The recycling of coffee grounds is nothing new, and coffee workshops have introduced the different uses of coffee grounds in many articles. The first step in reusing coffee is to dry the coffee grounds, because undried coffee grounds are very easy to mildew.

Four students from the Singapore Institute of Technology planned to reuse coffee grounds, so they dried the recycled coffee grounds in a pan, but the coffee grounds suddenly caught fire during the roasting process. In addition, it inspired several already environmentally friendly science and engineering students to develop a variety of environmentally friendly products made from coffee grounds, including solid coffee grounds fuel, candles and decorative trays.

After a large number of experiments, they found that coffee grounds under a certain list can become combustible. So this group of students used this idea to participate in the 2021 Maple Tree-Singapore Chinese Chamber of Commerce Spring to Riverside programming Marathon Entrepreneurship Competition, and successfully stood out among the 11 teams and won the most innovative award.

The team also received a bonus of 2000 yuan and start-up capital of 5000 yuan, which can be used to develop goods and related services. It is understood that the award-winning team will have the opportunity to sell their goods at "Spring Riverside 2022" held in Marina Bay Garden from January 30 to February 6, 2022.

It is understood that the theme of the "Fengshu-Singapore Chinese General Chamber of Commerce Spring to Riverside programming Marathon Entrepreneurship Competition" is "Innovation helps Sustainable Development". Coffee grounds as a growing waste, and the use of coffee grounds to find "solid candles" and other derivative products are very good to solve the growing problem of coffee waste.

There are numerous examples of coffee grounds as a new source of energy. You can open the door to the new world of coffee grounds through the link below.

Today, I would like to share with you more stories about coffee grounds.

Revive from the UK is formed by a group of people who love nature and environmental protection. Most of the people in the team are biologists and chemists. The mission of the team is to "give new life to waste materials and create a world without waste."

Since 2019, the team has removed 20 tons of coffee grounds from landfills, reducing carbon emissions by 36 tons. In 2021, 100 tons of coffee grounds will be reused. According to officials, after a long period of research, they have been able to extract valuable palm oil from coffee and tea.

When it comes to turning coffee grounds into fuel, Coffee Coal in 2015 is even more ingenious in using coffee grounds to become "coffee charcoal". According to the relevant video released by Coffee Coals on the oil pipe in June 15, the principle of carbon production is to use a biomass press to press the shelled coffee peel, corn husk, leaves and feces into bricks to make energy-saving "coffee charcoal" to facilitate the daily life of Guatemalan people.

In fact, in foreign countries, the collection of coffee grounds has gradually become a systematic process. Since 2004, Bruce Bratteli (Bruce Bratley) founded First Mile (first mile), a team dedicated to protecting the environment, helping and representing customers to make waste solutions that help protect the planet, including the recycling of coffee grounds.

Waste coffee grounds are transferred from landfills to biofuels and essential oils that reduce greenhouse gas emissions. According to the website, the heat output of coffee grounds is 20% higher than that of wood, but the hand speed is 18% slower, making it a more durable fuel.

Have you ever thought about the best way to deal with coffee grounds? It would be cool if all the non-recyclable commercial waste could be used in the recycling of green energy.
