What is biochar and why is it reaping such positive climate results on farms and forests?

The nature-based carbon sequestration technology is particularly successful at lowering nitrous oxide emissions.

Biochar could help farmers achieve net-zero greenhouse gas emissions.

A recent review of more than 200 field studies worldwide examined the impact of the nature-based carbon sequestration technology on agricultural emissions. The results were promising.

Made from organic waste, biochar is particularly successful at lowering nitrous oxide emissions, researchers from The Ohio State University in the US found.

The study, published in the scientific Journal of Environmental Quality, highlights other benefits of biochar, including its ability to optimise soil.

The authors hope their research will help promote the commercialised use and adoption of biochar in farming and forestry.

Sewage sludge as feedstock for pyrolysis to be included in the scope of the EU Fertilizing Products Regulation

Sewage sludge can be turned into a safe and valuable phosphorus fertilizer by using it as feedstock for pyrolysis and gasification, resulting in a net positive effect on the climate.

In the EU Fertilizing Products Regulation, sewage sludge was excluded from the list of eligible feedstocks for pyrolysis & gasification materials to be used in agriculture. The reason was uncertainty whether contaminants of emerging concern are eliminated. To address these concerns, EBI’s position paper presents the latest scientific evidence on the elimination of the most important contaminants in sewage sludges, including pathogens, organic pollutants, PFAS, PAHs and microplastics. It also addresses further benefits regarding climate and the direct yield of high-quality phosphorous fertilizers.
