Anthroponics

  This post documents our work using urine as a primary nutrient in hydroponic systems. It is a  part of a series of blog posts exploring the historical and modern applications for human urine.  Part 1 is available here.  Part 2 is available here.     Three years ago, in the early spring, I bought two […]

On-Farm Plastic Recycling

From last year’s Cooking with Food Waste workshop to the upcoming installment of the developing Waste Not series, Living Web Farms is making a point to not only reduce waste, but  help change the perspective on waste all together. There is no waste in nature.  As agriculturalists, there is great importance in studying farming practices […]

DIY Activated Carbon

Like everyone else, Living Web Farms is adapting to the changing circumstances of the Covid-19 pandemic.  Expanded farm operations and food donations are now top priority.  We’ve started a new short-form, rough-edit video series for sharing immediately relevant information and a few weeks ago we offered our first of should be many free webcast workshops.  […]

Return to Atomizing Oil Burners

Part One available here The nexus of appropriate technology, circular economy and agriculture is a buffet of challenging, interesting projects.  In 2017 and 2018, our continued work in biochar and gasification, and among other esoteric projects, our work with small-scale plastic recycling, – not to mention organizing the WNC Repair Cafe project – have kept […]

Back to Backyard Biochar

Save for our WNC Repair Cafe project, and a handful of appropriate technology workshops, we’ve been pretty quiet over here at the biochar facility for a little while now. Lately, most of our work has centered on upgrading the liquid components of our method of biochar production: we’re going deeper with our research in wood […]

Atomizing Waste Oil Burners

Update: 10/26/18.  Part 2 available here Summer HVAC season is coming to a close and lately our local scrap-yard has been teeming with old oil burning furnaces. While Asheville residents are replacing oil burners with updated heat pump systems as fast as they can, conscious builders and tradesmen are recycling the used equipment, and although […]

DIY – Make a TLUD Gasifier

By Dan Hettinger, Biochar Facility Manager Last month I wrote a little about the carbon impact of biochar production, and concluded with the assumption that going ‘carbon-negative’ is likely very possible with simple scale ‘backyard’ biochar technologies.  Bob Wells’ immensely popular presentation on the Tin-Man shows an effective DIY method with a single 55 and […]

Closing the Loop – Biochar as Carbon Negative Technology

By Dan Hettinger, Biochar Facility Manager The increase in annual global carbon emissions has stalled in recent years despite strong global economic growth.  In effect, economic growth is no longer coupled with increased carbon emissions.  In 2015, most of the world agreed that we can limit climate change to a rise of 2 degrees Celsius.
