About Coffee Logs

A compact fire log for wood burners and multi-fuel stoves, Coffee Logs are sustainably made from recycled coffee grounds and they really turn up the heat. Burning 20% hotter and longer than kiln-dried wood, Coffee Logs help reduce greenhouse gas emissions and avoid the heavy carbon footprint created by coal.

Coffee Logs are made from waste coffee grounds collected from cafes, offices and instant coffee factories, and even airports, train stations and universities throughout the UK, giving your daily hit of caffeine a second life. In fact, each log is made from around 25 cups of coffee!

The UK alone drinks 95 million cups of coffee every day, fuelling not only the daily grind but also a growing amount of unnecessary waste. All that barista brilliance creates around half a million tonnes of wet coffee grounds typically headed for landfill, where they emit harmful greenhouse gases, including methane.

By recycling the nation’s cappuccinos into Coffee Logs heating briquettes, we reduce emissions by 80% compared to those grounds sitting in landfill, making these efficient logs a sustainable alternative for fuelling your fire without heating the planet.

Do Coffee Logs smell like coffee?

No, Coffee Logs smell similar to wood as they burn. Though some of our customers say you can smell coffee when you first open the bag.

How long do they burn for?

Coffee Logs heating briquettes will burn for approximately an hour when used in closed appliances with well-managed air flow, such as multi-fuel stoves or wood burners. It’s best to consult your appliance guidelines to optimise the burn time. We recommend adding no more than three coffee fire logs at a time as they kick out a lot of heat. In fact, Coffee Logs burn 20% hotter and longer than kiln-dried wood logs.

Where are the coffee grounds from?

The waste coffee grounds come from coffee shops, offices, restaurants, instant coffee factories and even universities, airports and train stations around the UK. With the help of waste management companies, we collect and recycle thousands of tonnes of coffee grounds every year. We currently collect from businesses only. But if you’re looking for something to do with your home waste coffee grounds you can use them as fertiliser for your garden, or even as an ingredient for a homemade facial scrub.

Can I use Coffee Logs on a BBQ?

Coffee Logs are the perfect fuel log for warming your home in a wood burner or multi-fuel stove. They are not suitable for barbecues or other open fire cooking.

How do they help the environment?

Recycling waste coffee grounds into Coffee Logs helps reduce greenhouse gases, reduces waste and gives your latte a useful second life. Typically, coffee grounds go to landfill where they emit methane, a greenhouse gas 34 times more potent than carbon dioxide. By recycling coffee grounds into Coffee Logs, we generate 80% less emissions than if the grounds are sent to landfill, and we provide a sustainable alternative to coal briquettes and imported wood logs.

Is the packaging recyclable?

Yes, Coffee Logs are packaged in paper that is fully recyclable in the UK. Or it can be used as your firelighter!

Instructions for burning

Coffee Logs are the ideal fuel briquette for use in closed appliances such as wood burners and multi-fuel stoves.

For the perfect Coffee Logs fire:

  1. Place firelighters on appliance bed and cover with kindling. We recommend using sustainable firelighters where possible.
  2. Add two or three Coffee Logs.
  3. Light the firelighters and let the fire establish itself.
  4. When the fire is established, add more Coffee Logs as required. We recommend no more than two or three at a time, though. They kick out a lot of heat!
  5. Coffee Logs will burn best when undisturbed. Avoid prodding or stoking them.

Coffee Logs can be used on their own or together with wood logs. Remember to always follow your appliance manufacturer’s guidelines for safe and efficient burning.

Safety Precautions

  • Always follow the specific guidelines for your appliance, and never leave it unattended when you’ve got a fire going.
  • Store your Coffee Logs in a cool, dry, well-ventilated area, and at a safe distance from your appliance. After all, they are combustible.
  • Coffee Logs are not suitable for barbecues or other open fire cooking.
  • Coffee Logs contain a high amount of caffeine, which can be potentially harmful to humans and animals if ingested. It’s best to keep them out of reach of children and animals and to seek medical advice if swallowed.


Each bag of Coffee Logs contains 16 Logs and weighs approximately 8kg, with a convenient handle to make it easily portable.
