Pioneers on biochar – visit to a biochar production farm

Hjelmsäter was one of the first companies to start a production of biochar in Sweden. Production of charcoal through pyrolysis has been around since the medieval times. But here we are talking about modern production, also through pyrolysis, that has been talked about for over 10 years. Now, it seems that a breakthrough is close, thanks to boilers that optimizes the process with computer power, and equipment that make the handling easier.

Effect of biochar on microbial community composition and enzymatic activity

Biochar offers several benefits as a soil amendment, including increased soil fertility, carbon sequestration, and water-holding capacity in nutrient-poor soils. In this study, soil samples with and without biochar additives were collected for two consecutive years from an experimental field plot to examine its effect on the microbial community structure and functions in sandy soils under peach-trees.

New uses for cherry pits makes landfilling a ‘waste of a waste’

Using pits from the Kewadin plant, Cornell researchers experimented with how to convert them to biochar, a charcoal-like, carbon-rich substance made by heating pits in a zero- or low-oxygen environment. Biochar is usually plowed or dug into farm fields and gardens to enrich the soil.

Biochar helps hold water, saves money

Biochar’s benefits for the long-term sequestration of carbon and nitrogen on American farms are clear, but new research from Rice University shows it can help farmers save money on irrigation as well. The study showed that sandy soil, in particular, gains ability to retain more water when amended with biochar.

Dead plants are powering Stockholm

The biochar process is ingenious, turning green waste into heat before returning it to the soil as an agricultural nutrient. No wonder it’s turning a profit.

Biochar makes concrete stronger and more watertight

A team of researchers from the National University of Singapore (NUS) has developed a novel new method to recycle wood waste [as biochar] by incorporating it into cement and mortar mixtures, making the resulting materials both stronger and more watertight.
