Earth Flow Referral Program
The Earth Flow is America’s leading industrial in-vessel composting system, with more than 15 years of successful on-site composting for campuses, community organizations, municipalities and farms. The Earth Flow is ideal for sites that need to process between 15 to 200 tons of material per month.
How the Earth Flow Referral Rewards Program Works
Since 1992, our business has grown primarily through word of mouth and referrals from happy customers. We want to thank everyone for helping us grow our impact, and accelerate it going forward. As of May 2025, we are now offering a significant reward to people who send us new Earth Flow referrals.
If you know someone who might be interested in composting with the Earth Flow, GMT will offer you a $1,000 cash reward, or a $1,500 purchase credit for a referral that leads to a sale!
How to Send Referrals to GMT
Simply send an email introduction to the person you are referring to GMT with [email protected] copied on the email. Please include the person’s full name in the email body and give them a quick summary of why you think they should consider an Earth Flow.
We will then follow up with them by email to see if they are interested in more information. We will not spam them, they can opt-out of receiving e-newsletters from us at any time. When they purchase an Earth Flow, you will be rewarded for introducing us to them. It's that easy, just a simple email introduction is all it takes.
“The Earth Flow In-Vessel composting system is one of the first of its kind in Hawai‘i and will alleviate problems of odors, emissions, and leachate commonly associated with composting. The compost machine can process up to 1,000 pounds of food scraps and green waste per day. Even better? With this machine, we are able to produce rich, healthy compost twice as fast as the traditional method!”
