Closing the Loop

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 […]

Waste Not Urine

In his posthumously published 1911 work Farmers of Forty Centuries, USDA agronomist F. H. King documents his travels studying the intensive agriculture of China, Korea and Japan.  Multiple references are made to the efforts of farmers and city-dwellers alike to collect and distribute human waste to nearby farms as a valuable source of ongoing fertility: […]

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 […]

Home-Scale Biogas Production

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 […]

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 […]

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.
