Humans have been making biochar for thousands of years; the basic production process is not difficult. Carbon Gold’s technology has been developed to ensure that the process is as efficient as possible.
Carbon Gold has developed a series of kilns for the optimum production of biochar, which are economical, efficient and easy-to-use.
Biochar can be produced by large plants capable of turning out 10,000 tonnes per year or as a cottage process producing just a small amount of biochar each day. Carbon Gold kilns only operates at the smaller end of this scale.
Yes, the smallest of our kilns, the SuperChar 100 is available for sale.
Yes, the SuperChar 100 is easy to transport in the back of a pick up and can also be moved by a tractor with a forklift.
Well-made biochar, which has been processed into smaller particles, can be applied directly to the soil but activating biochar with wormcasts and mycorrhizal fungi (as with our GroChar range) gets it to work even faster and more efficiently for optimum plant health.
Any dry uncontaminated organic woody material, from small branches to sawn logs, can be used to create biochar. It is important not to use feedstock that may have been contaminated with heavy metals such as old painted wood, which may contain lead, if the resulting biochar is being used to improve soil fertility.
Biochar production does generate some pollutants – such as tars, phenols, carbon dioxide and nitrous oxide – but at far lower levels than would be emitted if the woody biomass was simply burnt. Carbon Gold has developed kilns that minimise these pollutants.
Yes, for example, we supplied a number of inexpensive kilns to organic cacao farmers in Belize, who grow cacao for Green & Black’s.
