About Coffee Logs

For many of us a cup of coffee from the local shop is a daily ritual. In fact, the UK drinks 98 million cups of coffee every day. Yet few of us know what happens to the coffee grounds once they’ve been brewed. Hundreds of thousands of tonnes of spent coffee grounds are wastefully thrown away every year.

We collect these spent grounds from coffee shops across the country and give them a second life as Coffee Logs. From independent cafes to nationwide chains. Not forgetting restaurants, office blocks, airports, universities, and instant coffee factories. We process and dry the grounds before compressing them into these efficient, sustainable fire logs for your wood burners and multi-fuel stoves.

Do Coffee Logs smell like coffee?

No, Coffee Logs have a neutral aroma. We think they 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.

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 or in a firepit?

Coffee Logs are the perfect fuel log for warming your home in a wood burner or multi-fuel stove. They are not designed or recommended for barbecues, firepits, chimineas, or other outdoor fires.

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, used coffee grounds are wastefully discarded. By recycling coffee grounds into Coffee Logs, we generate 130% less emissions than if the grounds are sent to the standard disposal method, and we provide a sustainable alternative to coal-based fuels and imported wood logs.

Is the packaging recyclable?

Yes, Coffee Logs are packaged in plastic-free paper that is fully recyclable in the UK.

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 plenty of kindling. We recommend using sustainable firelighters where possible.
  2. Light the firelighters, close your appliance doors and open the air vents to get a good flame going.
  3. When the fire is established and hot, add 2 or 3 Coffee Logs facing front to back. We recommend no more than this at one time, though. They kick out a lot of heat!
  4. Once the Coffee Logs are lit, adjust the air vents again and then sit back and enjoy.
  5. Coffee Logs will burn best when undisturbed, so 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 a fire unattended.
  • 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 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.
  • Coffee Logs are not recommended for barbecues, fire pits, chimineas, or other outdoor fires.
  • Coffee Logs are not authorised for burning in Smoke Control Areas.


Each bag of Coffee Logs contains 16 logs and features a convenient handle to make it easily portable.
