[00:00.40] It's the most popular drink worldwide. According to the British Coffee Association, approximately two billion cups of coffee are consumed every day.

[00:11.03] But after the beans have been picked, roasted and brewed, the grounds are often disposed of as waste.

[00:18.47] With the environment and resource consumption such hot topics at the moment, wouldn't it be great if we could reuse this waste to make something useful? Well, you can.

[00:31.48] The company OCHIS manufactures sunglasses.

[00:36.00] Max Havrylenko, founder of the company, was searching for an alternative substance to plastic.

[00:46.36] He wanted to 'solve the problem of plastic use and overconsumption', he told the BBC. OCHIS fuses the grounds with vegetable oils, forming a bond.

[00:53.00] These are pressed into plates which are durable and flexible. These are then cut into the arms and frames of the glasses.

[01:00.70] "Don't worry," he says, "They won't dissolve in the rain."

[01:05.48] Rosalie McMillan, a London jeweller, uses recycled coffee grounds along with gold and silver to make handcrafted jewellery.

[01:13.98] She mixes the coffee with oils and subjects it to heat and pressure to create a compound she calls 'Çurface'.

[01:21.95] Her website claims it has a 'beautiful surface quality and texture' with similar properties to hardwood.

[01:29.65] What about a coffee cup made from them? Kaffeeform is a German-based company that transforms used grounds and renewable plant-based raw materials into a durable composite.

[01:41.34] This is shaped into a variety of containers and polished and finished, ready to be sold.

[01:47.71] So, you can drink your coffee from a cup made of coffee.

[01:53.03] And it doesn't stop there. Even without a factory, you can make use of coffee grounds. They make excellent fertiliser.

[02:01.26] You can exfoliate with them, or mix them with water to make a sepia-toned paint.

[02:05.78] And the list goes on. So next time you finish your morning cup, save the grounds.
