53 uses & applications of biochar


Soil Amendment

1. Carbon fertilizer

2. Compost

3. Substitute for peat in potting soil

4. Plant protection

5. Compensatory fertilizer for trace elements

Livestock Farming

1% of Biochar for Livestock Feed

Increases energy efficiency of digestion, 77% less dysenterie, 62% animals are calmer and balanced, 77% less odour in barns.

Observation: cells in milk decreased, less streptococcus, less rumen ulcer, better fitness, absorption of gram positive bacteria (botulisme), pesticides, herbicides, reducing odours, fixation of nutrients, and improvement of barn climate.

6. Silage agent

7. Feed additive/supplement

8. Litter additive

9. Slurry treatment

10. Manure composting

11. Water treatment in fish farming

5-10% BC in Litter

Reducing humidity and odours (84%), fixation of nutrients, reducing ammonia and methane emissions, amellorates hygiene, hoof infections

Biogas Production

12. Biomass additive

13. Biogas slurry treatment


Cow Farms:

  • One year after beginning administration; found that cows did not need any veterinary treatment during that time

Swine Farms:

  • Pigs did not need any more antibiotic treatment during the first six months of administration

Chicken Farms:

  • 3 days after beginning of treatment with fermented biochar, vermifugation of round worms took place

  • The mortality rate decreased in a chicken farm, while at the same time a high and continual increase in weight of 90-100g per day was observed



Decontamination of Soil and Natural Water

14. Soil additive for soil remediation

15. Highly absorbing, plantable soil substrates

16. A barrier preventing pesticides getting into surface water

17. Treating pond and lake water

Waste Water and Sewage Treatment

18. Active carbon filter
