Green Waste
We work with troubled green waste, non-chemically treated wood scraps and waste from construction sites and disaster cleanup efforts as well as traditional municipal green waste such as grass, leaves, tree trimmings, etc. 

Beyond Compost
Our microbial process converts green waste, even palm fronds into a carbon stable and high-value soil in just a few weeks rather than months or even years. We eliminate the expenses of labor and mechanical turning!

We’re Committed to Your Success

We focus on tailoring solutions to your business needs utilizing advanced microbial technology to rapidly convert green waste into valuable soil.  And we minimize landfill usage while reducing operating and energy costs.

Collaboration that Works

Take advantage of the fast-processing time of GWT’s technology to free up space to accept more waste, thereby increasing tipping fee revenue to enhance your overall business success.
