Composting is a great way to deal with food waste naturally, but there's an even faster method that can convert solid waste into nutrient-rich greywater — and do it within 24 hours. The ORCA Green Machine is a high-tech waste digester that's now in use at the Aflac cafeteria to keep thousands of pounds of waste from ending up in landfills each year.

Aflac has a corporate goal to recycle at least 75 percent of its solid waste. Now, with the ORCA Green Machine, the company can recycle its food waste, too. In this video, Aflac employees discuss how the ORCA machine works, and the impact that it can have on the company's goals as an environmentally responsible corporation.

Using microorganisms to break down the waste, the ORCA Green Machine reduces up to 2,400 pounds of garbage every day, turning it into a nutrient-rich liquid similar to compost tea that can be used for irrigation or can be safely disposed of through the sewer system.

Here's how it works: first, food waste is added to the machine. Water is added periodically to keep it moist. The waste is turned consistently inside the machine, and microorganisms are sprayed into it daily, breaking the waste into liquid. The ORCA machine has been installed at the Aflac cafeteria for four months, and has the potential to divert up to 60,000 pounds of waste from the landfill annually.


S1: Landfill diversion is important to us, because as an environmentally-responsible corporation, we want to reduce the amount of waste that we send to the landfill. We have a corporate goal to recycle at least 75% of all of our solid waste. Now, with the advent of our ORCA machine, we are even recycling our food waste.

The ORCA Green Machine, ORCA stands for organic refuse conversion alternative. It is a machine that uses enzyme activity to convert solid food waste into environmentally-friendly, nutrient-rich, grey water that's disposed through our sewer system.

S2: It uses the same principle as outdoor composting but it does it much, much faster, usually within a 24-hour period. The first thing you do is you add the food waste, anything that you can eat, can be put into the digester. Then water is added periodically, to help keep the food waste moist. Then the waste is turned consistently inside the machine. Then micro-organisms are sprayed into the machine daily. The micro-organisms eat the food waste and breaks it down into a liquid. The by-product of the machine is a grey-water material that can be used for irrigation or put into a sewer system.

S1: The max potential for recycling, based on our numbers from last year, would be about 60,000 pounds of waste, diverted from the landfill.

S3: The ORCA Machine has been in place for approximately four months now. Eventually, we intend to implement that program, also at the main campus and I think that would be a success story to tell.

S1: Environmental issues are important to Aflac, as a good corporate citizen, we've always prided ourselves on being good corporate citizens. This is a way that we can extend and expand on our efforts to be a better partner, not only to our shareholders, our policy holders, but also to the environment.

Food waste gets the high-tech treatment at Aflac with ORCA machine
Installed at one of Aflac's cafeterias in Georgia, the ORCA Green Machine diverts food waste from the landfill, turning it into nutrient-rich greywater.
