I've looked at this company several times but never taken the plunge. They get good reviews. My only concern is the Lekto supply chain is opaque, they don't say where they source their raw materials from. ANy ideas?

Much wood sold on-line in the UK comes from Eastern European forests. There's a carbon cost in transporting it, and in the case of dehydrated waste wood manufactured products such as pulped, chipped, compressed and dehydrated logs, quite a high carbon cost to manufacture. On the flip side, it provides a use for by-product material that would otherwise probably end up in landfill as waste. I always try to buy wood fuel that has been felled and processed locally where possible.

It's becoming more challenging due to the huge increase in popularity of wood burners.

Hehe

Until you learn that some are chopping trees and ground them to make briquettes because they can make more money than just selling the wood.

Yeah, exactly my concern. What are the briquettes made of (waste product or felled timber) and how much CO2 and energy goes into their process that produces them? Some companies do offer waste wood products, but Lekto don't state what theirs are.

@allyfish, the briquettes, from what I've been able to establish, are made from recycled softwood bark, which is typically a discarded byproduct. No idea how much energy goes into making them.

Unpack some wood logs and briquettes with us:

Leopold finds his greatest pleasure in the colder winter months, when he can indulge in the luxury of basking in the warmth of a crackling fire.

This winter, we started using long burning briquettes for the first time from a company called Lekto, and their nighttime briquettes are excellent if you want a long, slow heat. We were getting about five hours from each log, which was excellent to keep the living room (where our pets often sleep) warm in the early hours. I'm sharing this here because they have a 20% discount at the moment, which is a great saving. 

Link invalid for me.

@Morgan, try this one:

@editor That works. Thank you.

Until recently my only heat was a multi fuel stove, bout 9 years burning wood only, a year on smokeless anthracite over wood, first consideration for me is the cost(I didn't have any cost for 9 years) these are on the high side of that in that one shovel of anthracite nuts over wood should keep an efficient stove burning low overnight, not sure what the environmental trade off is there but a 20kg bag of anthracite nuts is about £20 where I am.
