4 Companies Reusing Coffee Husk for Eco-Friendly Innovations

Coffee is a powerful source of energy and health benefits, but the journey from plantation to mug involves an energy-intensive process that produces significant waste, particularly coffee husks. Ethiopia alone discards about 192,000 tons of coffee husk annually, as reported in 2017. Improper disposal of coffee husks can lead to environmental damage and health issues, including respiratory problems, eye irritation, and nausea.

To address this issue, four forward-thinking companies are turning coffee waste into valuable resources:

1. Husky Energy and Technologies: Transforming coffee husk into biomass

Husky Energies & Technologies, established in 2021, is driven by the challenges coffee farmers faced in disposing of coffee husks. The duo developed machines that can transform coffee husks into biofuels, specifically pellets and briquettes, offering an eco-friendly alternative to traditional fuels. Husky’s biofuels reduce smoke emissions by an impressive 90%, combating household air pollution, a major health hazard in developing countries.

2. Huskee: Innovating in the coffee cup industry

An average coffee enthusiast generates about three kilograms of coffee husk waste annually, while about 2.5 billion disposable coffee cups are used each year globally. Australian startup Huskee has innovated by creating coffee cups and lids from discarded coffee husks. Through a Kickstarter campaign that raised US$114,000 between 2017 and 2018, the Sydney-based startup has collaborated with farmers in China’s Yunnan Province, a specialty coffee region, to source coffee husk for their durable, ceramic alternative cups.

3. Ford: Turning coffee husk to build car parts

Ford and McDonald’s are using coffee chaff—the husk of the coffee bean—to manufacture car parts. This initiative, involving Canadian-based Competitive Green Technologies, repurposes coffee chaff from McDonald’s suppliers into a composite material for automotive components like headlamp parts, interior elements, and under-hood components. The process involves exposing the coffee chaff to high temperatures in low-oxygen environments and combining it with resin, plastic, and additives to create pellets that can be molded into different shapes.

4. Woodpecker: A sustainable solution to Colombia’s housing crisis

In Colombia, Woodpecker skillfully manufactures lightweight, prefabricated panels combined with recycled plastic. These panels serve as the foundation for constructing homes and classrooms, being cost-effective and designed for straightforward, do-it-yourself assembly. The construction materials champion eco-friendliness and their resistance to pests and moisture make them an excellent choice for low-income housing across Colombia’s diverse climates.

Repurposing coffee husks is not just innovative but also a bold step forward in sustainable business practices. Companies like Husky Energies & Technology, Huskee, Ford, and Woodpecker are showing the world that environmental responsibility and economic success can go hand in hand. This shift towards using what was once waste embodies the essence of a circular economy, reducing environmental impact while fostering new markets and opportunities.
