Philippine company makes coolers made from coconut husks.

A bit on the expensive side but I would definitely buy one.  My wife seems to go thru about four styrofoam coolers a year.

(CNN)Cheap to make, water-resistant and insulating, foamed polystyrene is the go-to material for packaging in markets and food stores around the globe.

But it also breaks apart easily, and the same qualities that make it excellent for keeping food fresh and cool also make it particularly bad for marine ecosystems.
That's why one Philippines-based startup has been working on an affordable alternative that it says is better for the environment, and for food producers working within tight profit margins.
Fortuna Cools, founded in 2018 by a pair of Stanford University students, saw an opportunity to use another abundant source of waste in the Philippines: coconut husks.
The Philippines is one of the top producers of coconuts and coconut products in the world, and every year, an estimated 9 billion husks are burned or left in the field, where they can take years to biodegrade.
Fortuna Cools says it can produce 1,000 of its coconut-husk coolers each month. 

This durability gives the coconut husks some of the same insulating properties as polystyrene, says Julius Bucatora, operations manager of Fortuna Cools.
Working with Coco Technologies Corporation, the startup developed technology to turn the coconut husks into insulated coolers. First, the husks are broken down into fibers, air-dried, and then pressed into thick boards that make up the box lid and sides.
These coconut boxes are a double win, as it provides extra income to the 30 local coconut farmers it works with, says Bucatora. Each box costs around $20, according to the company — around two to three times the price of polystyrene coolers — but the company says the box lasts for up to a year and will pay for itself in the first three months.

Interesting.  After their insulation properties break down, I bet it could be used as a raised garden bed until it totally deteriorates.

They have raised over $1 million so far. Not bad seed money for a Filipino startup. I wonder how good the cooler really works.

We have them dangling around our shack, being used as hanging baskets for plants.
