Drink Your Coffee Out of a Cup Made From Coffee Waste

Your coffee habit isn’t exactly good for the environment. For one thing, 30 to 50 percent of the original coffee plant harvested (by weight) ends up as agricultural waste, and there aren’t many uses for coffee husks and pulp. While coffee pulp can be made into flour, and in Ethiopia husks are used to brew a type of coffee called bruno, typically most of the byproducts of your morning coffee go to waste.

Huskee has another use for coffee husks. The company makes stylish coffee cups, returning coffee back to its original home inside the husk, in a sense. The dishwasher-friendly and microwavable cups are made of husks from coffee farms in Yunnan, China. The material won’t burn your hands, but it keeps your coffee warm as well as a ceramic mug would.

Designed for both home and restaurant use, the cups come in 6-ounce, 8-ounce, and 12-ounce sizes with saucers. The company is also working on a lid so that the cups can be used on the go.

Huskee estimates that a single coffee drinker is responsible for around 6.6 pounds of husk waste per year, which doesn’t sound like much until you begin to consider how many coffee lovers there are in the world. That’s somewhere around 1.49 million tons per year, according to the company. Though coffee husks are sometimes used for animal feed, we could use a few more ways to recycle them. And if it happens to be in the form of an attractive coffee mug, so be it.

A four-pack of cups is about $37 on Kickstarter. The product is scheduled to ship before February 2018.

An Eco-Friendly Startup Is Converting Banana Peels Into Fabric for Clothes

A new startup has found a unique way to tackle pollution while simultaneously supporting sustainable fashion. Circular Systems, a “clean-tech new materials company,” is transforming banana byproducts, pineapple leaves, sugarcane bark, and flax and hemp stalk into natural fabrics, according to Fast Company.

These five crops alone meet more than twice the global demand for fibers, and the conversion process provides farmers with an additional revenue stream, according to the company’s website. Fashion brands like H&M and Levi’s are already in talks with Circular Systems to incorporate some of these sustainable fibers into their clothes.

Additionally, Circular Systems recycles used clothing to make new fibers, and another technology called Orbital spins those textile scraps and crop byproducts together to create a durable type of yarn.

People eat about 100 billion bananas per year globally, resulting in 270 million tons of discarded peels. (Americans alone consume 3.2 billion pounds of bananas annually.) Although peels are biodegradable, they emit methane—a greenhouse gas—during decomposition. Crop burning, on the other hand, is even worse because it causes significant air pollution.

As Fast Company points out, using leaves and bark to create clothing may seem pretty groundbreaking, but 97 percent of the fibers used in clothes in 1960 were natural. Today, that figure is only 35 percent.

However, Circular Systems has joined a growing number of fashion brands and textile companies that are seeking out sustainable alternatives. Gucci has started incorporating a biodegradable material into some of its sunglasses, Bolt Threads invented a material made from mushroom filaments, and pineapple “leather” has been around for a couple of years now.

Apeel
New Plant-Based Coating Can Keep Your Avocados Fresh for Twice as Long

Thanks to a food technology startup called Apeel Sciences, eating fresh avocados will soon be a lot easier. The Bill Gates–backed company has developed a coating designed to keep avocados fresh for up to twice as long as traditional fruit, Bloomberg reports, and these long-lasting avocados will soon be available at 100 grocery stores across the Midwestern U.S. Thirty or so of the grocery stores involved in the limited rollout of the Apeel avocado will be Costcos, so feel free to buy in bulk.

Getting an avocado to a U.S. grocery store is more complicated than it sounds; the majority of avocados sold in the U.S. come from California or Mexico, making it tricky to get fruit to the Midwest or New England at just the right moment in an avocado’s life cycle.

Apeel’s coating is made of plant material—lipids and glycerolipids derived from peels, seeds, and pulp—that acts as an extra layer of protective peel on the fruit, keeping water in and oxygen out, and thus reducing spoilage. (Oxidation is the reason that your sliced avocados and apples brown after they’ve been exposed to the air for a while.) The tasteless coating comes in a powder that fruit producers mix with water and then dip their fruit into.

According to Apeel, coating a piece of produce in this way can keep it fresh for two to three times longer than normal without any sort of refrigeration or preservatives. This not only allows consumers a few more days to make use of their produce before it goes bad, reducing food waste, but can allow producers to ship their goods to farther-away markets without refrigeration.

Avocados are the first of Apeel's fruits to make it to market, but there are plans to debut other Apeel-coated produce varieties in the future. The company has tested its technology on apples, artichokes, mangoes, and several other fruits and vegetables.
