Hello woodfolk, I am designing a portable charcoal/biochar retort for use by professional woodcolliers. I am pretty sure about the way my design will work, but I am after ideas of what people would want from a retort, such as capacity or the maximum weight of the thing. Most of my experience has been in woodland creation and tree surgery rather than charcoal making. I have used a ring kiln a couple of times but a retort is obviously a little different. My main motivation is environmental. ie. local charcoal, produced as cleanly as possible, from sustainable woodlands and not destroying habitats on the other side of the planet. What do members think of the state of the market for charcoal and biochar? What do you think of the current devices out there? I am open to any thoughts really. Although I've thought the design through pretty thoroughly over the last couple of years, I'm sure there will be some things that I haven't thought of yet.

We wondered if this article might interest Arbtalk members ...... Landscapers who plant and protect trees know the active role they and their trees play in mitigating climate change, and this is certainly recognised by decision makers, if not yet budgeted for by all. DEFRA is half way through its Big Tree Plant, which aims to plant a million trees by 2015. A handful of UK cities have pledged to increase canopy coverage in urban areas – London hopes for a 5% increase by 2025, Bristol an impressive 30% increase overall. Natural Resources Wales has undertaken the Wales Urban Canopy Cover Study, which it is hoped will inform how much more needs to be planted and where. Not only do trees have a cooling effect on their immediate atmosphere, play an important role in flood prevention and have a positive effect on health and wellbeing, they are an essential carbon sink. It is estimated that during its full lifetime, a 100 year old broad leaf tree will capture and store over 10 tonnes of carbon dioxide. Indeed, a quarter of a living tree’s weight is locked away - or sequestered - as carbon, which is only released back into the atmosphere when the tree dies, rots or is burnt. read more.....
