The first biodegradable water bottle is coming – Cove

The Cove plans to launch the biodegradable bottle, a thin, sturdy, eggshell-white round with a matching closure. It feels familiar. “If somebody gave that to you,” presented Alex Totterman, Cove’s founder and chief executive, “you likely would have no thought that that wasn’t a plastic bottle.”

First “fully biodegradable” bottle of water

If somebody does offer you this bottle, it would be a fantastic achievement. The researcher has spent many years and money attempting to substitute everyday packaging with natural materials that don’t spoil the Earth. So far, that’s shown us little further compostable straws. But the challenge hasn’t hampered Cove’s five-year journey to creating the first “fully biodegradable” bottle of water. Totterman says Cove’s creation will finally hit stores at $2.99 a pop in the coming months.

In February 2019, Cove’s Biodegradable bottles came in stores later that month. But didn’t. In October 2020, Totterman told the Los Angeles Times that his bottles were arriving after the new year. Still nope. Pandemic uncertainties and supply chain bottlenecks have often derailed the startup’s projects, as has the chemistry interested in its mission.

Cove’s bottles begin in kitchens. RWDC Industries, a chemical supplier with US headquarters in Georgia, first gathers cooking oil from cafes and ferments it into polyhydroxyalkanoates, or PHA, a polymer represented to dissolve in water or soil without any toxic remains. RWDC ships this outcome to Cove’s warehouse north of Los Angeles, where it comes as tiny round pellets that glimpse and feel like bits of Styrofoam. RWDC — the only PHA supplier of Cove’s that the busniness startup would name — adds secret ingredients to its concoction. Still, Blake Lindsey, the company’s chief commercial officer, said that there’s nothing synthetic involved.

PHA pellets

From there, the PHA pellets transfer to Cove’s 25,000-square-foot factory. They are shipped through machinery to vacuum pack, sift out metal, stretch, cut, and mold the material into a hollow canister for water—print on each bottle (“Cove’s plastic-free, renewable bottles”). The ink, produced from algae, is represented to biodegrade, too. Water from a cleansing plant nearby is poured in. By Cove’s calculations, its bottles will disintegrate in sand and water in under five years.

After beginning in 2018, Cove cycled via at least one direction to make its bottles that didn’t pan out. When the firm chose to open its factory in early 2021, Cove quickly found the unpredictability of its Goldilocks material. If PHA gets too freezing, it evolves too brittle; if it’s too hot, it turns soft. During one test run, the element overheated, and Cove’s factory floor burst into steam and an intense aroma of caramel that one early employee defined as “especially vivid.” 

Every aspect of the bottling tools Cove bought also required to be modified to handle the inconsistent material, and most took permanently to show up. Steel pipes to assist the pellets between machines and a temperature detector tool didn’t come for more than a year. Still today, one of Cove’s 12 workers manually sorts bottles rolling off the assembly line because a motorized sorter is en route. It was promised to be here in April,” explained Cove’s vice president of technology, Jim Shepherd, shouting over the machine din. “We’re now in October and waiting on a robot.”

When Cove began production, it took PHA pellets to the lab to experiment with their physical properties, planning to stay on the results before developing them into bottles, said Agnes Steckler, Cove’s research director. So the organization built Steckler her lab, a space with eight machines to calculate the PHA’s resilience, melting points, and molecular weight. The lab sent on the startup more stretch and “millions of dollars,” Totterman said. But it was worthwhile: “We had to take a step back to take two steps forward.”
