Home » rPlanet Earth PET Plant to Produce 100% rPET Products
A new plant owned and operated by green tech company rPlanet Earth (rplanetearth.com) will launch this month in Vernon, Calif., to make about 75 million pounds a year of two product types from 100 percent recycled polyethylene terephthalate (PET). The facility will produce forms to make both beverage containers and food packaging. It will also combine several processes normally done in a few facilities under one roof, cutting emissions and, potentially, cost for finished products.
rPlanet will make preforms for beverage containers, and it will make thermoforms for containers for produce, deli, bakery and other ready-to-eat foods.
Traditionally, PET bales have been sorted, ground and washed at one facility. From there, flake typically goes to another company that decontaminates it and turns it to pellet, bringing it to the Food and Drug Administration’s required specs, whether for food containers or bottles. Then, material would typically have gone to another location, either a plant to make preforms or a plant to make sheet for thermoforms.
“These intermediate transportation steps create greenhouse gas emissions and mark up between facilities, adding to the cost of materials,” he says. “But we take the process from raw material through to preform or thermoform under one roof for the lowest carbon footprint possible," said Robert Daviduk, co-CEO of rPlanet Earth.
At rPlanet there are two paths. Along one path, the material is conveyed to a sheet extruder. From here, rPlanet can take sheet and convert it into thermoform in a separate machine that presses and molds it to make different forms for different applications.
“For preforms, it goes into an injection molding machine. So, the two paths enable us to make two different products,” says Daviduk.
The postconsumer bales of PET will be run through optical sorters to ensure that what comes out is 100 percent pure PET.
The plan is to prove out the first line and then install a second parallel line, both in the 300,000-sq. ft. Vernon plant. A later goal is to build three or four similar plants across the U.S., concentrated in the Midwest, Northeast/mid Atlantic, Southeast and Texas.
Developing the project was a five-year endeavor, from idea inception through design and planning, to setting up with equipment manufacturers, to installation.
“What we learned through the process is that we have a lower carbon footprint. And we learned different ways to take what are now manual paths to automate in order to make the plant efficient and increase output capacity,” says Daviduk.
